The special connector fitted to a normal household tap creates a vacuum when the tap is turned on full pressure. (In this mode, the tap water goes to waste down the sink). This vacuum draws water from the aquarium through a gravel cleaner and into the sink. Once the required amount of water has been removed from the aquarium, the tap connector can be switched to allow the tap water to refill the tank through the same hose.

The Python No Spill Clean & Fill Water Changer tap connector has a rubber tap adaptor with a circular 3/4" internal centre and is then secured by means of the hose clip supplied. The lower end of the tap adaptor has a screw thread for attaching the Python Clean & Fill main water flow/venturi.

(Customers please note: since we do not keep a stock of the various house taps on the market on our premises, we regret we are unable to advise on the suitability or otherwise of the Python system with your specific tap version.)
