At Tek-Tanks we get sent quite a few photographs of your installations and nowhere to put them. Well now we have!
As your photographs come in we will publish them here with a brief description. If you have installed a Tek-Tank and not sent us a photo then please do so and we will publish your handywork. Please tell us the make, model and year of build, where the tank is situated and the name of the boat.

Water Tanks
Tek Tanks can supply a wide range of either custom built or standard water tanks suitable for the following applications:
Marine
Leisure motorboats and sailing boats up to 80 feet long.
Vehicles
RV, motor home, caravan, horsebox, hospitality, expedition and fire applications.
Domestic
Loft tanks and header tanks.
Industrial process
Plating tanks, cooling water, research and agriculture.
Cleaning applications
Car valeting, window cleaning, jet wash water supply and chemical storage.
A comprehensive fittings list is available for downloading as well as our Water Tank Design Guide.
Waste Tanks
Waste holding tanks make up about 50% of our business hence there are not many shapes or sizes we have not supplied. Our knowledge of marine holding tank systems is second to none. Holding tank layouts are available on our website and cover probably every variation there is.
We can either build a custom tank to suit the intricate shape of your boat or vehicle, or supply a standard off the shelf unit from a comprehensive stock range.
A comprehensive fittings list is available for downloading as well as our Waste Tank Design Guide.
Fuel Tanks
Tek Tanks custom fuel tanks are manufactured from 10mm thick high density polyethylene and are suitable for diesel fuel only. For petrol applications we can supply tanks from a standard blow moulded range with capacities from 140 litres.
Custom tanks come with brass fittings for the filler, vent, feed and return. Fittings are screwed into female BSP threads welded to the tank. A comprehensive fittings list is available for downloading as well as our Fuel Tank Design Guide.
We are often asked either “What is the advantage of plastic compared with stainless steel or aluminium” so below we have decided to sum up the points we feel are valid to help you decide.
Tek Tanks vs Aluminium
1. Tek Tanks will not corrode when used for waste, Aluminium will. Aluminium tanks could show signs of corrosion within a few years.
2. Aluminium tanks should not used be used for water because there is a possible link to Alzheimer’s disease when used for drinking water tanks.
3. Aluminium tanks have been know to crack at the welds when used in high performance applications.
4. Aluminium tanks need to be painted in a marine environment to combat corrosion, painting adds to the cost and has to be checked and repainted when necessary. Tek Tanks need no further treatment.
Corroded Aluminum Tank5. Aluminium tanks needs to be earthed to the boat’s electrical system. Tek Tanks do not need earthing.
6. Contents are visible with a Tek Tank, Aluminium tanks need a sender.
7. All Tek Tanks fuel tanks are CE marked for added peace of mind.
8. All Tek Tanks fuel tanks will almost eliminate condensation within the tank. Metal tanks have to be kept filled when not in use to reduce condensation. Water in the fuel can cause engine problems.

Tek Tanks vs Stainless Steel
1. Tek Tanks will not corrode when used for waste, stainless steel will. Stainless steel could show signs of corrosion within only a few years.

2. Stainless steel tanks are generally heavier than a Tek-Tanks custom built tank if built from a reasonable thickness of material.
3. Stainless steel tanks are quite often more expensive than Tek Tanks if built by a reputable company.
4. Stainless steel tanks need to be earthed to the boat’s electrical system. Tek Tanks do not need earthing.
5. Contents are visible with a Tek Tank: Stainless steel tanks need a sender.
6. Stainless steel tanks have been known to crack at the welds when used in high performance applications.Tek Tanks have manufactured tanks for performance craft with no failures to date, boats include Sunseeker P1 race boat, several Round Britain boats and the famous blade runner.
7. A Tek Tanks fuel tank will almost eliminate condensation within a fuel tank. Metal tanks have to be kept filled when not in use to reduce condensation. Water in the fuel can cause engine problems.
8. All Tek Tanks fuel tanks are CE marked for added peace of mind.
Tek Tanks vs Flexible Bag tanks
1. Flexible bag tanks have been known to fail at the fittings due to excessive movement of the tank. When half full the contents will move violently in a heavy sea as there are no baffles.
Worn out flexible tank
2. Flexible tanks can be askward to install …they should have slats between the tank and hull so as the hull can breath and also avoid chafing of the bag on the hull.
3. Flexible tanks when used for waste have a reputation of smelling badly. With no vent the contents turn sceptic. Tek Tanks are completely odour free when used for waste due to the 10mm thick walls.

Main Advantages of Tek Tanks
1. Corrosion free. Will not rust or corrode and are not subject to electrolysis problems.
2. Contents can be seen through the tank under most conditions.
3. When used in a fresh water application Tek Tanks water tanks are absolutely taste free.The material used is a food grade polyethylene which has FDA (US Food and Drug Administration) approval. We can support this fact with documentation from Rochling the material suppliers.
4. No smells when used as a waste holding tanks.10 mm thick combat any odour problems. To eradicate smells throughout the whole system, a large breather has to be used, minimum 1″ in diameter, preferably 1 1/2″ in diameter.
5. Lighter in weight than most Stainless steel tanks which is ideal for racing boat applications.
6. All Tek Tanks custom built tanks come with a 5 year guarantee.
7. All Tek Tanks waste tanks comply with the latest ISO standards within the marine industry and can be fitted to boats being built under the RCD (Recreational Craft Directive.) This includes almost every new boat being built in Europe.
8. All Tek Tanks fuel tanks are CE marked and comply with the latest ISO standards within the marine industry.
Westerly Ocean Quest Waste Tank built by Tek-TanksIt is worth checking your tanks thoroughly after the winter layup. Condensation in steel fuel tanks can cause untold problems including corrosion and water in the filters possibly causing your engine to stop. If your stainless or mild steel fuel tank was not left full over the winter layup then it will almost certainly have a small amount of water content. Our climate in the UK provides the ideal conditions for water vapour to condense out on the tank sides. This can often be seen on the outside of the tank, sometimes known as sweating.
Another source of corrosion is tanks sitting on foam or rubber. At Tek Tanks we see many stainless steel, aluminium and mild steel tanks with corrosion problems. Quite often the corrosion can be clearly seen where the tanks have been resting in frames etc. Moisture collects in these areas and is unable to dry out. If your tank is sitting on foam or rubber, then it would be worth checking and even replacing of possible with a non absorbent or closed cell product.
Tek Tanks polyethylene tanks do not suffer with corrosion problems and almost totally eliminate condensation, within fuel tanks.Every Tek Tanks custom tank comes with a 5 year warranty as standard and peace of mind with our CE certification. Should you steel or aluminium tank have a leak, then give us a call for a quote…. you never know, we may have already done one for your model of boat.
In May 2009, Tek Tanks built their smallest tank to date.
Measuring : – L x 200mm W x 100mm Hx 100mm, holding just under 2 litres.
The tank is used for diesel within a Eberspacher heater in the Open 60 Race within an Owen Clarke boat, built in 2007, called Soren Gold.
