I replaced a 7" deep kitchen sink with a 9" sink. Since the sinks are deeper the garbage disposal will not fit around the drain pipe. Is there a flexible pipe that can be used to correct this problem?

Can you post a picture of the piping under the sink? There is always a way to make these type of situations work, but flexable pipes(in most cases) aren't the answer. If you can give us a visual of your problem, we will do our best to help out. If you have a center outlet waste, then you can fix the problem by going to an end outlet waste. It may take some new fittings, but will most likely be your best option.

I think I know what you mean, run into it all of the time during remodeling. Your pipe from the disposal goes into a trap and the horizontal pipe after the trap no longer lines up with the horizontal pipe coming out of the wall, right. If this is what you have the flex pipe will not make water run up hill. You can try to shorten that initial pipe from the disposal or even try reversing the trap trying to gain back the lost 2". A few times I could not solve the I\roblem and had to resort to an S trap which is not allowed by most plumbing codes.

This is exactly what my problem is. At this point in time my only solution appears to be to buy a shorter disposal then I may be able to use the existing drain, after shortening the discharge pipe. As far as code, I live in the country and big brother's long arm hasn't streached this far as of yet. You are correct though about water running up hill. I've never been able to make that happen either. :-) Thanks for the help.

..

Here is a key measurement. Measure perfectly horzontal from the exit hole on the disposal to the verticle pipe coming out of the wall. The pipe in the wall MUST be lower than the exit hole in the disposal to avoid the dreaded water up hill problem. If the disposal is below the pipe in the wall you can try an S trap through the floor. Tearing into the back wall and lower the connection will not work unless that pipe inside the wall is draining straight down, many are horizontal.

I was able to get everything installed by moving the disposal to the opposite drain and doing as you suggest above 'making sure that the disposal WAS higher than the output drain.' I really appreciate all of your help.'

No problem, it's what we are here for.
