Hello all,
I've just had builders lay 65mm sand and cement screed on my wet underfloor heating pipes. Following a successful overnight pressure test, the UFH remained pressurised at around 4.5 bar as the builders began to lay the screed.
I've just looked at the gauge on the manifold and I can see it's now 9.2 bar a few hours after the builders finished.
I'm guessing that this large increase in pressure is due to the elevated temperature of the screed curing.
I'm now a little concerned that the pressure may continue to increase above the manifold's stated limit of 10 bar.
Unfortunately, the manifold is located in the middle of the screened area so I don't want to go and release some pressure unless it's absolutely critical.
Does anyone who has seen something like this have any advice or reassuring words they can share?!
Thanks!
Chris
