Replace the kitchen sink splash guard

Jam a screwdriver into the locking ring and rotate it away from you. The disposer will drop onto the books. Support it with one hand so it doesn’t tip over.

Grab the lower edge of the old rubber guard and peel it up and off. Then slip the new one on and push it down until it seats.

Shove several shims between the books and the bottom of the disposer until the locking ring just touches the sink flange. Then just rotate the ring to lock it in place. Reinstall the drain line, do a leak test and grind away.

Got a garbage disposer that spits, um, garbage at you? Forget about replacing the entire unit. You can install a new splash guard (about $10 at a home center) in about 20 minutes. You don’t need any special tools.

If your garbage disposer is hardwired, start by flipping off the circuit breaker. If it plugs in, unplug it. Stack up books or lumber to support the disposer. Then remove the drainpipe and disconnect the quick-connect fitting (Photo 1). Replace the old splash guard with a new one (Photo 2).

The hardest part of reinstallation is hoisting the disposer up and into place with one hand while you try to engage the locking ring with the other. Forget about that. Use our tip in Photo 3.
