As part of our renovation, the builders ran new radiator pipes through a chase in the solid floor and then filled it with pea gravel and concrete. The photo was taken before it was covered. There are several push-fit tees in the run, and they’re now buried. The building work is almost complete (finished floor is down, painting is underway).
Pipe is Polypipe - it's a sealed system with a combi boiler. I'm told an air pressure test was carried out before covering.
I understand this isn't best practice, and I'm not looking to start a regs argument. I'd like to know:
* How common is this in real-world domestic work?
* In your experience, how likely are buried push-fit joints like these to leak over, say, 10 to 20 years?
* Short of digging it up, is there anything worth doing now to reduce the risk?
