I've always wondered about the volume of water in the hose when you decide you've removed enough water. My imagination doesn't see it draining into the sink on it's own, or being easy to evacuate... unless there's some secret to the python besides it being a hose. So I imagine a hose that long could hold a fair amount of water, and when you decide to switch it into fill the tank mode, are you just getting a big dose of old tank water right back into the tank before the freshwater hits?
 
yeah, every time I do a water change, I try to do a little more than I would have done otherwise because I have that same thought in mind.... well, I do when I do a WC on the tank that is emptied while connected to the faucet. I have 2 tanks that I do water changes with. One tank, I throw the hose out the window to water the bushes when taking the water out. When that is done, I connect it to the faucet. No problem. It's the tank I do that needs the suction from the faucet to remove the water that is the issue... I get the water down pretty low when taking it out... because I consider the water still in the tube that will be going back in...

btw... I can't believe I didn't get confused with this one LOL
 
Hmmmmmm......

So, if the inside diameter of the Python hose is 3/4", (which it is not, I believe), and the Python was 50 feet long, the approximate volume when filled would be about 265 cubic inches or 1.1 US gallons....
 
If yur worried and don't have the time to just pull the python out to drain before refilling just drain a little more than yur normal WC, simple! Sometimes ya gotta stop overthinking things and just do it :)

I just lift mine out of the water to help it drain the hose or I put the tank end in the sink and switch to "fill" and let it flush the hose before refilling.

Pretty simple method.
 
Once I am done with syphoning, I pull the syphon out of the water and wedge the tip of it under the edge of the tank. I then go to the sink to match the water temp, but first I turn the water on full blast until all I get is air through the syphon. I find that doing that before matching the water temp and closing the valve to send the clean water back to the tank almost all of the water has come out of the hose and into the sink.
