P trap with more than 4 inch water seal

[jrider]

Can anyone tell me if this p trap being this tall is contributing to the sink producing large air bubbles when draining. Is this affecting the venting? Thanks!

That's a U-Trap. U dont no wat ur doin.

With a disposal no less.
Thats a lot of water to push, especially with ground up food.

No wonder they like to squeeze that trap.

Jason-

There's lots of resources on plumbing out there, including the NACHI plumbing course. Here's also a link that I've found useful. I don't think it talks about U-traps but it does give a nice explanation on traps and diagrams of what is appropriate and what is not appropriate. I've put some the of verbiage they used on S-traps into my reports as those are common in my area. And since inappropriate trapping is a health concern, the Center for Disease Control is a solid resource to quote.
