Thread: Drain and vent installation

This is the first time I have seen something like this. It appears the drain line is on the right and the vent on the left. On the back of this wall is another sink with an air intake valve. I think the vent on the sink connects to the intake valve on the opposing wall. Is this acceptable?

Thx

Mat,

At least not as shown in your photos.

Maybe in some other arrangement, but with that sanitary tee going down, water is going to go down there with it and not just down to the trap.

That thing is just all wrong.

a true git er done,hack job at best. refer to a plumbing contractor for repairs.

Mat,

That drain piping is totally wrong. First off, ABS and PVC pipe cannot be glued together, even if the 'rain or shine' (blue) glue is used, lol. This looks like a feeble attempt to create an 'indirect' drain. If there is a drain on the other side of the wall with an approved vent, these sinks could be plumbed in using a 'cross' fitting and a single vent. Of course 2 approved 'p-traps' would have to be used, (one at each sink tailpiece).

The plumber's response was the drain on the left of the photo is used to prime a trap in the laundry room and the sink drain is vented through the roof. No rebuttal for the ABS and PVC glued together.

The 'plumber' said that? not an acceptable response.

Double trap as now described

Incorrect trap priming with unsanitary method

S traps

Upside down use of a fitting

Vent fittings where sanitary fittings should be used.

No cleanout

Intermediate reduction in trade size

Too much wrong especially with the introduction of a washing machine somewhere.

Network with a different plumber.

Take a look at this.

Mat,

That is showing a typical floor drain trap primer installed off the tailpiece.

That is completely different than the installation shown in those photos above.

Those trap primer adapter tailpieces have about a 1/2" to 3/4" tap coming off them and are made for that purpose.

His set up is just plain screwy.

No problem.

The food goes down the sink drain and into the washing machine trap and blocks it up nicely. Then of course when the washer trap is dry then the washer connection will have the sink to vent thru. Then you have the sink for the washer to back up into so it does not overflow onto the floor in the laundry room. Like I said, no problem

agree with ted. afterall an inspector showed him how to do it and said it was o.k. hope nobody tells this clown it's o.k. to eat glass!

This is what he was trying to do:
