When I first arrived on site I thought that I was dealing with PB, that was not the case as the pipe is clearly marked PEX (Cross-Linked Polythene) In any case, it would seem that MANABLOC - PEX is the answer and remedy to PB piping, it is rated 100 PSI @ 180 Deg F. This particular installation was 9 years old operating flawlessly without leaking.

This is what I say:
Subject home has cross linked polyethylene (PEX) supply pipes. This pipe has replaced the controversial Polybutylene (PB) piping which is a plastic supply piping system with a history of premature leakage and has lost judgements in class action lawsuits. PEX piping has been used in Europe for years without problems but is too new in the USA to have conclusive data. It is the current standard in plastic supply systems.

David,
Just wondering why you would mention Polybutylene at all when discussing Pex. PB and Pex are different products. If the subject were say... wiring, would you write something like;
Quote:
Subject home has non-metallic two conductor copper wire commonly known as Romex. This wiring has replaced the controversial knob and tube wire which is a older single conductor wire system with a history of causing fires. Romex wiring has been used for years without problems. It is the current standard in electrical wire systems.
The words the client will most focus on is "causing fires"
Pex may end up not being any better in the long run but until sufficient data has proven this I don't think we can take an alarmist view. I think a client reading your narrative 5 min later will remember only something like "plumbing - bad". Remember clients are reading (actually skimming) through your report to find out all the bad things.
Please don't think I am attacking your narrative. Its just kind of something that struck me as I read it and I am curious as why you included PB with a Pex narrative.

Possibly because PB was the ‘next best thing’ and proved to be failure prone in many instances, and PEX is the ‘next best thing replacing the last best thing’, but do we really know how long it will last here? No, so advising your client that they have a relatively new to this market product is the prudent thing to do. You told your client that it is a new thing, replacing a ‘bad’ new thing, and that there is no enough history here to know how PEX will perform here.
Like seeing a 200 year old house and telling your client 'Well, this is certainly not the way we build houses nowadays, however, after 200 years of sustaining the current climatic conditions, it has passed the test of time, and we can only hope that newer houses will also be around long enough to pass the test of time.' You just told you client that it is not built to today's anything, and that might not be a bad thing.

I guy I fight fires with put a pex system in his home… he said it was the slickest thing he’s ever used before. He installed it himself. With the manifold system and flexibility it’s really revolutionizing plumbing water supply in homes.
