Boiler Losing Pressure

[tambini87]

Hi all,

I'm just looking for some advice before i call an engineer.

I've got a Worcester Junior 28i boiler which is working fine but have noticed it's losing pressure quite quickly. If i topped up the water today, the gage will show as empty in around 2 weeks. But the boiler still works.

I cannot find an obvious leak but hoping someone will be able to give me pointers into what it may be.

Thanks in advanced.

Can you see the safety valve discharge, usually drilled through the wall to outside, beneath boiler

I can yes.

well tie a balloon or freezer bag or similar on the outlet and see if you get any water in there

Thanks mate, will give that a go and will post my results.

if you get water in there you have an expansion problem, a fix that you can do yourself, lots of info in the FAQs on here telling you how to do it
