Ballcock Replacement - Fast Water Tank or Cistern Fill

The Quick Stop Advance Float Valve is designed as an alternative to conventional ballcock valves in water tanks to protect booster pumps. The Quickstop goes instantly from fully open to fully closed, preventing repeated stop/start cycling of pumps when filling tanks or cisterns.

The QuickStop plastic float valve has a very high flow rate allowing rapid filling with minimal pressure loss.

Available in sizes: 0.5", 0.75", 1", 1.25" and 1.5".

The Locking lever easily sets the minimum and maximum tank liquid levels (for Quickstop valves which also have an adjustable arm length see our QuickStop Advance - Adjustable range).

Can be used in water tanks, toilet cisterns, roof tanks, shallow tanks, header tanks instead of a ballcock and float valve.

When water is drawn from the tank, the Quickstop has a delayed re-start level of approximately 3cm, which further reduces the stop/start frequency of the pump.

QuickStop float valves are hydraulic water level regulators with a hydraulically operated closure.

What does the QuickStop size refer to?

The size refers to the connections. The Inlet is a BSP sized male thread (the outlet is a male barbed fitting).

QuickStop SizeInlet BSP  Size*Minimum hole required
(if putting inlet through cistern wall or similar)**
0.5" 1/2" (12.7mm) 0.825" (21mm)
0.75" 3/4" (19mm) 1.041" (27mm)
1" 1" (25.4mm) 1.309" (34mm)
1.25" 1 1/4 (31.75mm) 1.65" (42mm)
1.5" 1 1/2 (38.1mm) 1.882" (48mm)

* BSP sizes are the nominal bore of the fitting not the measurable thread size, which will always be larger.

** note if drilling a new hole to put inlet through, the instruction manual says to drill 2mm larger.
