Any rodent problems?

Any rodent problems?

No signs of teeth marks on that section of pipe.

The damaged pipe is the original pipework installed when the house was built. I have patched it twice now but obviously something is amiss.

If you still have the split piece I would send it to the manufacturer and ask them to analyse it to see if they can pin point it

 

[Harvest Fields]

Definitely get the manufacturer involved. You never know they may admit fault!!

Any pictures of the boiler? Could the pressure relief have been capped off or isolated?

It could be a batch of faulty pipe, but I doubt it. Given the consistent way it's failing, it is more likely to be an incorrectly designed/installed system. The expansion vessel might, for example, be on the wrong side of a zone valve so it's isolated when you are just heating the HW tank. Numerous other possibilities. We need to see photos, please. Lots of photos.

Remove sction of pipe and pressurise to 20bar and see what happens. Go higher see what fails

Wet test tho, not air

I'll try and get some pictures added, working 12 hour shifts so haven't had time to do a great deal.

Thanks for all the replys
