Water Tank FAQs

Water Tank FAQs

‘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.

Water Storage Tanks are used across many different industries, which can make purchasing the correct one a little daunting.The following guide may be useful to you – ‘What Water Storage Tank Do I Need?.

Still Unsure? We are always willing to help – just give us a call or contact us here.

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.

An example of 3 x 1 Inch Fusion Sockets fitted to a 155 Litre Flat Tank.

Yes, planned viewing is possible at a number of locations. Please call and allow us time to arrange this for you.

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.

For a more detailed view, we have written an article called 'Why Baffled Water Tanks Are a Must-Have for Window Cleaning and Water Transport' linked here.

Yes. This is possible by using a ‘fusion’ and are available in a number of sizes to suit your application or project. View the range here or read our Fusion Socket Guide here for more information. Just add the required fusion onto your order and once complete, we will be in touch to arrange placement of the fusion/s.

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).

8 Inch Plain Lid
8 Inch Spring Vented Lid

In most instances, it is possible to swap a lid for an alternative but please contact us before ordering unless it is offered as an option on the product page.

Yes, we are able to manufacture the majority of the Water Tank range in a wide variety of colours. You can view our Colour Chart page here

This is no problem, the only consideration you may wish to make when using saltwater is whether you would prefer to use a plastic outlet (know as a fusion) rather than the brass or nickel outlet that come as standard with the range. If this is the case, all you need to do is request that you tank comes 'undrilled' which will ensure a plastic 'wall' separates the metal fusion and the tank contents. The plastic fusion can be added almost anywhere on the tank. Just choose the fusion you require and add to your basket along with the tank. Once your order is placed, we will then in touch to discuss where you wish your plastic outlet to be placed.

The Byelaw 30 Kit is specifically used when connecting a tank to mains water supply. With an insect proof screened vent, as well as preventing backflow of the stored water into the main s(potable) supply, it helps to prevents contamination A Byelaw 30 Kit is required in order to conform to the Byelaw 30 Regulation as it helps to maintain the quality of the water in the tank.

Our water tanks come with manufacturers warranties. They are built to last and a leak is very uncommon. If your tank does spring a leak, there are a number of things to check first. Read our article 'Top 5 Reasons Your Water Tank Is Leaking' here.
