Standpipe Plumbing Laundry
Laundry room plumbing
Hoses, valves and one standpipe. They live behind a machine nobody moves.

Jobs in the laundry
Washer hoses and valves
Rubber hoses split with age. We replace them with braided lines and test both valves, because a valve nobody has turned in years often will not turn. The full page
Washer drain backing up the standpipe
The vertical pipe behind the washer is the standpipe. When it overflows, the clog is below it. We clear it and check the box on the wall. The full page
Wet wall behind the machine
A damp wall or a soft floor behind the washer usually means a valve or a box leaking slowly. We trace it before we open anything. The full page

Questions
Short answers
How often should washer hoses be replaced?
Many people change them every five years or so. A hose that is bulging, or crusty at the nut, is worth changing now.
Why does my laundry drain smell?
A dry trap or a partial clog in the standpipe. A person has to look.
