Three main types: suction hoses draw diesel from a source below the receiving tank; gravity hoses are used where fuel flows downhill; dispensing hoses are used in refuelling stations with specialist fittings and anti-static properties.

Hoses made from reinforced rubber or synthetic compounds with abrasion-resistant coatings and UV protection. Regular inspection and following manufacturer guidelines extends service life.

Consider your required flow rate, transfer distance, elevation changes, fuel viscosity, and the inlet/outlet diameters on your tank, pump, and nozzle. Thicker fuels may need larger diameter hoses in cold temperatures.

A bunded tank is an oil tank within an oil tank. Any spillage from the inner tank is contained by the outer tank, preventing environmental pollution. Required at most commercial, industrial, and domestic premises.

A single container with no secondary containment. Not suitable for commercial, industrial, or institutional premises, or domestic installations over 2,500 litres, unless within a bunded area. An Oil Tank Risk Assessment must be carried out by a competent person (OFTEC TIB3).

Tanks under 3,500L must be at least 760mm from a boundary. Where not achievable, a 30-minute fire-resistant wall extending 300mm above and beyond the tank ends is required (OFTEC TIB3 / BS5410). For 3,500L+, contact your local Building Control Officer or OFTEC.

Tanks under 3,500L should not be within 1.8 metres of a flue outlet or non-fire-rated wall/eaves. Where not achievable, a 30-minute fire-resistant wall is required. For 3,500L+, contact your Building Control Officer.

Never in a habitable area. If installed internally, the tank must be in an enclosed chamber. Contact your local Building Control Officer or OFTEC for detailed requirements.

No.

All tanks supplied by Tanks.ie are manufactured from Medium Density Polyethylene (MDPE) — excellent chemical and impact resistance, resistant to the long-term effects of fuel.

A flat, level, fire-resistant base. Concrete slabs must be at least 50mm thick and extend at least 300mm beyond the widest points of the tank. Piers or pillars are not suitable.

Yes. All tanks sold by Tanks.ie incorporate UV inhibitors, preventing UV rays from permeating the tank and degrading the fuel.

Yes — consult an OFTEC registered installer first. Common methods: false walls (leave access for maintenance) or landscaping with shrubs. Keep plants well-maintained to avoid fire hazards.

Dipsticks are not sold separately but are standard on Harlequin tanks between 650 and 2,700 litres. We do not sell gravity feed kits due to the high risk of accidental discharge and because their use is illegal at many installations.

A 32.5% aqueous urea solution used in SCR systems to reduce NOx emissions from diesel engines. Converts NOx into harmless nitrogen and water vapour. Non-toxic and biodegradable.

No. AdBlue is corrosive and must never be added to a fuel tank. If accidentally added, seek professional help immediately to drain and flush.

Yes, but protect from direct sunlight, extreme weather, and impact damage.

No.

All diesel dispensing tanks are bunded. Doors can be locked with a key or padlock. Advanced models include fuel management systems with key fob authorisation.

Diesel (D) to British Standard BS2869, and Bio-Diesel up to 5% bio-element concentration.

No. Dispensing a non-approved fuel could result in serious injury or death.

Generally 6-12 months, depending on fuel quality, storage environment, and tank seal quality.

No. Neither can work without pump pressure, which a hand pump or gravity-fed tank cannot provide.

Single phase 240v mains connected to an RCD. All mains installations must be carried out by a qualified electrician.

• Durable — strong, hard-wearing, repairable. Plastic tanks are often unusable once damaged.
• Robust — very hard to damage, reducing leak risk.
• Secure — harder to break into.
• Customisable — made to specific shape, capacity, and dispensing requirements.

Minimum lifespan target is 10 years. Coastal environments accelerate corrosion.

De-aerates fuel before combustion — cleaner burn, reduced emissions, better cold weather performance. Allows the tank to be positioned lower than the burner and up to 30 metres away. Note: unsuitable for vaporising burner installations. Self-priming. No batteries or mains power required.

Float gauges provide approximate readings (full, 3/4, 1/2, 1/4) — not precise due to the rounded base of most tanks. Smart ultrasonic gauges like the SENSiT provide readings accurate to within a few litres via a smartphone app.

We recommend keeping at least 12 inches of oil in the tank at all times. Running too low risks disturbing sediment which can clog filters and pipes.

No. The SENSiT provides indicative level data (approximately plus or minus 5% accuracy) to assist with monitoring. It does not actively prevent run-outs or overfills and is not a fail-safe device.

Kerosene (C1/C2), Agricultural Fuel Oil (A2), Diesel (D), and Water.

