Just following up with a pic of what I did. My first time working with PEX.

I thought about just cutting the CPVC. Then I would have PB->Copper->CPVC->PEX. That just seems... messy. I think that's a good summary. All my search results basically said to panic and rip out PB as soon as possible, assuming the whole house had PB, so I wanted to get a clearer picture on...

This is what my current setup looks like in the basement: It's a 1996 home which appears to have had the original PB replaced with CPVC, except for this remaining PB at the inlet and some PEX elsewhere for a tankless water heater. My plan is to remove the valves and CPVC in the picture and...

You guys are right. Got rid of the escutcheon and had plenty of room. Thanks.

I didn't really think about just digging into the wall. With my luck, the T connection will be right behind the escutcheon (that's a weird word). But if so I could just cut away the wall and do what needs to be done. Thanks for the idea.

Not enough space between coupling and wall to get glue in a fitting with full insertion. But I could probably get enough to work. I hate doing things half-arsed like that though. I didn't see any obvious posts about removing glue in pipe. How the heck do you remove a solvent welded fitting...

I ripped out an old bathroom sink to replace with new and I found that the previous owner glued the drain line in place and now there's no room to cut it off and add a proper connection so I can position the p-trap correctly. Any ideas on how best to fix this?

So... uh... what can be done? Does that mean the meter is defective? Would a pressure regulator fix it?

I have a loud, constant thumping in the line when water is running. I'm not talking about the bang when the water is turned on or off (I get that too). This is a steady beat of 3 or 4 beats per second and it's faster with higher flow and sounds more like machinery running than banging. The...

Expansion fittings... Doesn't look like I want to mess with those. Guess I'll just use couplers. Copper isn't buried. That's the attic. Those copper lines run down the wall and elbow out to the water softener. Thanks for all the help guys...

Not "running". Just swapping. I.E. the two lines are "A" and "B". So remove both connections and take the PEX that was connected to "A" copper fitting and connect it to "B" copper fitting. I'm assuming I cant just pull the PEX lines off and push them back on.

It could be either the crimp style or the expansion style. I want to just cut the lines off the existing copper fitting and use new crimps to re-install them. Just not sure what type of crimps or sleeves or what to use.

I need to remove two PEX lines and reconnect them to the the copper fittings. I've never worked with PEX before and I'm not sure how to identify what I need. I think there are different types of fittings and I need different type of connectors (crimps?) depending on what I have. FYI: I...
