The swimming pool filtration system repair which kept a leisure centre’s head above water

When plastic PVC pipework which formed part of the swimming pool filtration system in a British leisure centre developed a 2” crack, a repair looked impossible until Sylmasta swam to the rescue.

The section of pipework in question had for many years been resting on a steel bracket. Over time, this had caused the PVC to weaken and sag, which ultimately is what led to the problematic crack developing.

What made the leak so challenging was the location of the pipe. It was 3” off the ground and surrounded by other components of he swimming pool filtration system, making access for a repair extremely difficult.

Once that problem had been overcome, next was the fact that the crack itself was at the bottom of the pipe, facing towards the ground. This severely restricted the sort of pipe repair that could be carried out, not to mention that if the pressure was turned off, the person carrying out the repair from above could no longer tell exactly where the crack was without water gushing from the hole.

The maintenance company responsible for the leisure centre would normally have two repair methods for a leaking pipe in a swimming pool filtration system. The first would be to remove the damaged section and plastic weld it. If the damage was too severe, they would simply replace the pipework.

To remove this particular section of pipe however would have required the disassembly of half the filtration system. It would have been a time consuming and costly exercise which would have required the closure of the swimming pool to complete.

What the maintenance company needed was a product which could carry out a permanent, live leak repair within a confined space. After seeking technical assistance from Sylmasta, we were able to supply a Universal Pipe Repair Kit to fix the leaking PVC plastic pipe.

Because water pressure needed to be maintained during the repair, Wrap & Seal Pipe Burst Tape was used to seal the leak. It is normally recommended that Wrap & Seal be stretched to the maximum of 300% its length the provide a tight seal around the leak area, where it will fuse into a solid rubber band capable of withstanding pressure up to 30bar.

With just 3” to play with between the pipe and the ground, the maximum stretch was unachievable. Not that this mattered as the Pipe Burst Tape was still more than capable of repairing the leak. It was then overwrapped with a SylWrap Pipe Repair Bandage, which set rock hard in 30 minutes for a permanent solution. The impact resistant layer provided by the Bandage ensured that the steel bracket would cause no further damage to the PVC plastic pipe.

So impressed with the speed and ease of repair were the maintenance company that they have subsequently recommended that leisure centres and swimming pool servicing companies take stock of SylWrap Pipe Repair Kits for any future emergencies.

“Leaks often occur at times when spares are challenging to obtain, such as evenings and weekends, so I suggested they consider stocking SylWrap products as a solution for fixing a leaking pipe quickly as soon as it is reported.”

In the future, these companies may benefit from taking on the SylWrap Pipe Repair Contractor Case. Each case contains enough products to carry out up to six repairs at a cheaper cost-per-repair than when buying inidividual Universal Pipe Repair Kits. They are easy to store either on site or on the van, providing an on-hand solution for whenever emergencies arise.