Confirm the tank is flat, level, within 200 metres of the receiver, and no taller than 3 metres. For pre-drilled tanks remove the existing tube; for undrilled tanks drill a 32mm hole at a flat level point. Fit transmitter base with two screws. Measure tank height and set receiver switches using the tank height chart. Pair by holding transmitter white dot to receiver black dot for 20 seconds until all 10 bars flash. Screw in transmitter. Allow up to 2 hours for first accurate reading. Support: warranty@sensor-systems.com

13 amp single-phase mains with an RCD. All mains installations must be carried out by a qualified electrician and inspected regularly.

Diesel (D) to BS2869, and Bio-Diesel up to 5% concentration. Harlequin BioFuel Stations support BioDiesel blends up to B100.

No. Diesel only. Dispensing a non-approved fuel could result in serious injury or death.

No. Contact your local authority for advice on disposing of petrol and similarly hazardous liquids.

Hydrotreated Vegetable Oil (HVO) is a renewable fuel derived from vegetable oils and animal fats. Compatible with existing diesel infrastructure, it reduces greenhouse gas emissions by up to 90%, reduces NOx by up to 27%, particulate matter by up to 84%, and has a shelf life of up to 10 years.

Yes — HVO has a higher cetane number (70+) vs diesel (around 50), meaning better combustion and greater efficiency. Can be stored up to 10 years or more when stored correctly.

Many newer appliances support both heating oil and HVO. Existing boilers may need modifications including replacing the burner, changing nozzles, and checking all fuel-carrying components and seals. Check with your appliance manufacturer.

A transportable diesel tank should be stored in a secondary containment area as most are single skin. They are designed for transporting fuel to a worksite to be fully discharged.

Potable tanks store water safe for human consumption (WRAS approved). Non-potable tanks store water for toilets, gardens, and industrial use. IBC containers suit hazardous liquids. Rainwater harvesting tanks collect rainwater for non-potable reuse. Contact our team for help choosing.

A good quality polyethylene tank should last 10-20 years. A steel tank should last over 30 years. Regular inspection and siting on a solid base away from direct UV exposure all extend lifespan.

Potable tanks are WRAS approved with food-grade polyethylene lining — safe for human consumption. Non-potable tanks store water for toilets, washing machines, gardening, and commercial use. The key difference is the type of plastic lining used.

Yes — prevents freezing in Irish winters, reduces heat loss, saves energy, and helps ensure regulatory compliance.

Signs of hard water: staining on sinks and baths, limescale on shower heads and kettles, clogged pipes and radiators, soap being less effective. Hard water is very common in Ireland.

• 100% limescale removed
• Washing machines work better with less detergent
• Softer hair and skin
• Longer appliance life (kettles, dishwashers, washing machines, electric showers)
• Energy savings and reduced spend on cleaning products

Generally yes for healthy adults, but softened water contains a small amount of sodium. People on a low-sodium diet and babies should not drink softened water. Always maintain one unsoftened tap directly from the mains.

Hard water flows through resin beads that trap calcium and magnesium and exchange them for sodium ions. Once full, a brine salt solution regenerates the beads, flushing the minerals down the drain. Refill with salt every 6-8 weeks.

A water purification process using a semi-permeable membrane to filter out contaminants, sediments, chlorine, salt, and microorganisms at a molecular level. Removes the fluoride and chlorine added to tap water, producing great-tasting drinking water. Replace filters every 6-12 months; system lasts up to 10 years.

An economical, chemical-free way to safeguard drinking water. UV light permanently alters the DNA of bacteria, viruses, and protozoa. Effective against 99% of microorganisms with no chemicals and no change to water taste. Replace UV lamps annually (9,000-hour lifespan).

On mains water with bacterial contamination and well water that can become contaminated seasonally due to rainfall, septic tank leakage, or animal waste.

Highway bowsers are for dust suppression and road maintenance. Site bowsers are portable tanks for construction sites — dust suppression, concrete mixing, equipment cleaning. Plant watering bowsers are designed for gardens and nurseries with precision dispensing and adjustable nozzles.

Depends on your location, tank size, and purpose. Tanks in designated areas may face stricter rules. Always check with your local planning authority before installation.

Deep enough to sit below the local frost line to prevent freezing, and above a high groundwater table to prevent floating. Consult local authorities and installers for your specific area.

Glass fibres fused with resin create an exceptionally strong, lightweight composite that resists corrosion, most chemicals, and UV degradation. WRAS approved for cold water storage. Minimum lifespan of 25 years — significantly longer than standard plastic tanks. Available from 90L to 2,000,000L in 1-piece, 2-piece, and sectional formats.

