FAQs
How do I know the seal needs replacing?
Typical signs are continuous trickle into the pan, intermittent refilling sounds, or a visibly flattened/perished seal.
Is it easy to fit?
Yes — isolate water, flush to empty, remove the valve top (twist-release on most 550 valves), swap the seal, refit and test.
Will this fit all Fluidmaster valves?
No — this seal is for the 550 Series. Check your valve model before ordering.
Do I need any sealants?
No sealants are normally required. Ensure mating surfaces are clean before refitting.
