Sump pit in basement receives washer water and really stinks!
Our washer is in the basement and drains to an open sump pit (submersible pump), which, after it fills to a certain level, will turn on pump out the gray water. The pit has been really stinking the last year or so. We flush it out occasionally which helps for a while, but the smell always comes back. Can it be plumbed directly out instead of going to our sump pit first? We have a high efficiency washer, so it sometimes takes several loads to get the pump to kick on and push it out. We had one plumber come in but all he did was clean out the pit and replace a backflow valve that was broken. That did not seem to help the problem for very long.

The pit has a cover, but is not sealed. The washer drains 10ft horiz. To pit then the pump pumps it up, over, and into kitchen sewer line (8-9ft) up. Can washer pump alone push it that far?our softener and furnace also drain to sump pit.what is AAV
