Household plumbing that is. I know basic sinks have have a t-fitting on the drain pipe behind the wall...one side goes down and out to the main drain and the other goes up to a roof vent for better flow. My question is does it matter if the vent tube goes straight up to the vent or can you use elbows to make 90 degree bends and then go up to the roof? My kitchen sink sits against a wall that has my main entryway on the other side. I'd like to take out part of the wall to open up the room so you can see thru to the kitchen. I would guess that as long as there's airflow it would work but thought I would see if anyone knew for sure.

Please excuse the crappy drawings I want to go from whats on the left to whats on the right.

Thanks.

 

Im thinking about that episode on the 3 Stoogies, when they were plumbers. Remember Curly had all of those pipes in the bath tub. LMAO

 

Hey, I'm no Bob Villa, but I ain't THAT bad at home remodeling...just not sure about that vent thing...

 

i dont see why it would make a difference....but i could be wrong....

 

the whole point of the pipe is to relise (sp) pressure so as long as the pipe cant get water in it (for mold reasons) and it is un blocked then no it does not matter howmany bends there are. the only reasons other pipes go straight up is to save pipe and money and its easyer. just as long as your drain pipe to the sewer has a negative bend (v-trap) so sewer gases dont come up your drain and the vent is after the negative bend u will be fine

 

Thanks for the info!!!

 

do plumbers make good money ???????????

 

Yes they do because its becoming a job that no one wants to do anymore. They make very good money.

 

Try calling one on a holiday (like today), after hours or a weekend and see how much they charge...that should answer your question.

 

you should be fine, the thing with the sewer gases is taken care of by the p-trap underneath your sink. as long as the p-trap is consantly filled with water you should never have a prob with the smell. you will know if you have it correctly installed cause it resembles a letter p when looked at it sideways.
and for the info i used to be a plumber but got int to hvac...a little more money lol
