If I replace the galvanized pipe from the meter onward, is it OK to just tie the ground to the Pex and leave everything else as is?

I assume that as long as the ground is attached to the main pipe into the house I should be OK - correct?
Ground wire has to be to conductive metal, quite sure. Your basement reminds me of mine.

I finished my plumbing install. It went pretty well. Pex is incredibly easy to work with. I removed all the galvanized pipe from the meter onward. I extended the 3/4" copper pipe to within about 6 ft. of the meter, and used Pex to connect the meter and the copper pipe. I would have used copper to the meter, but it would have been difficult to install it so close to the electrical box. Too many wires in the way to use a torch safely.

I now have a 6 ft. Pex run between my pipe into the house (galvanized) and the copper that runs through most of the house. I noticed that I have a few upstream grounds in place for the phone line and my boiler. I need to replace that since the Pex now interrupts the ground.

Can I get a few clamps and run a wire from the copper section of the plumbing to the galvanized section? Is that a sufficient ground to replace the one I lost when I remove the old galvanized pipe? What sized wire would be acceptable?

Want you all to know that I just read all of your conversations and found them to be very enlightening. I would like to ask a question... had a new roof installed 4 mos. ago and a leak in a 1st floor ceiling (back hall) immeditately started. after dealing with the very hard to reach roofer via the process of elimination (stack pipe-not, cheek wall/missing soffit piece-not), he concluded yesterday that the leak is coming from a pipe on the floor in the upstairs (2 fl home) attic/crawl space and that I now should call a plumber. Would anyone know what kind of pipes would be in this area of a house? A friend said possibly heating system?? A very good source on this site said probably water (from roof pipes to sewer)?? The house is old (1930s) so I assume it's galvanized piping-for what that's worth. Also, are there different types of plumbers who work on different types of pipes (water, heating system)? Sorry for my ignorance but thanks for any kind of info.

I ended up running #6 solid copper from the copper pipe to the galvanized pipe using 2 grounding clamps.

I thought so. The attic is filled with blown in insullation but guess I'll have to do it. I spent a lot of time on YouTube trying to figure this out but - no luck. Does it mean anything that the leaking pipe is the same size as the pipe coming from a radiator in a room and going into the floor? Wondering if that means it is part of the heating system??? I really admire and thank all of you who know about all this stuff. Thx

All the plumbers I've used will handle any water/gas pipe work. It sounds like this is probably a heating pipe. although, I can't imagine why anyone would run a water line into an unheated attic in the North East.

Re: Replacing Galvinized Pipes


Hi: My one story 2 bath home with Laundry room and water heater in the same area needs new pipes. I have galvanized and house is 43 years old. Before I have the ceilings coming down, I would like to know how I go and hire a good re-piping company. And what I need to look for.
Thanks for your help in advance.
