    Vent pipe for washer
    Hello again,

    I'm putting a washer where none has existed before (see Washer Height Discharge). You've answered my question about discharging over a door, but now the question about the vent.

    There is no vent stack near the washer. Can I run a 2" PVC vent pipe horizontally? I would have the PVC vent pipe come out of the top of the 2" drain pipe near the ceiling going across the door, and then go down to the floor and out to the exterior wall (parallel to the dryer vent). The vertical drop is 8 feet, and the horizontal run is 10 feet. The whole thing would be sealed. The 2" diameter would seem to allow enough air in to keep the water flowing, whether the air is coming from above the house or the side of the house.

    Thanks again.

    Vent pipe for washer
    Hi Glen, Welcome back. When I advised you about raising your washer discharge line I was under the impression that you were extending the new washer discharge back to the old washer hookup. Since the old washer hookup is trapped and vented you would not need a second vent since all you are doing is extending the washer hose over to the trap. However if you have moved the trap next to the washer hose and then discharging over 5" away from the stack you will need a separate vent. Have you changed the location of the trap in relation to the vent stack? My advice, Tie the new 10' discharge line directly into the old washer stand pipe. That way you will be both trapped and vented per code. Gd luck and keep me informed. Tom

It stinks bad it was not oringinally tied in to my septic syatem but is now

    Hi Glen,

    A washer drain needs all the help it can get. Not installing a vent will put suction on the trap seal, (which you should install at once to prevent sewer gas from entering your house) and slow down the drain action. However you could try it without a vent and if it don't work out install another Studor Vent. Regards, tom
