Here's a good one.
I bought a 25' python....added a 20' extension....now if I'm to reach the sink, I figure I need another 20' extension
total length....a whopping 65 feet....:eek:
(the tank is at my workplace and this is the nearest faucet)
1. will it work?
2. is siphon ability going to be reduced due to the length?
any takers? :)
My Python originally was a 50', but when I added more tanks in other rooms I had to add a 20' extension, for a total of 70'. I cannot tell any difference with or without the extension, so it stays on all the time. I can't see why you would have any problem.

To get water to my office tanks, I had to use 125 feet (!!!) of Python hose to reach a sink. I found the drain feature really slowed down, and I ended up getting a Mag pump that I place inline to drain the tank. For a smaller tank this would probably not be necessary.
(I've since moved offices and I'm next door to a maintenance closet. I now have a 100 foot roll of Python hose that's not used much....)

isn't that the way it always goes... Buy it and then you don't need it. But throw it away and you need it within weeks.:)
I'm going to get the extra length and give it a shot. In case it comes down to it, can I get some info on the mag pump. Never seen one. Only heard passing remarks about it.
My luck.. they'll end up adding a sink 5 feet away from the tanks after I do all this;)
I think the problem with a longer hose losing suction would have to do with hose sidewall tension. If your hose is limp, your suction will be too way down the line (somebody stop the innuendo :D ) Try using one of those braided hoses they use for higher pressure lines.

I never had much trouble with the hose collapsing when in 'suction' mode, unless the flow control valve got closed. If you consider the length of run and the size of the tube, there has to be a lot of friction going on as the water gets pulled 100+ feet. A braided hose might help, but it would be more useful for when you have to shut off the control valve after the tank is filled and then run down the hall to shut off the faucet. I'd hate to have to coil and store 65 feet of braided hose every time I did a water change. Python hose is bulky enough...
Jim
So long as the hose is stored as a coil and not kinked, I don't see any potential problems. If you store the hose with kinks, those will be potential collapse points in suction mode - even with braided tubing.
I wasn't really thinking of hose collapse but rather soft hose walls weakening the suction. I had always thought that a rigid pipe would hold vacuum more efficiently than a soft rubber hose, even before the point of hose collapse.
Matak - certainly rigid (or better, reinforced) wall tubing will hold suction far better than molded-only tubing, provided that it has not been stored kinked - in which case you get deformation memory involved. Then it may function worse than simple molded tubing. I can't tell you how much obscenely expensive tubing in the lab I've had to toss or save to cut for short connections because some klutz had kinked it to store more compactly.

Make sure you NEVER run really hot water through it or you may have collapsing. That was my problem with the pythons.

Are you saying that it may collapse at that time, or it will be prone to collapsing after the hot water treatment?

Thisis what happened i used hot water to fill an old tank. The drained it. It appears the tube was still to warm because it now collapses Close to the spic

python sells a 100" version, so it should be no problem.

I just made a DIY Python from a drain/fill device and 1/2" clear vinyl hose from the hardware store, with garden hose end pieces and a ball valve. It is 50 feet long, I'm hoping to be able to do 3 tanks scattered all over the house from one central sink.
I'll be using it tomorrow for the first time.... any advice? --particluarly as to how to prevent kinks and how to keep it from growing mold inside.
There is a small suction cup attached to the tank end, I'm hoping that that will allow me time to run to the sink without the hose slipping out of the tank. The draining part doesn't have me as worried as the refilling.
I added 15 feet of hose to mine and I can definately tell a difference in the suction.I only use the extra hose for 1 tank then I remove it for the others. It just dosnt have the power. Tim
