Flushometer Parts Breakdown: Learn How to Anticipate Needed Parts article

Preventative Maintenance for Sloan Flushometers

Sloan has been manufacturing plumbing solutions since 1906. They are the industry leader in commercial plumbing systems, and have been the most trusted name in flushometers for over 110 years. Sloan manufactures dozens of flush valve models, and has two of the most well known manual flush valves on the market today: The Royal and Regal manual flush valve series. Sloan creates high quality flushometers that have stood the test of time. There are Sloan units that were designed a hundred years ago that are still in service today. So when Sloan introduces a preventative maintenance guide for one of their most popular product lines, you should pay attention.

Flushometers undergo intensive industry testing, and must meet strict criteria to hit the marketplace. One of those tests involves successfully completing a minimum of 250,000 flushes. This may sound like a lot of flushes, but in commercial facilities like airports, hospitals, sports arenas, tourist locations, and private facilities like prisons that get over 5,000 flushes per month, that 250,000 flushes is met in only four short years.

After 250,000 flushes, some parts within the unit will need to be replaced. Knowing the signs that indicate when certain parts need to be replaced is valuable information for any maintenance department.

Why Should You Be Proactive Maintaining Flushometers?

By understanding the lifespan of the parts in your flush valve, you can anticipate problems before they occur, and have the necessary repair parts on hand. You can even install the new part at the first signs of deterioration, instead of waiting to fix the flush valve when it’s no longer operational.  This is especially helpful in restrooms that are very popular or have a single stall. Be proactive in maintaining the flush valves in your facility, and save yourself from future headaches by planning for the inevitable replacements that will happen in the future.

Sloan Flushometer Maintenance Schedule

Sloan Manual Flushometer Maintenance Schedule

This guide will show you the average life expectancy for some of our popular Sloan parts based on our actual repair experience. There are many factors that contribute to the life expectancy of flushometers and their parts.

These factors include the following:

  • Water Quality - High levels of chlorine or debris can erode parts over time
  • Vandalism and Abuse - Public buildings and facilities are more susceptible to misuse and damage
  • Proper Installation - Improper installation of the product can affect performance, and accelerate deterioration
  • Proper Parts Replacement - Non-Sloan replacement parts can negatively impact performance and reduce product life

Sloan flush valves and Sloan repair parts have a longer life expectancy than other industry units and parts. Sloan repair parts are estimated to last between one to five years longer than similar parts manufactured by other vendors.
