Hi, sorry I was responding to the other quotes when I saw this.
There isn't anything to separate, I've put some pictures below:

The PRV is inside the boiler casing, this confirms it - https://theintergasshop.co.uk/inter...ergas-rapid-pressure-relief-valve-844097.html
How are you supposed to know when it is passing, if it is built in and discharges with the condensate?
Oh wow really, I'm not sure I'd get my shoulders in there let alone my backside!
That's interesting, I've got a UV torch for finding golf balls on the course behind our house
. Don't know if it's powerful enough (it's this one).The pipes aren't in concrete, would the significance of the leak help at all?
I'm OK in tight spaces, not claustrophobic or anything but may well get stuck against pipes or something not knowing what I'm doing. I really doubt I'll get myself under there anyway! I may also be overestimating the height of the crawl space, I'll try and get some footage I took from the inspection camera.

Sorry was that a question for me as I'm not sure how you'd distinguish between the PRV and condensate water.
You don't need your shoulders or backside to go in, you lay flat, face down and shuffle along
That torch should be fine.
The heat camera won't work under floor boards, as it won't be able to pickup the heat signature sufficiently. The experts you spoke to should have advised this. Even with a significant leak, unless the leak is in a wall, but I would imagine a leak in the wall would be pretty evident.

No, it wasn't really a question - I'm just puzzled by a design of boiler which makes it so difficult to find out if the PRV is leaking or not.
All combi boilers PRV is on the inside of the boiler casing, some have combined condensate and PRV outlet but if this is the case there is a visual indicator that tells you that the PRV has operated
open the two valves that you mention, that isolate the up and downstairs , check the boiler system pressure, put the heating on and half an hour later check the pressure again, and come back and tell us the 2 readings
Don't know why we are still persevering with the idea of the PRV leaking, because I think we have established it is the leak under the floor, but would the visual indicator allow you to spot if the PRV were just passing?
yes that is why it is called a visual indicator, and how have we established it is a leak under the floor ?
you say a little water how much is a little ?
De pressurize the boiler. Whip the bleed vent out of the top. Pour a big scoop of drain tracing dye in. Bleed vent back in and top it up and bleed. Run boiler look for coloured water inside and outside the boiler and under the floor.
Doesn't matter what colour drain dye used.

Surely backside will have to go in at some point
Here's a brief video from the inspection camera.
The experts I spoke to didn't really mention the thermal imaging, only as one possible method of operation, they were mainly talking about draining the system and inserting a gas. Presumably the leak isn't in a wall or even near a wall because there's no signs of dampness anywhere...
Ahh right, with you.
Do you mean close the valves to isolate the downstairs heating pipes?
Do you mean from the bucket? It's hard to say in a measurement but around 30ml?
Would this work without being able to see under the floor? Presumably that's how I could get the UV dye in there?
