Plumbing: Looking for advice with water service fix?

The valve farthest right is leaking. Below that is heavily corroded galv that goes into the ground. Moving right, the first tee feeds into a sprinkler system which is the PVC you see in the lower-right of the corner. I want to leave that stuff intact because it’s working fine and it would be a huge hassle to mess with.

Moving right again, I guess that’s a pressure regulator? No idea what the ball valve is doing there, I guess just another shutoff option. Then it goes into PVC and back into galv into the house.

I partially exposed the corroded buried galv going into the first valve, and it’s horrible. Super corroded, must be original from 1956. Got about 2′ exposed before I ran out of time. The valve and exposed pipe is leaking pretty good, 2-3 drips per second now.

I want to replace the corroded galv and leaking valve, but I also want to do everything else as correct as possible.

Questions:

  1. What do I replace the galv with? I guess UPC states I can put almost anything underground. Thinking either poly or PVC, then backfilled with sand. Open to input.
  2. Do I need a pressure regulator at all?
  3. Any other recommendations for cleaning this up and doing it as properly as possible?

Thanks.

Answer: Check code to see what see if they allow PVC or Pex  for underground water supply. I personally like copper, use rolled soft copper or PEX for the water service from the water meter to the house, with those products you will have no connections underground. The ball valve was probably installed because the gate valve for the water service was bad.

The pressure regulator is there for a reason so make sure you reinstall it.

As far as cleaning up that mess, I would run the new water service straight up to the house service. Between the ground and the service install a ball valve, after that install the regulator, tee off for the sprinkler and tie into the house service. You should be able to install the regulator vertically. Get the model number and call the manufacturer to make sure. Also if you use copper you will need a di-electric union to isolate the copper from the Galvanized pipe to prevent electrolysis. Pex will be the easiest to install if it is allowed in your area
