How to fix a sink drain pipe that is too short
Drain pipes that are a fraction of an inch too short lack the proper engagement depth to stay securely connected under vibration or pressure. This causes the slip joint to periodically work loose and leak, forcing constant manual checks and makeshift fixes.

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
- 1Placing a pan underneath the leaking joint to catch water

“So i put in a new sink a little while ago. I think from the picture you can see the right pipe is just a hair short like 1/2 to 3/4 inches. Every so often it works its way loose and leaks (hence the pan).”source ↗
