Hello,
I have an Insinkerator Model 77-79 that was draining slowly. On inspection of the outlet pipe, there is an internal piece of nylon or poly tube that has folded in upon itself causing the outlet to be partially blocked. Is this piece replaceable/needed?
It is like a sleeve that is inside the machine between the flange where the outlet pipe connects and the impeller itself.

Thank you!

Randy,
I have exact same problem. Were you able to resolve it?

Hi HelmHog,

What I figured out was the plastic is all one piece that is a liner that forms the outlet from the disposal. I think it cracked, allowing water to corrode the case, causing it to deform the poly outlet tube.
Surprisingly, I didn't have much water infiltrate the motor assembly, but it was the demise of the machine, I ended up buying a new one!

The new ones are amazingly quiet!

Hi Randy,

My problem was exactly the same as yours - poly outlet tube deformed and folded back on itself through incorrect attachment and sealing of O-ring and metal adapter plate to outlet pipe, restricting water flow and promoting sludge build-up. Took unit to local repairer who replaced whole central casing and innards for A$295. He mentioned that unit should run for another 25 years and they are one of the best and solid units ever built. Replacement price for similar unit was over A$1,500. Very Happy camper!

Cheers.
