Baxi 105 he combi problems

memphuklf

Having an issue with the above boiler. We inherited this boiler a few months back when moving into our new home and is about 6 years old. When we moved in the pressure on the boiler was very low and decided to fit a filling loop to be able to top it up. Topped it up to 1.5 and all seemed to be Ok but now seem to have to top it up weekly which knew there was a leak somewhere. Found the leek which seems to be dripping from the diverter valve(hot water and heating both hot). It seems to drip worse when hot water is running. Could anyone give me any advice if the diverter valve is at fault and how much do you think this would cost to repair?

Just had the front off the boiler and it seems it's not leaking from the diverter valve but coming from the back of the nut on the image below. Would this be easy to replace as not sure what it is for.

Found the issue.

I guess the first step it to try and tighten it a fraction.

Mr.Generous

tighten it, or loosen it off (after turning off water and draining pressure) , wrap thread in PTFE tape then re tighten.

Thanks for replying. Think I managed to tighten it a little, very awkward as it's fitted into cupboard with not much room to play with. Will check it in a couple of days to see if it's still leaking and if it is will try your method Mr. Generous.

Ok looks like the initial leak is from the nut just under the diverter main body(top nut on the second picture) dried it off and definitely not coming from the diverter itself. Anyone know what size wrench I will need for this?

Unless you already have a good set of wrenches in doors then i'd recommend a set of adjustable wrenches. 3 different handle lengths from Screwfix @ £8:
