I would be great-full if any one has any advise on pin pointing where I could be losing pressure in my CH system.
I have a 2 1/2 year old Sabre 29 HE Condensing Boiler which seems to be losing pressure by the day, approx 3/4 Bar.
Before I noticed this the system usually needed a wee top up every 3 months or so but not a lot.
I've checked the RV pipe outside and it shows no sign of the valve passing.
I've checked the pipework under the ground floor (All wooden) and I see no obvious sings of water/dampness. The pipework below consists of a mixture of HEP20 and copper, the newer HEP20 is lagged with foam insulate and I've checked all runs for signs of Rodent damage.
At the rate the pressure is being lost I had expected to see obvious signs of a leak somewhere, to my disappointment I have found nothing.
The only place I find dampness of any sort is from the condensing pipework outside but given that it's clear looking and the CH radiator water is a cloudy grey I'm assuming it's just condensate. ?
I've just stuck 500ml of Fernox sealer into the system but I'm not holding out much hope at the rate I'm losing pressure.
Any idea's where I could be losing the pressure from ?
Should I expect to see dampness at the location of the leaking pipework (If that's what's wrong)
I haven't lifted any upstairs floors to check the pipes because quite frankly I'd have expected to see a dirty damp stain on the downstairs ceilings had the leak been upstairs.
Your help and advice would be appreciated
