PythonNo Spill Fish Tank Flow Switch

This connector is all plastic. Despite that, it holds up pretty good when installed on a Python or similar aquarium hose system. You can also use these to turn on or off the current from a garden hose too. If you have high water pressure, you might wear this valve out faster.Its purpose is to provide a water valve close to where you are holding the hose or siphon. It allows quick shutoff of water without having to run back to the facet to do so. It also allows you to slowly turn on water pressure without the bang or pop spurt you get when first turning on water pressure. It also allows you to continously control the speed and current of the water flow. It can control the flow both ways through the valve. This can be used on the Python hose or any standard hose that uses garden hose sized connectors. Its male on one end and female on the other.Ive used these Pyrhon valves and hose adapters to set up filter devices that don't have valves on several devices. I dont recall ever having one leak or fail to open or close. If you overtighten the connectors, you could crack the plastic. Inexpensive and easy to install and use.

However, if you are buying this as a replacement because you broke the switch on the one you have, you should probably order 2 or 3 more. If you use it as much as I do the little switch gets worn out and if a few bits of debris get stuck as you close it, it is likely to break again so you might as well have a few more on hand as backup, or learn how to crimp your hose really really well on fill-ups...

These things do work! The quality is best in class and you can mix and match these parts to create necessary equipment.I used python to make separate fil and pump-out hoses. This flow valve is used to cut off the flow from the pump out hose to stop the suction.

Perfect replacement for the stock valve on the Python, but that is to be expected. The valves themselves periodically give out, although I have only gone through two valves in several years. They have good quality, they just wear over time, which is to be expected. I appreciate that Python sells the valve separately so I don't have to buy a whole new system just for the valve. Would recommend if you need a replacement valve. Be sure not to leave the valve closed under prolonged pressure as this can cause them to fail prematurely.

Thanks for not changing too much. Just need tubing that stays flexible and doesn't permanently kink in storage. Silicone like the better airline tubing, anyone?

I have four tanks and after a bit over a year of use this switch failed on my Python Water Changer. Replacing this part was easy and far more cheaper than purchasing an entire new Python Water Changer. The Changer is great - can't live without it!

Without this Part water changes become extremely difficult especially between multiple aquariums. It's not intended to be used under pressure for extended periods damage will occur.

I purchased the Python hose (50 ft) and used it 4 times when the valve broke. Company would not replace it. I ordered the replacement at my expense of $10 only to have it defective upon arrival. Apparently the manufacturer is no longer as good as they once were. Does anyone know where I can get one made from a hardware store maybe? Very poor customer service.
