Prv pipework routing

[stratplus]

Went to a property yesterday for an unrelated job but had a look at a new Worcester boiler install done a couple of weeks ago. The boiler was installed in the a/c in the middle of a standard 3 bed mid terraced house. The prv pipework came out of the boiler then elbowed up into the loft for approx. 2metres where I assume it was taken out either into an internal soil or through the soffit, I didn't look into it.
My question is does anyone else take this pipe vertically from the boiler? I always thought this pipe should have a fall away from the boiler and never seen one like this before.
Looked through mi's and nothing is mentioned.
This install was a boiler swop so he's done it to save lifting boards.

Up???

Up???

Yes off bottom of boiler and up into loft. Sealed system so once it blows off water can only go to wherever it terminates but surely this pipe should fall not go up

I should have taken a pic to post

Condense was pumped

Why didn't they dump prv in to conny or use a remote?

Customer said they had problems with water noise when they slept so installer came back and fitted the condense pump after the install. Sure they mentioned condense went to loft originally but surely the trap would have overflowed into boiler although looking through manual dosent the worcester have a sealed sump?

Would the pumped condense cope should the prv blow?

not all pumps are rated for prv

Prv pie should always fall. What if it discharges, water freezes in it, it tries to discharge again and the boiler blows up.

 

[Ermintrude]

Yes but if you know u need one that does. That is 99.15% of occasions when you need a Conny pump u need to move prv discharge?

Only time when I use conny and don't use it for prv is when it's a heat only. I run my conny pump outlet through a 21.5mm without glued joints as it looks a lot better!

It clearly says it in section 3.5 page 14.

 

[Ermintrude]

Won't load what doth it say?

 

[albatross]

It says it must run downwards.

Didnt look in pre-installation, just installation so didnt see that.
Can't understand why experienced installers do these faults??

 

[Ermintrude]

Because it's easy!!!!

Dont they leak without solvent

 

[Ermintrude]

The 21.5 is just a conduit to protect the conny hose from damage.

Because they are cowboys.

Shocking :thumbdown:

 

[AWheating]

experienced dont always equal good. i have known installers that have been at it for 35 plus years that were terrible, even dangerous. was even worse when it was the acops and any one with half a brain cell could pass. (you now need 2 to 3 brain cells LOL)

vaillant is the only manufacturer I know who do remote prv kit Worcester do not

 

[ADM360]

just to play "devils advocate"

may be he took the time to "knock" out the prv in the boiler and remote sited one at high level to allow a fall from the prv.

Just saying Maybe!!
