Gray Water Discharge Question

Is this a good idea? its not a sump crock its just a well collecting gray water from the wash basin then discharging it up to the drain which appears to be connected correctly, with the loop on top. The sump pump is at another location in the basement. The only thing that I don’t like is the fact that one day the pump will go out and water could be all over the floor if using the wash basin,( soaking clothes with a large tube of water then opening the drain plug and walking away). Should I recommend this be contained like a Sewage Ejector Pump would be? Or it is what it is. This is actually where I live, we are renting and I am not sure what to say in the report if anything. So you can see my concerns both ways. The only info I have found is that it is not common practice to use a sump hole to eject gray water like from a wash machine or sewage water. Thanks!

Sump Pump Discharge Location

Where is the sump pump discharging? Into the city sewer?

Sump Pump Discharge Details

The sump pump is discharging through the wall to the out side of the home above ground. It never turns on because we have sandy soil in this area.

Inspection Advice

If found on an inspection I would advise client of the potential for the senerio you have described with a overflow. A sealed container woul be best resolution (called laundry tray pump in my area). Would also recommend a cover for the pit as it is a tripping hazard without a cover.

Also from the photo although probably an optical illusion it appears that they tee wye fitting is turned the wrong way (wye toward upslope of pipe)?

Additionally I would recommend that the sump pump discharge point is directed away from the foundation wall. While inspecting we can’t know how often water is ejected from the pit. So it’s best to recommend that it be directed away from the foundation wall.

Also what’s the piece of PVC running across the top of the pit and the wire running across the floor? It looks like the power cord for the pump runs up the discharge pipe?

Soapy Water Discharge

Soapy water is actually fine to discharge outside right on the ground but most plumbing inspectors don’t see it that way.
