Waterway 1" / 25mm On / Off Valve - Mushroom Top

$35.00 $42.00
Tax included Shipping calculated at checkout.


Waterway On/Off Valve often used for neck, shoulder jet control or waterfalls, as well as other applications. Particularly suited to controlling outlets above water level where complete shut off is desired such as Waterfall, Neck Jets, Laminar jets and other features.
This valve has been copied by many Chinese manufacturers that are impossible to find. We've found that in almost all cases, the internal & cap parts can retrofit into the inferior Chinese copies. Check measurements to compare, or bring into our shop. 
Note, newer valves are sometimes darker grey than others.

  • 100% close off seal.
  • 1" / 25mm slip sockets on bottom and side.
  • Barb adaptors can also be used for hose flexible plumbing.
