Hi, I need help identifying some of the components on my main water supply line into my house.
Here's what I know:
#1: 7/8 o.d. copper going into the house
#3: short length of the same
#4: cutoff valve installed in 2018
Here's where I need help identifying the type of fitting (I think all of these were placed in 2018 as part of the cutoff valve installation).
(Closeup photos are shown below first photo).
#2: I need to verify type of fitting please (I think it is made out of metal).
#5: Short metal piece (maybe copper or brass) about 1" o.d. apparently with male thread on left end (into valve). The end on the right goes into #6 which is appx. 1" PVC (coming from water meter).
#6: I need to know about this fitting (see closeup please).
Thanks!

Thank you James. #2 appears that the housing is metal. Is it likely that it contains metal ferrules (which may necessitate cutting the copper tubing to remove) or might it have nylon/plastic compression rings that can just be slipped off to remove?

That valve doesn't look to be in good condition to me.
I don't know what #6 is. Is it plastic?

The housing looks galvanized, but it could be brass, you just unscrew the ends and slip it off. The "ferrules" on those couplings are always neoprene rubber. Because of its age the neoprene is probably shot so you need to go buy another one, preferably with a brass housing. Unless your redoing the whole setup.

I agree with you about the valve. #6 is connected to 1" PVC but I'm trying to find out what kind of fitting #6 is. Thanks.

Thank you James. That's what I was wondering about.
p.s. still trying to find out what kind of fitting #5-6 is if anyone can help

Wow, great help folks.
So, are the following two conclusions correct?

a. The compression coupling should be considered a temporary repair (since the neoprene may be worn out after 3 or 4 years). It should eliminated from the whole setup or be replaced with something else (what)?

b. If I loosen/remove the compression coupling then I can unscrew and remove #3-4 from #5 and unscrew and remove #5 from #6.

They aren't considered temporary. You just can't reuse the seals.

I would ge rid of it for something better. Many options. The best would be install a vault that is accessible and protected from the elements. Flared connections are a common and good solution for these assemblies.

Thanks John. I agree about the accessibility and protection issues. The current setup is far from ideal.

I am a fan of ball valves but not in the ground or other moist location unless the handle is stainless steel, otherwise they will corrode and can break off.

Yes. I am surprised at how bad the valve handle looks after just 3 years or so. Thanks!
