Pack of two 32mm rubber diaphragm washers for ball float inlet valves. Approximately 5mm deep and suitable for part 2 and 3 valves, compare with existing washer to ensure compatibility.


Stop leaks and restore filling consistency – with a 32mm rubber diaphragm

The rubber diaphragm sits against the inlet valve seat and compresses to form a watertight seal, closing as the cistern refills. Diameter and depth match common ball float valve recesses to create reliable contact.

A proper seal prevents continuous running and restores normal fill cycles, reducing wasted water. Expect a noticeable reduction in refill time and fewer noisy overflows.

Quick maintenance without specialist tools – thanks to a simple cap-and-replace fit

Replacement requires isolating the inlet water supply, unscrewing the float valve cap, swapping the worn washer for the new rubber diaphragm and re-tightening the cap. No adhesive or sealant is necessary.

Most householders can complete the repair in minutes, avoiding a call-out to a plumber. A straightforward DIY job returns the cistern to service with minimal fuss.

Keeps existing inlet hardware working longer – with durable rubber construction

Rubber material resists compression set better than degraded plastics and conforms to the valve seat to maintain a tight seal over repeated flush cycles. Approximate 5mm depth preserves correct seating geometry.

Replacing the worn washer restores performance without swapping the whole filler unit, extending the life of the inlet assembly. Suitable for routine maintenance and quick fixes between larger repairs.
