I just almost finished installing our new GE dishwasher. When we ran it, the drain leaked at the garbage disposer inlet. When I tightened the clamp (much more than it seems it should need), the leak stopped. Then I removed the hose. It seems to me that the hose coupler is too large for the inlet, so the seal is not tight enough.
The drain hose that came with the dishwasher has a customizable boot that connects to the inlet. The boot can supposedly work with 5/8" and 1" inlets. The disposer is an Insinkerator Pro SS unit. After a lot of searching, I have not been able to determine what the inlet size is. It's difficult to reach and see, but by holding a tape measure up to the inlet, it appears that the inside dimension is 5/8". The outside dimension is definitely less than 1".
So here's the problem. The way the drain hose boot is adaptable is by cutting off the 1" portion to reveal the 5/8" portion. If the Insinkerator inlet is not
5/8", the hose is trash. What should I do to solve this dilemma?
