    When a tub drain has no vent
    We know there's no vent for the tub/shower drain. :( It has always been a slow drain. Now, after a short shower, water will seep from under the tub and from under the toilet. When we have plunged the drain, sand comes up. How can we add a vent without having to demolish the bathroom? The toilet is next to the tub and the sinks are next to the toilet.
    Thanks for your help.

    Hi Arela,

    A few questions, How old is your house? Is this a "added bathroom"? Do you have a basement or are you on a slab?
    First things first. You have a blocked drain line with a possible broken pipe.
    If the lavatory has a vent snake the vent from the roof. Put out enough cable to reach the base and about 20 feet more. Good luck, Tom

Shower weep hole drain turned into tub drain [ 1 Answers ]

I am remodeling my shower to a roman tub. The existing drain is a weep hole drain. Is there a plug for these type of drains? The idea is to use the same drain system and hot mop, tile, etc. around it.
