## Summary description

Inter-Sano universal float valve with 1/2 x 3/8 connection designed for filling cisterns, water tanks and similar installations. The valve regulates inlet water flow using a float mechanism to maintain a set level, suitable for potable and non-potable water systems where compatible connections are available. Practical for domestic and light commercial plumbing repairs and replacements.

## Long description

Inter-Sano universal float valve 1/2 x 3/8 is designed to control inlet water flow to cisterns and water tanks by means of a float-operated mechanism. The product provides automatic filling and level maintenance for a range of installations where the specified threaded connections are compatible. It is suitable for both potable and non-potable water systems and is commonly used in domestic and light commercial plumbing applications to replace worn or malfunctioning inlet valves.
Advantages
The valve delivers reliable level control through a mechanical float that opens and closes the inlet according to water level, reducing manual intervention. Its universal 1/2 x 3/8 threaded connection makes installation straightforward in systems with matching fittings. The construction is intended for long-term use in typical domestic water environments and allows quick replacement of existing valves without extensive modification of the tank or cistern.
Suitable for
Toilet cisterns and replacement inlet valves
Domestic water tanks and overhead reservoirs
Rainwater harvesting buffer tanks with compatible fittings
Light commercial tanks where automatic level control is required
Key specifications
Connection size: 1/2" x 3/8" threaded fitting
Operation: float-actuated mechanical valve
Application: suitable for potable and non-potable water systems
Typical use: cisterns, water tanks and similar reservoirs
Material: corrosion-resistant components for standard water conditions
How to use
Shut off the water supply before starting installation. Remove the old inlet valve if present, clean the thread and seating surfaces, and apply appropriate sealing tape or sealant to the threads as required. Screw the float valve into the compatible 1/2" x 3/8" connection and tighten securely by hand and with a suitable tool without over-torquing. Restore water supply and allow the tank to fill; adjust the float arm or valve setting if necessary to obtain the desired water level. Verify there are no leaks at the connection and that the valve closes reliably when the set level is reached.
Usage recommendations
For reliable performance, inspect the valve periodically for mineral deposits or debris, especially in hard water areas, and clean or replace the valve if operation becomes sluggish. Use appropriate thread sealant compatible with potable water if the system supplies drinking water. If unsure about compatibility with existing fittings, compare thread sizes or consult a plumbing professional before installation.
