Best water changer/gravel vac

Well normally I would say nether and recommend the Lee's Gravel Vac which used to cost half of what the python cost. But now you can get the Python no spill kit for between $31-$38.

But if you really want to save cash all you really need is one garden hose fittings and the main part if you already have the hose. Truth be told as long as you haven't used your garden hose with a chem or fertilizer sprayer the garden hose and the Python valve is all you need for a fraction of the cost ($6).

I don't like to waste water using one of those Python. I prefer to drain tanks using gravity.

I don't blame you, but it doesn't waste water unless you allow it. I use it cause it great for filling the tank with a standard hose connection and starting the siphon on a tank rather then getting bacteria laden water in your mouth sucking on the hose at the foot of the bathtub.

I just start the siphon then move that hose to the tub while connecting a separate fill up hose to the water eductor to fill up another tank.

Also when Im all done I like to evacuate all the bacteria laden water out of my hoses in the suction mode. The little water I do waste is well spent.

All these valves were designed after the Navel Peri-Jet Eductor used for dewatering flooded ships compartments when no pump was available by just using the water main itself. Was introduced in the early 70's

Why would anyone have to suck on a hose to start a siphon? Submerge the gravel cleaning tube, allow it to fill completely and then raise it so it drains out the hose. Pinch the hose to stop the flow before the gravel cleaning tube is completely empty. Resubmerge and start siphoning.
 
I use the python. works great but we dont sell it anymore so I pray that a piece doesnt break on it.
 
if a piece does break you can find it on the internet so no worries there.
 
And besides that there are no replaceable parts the system is made up of separate generic replaceable components, hose, eductor, hose fittings, vac tube. Anyone of which can be replaced by any of the competitor parts. Just like having socks go bad you don't toss out your wardrobe.

Oh common now I'm sure you sucked on a hose of some type in your life to start a siphon.
