What is a ball valve?

Why do water tanks overflow?

How to fit a ball valve in a water tank

How often do ball valves need replacing?

A ball valve or float valve is used within water storage tanks as a flow control appliance, which features a pivoting, spherical float to allow water in or out based on the current water level. The valve will respond to a drop in the water level by opening and encouraging flow to enter the storage tank. Once a predetermined level is reached, the valve will close off supply by reaching its shut-off position.

Cold water storage tanks will often overflow due to the use of faulty or deteriorated float valves. These flow control devices are prone to damage from the likes of limescale, grit or dirt, resulting in an inability to provide a watertight seal. On top of this, general wear and tear can crack or split components of the ball valve, effecting the standard of its function. If you want to avoid your tank overflowing, we recommend using a professional contractor like Tank Reline to carry out installation of your ballcock valve to ensure that the valve is suitable for the system and is installed correctly.

  1. Shut off mains supply to the system.

  2. Loosen the tanks inlet pipe.

  3. Detach the inlet pipe.

  4. Unfasten the retaining nut.

  5. Insert and attach the new float valve.

  6. Reattach the inlet pipe.

  7. Turn mains back on and test function of new ball valve.

Generally, we advise that routine ball valve inspections should be carried out at least every 12 months to assess their condition. As for repairs and replacements, correctly installed ball valves should not need to be replaced regularly, as long as they are subject to a robust maintenance and inspection regime. A properly maintained ball valve can last for years, if not decades.
