Interesting concept. I’m glad to be aware of that option. However, I have very low confidence of any fitting that attaches to PEX. So I would still want the joint of the fitting relatively unburied as well. One side of the valve is galvanized pipe. I suppose I could replace the PEX with steel as well and then join the PEX to the steel under the showerpan. I’ll have to keep that in mind.
@Damage I’m tempted to get a valve with a replaceable cartridge even though I hope to make the fitting accessible anyway— just because it seems like a smarter design.
What do you call that kind of valve?
I tried an image search for “water valve with replaceable cartridge” & most hits were taps & shower mixers. A local shop had one that looked kind of like this. The lower portion was simpler, but the handle is the same. My concern is that the handle is designed for a human hand and I would actually be running a steel rod to the handle so I can control it from an adjacent room. Most valves seem to have a removable handle so you can easily attach a tool to it.
I would like to find one that has a removable handle and a removable cartridge for full versatility.
