Temporary PEX lines? And what connector type is best long term?

How hard is it to disconnect PEX connections once they've been made?

I ask because I think I'm going to need to set up some temporary re-routing of a few water lines so I can reconfigure some other elements (electrical, ducting, stairs, etc) before I set up my permanent configuration.

Also, long term, can I trust sharkbite connectors? Or should I go full out crimp styles?

Hi,

To disconnect crimped pex I just cut close to the fitting. Un sweat the old fitting, and sweat on a new.

I dont trust sharkbites at all. I have seen too many leaks. They have thier place but I would not usethem for a permenent application.

Go full crimp...

What about temporary pex-pex fittings? Like this?


How hard would removing the crimp be on something like this (or more likely on a T meant to be temporary)?

I probably would not use plastic but its up to you.

In order to remove a pex connection you need to cut the ring off. Often the pex under the ring gets cut. So you need to cut the end anyway so its clean and smooth for the new connection.

If the plastic is alot cheaper and you have many temp connections then go for it.

There is a PEX removal tool. It looks a bit like a pair of pliers or wire cutters. You cut the tubing close to the fitting. Then you insert the rounded end of the remover into the fitting and the squeeze. The cutter on the outside cuts the crimped ring. Then you use the tool on the other side in a few places but not applying full cutting force but just squeezing to open the ring up. It takes about 15 seconds to remove a connection and the brass fitting is undamaged so you can reuse it.
