    Default Trash can used as sanitary pump crock

    Ran into a sanitary pump yesterday that was installed in a modified trash can (lid was on it ). There was not a check valve / back flow prevent in line with the discharge pipe. The discharge pipe did have a p-trap prior to the connection with the waste drain line. The pump was set up for the clothes washing machine only. Nothing else drained into the trash can. The home was built in 1993. I decided to recommend a crock with a sealed lid and a back flow device. Are there any plumbers out there that would add or enlighten me on something that I might be missing. I am admittedly a little weak in the gray water area.

    Not sure what I should say about this besides ... unconventional and non-conforming drain assembly that is unlikely to be safe or compliant. Remove and have Code compliant drain assembly installed by licensed plumber.
    I've read articles about people out west sending gray water to trash cans/holding tanks etc; running the water through a filtering system; and then running it out into the yard for irrigation water.
    It doesn't look like that is that sort of set-up though.

    It is an improvised sump pit and it probably works ok.
    There is no trap on the washer stand pipe. It is just greywater, but there will always be some dirty greywater in the garbage can, so why not install a trap there?
    You are correct to call for a more heavy-duty crock with a tight lid. Garbage cans are not designed to be full of water, and the plastic will break down and start to leak after a while. It's clever, but it has limitations.
