Expert Laundry Standpipe Plumbing in St. Louis
Is your washing machine overflowing or producing foul odors? The issue may be stemming from your laundry standpipe. At Maplewood Plumbing and Sewer, we specialize in repairing, replacing, and installing laundry room standpipes to keep your plumbing system functioning how it should.
The Importance of Laundry Standpipes
A laundry standpipe is a vertical pipe that connects your washing machine’s drain hose to your home’s waste stack. Although it might seem convenient to hook up your washer to any nearby drain line, this shortcut often results in water overflows and worse—could introduce toxic sewer gases into your living space.
For your washing machine to drain correctly, your laundry standpipe setup must include these three critical elements:
Standpipe
Standpipes should be at least 2” in diameter to accommodate your washing machine’s drain hose. Older residential codes allowed for 1 ½” standpipes, but modern washing machines require a larger size. Your laundry standpipe must extend past your washer’s overflow line, typically reaching a height of 30-36” or 18”-30” above the trap.
P-trap
A P-trap prevents hazardous and potentially flammable sewer gases from entering your home. Any fixture connected to a waste line must have a P-trap installed. The trap should be located 6-18” from the floor, and it’s crucial to maintain the correct pitch in the horizontal pipe connecting the trap to the waste stack.
Vent
Unvented pipes are at a high risk of overflowing and releasing harmful gases. For laundry standpipes, the vent should be at least 1 ½” in diameter and located within 5 feet of the trap.
