Trying to decide if I need to add a vent for tub p-trap.

the pictures show the area the tub will go in (left side)
the right side is where the drain is.

I can face the tub with the drain on the left side but venting the 10ft p-trap would be a decent amount of work

so the tub would need to have its drain on the right, which brigs it roughly in the middle of the room.

if a p-trap must be vented at a max of 5', it might work, otherwise I will need to take a vent up to the crawl space above the bathroom, and then join the vent with the current vent (shown in picture) in the crawl space. Thoughts, suggestions? Would it be a major issue having a p-trap that's vented at 6'?

this may or may not help... the tub will almost never be used... adding it only for lame property value since I removed the tub for a walk in shower (different part of the bathroom)

****MORE INFO****
Tub drain is only 4.5' from the drain-vent in wall that will also be used by double vanity sinks...

Any issues?

I might just put in the drain and cap it. leave it for the next homeowner to decide if they want a tub...

Zxed...

I SEE NO ISSUE WITH HOOKING THE TUB INTO THIS DRAIN. The only question is if WET VENTING is allowed in your area or not.. To determine the answer to this you would need to call a local plumbing inspector and simply ask if you can vent a tub using a 2" vent from the bathroom sink?

If you can wet vent then the tub should not need an additional vent as long as within 5 feet of the pipe.

If you cannot wet vent then you will need to individually vent this tub and the sinks as drawn below... ;)

Let me know what you think...

I'm in CA and I thik since 06 you may wet vent Award winning plumbing, kitchen, water and bath help, discussion and advice forum = Plbg.com (http://www.plbg.com/forum/read.php?1,373433)

Could you update your diagram and show a wet vent only scenario AND (pretty please) include how you would connect a double sink vanity to that line you have on the right (to sink)

No problem... here it is. See below.

I don't think I need a p-trap... they sent me something with the vanity. let me take a pic

I mean, I don't think I need p-traps for the sinks... see attached. what the heck is this?

How would I attach this to my abs drain?

I believe they call that a bottle-trap... this trap may or may not be legal in your area. This is important, especially if you are planning on selling the home down the road... home inspector may flag as illegal and then all would need to be replaced. Call the local plumbing inspector and ask him if bottle-traps are allowed.

If allowed, the trap hooks up as shown below... ;)

If not allowed and since this is a double sink with VANITY BASE then it is just as well to install pvc p-traps and transition over from the trap to the sink pop-up assembly using a 1.5" x 1.25" pvc desanco fitting (last picture).

Good luck!

Thank you. abs in my case. but... regardless of it being allowed or not. if it messes with the storage space under the sink, ill be using the bottle trap. and when needed, will switch to p-trap :) it shdnt be so hard to change between the two ONCE. :)
