I have a bath tub in my upstairs bathroom that does not drain properly. Due to the way the batroom was built it is impossible to get the proper pitch for the water to drain out fast enough. Is there a pipe fan that can be installed in the overflow pipe to increase the flow or any other suggestions will be appreciated.
Thanks, Jim [email protected]

How old is the house? Have you confirmed that there is proper ventilation in the bathroom?

My question is this. How do you know this? Pleaser explain. Cheers, Tom
