Why does your fire sprinkler water storage tank need maintenance? 

Ensuring that your facility has a safe, compliant and relaible water system is required by law in the UK. This includes making sure the water storage tank used to supply your fire sprinkler system is safe from waterborne bacteria. A fire sprinkler system is of the uptmost importance also, as this system will be used in case of emergency.

Fire sprinkler tanks often require maintenance (relining, repair or replacement) due to excessive corrosion of the tank walls. Once corrosion occurs, it progresses quickly and can lead to a number of risks such as water storgae tank leaks, water damage and the prescence of waterborne bacteria such as Legionella. Excessive corrosion usually occurs if the tank lining was not coated upon installation, or if the original lining has started to corrode. The most common causes of fire sprinkler tank problems are:

Fire sprinkler tank corrosion

Corrosion most commonly occurs on the walls of the fire sprinkler tank and around the area where the tank base joins concrete. As the corrosion begins to progress, it can lead to holes in the sprinkler tank which will subsequently cause water loss. Water loss can then lead to water damage in the bulding.

Fire sprinkler tank relining

If the lining of your fire sprinkler tank is failing or no coating was added during installation, this can also lead to corrosion and subsequent water loss.

Butyl 'bags' 

Butyl bags (a type of water storage tank lining used for specific water storage tanks) can lead to a build up of stagnant water in between the lining and tank wall. A build up of stagnant water can lead to harmful waterborne bacteria and leaks or corrosion.


These problems are often noticed by the facilities manager or outlined during a Legionella Risk Assessment.

Tank Reline completed a project for us recently. They were very professional, organised and most importantly in today’s climate very competitively priced. From start to finish the project ran perfectly and they always recommend relining tanks over a full replacement, I would use Tank Reline every time. Also we and our client were very impressed with the photographic reports produced and thought this was a good touch to a great job.
