Why Is Your Garbage Disposal Leaking?
Like any plumbing device, garbage disposals can spring leaks. These leaks can happen in various places and parts. Read on to learn about some common causes of these leaks.
Your garbage disposal uses a ring-shaped flange to connect to your sink. This part helps water run into the unit. If it develops a fault, then your unit will leak from the top. Flanges can fail if their rubber gaskets or seals develop a problem. If these parts wear or break, then they can't contain and direct water as they should. They also leak if the putty that makes their connection waterproof cracks or breaks away. In some cases, flanges work loose over time. They might need to be retightened to create a watertight fit.
You can sometimes resecure the flange to stop it from leaking. For example, your plumber can tighten the connection and install a new putty seal. However, if a rubber seal or the flange itself is broken, then you're more likely to need a new part.
Supply Line Problems
Your garbage disposal has a supply line that carries waste out into your drain. It also has a hose line that prevents waste from backing up into your dishwasher. If one of these lines cracks or breaks, then you might see some leakage coming out of the side of your unit or the line itself. If the line has a loose or broken connection, then the water will come out at this point and run down the line.
If you have a loose supply line, then your plumber might be able to tighten its clamps to get rid of the leak. However, if the line or one of its connecting parts is broken, then you will need a replacement.
Unit Seal and Cracking Problems
Sometimes, a garbage disposal leaks because of a problem with the unit rather than with one of its parts. If you can see water under your unit, then it probably has a problem. Sometimes, these leaks happen because seals in the unit break or wear down with age. Once a seal can't do its job, your unit isn't watertight. Older or damaged systems can also crack or break. Water will then come out of the base of your unit.
Your plumber might be able to replace faulty seals. However, these problems are usually a sign that an old unit is close to the end of its working life. Your plumber might recommend that you install a new system.
To find out more about the source of your leak and whether it can be repaired, contact a plumber. If a repair won't work, they can install a new unit for you.
