Hi All,
Recently had a new PCB and filler loop fitted to my 30cxi. The filler loop was steadily leaking prior to this, which seemed to be the reason for the system constantly losing pressure and needing to be topped up.
Now that the filler loop isn't leaking, the system is still losing pressure (not consistently, it seems to vary but based on what I cannot determine.) So, I need to call my engineer out but could do with some suggestions for obvious stuff I can check with my own eyes first.
I'm aware that a dodgy pressure sensor, or failing/un-pressurised pressure/expansion vessel could cause the dodgy pressure readings but what I don't get, is where is all the water going. I'm having to top it up from about 0.7/0.8bar to 1.2bar more or less every other day now. So far, I can't find any signs of leak on the system (I still have two rooms that have laminate floor down so difficult to investigate without destruction!) but I'd have thought the amount of water I'm having to replace would mean a leak would be obvious!
None of the ceilings downstairs show any signs of water from above and I can't see any under the boards so far. There is no condensation or damp anywhere either suggesting pooling of water, or damp/musty smells. There is a little bit of air in the system although I'm putting that down to it containing mostly water with very dilute inhibitor, due to the constant filling. As far as I can tell, the entire system, including boiler, radiators and all pipework was new in 2006.
So my initial thoughts are maybe the PRV or condensate pipe are letting water out of the system, or there is a leak I've not found yet somewhere on the pipework. I cannot see anything from the PRV/overflow pipe however the condensate pipe is constantly dripping. I need to isolate the boiler from the system to see if I can identify which side is losing pressure but its been too cold to turn it off the past day or so!
Just how much water out of the condensate pipe is "normal" if such a thing exists?
