Hello. I just had a new double sink installed in kitchen. One bowel is larger than the other. The larger bowel is of course used to wash dishes, the smaller to dry. The plumber installed the p-trap under the smaller bowel. Should the p-trap not be installed under the larger bowel. Also, how high should the san tee be in my stack. Right now its about 6 inches from the cabinet bottom and thus the p-trap is about 3 inches from the cabinet floor. Is there not a minimum height p-traps and drains are supposed to be at?

Thx. Oops on the bowl....I am getting a real hollow sound in my sinks when the water drains. I thought that might have something to do with the height of the p-trap as there is over about a foot for the water to drop down to the trap. I thought stack might be blocked, but its clear, even poured hot water down it. Any idea why the hollow sound.

The tailpiece (from sink to top of trap) should be less than 24". If longer then the flow of water might cause the trap to empty out because of the velocity of the draining water. But by the same token the shorter the tailpiece the less velocity you will have. Follow me? I think what you have now is perfect as you won't have to worry about the trap clogging up over time.If the trap wasn't holding water you would have the odor of sewer gas in the area.

Me office1
Is the tail piece 11/2 and the P trap 2" x 11/2"

A lot of codes do allow the use of this undersized trap 11/2" trap in lieu pf 2 x 11/2
