Hi All,
My wife and I our renovating our first house together and have become a little stuck installing our wet underfloor heating system. Before we end up phoning around local plumbers I thought I'd post on here to see if anyone has any bright ideas.
We've laid the pipes (2 zones), attached the manifold to the wall with the ball and drain/fill valves and run water around the system from the mains (one circuit at a time) as per the manufacturers instructions. We've carefully gone around checking the pipes and there are no signs of any leaks so we started pressure testing the system. At first there were obvious leaks around all the valves so we re-fitted them and tightened them up which has stopped that however the pressure isn't holding for very long. According to the manufacturers instructions the system needs to be at 6 bar for 2 hours. Our system does appear to hold the pressure for this long however whenever we've left it overnight it always drops by around 1.5 bar. We're not sure whether this is normal or something to worry about? We've doubled checked all the connections on the manifold and there are definitely no signs of any water/leaks and the pipes aren't leaking so we're a bit mystified as to the pressure would drop like this.
Any help/advice would be greatly appreciated.
