Is the PRV of my worcester 28i greenstar junoir ok

[adp]

The pipe outlet on the external wall seems so short and there is even a cap on the top. I am not sure whether it is normal for this particular type of boiler.

Also any one tell me how to drain the boiler properly if necessary. Is the plastic part with a cap on the left side used for draining (the photo is overturned) or the other metal part which connect to filling loop (the photo should turn 90 oc clockwise)?

the prv terminal is fine, its a mushroom type fitting which is design for this use.

to drain the boiler put a hose on a drain off cock and let the water out.

mushroom fitting a. never heard of one of those. are they expensive and this is why i don't see them

 

[AWheating]

about £3-4.00 roughly, there ok. mainly found on new builds.

 

[mutley racers]

oh ok, nice. gives a neat finish. cheers AW

They look neater but cost wise compared to 2 elbows its not worth the expense.

Buy a ideal logic + and there's a similar one in there as well.

didnt think you needed a auto bypass on the worcester

 

[Billy Bob Bob]

use these all the time paying £2:60 for them

 

[plumber0808]

If its fully trv'd the ones on the boilers don't let a lot through.

new spec for zoning requires a bypass to be fitted aswell even though the boiler has one.

 

[mutley racers]

I would buy these if I could get them that price. Its a much neater finish and after all, it is the client that pays

and less likely to get stolen for scrap. seen loads of house with the pipe coming out of the wall sheared off where the double elbow used to be.

Thank you and everyone very much.
very glad to know the terminal is ok. I actually assume that someone blocked the pipe with a cap:teeth_smile:
Could you tell me which one is the drain off cock? The one connect to the filling loop or the one next to the condense pipe?

There's one just inside the boiler casing but the easiest one to use is the one on the bottom of the spirovent (big brass thing).

As far as I know, Worcesters don't have integral bypasses, I always fit one externally on these.

Thanks. Do you mean this one which connets to the filling loop?


I attached another picture. I would like to know what is this part used for? The one has a grey plastic cap on left side. Thank you
