    Shower Slow to Drain

    We took our brand new 22mle out for the first time a week ago and things went well. I noticed the shower pan starts to fill with water pretty easily, that's with me turning the shower head off and on as needed and a shower that lasts maybe 7 minutes.
    Once the pan empties there is still sitting water down the drain which seems to stay indefinitely as it was still there the next day.
    Is this typical?

    Is this the only drain that is slow?

    It is the only one to drain slow.

    It's brand new, that was the first shower. I suppose they could have built it ****** backwards and got crud down it.

    What you are describing is a full holding tank. Are you sure the tank is not full? Dump the shower tank and see if you still have the problem.

    By "shower tank" I assume you meant the grey tank? It was emptied when we left, noticed water had spilled in the bathroom and since we didn't have water the last day it wasn't from us. That's when I noticed water down the drain.

    To be fair I haven't taken the cover off under the pan area, my thought was maybe it's a p-trap and it's holding a touch of water.

    ​I know you said the tank was drained but did you use a clear elbow to confirm water drained out.. we had a gray tank that had the debri from drilling the drain hole block things up and would not drain on one of our first few outings . This still happens on rare occasions.
    We always use an external clear back flush elbow when we dump (like the flush king) to beat it back in when it happens...knock on wood it hasn't in a long time .

    Excellent question. Prior to taking it out I filled each tank with clean water and then pulled the drain valves. Just wanted to make sure all was working. I do also use a clear elbow when draining actual grey water and everything flowed on all tests.
    We go out again this weekend so I'll maybe poke around a bit more and take a look under.

    Have you tried checking the drain for an obstruction yet? I got this https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1 from Amazon for hair in the drain, but it will surely work of anything else stuck in there. It'll at least tell you if there is something there.
