Underground GRP Tanks FAQs

What is a GRP tank?

Glass Reinforced Plastic tanks are made from high quality GRP material manufactured to BS EN 13280:2001, are suitable for all cold water applications, insulated tanks are also suitable for external applications, and are fully WRAS approved.

Benefits of GRP over steel or plastic

Most GRP tanks are supplied fully pre-insulated with PU foam fully encapsulated within the GRP laminate, GRP tanks come in a wide range of standard sizes and can also be supplied bespoke to suit your specific size and configuration requirements.

Whats the difference between an AB or AG air gap tank?

An AG type airgap provides mains water protection from fluid category 1-4 with standard lid arrangement for an inlet float valve fitted in the body of the tank, and an AB type air gap, also known as category 5, is when a raised float valve housing is fitted with a spill over weir in addition to the overflow in the body of the tank.

When is a 1 piece, 2 piece or sectional tank used?

1 & 2 piece tanks are available from 90 to 12,000 litres, sectional tanks can be supplied from 125 to 2,000,000 litres. Usually where access permits a 1 piece can be used without any assembly needed, if access is restricted a 2 piece tank can be installed and the top and bottom halved bolted together on site. Sectional tanks are for where access restrictions or other conditions deny the installation of one and two piece tanks. They comprise of individual bolt-up panels which are assembled on site.

 

Sizing a float valve for my GRP tank, which one would I need?

A float valve will usually be sized to suit your incoming mains water supply, so if you have a 25 mm incoming mains you will need a 1” float valve. If we supply the float valve with your tank we will size and supply the overflow to suit this.

 

What is a WRAS tank and is it compulsory?

The Water Regulation Advisory Scheme sets legal requirements for the design, installation, operation and maintenance of plumbing systems, water fittings and water-using appliances. These Regulations and Bye laws apply in all types of premises supplied, or to be supplied with water by a water company. All of our insulated GRP tanks are fully WRAS approved, so can be connected to a mains cold water supply. These regulations do not apply where a property uses a private water supply and does not have a supply of water from a water company.

 

There are lots of optional extras on the GRP tanks, what are they and are they required?

Our GRP tanks are usually supplied without any connections, as many customers supply and fit their own. However we can supply a comprehensive range of items including inlet float valves, outlet connections and other fittings to suit your individual application. Please contact us to discuss or request a quote for your requirements.

Do you supply pumps with the GRP tanks?

If you require a booster pump, you must fit a break tank to the incoming mains water supply to connect to the pump set. Our GRP tanks are ideal for break tanks. We can supply a wide range of booster sets where a break tank is needed.

Do you offer a clean & disinfection of tanks which have been previously been purchased?

Yes, we can supply a quote for cleaning existing tanks. We can also arrange to clean and disinfect newly installed tanks as part of the supply and assembly service on all new 1, 2 & sectional tanks.

Benefits of professional onsite assembly of Sectional Water Storage Tanks

The benefits of purchasing onsite assembly for your sectional water storage tank, you will have experienced engineers onsite to assemble your water storage tank, All engineers have valid CSCS cards , asbestos awareness training and certification , confined space training and certification.

We have a national coverage service assembling tanks day in day out & engineers are fully experienced in their field of works

You should have peace of mind that all engineers are solely employed by the tank manufacturer directly and are educated to understand all water regulations in accordance with WRAS and the current water regulations guide & will ensure that your tank installation is meeting all current regulations to save any potential implications post install.

Our engineers will check the whole area including the base to make sure that the environment meets all required criteria to carry out a successful & safe assembly. Engineers will also drill & fit any connections purchased with the tank providing a representative onsite can determine the location that these connections should be fitted.

Not only will you take away the peace of mind that your tank has been assembled to a professional standard, you will also have a fully guaranteed tank which will cover all components & the assembly itself for a full 12 month period from the date of assembly.

By selecting the onsite assembly option, you must agree & ensure that all tank components will be taken to the area where the tank is to be assembled prior to the engineers arrival to site.

Once the assembly is complete, engineers will ask your nominated site contact to check the assembly & sign to confirm that they are happy with the works. Your site contact will be left with a copy of this paperwork which will advise that you must fill the 10 days of the assembly & send evidence of this over to a specific email address, this is very important to do this in order to validate your warranty.
