Gloworm cxi30 boiler losing pressure (v slowly)
- Thread starter H2O1969
- Start date
It was losing 0.1 bar over 30 days. After some work on the boiler including the fitting of a new pump, it is now losing 0.1 bar over 7 days. The only possible sign of leaking is a salt deposit (white/flaky) on a 21 mm nut under the boiler on the left hand side.
Thats really quite a small leak. You could go down the road off trying some leak sealer in the system. Normally a last resort,but if you've check all rads etc i'd give it a go.
