I have a 3/4 HP disposer. I am having problems with clogs at the T fitting above the P trap where the horizontal pipe from the disposer connects. It seems the deflector which reduces the opening size inside the T fitting is the cause of the problem.

I previously had the same problem and fixed it by removing the low flow restrictor in the old standard kitchen faucet which increased the water flow and solved the problem. I recently installed a new faucet with a pull out spray hose which has low water flow and the clog problem reappeared. I am not sure if there is a similar solution and looking for some input.

I was also wondering if there is some way to increase the opening size of the deflector inside the T fitting.

The pipe size is standard 1 1/4 pipe.

You have several problems.l The first is your pipe size. 1 1/4" is not the average sink pipe size. 1 1/2" is the smallest size that's in use today. The second is the tee itself, (see image) this type of tee chokes down on everything. If this were my call I would reconfigure the drainage under the sink. I would wye off from the wall stubout and have a separate trap for the sink and disposal. To see more infornation click on:

Good call, Tom.

I had the same problem in our new house. The baffle inside the T connector (just like pictured in Speedball1's link)worked almost as effectively as a fine-meshed screen to plug up every time we ran the disposer. I went to the hardware store to buy a tee without the dumb baffle (I figure water knows to follow gravity and doesn't need the help of a plastic traffic director). The guy at the hardware store said that they make all the tee's that way, and that he always has people coming in with this problem. He said he cannot get tee's without the baffle, and suggested I get my Dremel tool with a little burr on the end, and grind/cut out the baffle. The next time the sink plugged, I tried it. It took less than ten minutes of oral surgery on the tee. Things work great now, and indeed the water and ground up goodies do go down, not up, even without the baffle!
