Why do I get rusty water from only the tub when turned on? All new plumbing (PEX), water heater, Delta tub and shower fixtures.

Hi Bakerwr

If you only get rusty water from your tub/shower valve then someone has probably left a black iron test nipple (rusts) in place when it should have been removed and replaced with a brass nipple (doesn't rust).

Call the plumbers back and have them check the tub spout nipple... my guess is that is the issue... ;)

Thanks Was a galvanized nipple. I replaced it with brass and problem solved. Thanks again.