Flexible, collapsible containers for storing and transporting water where space efficiency and rapid deployment are essential — emergency response, remote construction sites, agriculture, and firefighting. Standard PVC bladder tanks cannot store fuels or certain acids.

Collects and stores rainwater for reuse — watering plants, washing cars, cleaning outdoor spaces. Reduces tap water consumption and bills. Rainwater is naturally soft and chemical-free, making it healthier for plants.

Not without proper treatment. Rainwater is untreated and can contain dust, pollen, bird droppings, and air pollution contaminants. Suitable for garden and outdoor use only.

All outdoor uses: watering the garden, washing cars, cleaning patios and driveways. Indoors: flushing toilets and feeding washing machines. Not suitable for drinking, showers, or baths without UV filtration treatment.

Yes — collecting rainwater from your roof is generally legal and encouraged for gardening, flushing toilets, and washing vehicles. No special permits are typically required for domestic collection.

Only when gravity cannot move wastewater to the main sewer — for example if sewage is below the sewer level or a ridge blocks gravitational flow.

Annual servicing is recommended — emptying and cleaning the tank, removing blockages, and replacing faulty parts promptly.

10-15 seconds per cycle until the float switch detects the water level has dropped. A pump that runs constantly may need servicing or replacement. Average lifespan is approximately 10 years.

Allow 150 litres per person multiplied by the number of occupants for 24-hour storage capacity. Contact us for commercial sizing advice.

Domestic and commercial wastewater systems, separators, pump stations, hot water cylinders, and rainwater harvesting systems. Also tank emptying, desludging, and facilities management.

Water is directed into the silt trap basin upstream of the soakaway. Silt and sediment settle to the bottom; filtered water flows through to the drainage system. Without a silt trap, silt would clog pipes and soakaway systems.

Glass Reinforced Plastic tanks manufactured to BS EN 13280:2001. Suitable for all cold water applications, fully WRAS approved, available in 1-piece, 2-piece, and sectional formats.

An AG type provides fluid category 1-4 protection. An AB type (category 5) has a raised float valve housing with a spill-over weir — a higher level of contamination prevention.

Once a year as a general rule. The contractor must be registered to carry out the work.

No. Rainwater increases the flow rate and prevents adequate settlement of solids, causing pollution and health hazards. Only grey water and black water should connect to the septic tank.

At least 7 metres from any dwelling, and within 30 metres of an access point for emptying.

Yes — register with your Local Authority at protectourwater.ie. There is a 50 euro registration fee.

Only if your system discharges directly into a watercourse. Standard soakaway systems remain legal.

• Anything other than bodily waste and toilet paper
• Grease or oil down any drain
• Paints, solvents, or chemicals
• Caustic soda or drain cleaners
• Rainwater

A sewage treatment plant produces clean effluent safe for direct discharge to a watercourse. It requires electricity and regular servicing. A septic tank needs emptying once a year, uses no electricity, but produces polluting effluent that must go to a soakaway. Septic tank discharge direct to watercourses is no longer permitted.

• Environmentally friendly — natural biological processes
• Preserves your drainage field
• Produces effluent you can sample to verify treatment quality
• Long lifespan and lower risk of blockages

A pit or trench filled with gravel or porous material that allows treated water to percolate into the ground. Required for septic tank discharge — not necessary for sewage treatment plants which produce effluent safe for direct watercourse discharge.

Up to 20 years with proper maintenance. Avoid flushing kitchen roll, food waste, nappies, wipes, grease, fats, oils, or sanitary products.

A grease trap collects fats, oils, grease, and starch (FOGS) before they enter the main sewer system. Poor FOGS management causes drain blockages, bad smells, pest infestations, and potentially heavy fines or business closure.

Yes. All food service establishments must have a licensed, regularly serviced grease trap. Irish Water requires a licence to discharge wastewater into the public sewer, and compliance includes a functioning grease trap. This applies to cafes, pubs, restaurants, takeaways, bakeries, and staff canteens.

No. Fats, oils, and grease removed from a grease trap can legally only be disposed of using a licensed waste removal contractor.

An underground tank that stores wastewater and sewage with no outlet — requires emptying by a tanker typically every 40 days. Used where connection to a sewer is not possible and soil conditions prevent soakaway installation. Far less practical than a septic tank which only needs emptying once a year.

A distribution box divides the effluent flow from a septic tank into two or more percolation areas, ensuring even distribution across the drainage field. It is a critical component — if it fails you risk percolation field failure.

