Overview
An adjustable rubber flapper seals the flush valve in the toilet tank, and its adjustment lets the flush be tuned for water use. It attaches to flush valves with or without mounting ears, and a chain links it to the flush handle.
Fluidmaster's adjustable design helps a worn, leaking toilet stop wasting water, and the rubber resists chemicals and hard water. The listing never states which flush valve size it fits, so check the valve before buying.
Who it's for
Homeowners fixing a running toilet or a weak flush get an easy tank part that suits many common valves. Anyone unsure of their flush valve size should measure first, since the listing does not name one.
Pros and cons
- Adjustable for flush control
- Works with or without mounting ears
- Resists chemicals and hard water
- Flush valve size not stated
- Model numbers differ within the listing
Performance notes
Sealing depends on the rubber seating cleanly against the flush valve opening, which the chemical and hard water resistance helps preserve. Adjustment changes how the flapper behaves during a flush, so flush strength and water use can be balanced.
