I have an alpha cb24 that is leaking water slowly. It seems to be coming from the base of where the DHW flow switch clips on. I could use a little help:
1. Do I need to drain the system before I remove the DHW flow switch?
2. What stops water leaking out around the flow switch? It seems a prety flimsy piece of plastic so I'm not really suprised it leaks.
As you might have guessed I know very little about boilers but I have called somebody out to fix the thing twice (for other reasons) and it has cost me nearly £400 already. I'm beginning to believe them when they tell me it needs replacing but it seems stupid to replace a boiler that's only problem is a slow leak from around the DHW flow switch.
Anybody got any suggestions?
Thanks, Phill.
