This mosque had a persistent leak, but finding the source wasn’t straightforward.
Using an inflatable drain b**g, we isolated the downstream pipework and filled the stack with Fernco Drain Dye. This put the faulty joint under pressure and quickly revealed the source of the leak.
Once identified, we cut the stack pipe, installed a structural CIPP patch liner, and reinstated the stack using a shielded Fernco coupling.
No unnecessary excavation. No guesswork. Just a permanent no-dig repair.
