Key Features
- Universal Application: Perfect for replacing cracked, waterlogged, or degraded floats in any standard cistern.
- High Buoyancy: Precision-engineered round design ensures a clean shut-off of the water supply once the tank is full.
- Durable Material: Resistant to the chemicals and scale often found in hard water areas.
- Eco-Friendly: Reliable shut-off helps prevent silent leaks and overflowing into the waste pipe.
Installation Tip
Before fitting the new float, inspect your metal float arm for signs of corrosion or bending. Gently screw the Qualifloat onto the threaded end of the arm until secure. If your toilet is still running after fitting, you may need to slightly bend the arm downwards or check the washer inside the ballvalve itself.
