Water Leaking From Combi Boiler Overflow After Replacing Expansion Tank and Pressure Release Valve

Postby russellfl » Tue Nov 19, 2013 10:47 am

Hi, I have some water coming out of the combi overflow. I have had the expansion tank and the pressure relief valve replaced but i still get some water in a bag I taped onto the pipe. Is it normal to get some water coming out of the overflow?

Before I had the items changed I was topping up the boiler dailly but the pressure is much better now. About half a cup has leaked out in one day, do I still have a problem and if so what else could it be?

Any help gratefully accepted
