Draining washing machine into sump pump?

Hi All,

I'm thinking of moving my washer/drier into my cellar, which has a sump pump. Is there any reason not to have the washer drain into the sump pump hole?

Otherwise the hookup would be on the ground floor (one floor up) but I don't know if there's enough pressure in the washer to drain upwards to there. What do you think would be the better option?

Thanks for the help!

Steve

Long ago that would have been OK but most modern codes do not allow gray water discharge onto the ground. So, check with your local building inspections department.

Basically... your sump pump probably dumps out on to the ground outside your home which is OK for groundwater. It is no longer permitted in many areas to simply discharge household gray water (sinks, tubs & showers, dishwasher, washing machine...) onto the ground. That waste in many areas must discharge into a sanitary sewer or septic system.

You can get an inexpensive utility sink pump that attaches right to the sink drain that'll pump the grey water upstairs to your sewer connection.

Washing machine pumps are pretty strong. It can probably push it up one floor.

I admit it. My wash water goes to a 50' hose which is used to water a tree. No diapers in this house, and sandy soil, so no problems.
