PRV on W/B Greenstar 28i Junior

[leelister6]

Got a customer with a constantly leaking PRV. Just had a look through the manual and it says the hydraulic block has to be removed to replace! Has anyone done one of these and can it be changed without stripping half the boiler out?!

went on the worcester one day course and they said it was possible - even let us do one in the training van - but i am sure theres must have been moded in some way as the one i did on a boiler a few months later was a right pain - i ended up chiseling the plaster off the wall behind to give me space to remove the valve.

It's easier to drop the boiler off the wall, if its possible. Taking the hydro block out just causes loads of leaks. I've done a couple of these and just dropped the boiler off the wall and changed that way.

It is a pain, I still cant believe they ever though it was a good place to put it.

If the pipes are not rising, you can get your hand up the back if you cut and disconnect the cold. Quicker than lifting it off.
A stupid place to put them tho.

Undo the nuts at the bottom undo the screws on the flue pull the bottom out and swap it. Not the easiest but worcester do like to make prv's a pain I think its the 240 who the hell thought of that.

not done this before. but read on another post to drill out the rivets from underneath and take the bottom plate off and change it that way and once done rivet it back up.

Sounds like a plan to me!
