FAQs - Enduramaxx

Each tank comes with a outlet as standard. The plastic behind the outlet can be removed (‘drilled’) to allow the liquid to run out of the tank and through a tap if you have one fitted. It can also be left ‘undrilled’ which means it remains closed and the liquid cannot come out through this outlet. You may wish the outlet to be left undrilled if you plan to use the tank purely to store water, as an example.

It is possible to choose ‘drilled’ but purchase a ‘plug’ for the correct size outlet which will seal the outlet when required but allow for flexibility in the use of the outlet. Another option is to choose to have the tank ‘undrilled’ and remove the plastic yourself at a later date.

‘Potable’ is a term used to describe a tank suitable for storing water for human consumption. To be classified as potable, the plastic it is manufactured from must conform to the WRAS (Water Regulations Advisory Scheme). For more information on this, please visit the WRAS Approvals website here where they have an information titled ‘What is a WRAS Approval?’.

All our potable tanks adhere to these regulations. It will specify if a tank is potable in the Product Specification section on each product page.

From experience, our customers favor the Baffled Water Tanks for this application.

A Baffled Water Tank has pre-moulded internal walls called ‘baffles’ which helps to control the movement of the water in the tank during transportation of liquid. This also helps to improve the vehicle maneuverability.

The size of tank required is completely dependent on the size of your vehicle and the set-up you require. The most popular Baffled Water Tanks are as follows: 210 Litre upright, 250 Litre upright350 Litre upright and the 400 Litre upright water tank. We do have customers who prefer the larger tanks so this is also an option.

The Baffled Water Tanks are also suitable for use with water-fed poles.

Each Water Storage Tank comes with either a ‘Vented’  or a ‘Plain’ lid as standard.

A vented lid allows air to circulate within the tank, helping to control the pressure within it. This is important if you plan to attach a pump to the tank as without this, the pressure may cause the tank may deform. Often, this type of damage is not repairable.

A plain lid is purely for containing the water and stops air getting into the tank.

See below for an example of either type (Note – the lid may look slightly different depending on what tank you are looking at. Please refer to the individual product for details).
