|In response to Re: Venting lavatory sinks|
: I am remodelling my bathroom and the position of the vanity basins is to be moved. I thought I could just drain the new basins into the same drain that the shower and bath go into but looking around your site it seems that this is more complex. I had never heard of venting until I checked out your site! Can someone advise me on how I should do this?
: The bathroom is on the top floor. At present the bath tub drain runs about 10' sloped horizontally, the shower drain runs about 5' - they both are 1 1/2" ABS pipes which join in a Y into a 2" drain which has a 2" vent pipe to the roof which eventually T's into a 3" pipe out through the roof (many other 2" and 3" pipes T into this as well). The existing vanity basins have their own vent pipe but I can't get to this because of the joists.
: On the same wall that the new basins are to be installed there is another 3" vent pipe but I am not sure what it is venting as there is no bathroom beneath this.
: So my questions:
: Hope you can help,
1. Is it ok to run the new vanities into the same drain as the bath and shower?
Good Luck. e-plumber
