Butyl Rubber / EPDM Replacement Sprinkler Water Tank Liners
In some cases corrugated cold water storage tanks and many variations of sprinkler cold water storage tanks can only be relined using a Butyl rubber or EPDM liner (Ethylene Propylene Diene Monomer rubber). Old sprinkler tank liners can begin to leak or become damaged causing a number of potential problems.
Echo Square have extensive experience in fitting high quality replacement EPDM liners in all types of liquid storage tanks where a coating system would not be suitable.
Echo Square can provide a new liner to existing rubber-lined cold water storage tanks. We offer a full installation service whereby the old failed liner is removed and all fixing flanges can be replaced along with their respective nuts, bolts and gaskets to ensure the longest possible service life. The new EPDM sprinkler tank liner is installed on top of a geotextile matting layer for additional protection. Finally a thorough visual inspection is carried out prior to refilling the sprinkler tank.
All replacement liner works are guaranteed for a minimum period of 10 years upon completion against leaking.

When should you replace your Sprinkler Tank Liner?
ROV (remote operated vehicle) surveys are recommended to be carried out every 10 years on all fire sprinkler tanks in compliance with the LPC (loss prevention council) rules & regulations.
These surveys incorporating photos & videos can help ascertain the internal condition of the fire sprinkler tank where further recommendations can then be made in relation to any remedial actions which may need to be carried out to ensure the long term integrity of your sites fire sprinkler tank.
Some of these recommendations may include the following:
– Refurbishment or replacement of the sprinkler tanks roof purlins
– Refurbishment of ancillary items within the fire sprinkler tank such as the the suction vortex & corroded tank panels
– Replacement of all gaskets and seals
– Replacement of the failed butyl or EPDM liner due to deterioration
– Installation of a low level access hatch to ensure safe access into the structure for future maintenance.
– Replacement of faulty ball valves
Echo Square are able to assist in carrying out all of the works above including ROV sprinkler tank surveys when required.
How are Sprinkler Tank Linings replaced?
Following the initial onsite survey of the sprinkler tank which requires relining we can accurately determine what size replacement sprinkler tank liner needs to be supplied as well as what additional ancillary items are required before our operatives attend site.
The required EPDM tank liner is made off site and manufactured to the exact size of the sprinkler tank which requires lining.
We would then arrange a date for our operatives to attend site with our client.
Upon arrival to site our operatives will present our client with our site specific risk assessment and method statement, and attend any health & safety site induction which our clients health and safety representative may require our operatives to carry out.
Our operatives will then change into all required PPE and locate the fire sprinkler tank they will be refurbishing.
All electrical equipment such as the sprinkler tanks pumps and power supply as well as the sprinkler tanks inlet valve will be isolated.
Our operatives will then commence the draining of the sprinkler tank, this could take anywhere from a couple of hours, up to a number of days depending on the capacity of the structure.
Once the draining of the structure has been completed our operatives will begin setting up all required confined spaces equipment such as forced air ventilation, Lighting, and a tripod and harness. (if required)
Our operatives will then access the sprinkler tank either via a low level access hatch or by removing a sprinkler tank panel as close to the base of the sprinkler tank as possible to allow for easier access.
Following entry into the sprinkler tank our operatives would then begin removing all remaining water and sediment from the base of the sprinkler tank utilising a submersible pump and wet vacuum.
The existing failed sprinkler tank liner is then cut into sections and removed from the sprinkler tank via the low level access hatch or the area where the sprinkler tank panel has been removed.
All required additonal remedial works are then carried out such as the refurbishment of the sprinkler tanks roof purlins, replacement of gaskets and seals and the the installation of a low level access hatch should one not already be installed.
Installation of Sprinkler Tank Geotextile Matting Bag
A geotextile matting bag is then installed underneath the new EPDM liner to act as a barrier between the sprinkler tanks internal walls & tank base.
The purpose of installing a geotextile matting bag behind the EPDM tank lining is to ensure the new EPDM liner is protected from any possible future perforations.
Once installed, the matting bag is retrofitted whilst in situ to accommodate for all tank connections such as the sprinkler tanks suction vortex and drain valve.
Now that the matting bag has been securely fitted into place the low level access hatch or tank panel is then refitted, completely sealing the sprinkler tanks structure.
Our operatives are then in a position to begin hoisting the new bespoke manufactured EPDM liner from the base of the sprinkler tank until it is in place at the top of the sprinkler tank.
The EPDM liner is hung by the sprinkler tanks existing fixings by the stainless steel eyelets which are pre fitted into the EPDM liner.
Finally, now all required remedial actions have been completed and the geotextile matting and EPDM liner has been fitted the fire sprinkler tanks relining and refurbishment is complete and the sprinkler tank can now be refilled and the system reinstated.
Echo Square Service’s have the capabilities to carry out all types of water tank relining and sprinkler tank lining replacement works nationwide.
