Plumbing question with picture

[Lucas156]

I have copper pipe coming into the house with a plastic valve attached via polybutylene pipe. If I put PEX pipe onto this copper pipe to install a ball valve instead-would PEX pipe work in this case? In other words-is the barbed copper pipe coming in suitable to PEX as well? I have replaced a lot of the pipe in the house so far and this is the main shutoff valve in the house-it's old and needs replaced-leaks in the shutoff position and doesn't get the water all the way shut off.

No.

One should not even mix different makes of PEX tubing and fittings. The idea of attempting a proper fit of a copper crimp ring on a barbed copper fitting with Brand-X PEX tubing in between is insanity.

Yuck. When I want plumbing I get out the blowtorch, but I grew up with copper. I had a main valve like that; replaced it with a ball valve. Well worth the price.

In my universe, there are no valves but 1/4-turn ball valves and proportioning valves. All else is heresy and treason.

Temperature-tripped and pressure-tripped emergency relief valves get a pass, though.

Get the proper fittings or you'll regret it (ask me how I know). You can copper to pex but see the first sentence in this post.

My long lost valve sister!

Lots of sand paper.....clean copper.....proper fittings also sanded clean.....proper solder...proper flux...propane or map gas torch. Have at it.
Do a ball vale and forget it.

What would I do after soldering in the ball valve-I have to connect to the polybutylene pipe at some point unless I want to replace a very long line

I am also a member of the "Brotherhood of the 1/4 Turn Ball Valve".
At one time they were making cute little ball valves to use at sink faucets and toilets but I haven't seent those for a while.

You can do it without soldering, just get the right fittings. Cleanliness of the copper is critical whether using slip fit or solder. I got my stuff at Menards. I cut in a whole house filter and a water softener using predominantly the compression style pex fittings but did use a couple of the slip fit style to transition. Been there for two years now without a single leak and that 1/4 turn ball valve beats the crap out of that cheap **** they install when they build houses.

This ^^^^^^^^^

The slip fit are more expensive but much more user friendly when fixing wet pipes.
Clean and debur your pipe before fitting together or you can gouge your o-ring.
They are also nice as they have the ability to be taken apart easily if you ever need to.

I laughed way to hard when I read this... My mind is in the gutter today.

Some lube may help in this area. If you gouge an o-ring you'll hear about it.

Well this thread went weird quick, fast, and in a hurry.

Plumbing threads seem to have a habit of getting weird.

Sad thing is I didn't understand a word of it until it got weird... does that make me a bad person?
