How to Fix a Running Flushometer: A Step-by-Step Guide

Introduction to the Flushometer

A flushometer is a crucial component in commercial and public restrooms, designed to efficiently control the release of water in toilets and urinals. Unlike traditional tank-based systems, flushometers are valve-operated and provide a powerful flush using direct water pressure. While incredibly effective, they can sometimes run continuously, leading to water wastage and higher utility bills.

Understanding how to fix a running flushometer is essential for plumbers, DIY enthusiasts, commercial property managers, and other plumbing professionals. This guide will walk you through diagnosing the problem, provide a step-by-step DIY fix, advise when to call a professional, and offer maintenance tips to prevent future issues.

Understanding the Problem

A running flushometer can be a nuisance, causing water to flow continuously or intermittently when it shouldn’t. This issue often arises due to several common factors:

1. Worn Diaphragm: The diaphragm or gasket inside the flushometer valve controls water flow. Over time, it can wear out or become damaged.
2. Debris and Sediment: Particles from the water supply can enter the flushometer valve, obstructing proper closure.
3. Faulty Handle Assembly: A malfunctioning handle assembly may not return to its original position, leading to continuous water flow.
4. Incorrect Installation: If the flushometer was installed improperly, it could cause operational problems.

Diagnosing the issue requires a keen eye and some basic plumbing knowledge.

DIY Fix for Running Flushometers

If you’re a hands-on DIY enthusiast, you can often fix a running flushometer by following these steps:

Tools and Materials You’ll Need:

Flush the toilet or urinal to drain any remaining water from the system.

3. Remove the Flushometer Cover:

Use an adjustable wrench to remove the top cover of the flushometer valve.

4. Inspect the Diaphragm:

Check the diaphragm or gasket for wear and tear. If it’s damaged, replace it with a new one.

5. Clean the Inside of the Valve:

Remove any debris or sediment using a cleaning brush. Ensure all components are clean before reassembly.

9. Apply Plumber’s Grease:

Lightly grease any moving parts to ensure smooth operation.

When to Call a Professional

While many flushometer issues can be resolved with a DIY approach, certain signs indicate you should contact a professional plumber:

1. Persistent Problems: If the flushometer continues to run despite your efforts, a more complex issue may be at play.
2. Water Leaks: If water is leaking from the flushometer or surrounding pipes, it’s essential to get professional help to prevent further damage.
3. Complex Installations: For intricate installations or systems integrated with advanced plumbing controls, professional expertise is highly recommended.

Ignoring these signs can lead to more severe problems, including water damage and higher repair costs.

Maintenance Tips

Preventive maintenance is key to ensuring your flushometer operates efficiently. Here are some tips to keep your flushometer in top condition:

1. Regular Inspections: Periodically check the flushometer for signs of wear or damage.
2. Clean and Clear: Keep the valve and handle assembly clean and free of debris.
3. Replace Worn Parts: Don’t wait for a complete failure; replace parts like diaphragms and gaskets as soon as they show signs of wear.
4. Proper Operation: Ensure the flushometer is used correctly and avoid excessive force on the handle.

By incorporating these practices into your routine maintenance schedule, you’ll extend the life of your flushometer and reduce the likelihood of unexpected issues.
