Have had to replace the pressure relief valve - unfortunately, the way the boiler was installed (pipes not far enough back away from the heat exchanger) I had to remove the return unit to be able to access the valve. This is where things went a little awry... the by-pass valve (87161064340) fell out from the return unit . I have looked at the hydraulics diagram which looks as though the black cap end goes into the unit first, but obviously need to get it correct and there is no 'flow' arrow to indicate which way the valve should be positioned; any help gratefully received.

Thank you
 
I have a registered plumber coming out this afternoon to sort the boiler out - thanks
 
I hadn't even thought about it, being honest, as I wasn't touching the gas side of things. Thank you for making me realise!

Thanks

Just a quick update - he couldn't make it yesterday as job he was on took longer than expected, but managed to get to us early this morning. All sorted now and we have running hot water and central heating again - may just be the last bits of air to remove from the system over the next day or two... phone number now stored ready for any other boiler problems 🙂

Thank you for educating me on this one - a mistake never to be repeated!
