See The Drain Strainer™ with Crown Adapter installation instructions and dimensions (or the XL installation instructions and dimensions below for taller sinks) below to see the actual dimensions for each model. The legs can adjust up to an additional 5 inches and you can add as many sets of 6 inch leg extensions as needed to achieve the proper total height.
Most seals and pipes are located beneath your kitchen sink. It is common for these pipes to be jarred when people are using that space. If the pipes are struck hard enough, they can shift and sit improperly, causing retaining bolts to loosen and seals to be shifted into awkward positions. If your leak is coming from this area, you will need to reattach and reseal these pipes. Fixing this issue may require an experienced, licensed plumber.
Disposers fasten to the sink drain fittings in a number of ways--some use threaded plastic nuts, others large hose clamps--but the mounting-ring assembly shown here is the most common. To remove the disposer, support it from below and rotate the large, 3-tab mounting ring at the top counterclockwise until the unit falls away. Remove the remainder of the drain assembly by loosening the three bolts and prying off the retaining ring. Push the drain out through the sink hole and clear away any old caulk or putty.
When rubber gaskets age, they can develop leaks. The gasket can dry up, crack, and leak when it is repeatedly exposed to long periods of disuse where no water is present in the drain pipe. Should an older garbage disposal be removed and then placed back, it will require a new rubber gasket to again achieve a watertight seal. Moreover, if a gasket is not evenly locked on all three sides, then it will develop a leak.
If your garbage disposal is making a clicking or rattling sound, there may be some food particles that will not grind up inside. Remove power from disposer, reach into the sink hole with a pair of tongs and remove anything that is still down in the disposer. Test your disposer to be sure the noise is gone. If not continue troubleshooting your disposer issue (see below).
