I changed the diverter valve (including the diaphragm) about a year ago so I hope it`s going to be OK.
Fingers crossed! :wink:
Yes, I`m saving up for a new boiler because it`s old and the price of gas

A full turn of the adjuster screw breaks and makes contact every time now.
Thanks again
Great website :lol:
