Replacing Pressure Relief Valve

[clf-gas]

DOH!!! what am I thinking
we can check the loop now, disconnect one side and see if water is still comming out.

Issolating the cold feed is to check DHW HE

sorry........ I'm a simpleton

attached is what the bottom of my boiler looks like - which bits do I turn again?

 

[clf-gas]

look under the boiler at the top of pipes, the brass valves, issolations facing front. yellow in the middle is gas far left and right turn 1/4 turn, blue handle second from right cold feed, turn half turn.

 

[clf-gas]

Undo the loop where indicated, is water still flowing?

 

[PlumberNot]

U mean turn the valves with something like a screwdriver?

So

Far left - turn 1/4 turn clockwise?
Far Right - turn 1/4 clockwise?
Second from Right - turn 1/2 clockwise?

Please confirm before I undergo this operation

What am I looking for afterwards?

 

[PlumberNot]

shall I cancel the turning of teh valves and undo the loor (flexi-hos ethingy)?

How do I undo it?

 

[kevplumb]

turn the thumb screw thingies

Oakley doakley.

Yes turn off all three, they will at this point only turn one way.

Now observe what happens to the pressure guage

Loop as indicated, Unscrew anti clockwise and pull out, is it constantly flowing?

 

[PlumberNot]

OK

I disconnected the loop and indeed it is dripping water at a constant rate

Do I still need to turn off the 3 valves?

And if so do I leave the loop disconnected or attached?

 

[clf-gas]

WE have now ruled out the DHW HE

OK as I said earlier, You need to replace the filling loop and the PRV.

Bitt of draining down to do but nothing major

Hi

What's the DHW HE?

So... I need to replace PRV and the filling loop

Next step how easy is is to change both things on the boiler and do you think I am capable of doing it?

I need to get a new PRV

and a filling loop - are they push fit or old fashion connecting with olive ring?

I hope to fix these myself and hopefully close on a successful thread.

Any ideas for best place to get these items from?

Finally I would like to thank you all for establishing the diagnosis - you are the A team!
