Toilet Repair Solutions: Fix Leaks, Ballcocks & Running Toilets

A properly functioning toilet is something we take for granted until problems arise. From constantly running toilets to leaking cisterns and faulty ballcocks, toilet issues can cause significant water waste, increased bills, and frustration. This guide covers common toilet problems and their solutions to help Exeter homeowners understand when DIY fixes are possible and when it's time to call a professional plumber.

Common Toilet Problems and Their Causes

Understanding what's causing your toilet problems is the first step toward finding the right solution. Here are the most common issues we encounter in Exeter homes:

• Constantly running toilet - Usually caused by a faulty fill valve (ballcock) or flush valve that isn't sealing properly, allowing water to continuously flow from the tank into the bowl.
• Leaking toilet cistern - Often due to worn seals, cracked components, or loose connections between the tank and bowl.
• Weak flush - Typically caused by partially clogged jets under the rim, a partially blocked siphon, or insufficient water in the tank.
• Toilet won't stop filling - Usually a problem with the ballcock or float mechanism that regulates water levels.
• Toilet overflowing - Most commonly caused by a blockage in the toilet trap, drain pipe, or main sewer line.

Fixing a Constantly Running Toilet

A toilet that continues to run after flushing is not just annoying - it can waste thousands of liters of water per month, significantly increasing your water bills.

Diagnosing the Problem

To determine what's causing your toilet to run continuously:

1. Remove the toilet tank lid carefully and set it aside on a safe surface.
2. Flush the toilet and observe the mechanism as it operates.
3. Check if the flapper is sealing properly. If water continues to seep into the bowl, the flapper may be worn or warped.
4. Inspect the fill valve (ballcock) to see if it's shutting off properly when the tank is full.

Common Solutions

Based on your diagnosis, here are solutions for repairing a running toilet:

• Replace the flapper valve - If the flapper is not sealing correctly, purchase a replacement flapper appropriate for your toilet model from any hardware store. This is an inexpensive and straightforward DIY repair.
• Adjust or replace the fill valve - If the fill valve isn't shutting off properly, you might need to adjust the water level or replace the entire valve assembly.
• Clean mineral deposits - Sometimes mineral buildup prevents components from sealing properly. Clean with vinegar or a specialized toilet cleaner that removes calcium and lime deposits.

Ballcock Replacement Guide

The ballcock (fill valve) is crucial for proper toilet operation, regulating water flow into the tank after each flush.

If your toilet's ballcock needs replacement, here's a simplified process:

1. Shut off the water supply to the toilet using the isolation valve typically located behind or near the toilet.
2. Flush to empty the tank and sponge out any remaining water.
3. Disconnect the water supply line from the fill valve.
4. Remove the old fill valve by unscrewing the locknut underneath the tank.
5. Install the new fill valve following the manufacturer's instructions.
6. Reconnect the water supply and slowly turn it back on.
7. Adjust the water level as needed and test by flushing several times.

Preventing Future Toilet Problems

To avoid frequent toilet repairs, follow these preventive maintenance tips:

• Don't flush anything other than toilet paper and human waste
• Conduct periodic checks for leaks by adding food coloring to the tank - if color appears in the bowl without flushing, you have a leak
• Clean your toilet regularly to prevent mineral buildup
• Consider a professional plumbing inspection annually, especially for older toilets
• Replace worn components before they fail completely
