I have been looking at articles and videos on Pex A or Pex B for my bathroom reno.
It seems the general consensus that I have seen is using Pex A.
More flexible and less flow restriction.
Watching some of the tutorials on using the expansion tool and fitting install got me wondering.
If Pex A is this flexible/pliable it looks to me like hot and cold could affect this connection.
Being a DIY'er and not in the trade per say, it just looks concerning to me that there is no positive locking of these connections. Just expansion and contraction of the polyethylene material.
If I take a really hot shower, what keeps the Pex A from expanding around the fitting and leaking?
Another instance that happened that brought this thought in my head was,
I bought a new camper. It has Pex B with the metal crimps on the fittings.
The dealership said to check these fittings after 6 months and a year. Sure enough, right at the water heater I had a fitting leaking. So I put a hose clamp on it and so far so good.
I know its not the same as the Pex A concern, but leaks are leaks and it just got me thinging.
