A running toilet can be caused by several issues:

Step 1: Check the flapper. The flapper may be worn or warped, causing water to leak into the bowl. Replace the flapper if it is damaged.

Step 2: Examine the chain. The chain connecting the flapper to the flush handle may be too long or too short, preventing the flapper from sealing properly. Adjust the chain length if necessary.

Step 3: Inspect the float. If the float is set too high, the water level in the tank will be too high, causing continuous water flow. Adjust the float to the appropriate level.

This issue may be caused by a partial clog or an issue with the flush mechanism:

Step 1: Check the flush handle and chain. Ensure they are connected and functioning properly.

Step 2: Inspect the flapper and float. Make sure they are functioning correctly and sealing properly.

Step 3: Use a plunger to remove any potential partial clogs in the toilet trap or drain.

A leak at the base of the toilet may be due to one of the following issues:

Step 1: Check the tightness of the bolts securing the toilet to the floor. If they are loose, tighten them carefully, ensuring not to overtighten and crack the toilet base.

Step 2: Inspect the wax ring. If the wax ring is damaged or not sealing properly, it may cause leaks. Replace the wax ring and reseat the toilet.

Signs that your garbage disposal may be broken include:

• Inability to turn on or off.
• Humming noise without any grinding action.
• Slow draining or water backing up into the sink.
• Persistent foul odors, even after cleaning.
• Leaks around the disposal unit.
• Frequent resetting is required.

If you suspect your garbage disposal is broken, it's best to call a professional plumber for an inspection and repair.
