The answer to 'garbage disposal low water pressure' is that there are several common causes, including a clogged disposal, a blocked drain line, or low water pressure in the home. Symptoms may include slow draining sinks, gurgling sounds, or the disposal not running at full power.
To troubleshoot, first check the disposal for any clogs or debris. Use a flashlight to inspect the drain and look for any obstructions. You can also try running the disposal with the water on full blast to see if that clears the issue. If the problem persists, the issue may be with a blocked drain line or low water pressure throughout the home, which will require a professional plumber to diagnose and resolve.
