Common Spare Parts

The widely requested Fluidmaster spares include flush valves, fill valves, seals, and dual flush conversion systems. Unsure which you need? Our Identification Service is there to assist you.

• Flush valves: Common replacements for leaks and incomplete flushes.

• Fill valves: Needed for slow fills and noise issues.

• Seals and gaskets: Required to maintain watertight connections.

• Flapper units: Use when there are continuous leaks into the bowl.

Common Faults and Fixes

Leaking cistern

Typically due to a worn-out flapper or valve seat. Replace to ensure a tight seal.

Constant running

Often due to a faulty seal or misaligned flush valve. Photo of the valve assembly can help confirm the type.

Noisy fills

Usually caused by high pressure or worn valve components. Identification is best handled with proper photos of installations.

Weak flushing

Flushing performance can decrease with a worn-out valve seal. Pictures of the flush mechanism can help identify what needs replacement.

Slow filling

Usually caused by a blockage or a faulty fill valve that needs replacement.

Inconsistent flush pressure

Affecting dual flush systems, often needing a photo for precise part identification.

Technical Support FAQ

How do I identify my Fluidmaster flush valve model?+

Look for a model number stamped on the valve body or near the base. Clear photos can assist if details are unclear.

Why is my Fluidmaster filled cistern still noisy?+

This is usually due to water pressure or worn valve parts. Sending a photo for a clearer identification of the fill valve can help resolve it.

What photos should I send for the Fluidmaster Identification Service?+

Send complete item photo, close-ups of markings, photos of removed components, and a measurement tool for scale.

How do I identify a fill valve type?+

Check on the valve cap and body for model numbers or photos of each component.

What if my Fluidmaster part has no code or markings?+

This scenario is common with older components. Use photos and measurements to identify parts based on shape and size.

What should I do if my dual flush system isn’t working properly?+

Verify that all components are correctly aligned and seated. A photo illustrating your current setup can hasten diagnosis.

Can I still identify a valve type if it's inside a cistern?+

Yes, take clear photos of all visible parts and the surrounding area inside the cistern.
