Hi there,
I'm hoping for some advice.
I had underfloor heating installed back in May for a garage conversion. Up until about a month ago, I'd not really used it as the room was warm enough. When I turned it on and set a program, I started to notice lumps in my laminate flooring. When I pulled all the floor up the entire underlay and screed floor was wet.
There are two theories as to how this may have been caused. 1, the screed had not dried completely before the laminate was laid and 2, there is a leak in the underfloor heating.
Since then, the floor has dried out. I have had the heating on which seems to work fine, as in it warms the floor up. But...
I have been advised by the company who did the underfloor heating to isolate the system. Since I did this last week, the pressure has dropped from 2 bar to just below 1 bar. This is according to the gauge that is on the underfloor heating pump, not the one upstairs in the airing cupboard.
The plumber that did the job said that it is 100% not a leak and that the drop of pressure is due to the screed around it that had not dried. Now I am far from an expert but I'm struggling to see the logic that pressure could have dropped by 1 bar in a closed system without there being a leak.
I'd be very grateful if other plumbers could give their thoughts on this. I hope I'm not being fobbed off by a plumber that doesn't want to foot the bill for the repair of my floor. Has anyone else had experience of this?
Many thanks.
Richard
