 too many traps and fittings?
Author: sum (FL)

I have a double sink. Left side has a garbage disposal and the right side does not. The left side has a trap then drains to the right side which then has a trap too.

Once in a while when I run the garbage disposal it vibrates and shakes and some fitting will come loose and water splashes everywhere. I had this happened twice in the last three months.

So, I think this is because the whole contraption (done by last owner) has too many fittings. I counted nine.

Is the picture below the way it should be hooked up? I kind of think may be the trap between the garbage disposal and right drain is not needed. Any advise?

Thanks,

Sum

It is double trapped. The trap out of the disposer needs to be eliminated. Instead of the j-bend out of the disposer, use a flanged tailpiece straight into the tee. make sure you have a baffle tee.


Peace out,

code in california states that the garbage disposal discharge should go down directly to the trap. connect the right side of the sink using an end out let asembly. the current configuration is definetly wrong

joint runner is 1000% right. hard pipe the drains. put a cleanout tee in the pipe as it comes from the wall. the current configuration is a disaster waiting to happen..

That is what happens when a handyman or homeowner installs the disposer and only knows how to use the fitting that came with it. The disposer has two traps, but it is not "double trapped" which is a different situation altogether. It is not "illegal" or "wrong" just a poor installation. If you buy a "disposer connection kit" it will have the correct tube for the disposer outlet and a baffle tee, although your tee should be a baffle tee already. I remove "hard piped" sink/disposer connections, I do not install them.

...and if you have low hot water pressure, un-kink the supply hose. Better yet, remove them and install rigid supplies or at the very least, the metal braided type.

in massachusetts, it is illegal to have a slip fitting on the outlet side of the trap. so i routinely remove slip piping and replace it with hard piping. the only slip joints i put in are the disposer ell and the strainer tailpiece. consequently, the homeowner can store things under the sink without dislodging piping.

If you have been reading your own posts, you will see that almost everything is illegal in MA.
