Product Description

Fast Water Tank or Cistern Fill with this Ballcock Alternative

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

Designed as a replacement 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.This makes the pump more efficient, saves energy and wear and tear on the pump.

QuickStop has a very high flow rate allowing rapid filling with minimal pressure loss.

Available in five different sizes, 0.5", 0.75", 1", 1.25" and 1.5" BSP Connections.

It has not been WRAS tested, so is currently only available for non-potable water installations.

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, 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.

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.

  1. Brilliant product 5 Star Review

    Posted by on 14th Apr 2021

    Does what it's designed for.We have a bore hole and the pump was continually going on and off because the conventional ball valve was letting water by long after the pump had stopped.
    The only thing that let it down was the problem we had with the courier APS overnight not delivering the item ( kept saying there was no one available to sign for item 3 times) had to phone customer services a number of times get our item delivered.
