Galvenized supply to PEX, How to make connection?
 
I removed all of the old galvenized plumbing from my home. I am going to replumb it with PEX. The only issue is that my supply from the meter is galvenized. I don't want to change the supply from the street. It is quite far away.

I have isolated my supply and removed a 90 deg. elbow off of the galvanized supply. How do I connect PEX to the galvenized supply? I need to install a shut off valve there also. I bought a PEX shut off valve but it has PEX connections on either side. Please let me know the best way to go from Galvenized to PEX. Thanks.

Install a threaded ball valve on the galv. pipe. On the other side of the valve install a trread to PEX fitting (male thread to PEX barb). I would assume since this is from the meter it is at least 3/4".

You should be able to get an IPT to PEX fitting. Just get a shutoff valve with two female ends and get the Male pipe thread to PEX connector. I have this setup in my house for an outside hose hookup. I'll try to get a picture in a little while and post for you. (Sorry for the repeat, I typed too slow)

I would never use a pex valve for a main.
Get some brass fittings the size of the galvanized pipe (3/4 or 1"). Do not cheap out and get galvanized fittings. Get a brass elbow onto the galvanized pipe comming out of the foundation. Now use a short brass nipple. Now put a brass IPS ball valve after that. Then put another brass nipple about the leangth of the ball valves handle. Now get a brass tee 1"x1"x1/2" or 3/4"x3/4"X3/4". Install a boiler drain into the side of the tee. This will let you drain all your water lines easially for future work. You can now put an IPS by pex adapter in the other side of the tee. If they don't make that use a copper male adapter, a short piece of copper, and a sweat by pex adapter.

Whether you decide to use a PEX valve or a brass valve, what you will need to do is use a threaded adapter to barb fitting to transition to the PEX.

I would recommend replacing your water service if at all possible. You can use polyethylene pipe, which is PEX without the crosslinking. This comes in 300' rolls and is under .50 per foot. You would need to check your local code but it is approved as a water service piping under most codes. The reason I recommend replacing the service is because it is as old as the pipe you are replacing and probably has the same problems. Leaving the galvanized service means you are running the risk of having rust and corrosion get into your brand new piping and screwing it up. It is generally better to start supply piping replacements at the upstream end of the system. This will help ensure that you will get the full benefit af all of the hard work you are doing.
