Hello all,
I have a real problem to deal with. I have recently installed a full underfloor heating system in a very expensive 'new build'. I have run 28mm copper from the boiler to the unvented hot water cylinder approximately 18M away. I insulated the 28mm copper pipework and air tested it prior to the floor screed being laid - all was well. The floor construction is as follows - concrete oversite on which I have run my insulated primary connections. On either side of the flow and return is 65mm of Kingspan insulation. On top of the Kingspan, I laid the red Polypipe plastic crating into which I laid the underfloor heating pipe. On top of all of this is 80mm of screed and then 50mm of limestone paving. Sadly, I have discovered that the flow and return primary pipework is no longer holding pressure. To expose the pipework is a non starter. I have identified an alternative route - however, the fabric of the house is all but complete and I'm going to be extremely unpopular if I start invasive work now. Has anybody had any success with any of the Fernox leak sealing products available? Any other offers?
Yours hopefully, A very worried Huw!
