Thread: standing water in clawfoot tub

  1. #1

    Default standing water in clawfoot tub

    I just replaced the 80 year old drain and overflow assembly on my clawfoot tub. No leaks now but within 30 seconds I have standing water in the tub. Did the old ball joint on the drain create negative pressure that the new T doesn't?

    Any ideas or suggestions appreciated!!!

    Default drain

    Negative pressure would suck the water out of the tub. You have a plugged drain. Although you might have a poorly designed drain fitting.

    It drains eventually. Also, the sink and toilet are downstream on the same line and work fine. I also flushed out the p-trap on the tub before reattaching.

    The tub drained without any issues prior to the new hardware. I did not change anything below the floor, including alignment / slope of pipes.
