Forum Title: a bit of rust
I recently put in a new shower valve and now have a peculiar problem. When I turn on the hot water I get just a few seconds of lightly rusty water. Only the hot thought. The copper comes through the slab and an iron pipe. I suppose the iron pipe just protects the copper where is penetrates the slab. I fear that during installation I might have stressed the copper and now there is a breach between the two, allowing that bit of rust to come through. Thoughts.

Can you explain more on The copper comes through the slab and an iron pipe Is the copper connected to the iron pipe and water passes through the iron pipe. that will give you rust in the water. OR does the copper some how run through a section of iron pipe like a sleeve? is all the piping to valve copper and is it soldered into valve or was there any threaded nipples/fittings involved?

I had a new gas unit put in about a month before, no rust. It's only at the shower that I see rust at. That started happening soon after I replaced the shower valve.

How is your hot water heated?
