Commercial Flushometer Repair — Keep Your Restrooms Working
Flushometer repair, replacement, and installation for commercial restrooms throughout the Triad.




















When the Flushometer Fails, the Restroom Is Out of Service
Commercial restrooms depend on flushometers — the flush valves on toilets and urinals that handle hundreds of flushes per day. When they fail — running constantly, not flushing properly, or leaking — you’ve got an out-of-service fixture, water waste, and unhappy customers or employees.
All-Star Plumbing repairs and installs flushometers throughout High Point, Greensboro, Winston-Salem, and the Triad. We work on all major brands — Sloan, Zurn, American Standard, Kohler — and carry common repair parts for fast service.
Flushometers are built for heavy use, but they have internal components that wear out. Diaphragms, seals, handles, and sensors all need periodic service. Regular maintenance keeps restrooms running; neglect leads to emergency calls.
Signs Your Flushometer Needs Repair
Flushometers give warning signs before complete failure. Know what to watch for.
Flushometer Won't Stop Running
- What it means: The diaphragm, relief valve, or control stop isn't sealing properly. Water runs continuously.
- Why it matters: Water waste adds up fast — a running flushometer can waste thousands of gallons per day.
Weak or Incomplete Flush
- What it means: Not enough water volume or pressure. Could be clogged bypass, worn diaphragm, or water supply issue.
- Result: Bowl doesn't clear properly, requiring multiple flushes or leaving waste behind.
Flushometer Won't Flush at All
- What it means: Handle mechanism failed, sensor not working (on automatic models), or internal blockage.
- Result: Fixture is out of service until repaired.
Handle Is Hard to Push or Sticks
- What it means: Internal components binding, mineral buildup, or worn handle mechanism.
- Fix: Usually internal rebuild or handle replacement.
Water Sprays From Flushometer
- What it means: Failed seal, cracked cover, or loose connection. Water sprays out during or after flush.
- Urgency: Immediate — water damage and slip hazard.
Sensor Not Detecting (Automatic Flushometers)
- What it means: Sensor failure, dead battery, or sensor lens dirty/obstructed.
- Fix: Clean sensor, replace battery, or replace sensor unit.
Flushes Randomly (Automatic)
- What it means: Sensor sensitivity issue, reflection problems, or failing sensor.
- Result: "Ghost flushing" wastes water and startles users.
Noisy Operation
- What it means: Water hammer, worn internal parts, or pressure issues. Loud bang or extended noise during flush.
- Fix: Internal rebuild or pressure adjustment.
Flushometers We Repair & Install
We work on all types of commercial flush valves.
Manual Flushometers
Traditional handle-operated flush valves. User pushes handle to flush. Reliable, simple, and common in most commercial restrooms.
Brands: Sloan Royal, Sloan Regal, Zurn AquaFlush, American Standard
Sensor-Operated Flushometers
Automatic flush valves with infrared sensors. Detect user presence and flush automatically. Common in high-traffic and touchless restrooms.
Battery-Powered Sensor Flushometers
Sensor flushometers powered by batteries rather than hardwired. Easier installation but require periodic battery replacement.
Hardwired Sensor Flushometers
Sensor flushometers connected to building electrical. No battery changes but require electrical connection during installation.
Toilet Flushometers
Flush valves for commercial toilets (water closets). Typically 1.6 GPF (gallons per flush) or 1.28 GPF for high-efficiency models.
Urinal Flushometers
Flush valves for urinals. Typically 1.0 GPF or 0.5 GPF for high-efficiency models. Smaller than toilet flushometers.
Common Flushometer Repairs
Most flushometer problems are fixable with internal parts replacement.
- Diaphragm Replacement
The diaphragm is the main working part of the flushometer. When it wears out, the flushometer runs constantly, flushes weakly, or won’t flush at all.
Frequency: Typically every 3-7 years depending on usage and water quality.
- Handle Repair/Replacement
Handle mechanism wears from repeated use. Replacement restores proper operation.
- Vacuum Breaker Replacement
The vacuum breaker prevents backflow. When it fails, water may siphon or the unit may not flush properly.
- Control Stop Service
The control stop is the shut-off valve built into the flushometer. May need cleaning, adjustment, or replacement.
- Sensor/Battery Replacement
For automatic flushometers — sensor replacement or battery change when detection fails.
- Complete Rebuild Kit
When multiple internal components are worn, a rebuild kit replaces all wear items — diaphragm, seals, springs, guide.
Flushometer Installation & Replacement
Sometimes repair isn’t practical and replacement is the better option.
- When to Replace Instead of Repair
- Multiple components failing
- Obsolete model with unavailable parts
- Upgrading to sensor-operated or high-efficiency
- Visible corrosion or body damage
- New Construction Installation
We install flushometers in new commercial construction — properly sized for the fixture and water supply.
- Retrofit to Sensor Operation
Upgrade manual flushometers to touchless sensor operation. Popular for hygiene and reduced maintenance.
- High-Efficiency Upgrades
Replace older 3.5 GPF models with 1.28 GPF high-efficiency units. Significant water savings in high-traffic facilities.

Flushometer Questions
How much does gas line installation cost?
Most repairs run $100-$300 depending on parts needed. Diaphragm replacement is on the lower end. Full rebuild or sensor replacement costs more. We quote before starting.
How long does flushometer repair take?
Most repairs take 30-60 minutes per unit. We carry common parts, so same-visit repair is typical.
How often do flushometers need service?
Depends on usage. High-traffic restrooms may need service every 2-3 years. Lower usage facilities every 5-7 years. Signs of problems warrant immediate attention.
Should I repair or replace my flushometer?
If internal parts fix the problem, repair usually makes sense. If the body is corroded, parts unavailable, or you want to upgrade to sensor/high-efficiency, replacement is better.
What brands do you work on?
All major brands: Sloan, Zurn, American Standard, Kohler, and others. We can source parts for most commercial flushometers.
Can you convert manual flushometers to automatic?
Yes. Retrofit sensor kits can convert many manual flushometers to touchless operation. We assess compatibility and install.
Why is my sensor flushometer flushing randomly?
“Ghost flushing” is usually sensor sensitivity or reflection issues. We adjust sensitivity or reposition the sensor. Sometimes sensor replacement is needed.
