Sprinkler tank liner replacement recently completed in central London.
Our customer required an immediate solution to help with the water tank repair and water tank lining of their sites main fire sprinkler tank.
Their sprinkler tanks existing tank lining system had failed, subsequently causing a major water tank leak which had flooded their plant room.
Our team attended site within few days of receiving the initial enquiry much to the relief of our customer.
The fire sprinkler tank was initially completely drained and the associated pump system was isolated.
The next step involved removing a panel at a low level to allow our operatives to gain entry into the storage tank.
Removing a low level tank panel also helped elevate the confined spaces risks associated with working within a water storage tank.
This method of entry also ensured that access into the water storage tank wasn’t required from a high level which would of increased the working from heights risk for our operatives.
Sprinkler Tank Liner Replacement Process
Now that our operatives were able to safely gain entry into the storage tank we were then in a position to remove the failed butyl liner.
With the failed sprinkler tank liner removed we then removed the over flow connection and suction vortex.
The overflow connection and suction vortex were manually prepared and over coated with a corrosion resistant epoxy coating which was left to cure.
Our operatives then installed a geo textile matting liner which is required to help protect the new EPDM liner once installed.
With the geo textile liner in place, the new bespoke EPDM liner was installed and securely held in place utilising stainless steel fittings.
The refurbished overflow fitting and suction vortex were then both reinstalled and sealed in place using new gaskets and galvanised steel bolts, nuts and washers.
With the sprinkler tank refurbishment now complete the low level panel was reinstalled and the sprinkler storage tank was refilled, tested and placed back online.
