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?
We recommend conducting ROV (remotely operated vehicle) surveys every 10 years on all fire sprinkler tanks to stay compliant with LPC (Loss Prevention Council) rules and regulations.
These surveys include photos and videos to assess the internal condition of your fire sprinkler tank. Based on the findings, we can recommend any necessary remedial actions to help maintain the long-term integrity of your system.
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.
Installation of Sprinkler Tank Geotextile Matting Bag
Our team begins by installing a geotextile matting bag beneath the new EPDM liner, creating a protective barrier between the internal walls and base of the sprinkler tank.
This matting prevents potential future perforations, safeguarding the new EPDM liner.
Once in place, we retrofit the matting on-site to fit around all key tank connections, such as the suction vortex and drain valve.
After securing the matting, we refit the low-level access hatch or tank panel, fully sealing the tank structure.
We then hoist the bespoke-manufactured EPDM liner from the base of the sprinkler tank to the top, using the stainless steel eyelets pre-fitted into the liner to attach it to the tank’s existing fixings.
With all remedial work completed and both the geotextile matting and EPDM liner securely in place, we refill the sprinkler tank and reinstate the system.
