Prv & condensate pump

[GrahamM]

Thoughts on this set up guys.

A load of these installs have appeared on my patch.
Prv ran into condensate pump via tundish and plastic pipework.
The condensate pump is compatible as per Saermann.
Vokera were giving no specific answer saying refer to British Standards.

pump isnt suitable for high temps, though you can get ones that are.

They've recently altered the regs on this. You need to check with the manufacturer. It can go in to the pump, but in most cases the prv water shouldn't go in to that type of pipe. It needs to be rated for high temp, but the way to get around it is to put the prv in copper and go straight in to the pump rather than via the overflow pipe.

I'd be more worried that the outlet hose from that pump is kinked & will kill the pump sooner or later!

The PRV pump is probably 5 times the money... Maybe it's overkill for a problem that would never really exist... The existing pump would probably cope if the PRV started to open, they only seem to drip or run slowly, unless a fill loop is left connected & on but that's just unlikely.

I would just highlight it to the customer so there informed & Ncs if you want to cover yourself?

Seeing a lot of installs like this myself of late , i just tell the cust and i end up doing it properly .

I do love carp plumbers keeps me busy

from what i have seen from the prv/condy twin pumps,there is a flowswitch wired in after the fill valve that shuts off if the pressure goes over a certain point,for example if left on,not fitted any yet though

Pipe the prv into the return and fit a remote prv on rad pipework on an outside wall big problem solved.
