Pressure relief valve

[mickeyuk]

Hallo just after some advice and your thoughts on this one. Yesterday went to service a condensing combi and i have to say it was a very good installation in a flat above a shop . However they have run the prv pipe into the internal vent stack just above the condensate pipe is this a no no or is it ok .It would be a nightmare to change and run external with the shop front windows and doors etc .What do you think ?

its not allowed, ive seen a few discharge into 1.5" waste under kitchen sinks

Thanks mike would you say this was a safety issue and if it is why ?

 

[Barry98]

yes , you need to be able to see when it discharges

Thanks Bod although i personally would think it would be safer to discharge the boiler contents internally rather than outside and after all you would be looking at the pressure gauge to tell you its discharged

If you can't change it put a tundish in

Hi Gray so the regs state it has to be a visible discharge thanks !!

What I'm saying is if you can't change it put a tundish in so
It's visible but it's still not right
