prv discharge pipe

[plumbdoctor]

been to quote a job today and its going to be a right mere to run the prv pipe to outside can you discharge it internally into a soil stack if you have a tundish ?

 

[bennygas]

i have seen it done to a little tank with a lid in the bottom of the airing cupboard - done by a big firm, and apparently they reckoned they had approval to do this. anyone else come across this?

what do the manufacturers instructions say?

 

[AWheating]

its possible. Its done in alot of flats and basement installations. You may require building control permission.

 

[SimonJohns]

I know it can be done on uvhws. But for a boiler I'm sure you have to go outside

have worked on site a block of flats where each flat had a worcester gs 24 junior combi and everyone had tundish then into hepvo trap then onto soil stack , all passed by build control.

or you could try these Condensate Pumps: NXT Gen: VCMA

 

[andyg0507]

sorry i think ive just totally misread the op, i was thinking condensate, worth a look for condensate stuff tho.

 

[AWheating]

you can get a combined condense blow off pump but they cost around 180 squids.

 

[andyg0507]

have you got a link to that??

personally would rather find another way instead of possibly pricing myself out with an extra £180

 

[andyg0507]

and how does the condensate combine with the blow off, with condensate being acidic, i.e what type of pipe is it run through?

 

[AWheating]

there a few about. Baxi have even got there own branded one on the market now also.

one copper pipe into pump, one plastic im guessing.

condensate requires non metallic, blow off requires pipe capable of taking high temp, so its just about choosing the right type of plastic to suit the blow off temp

seen a condense pump advertised to take condense and prv but i am not convinced its correct.

some boiler manufacturers do a remote prv kit.

 

[Kev the gas]

any links to that said boiler manufacturer please ?

 

[arran197]

I think a lot of the condense pumps will now take the prv too. You may have to contact the manufacturer, but some will allow a remote prv providing the prv on the boiler is correctly dealt with. That's either by using their kit they supply or repiping it in to the system. You can't just plug/cap it off.

Worcester allow this I argued with my manager about it until he showed me it in writing from manufacturer that we had sent direct from worcester. It has to be suitable for the temperatures so F+E tank with lid and an air gap.

They use f and e cisterns for solar prv's. Stops the glycol from entering the water table
