Wet Vent Triple

[spyderkeeper]

Hi, I'm arguing back and forth with someone, and I was wondering if you guys could tell me if this is OK or not. As show in the photo, I have a lav, shower, and a toilet that is being added in to a wet vent. If these are the only things on the wet vent would this be ok or would the toilet and shower need a separate vent pipe connecting above?

Is the pipe above where the lav drains a pure dry vent?

Yes, above the three things it's a dry vent

It's a head-scratcher for me. Like to see what the other guys say. Don't know how long the arm is for the shower drain, and I don't like the 180 on the toilet, though it's probably legal.

You're in Cartersville. I'm over here in Cherokee County where Cherokee, Forsyth, and Fulton Counties come together. Black Bear came through my back yard about two hours ago heading west. Snuffled around for a minute and took off through the woods.

The shower and the toilet can combine with a fixture cross, not a sancross.
It would work more to code if you wet vented the shower with the lav and then went to the toilet downline with a wye.
With a sancross, the toilet will skip across the fitting and into the shower arm.
Some places allow a medium 90 below a cross but not everywhere. I've always used a long turn 90 there.
And newer toilets don't work well on crosses. They tend to push water out of the opposing bowl or trap.

Could you not have used an estabrook and stack vented the whole bathroom, I personally would fail it on poor craftsmanship.
1 Estabrook and you were done.

I agree, long pattern fittings, not a wet vent in my jurisdiction.

Wouldn't you have the same problem with the estabrook as the double san tee for the toilet?

Plus, I'm not sure that would fit. However, if it works, I'll give that a try.

I've yet to see a bear in Georgia, saw plenty in NC where I'm from though.
