A quick question - must the PRV on a sealed CH system be vented outside? I would've thought so, however the surveyor made no mention of it on a friend's survey (a full Building Survey I believe) so either he missed it or is not obliged to check such things?
As it currently stands the PRV would empty onto the kitchen floor in an over-pressure condition.

Yes.
I would not expect a surveyor to know this, although some might.
You need to get that fixed. In a worse case failure condition, that might be ejecting 40kW of steam, and that could seriously injure or even kill someone in the kitchen.
The message from snipped-for-privacy@cucumber.demon.co.uk (Andrew Gabriel) contains these words:
I wouldn't expect a surveyor to know £$%* all.
Although this is an extremely unlikely condition, ISTR that one of the crimes a house-of-horrors punter did was exactly this. The person in question is currently banned from working on gas by the HSE.
Thought as much - thanks for the clarification. Just wanted to check if this was something that needed raising with them.
Sure - will sort it for 'em tomorrow.
