I've been in my extended home now since September and I'm finding air in my towel rail every week. I have a Worcester Bosch Greenstar 35 CDi with TRV's on every rad except bathroom, which is a very tall towel rail. Unfortunately, the system was installed by the bert and ernie of local plumbing and we've repaired numerous leaks upon occupation. I've recently lagged all the pipes under the ground floor, so I'm sure there is no glaringly obvious leaks present. However, we did run out of money when completing the extension, so we didn't finish the en-suite. Therefore, we have to isolated ends where a second (smaller) towel rail should be. I recharge the system to 1.2 bar (recommended by W.B.) and always bleed a warmed system with heating off!
The system is in copper, therefore is my only solution checking every joint? Also, if I've got to get them back or have a plumber look at it, what's an acceptable figure for the pressurised test of the pipework?
Any help anyone can afford me would be greatly appreciated.