We stock hand fuel transfer pumps for manual, low-volume transfers; battery-powered fuel transfer pumps for portable operation on site; and electric fuel transfer pumps for mains-connected, higher-volume dispensing.

We stock a range of flow meters for diesel dispensing. Flow meters require adequate pump pressure — they cannot be used with hand pumps or gravity-fed systems. None of the flow meters we sell are certified for fuel resale (Weights and Measures certification required for that purpose).

We stock submersible water pumps for wells, boreholes, and flooded areas; clean water pumps for transferring uncontaminated water; cold water booster sets for increasing mains pressure; and water controllers for automated pump management.

A booster set increases water pressure in a plumbing system where the mains pressure is insufficient. Commonly used in multi-storey buildings or commercial premises. GRP break tanks are often used alongside booster sets.

Effluent pumps remove grey wastewater after solids settle — for residential and small commercial use. Macerator/grinder pumps grind solid waste into a slurry before pumping — used where waste needs to travel uphill or over long distances. Submersible sewage pumps operate submerged in sewage, handling solids without blocking.

Signs of a problem: dirty or brown water at the discharge point; the pump is not running or struggling; constant running without switching off; sewage backing up into the building; smell of sewage; no fluid emptying from the holding tank; or no power to the pump. Contact us to arrange a service visit.

An Intermediate Bulk Container (IBC) is a large reusable industrial container for the transport and storage of liquids, semi-solids, and solids. Typically holds 275-1,250 litres, sits on a pallet for forklift handling, and is available in HDPE plastic or stainless steel.

A wide range of liquids including water, chemicals, food-grade liquids, oils, and hazardous materials. The material (HDPE vs stainless steel) determines what it can safely store. Always check compatibility with the specific liquid before use.

Chemical storage is regulated under the Chemicals Act 2008, associated regulations, and the SEVESO Directive for larger quantities. You must ensure tank material is chemically compatible with the substance stored, secondary containment (bunding) is in place for hazardous liquids, and appropriate safety data sheets and risk assessments are available. Contact the Health and Safety Authority for specific requirements.

A tank that stores a liquid chemical for controlled, measured injection into a water supply, wastewater system, or industrial process. Commonly used in water treatment (chlorination, pH adjustment), agricultural applications, and industrial cleaning systems. We stock dosing tanks from 200 litres upward.

A boot bath can be ideally used at the entrance to poultry units, piggeries, dairies, and other livestock facilities to disinfect, clean, and decontaminate boots before entering. This helps control and prevent the spread of disease between areas.

Sheep dip tubs are used to fully immerse sheep in a dipping solution to treat and protect against external parasites including sheep scab, ticks, lice, and blowfly. Always follow manufacturer and veterinary guidance for correct concentration and immersion time.

We stock cattle drinkers, sheep and lamb drinkers, and multi-species troughs in a range of sizes. Key considerations are the number of animals, water consumption rate, and whether you need frost-protection features. Contact our team for sizing guidance.

Slurry tanks store animal waste (dung, urine, and water from livestock units) for later spreading on land as fertiliser. In Ireland, slurry storage and spreading is regulated under the Good Agricultural Practice (GAP) Regulations — all farms must have adequate storage capacity to comply with closed spreading periods.

The GAP Regulations require a minimum storage capacity (typically 16-26 weeks depending on region and farming system) and restrict spreading to certain times of year — closed spreading periods apply from October to January in most areas. Contact Teagasc or your local Department of Agriculture office for requirements specific to your farm.

Typically polyethylene (PE), which offers good resistance to liquid fertilisers such as UAN (Urea Ammonium Nitrate) solutions. Always confirm tank material compatibility for the specific fertiliser product being stored.

We stock a range from compact domestic units to large agricultural and commercial storage. All are designed for outdoor use with weather-resistant construction. Can also be used for smokeless fuel, wood pellets, and briquettes. Keep bunkers dry and well-ventilated to maintain fuel quality.

Kingspan Klargester is one of the world's leading manufacturers of wastewater treatment systems with over 65 years' industry experience. Their range covers sewage treatment plants, septic tanks, cesspools, fuel/oil separators, and grease traps.

The BioDisc uses a Rotating Biological Contactor (RBC) system with three stages: primary settlement where solids settle; Biozone 1 where microorganisms on the RBC break down waste; Biozone 2 with final settlement producing clean effluent suitable for discharge to a watercourse.

Every 12-18 months as a general guide, though frequency depends on household size, water usage, and tank capacity.

The Alpha is light, watertight, and strong with easy handling and minimal visual impact. The Gamma prioritises environmental sustainability — easy to install, durable, strong, and lightweight.
