Experiencing toilet troubles in your San Jose home? You’re not alone. Toilet malfunctions are a common household issue, but understanding the root of these problems and how to fix them can save you both time and money. This comprehensive guide will walk you through the essentials of toilet repair, highlighting common issues, their solutions, and detailed steps to ensure your toilet functions efficiently.


It is important to understand the basic components of your toilet:

  • Tank: Holds the water needed to flush the toilet.
  • Bowl: Receives waste and water from the tank during flushing.
  • Flush Valve: Controls water release from the tank to the bowl.
  • Fill Valve: Regulates water refill in the tank post-flush.
  • Flapper: Seals the water in the tank and opens during flushing.
  • Handle: Initiates the flushing action.

Knowing these parts helps in diagnosing issues and performing effective repairs.


Common Toilet Issues and Their Repairs:
1. Constant Running

A constantly running toilet not only wastes water but can significantly increase your water bill. This issue is usually caused by a faulty flapper or an improperly adjusted float. Here’s how to fix it:

  • Check the flapper: Ensure it’s not worn or warped. Replace it if necessary.
  • Adjust the float: If the water level is too high, it may continuously run. Adjust the float mechanism downwards to lower the water level.
2. Weak Flush

A weak flush is often due to clogged holes under the toilet’s rim. To resolve this:

  • Clean the rim: Use a small mirror and a wire hanger to remove any debris from the rim feed holes.
3. Clogs

Toilet clogs are a nuisance and can be caused by flushing inappropriate items or a build-up of waste.

  • Use a plunger: A plunger often resolves simple clogs. Ensure a good seal and pump vigorously.
  • Try a toilet auger: For deeper clogs, a toilet auger can reach further into the drain.
4. Toilet Leaks

Leaks are common and can occur at various points around the toilet, such as the base, the tank, or between the tank and the bowl. Leaks not only cause water wastage but can also lead to structural damage.


Causes and Fixes for Toilet Leaks:
  • Worn washers or bolts: Check the tank bolts and washers; replace them if they look corroded or worn.
  • Faulty supply line: Ensure the line supplying water to the toilet isn’t leaking. Replace if necessary.
  • Wax ring issues: If the leak is at the base, the wax ring (seals the connection between the toilet and the drain pipe) may need replacing. Remove the toilet and replace the wax ring.


While many toilet repairs are straightforward, some problems might require the expertise of a professional plumber, especially in cases of persistent leaks, complex clogs, or if the repairs done don’t resolve the issue.
