Flowflex Float valves provide a mechanism to fill water tanks, such as toilet cisterns. As the water level rises inside the tank, a float rises as well forcing the valve to shut and therefore stopping the flow of water. Our range of brass float valves can be used for water tanks, troughs.
Unpack and check that the valve is correct for its intended usage. The valve must be compatible with the system design, pressure & temperature requirements and must also be suitable for the fluids it is intended to carry.
Check that the flow paths are clear and that the threads are free from debris.
To ensure ease of operation, maintenance and repair, the location of the valve should be decided during the system design phase. Valves should be appropriately supported to prevent strain on the valve and the pipework.
Ensure Float Valve Stem is connected tightly with Ball.
Remove the Float Valve Hex Nut / Gasket from the valve body.
Tighten the Hex Nut / Gasket to the Float Valve Threads with Water Tower. Add PTFE Tape to the Float Valve Thread and tightly connect Float Valve with water.

We recommend that all systems are throughly tested upon completion. Whenever possible, completed systems should also be flushed to remove debris.
Regular maintenance is the most efficient method of ensuring longer term uninterrupted operational efficiency. It is recommended that within the 1st year that valves should be visually inspected for leaks and that a complete manoeuvre cycle is carried out to check the valve and prevent scale from forming every 3 months. Where a valve is working under extreme conditions it is recommended to check it more frequently.
In hydraulic based installations, the system may be tested to 1.5 times the working pressure of the system. If higher test pressures are required, then please contact us for further advice.
