I want to buy a wireless door/window alarm,Can anyone recommend which one is better for the elderly and children?
I hope you mean galvanized steel pipe, not corrugated steel pipe. Black iron pipe is used for natural gas or propane. It is OK to use galvanized steel fittings for gas, but black iron fittings are preferred. For water, only use galvanized steel pipe and galvanized fittings because black iron fittings will soon rust. Galvanization slows down the rusting process, but eventually all steel pipe will rust. I would only use copper pipe for new water plumbing.
You really shouldnt. I believe its against code.
Get the Pvc replacements for all pipes and make sure they are the same size. Turn off the water, remove the pipes and take them to Lowe's and ask for the same in PVC. Take a towel under there, dont forget.
