Common Waste Pipe for PRV Discharge

[dieselracer13]

Where is the condensate going? And why is the installer not having a say in the matter?

Condensate will be pumped to soil stack on the other side of the house.

There is a pump that will do both the condensate and a PRV but don't believe it will do all three PRV's.

Call me old school but for me

PRV should be unrestricted, what happens if the pump fails ?

I agree and the same applies for condensate but sometimes needs must.

Hi all just picking up on an old thread.

On the same theme, I am isntalling a water heater which has a pressure relief valve (pressure only, not temperature as not required) which only deals with back expansion in the system so only ever would let out tiny amounts of cold tap water (or lots if the prv failed I guess, but pretty unlikely).

Does anyone know if it is permissible to discharge this into a rainwater stack instead of the soil stack? The only way I can connect to the soil stack gives me a rough connection that is more likely to leak so I'd rather avoid it.

Thanks
