Wonder Pump 6 ft. Siphon Hose

about the length of the 'jiggle' mechanism, say 3"

The good news is that it will suck it dry - ONCE YOU GET IT STARTED. The bad news is you need to jig the valve end of the hose up and down quickly in about 5” of fluid AND have enough fluid to fill the hose to get it started. Great product for emptying large volumes of fluid (I use mine to put gas in my boat and to empty my hot tub) but, unless you are starting with a full tank with enough depth, it’s probably not the best choice for a small project.

My guess would be that the valve connected to the end of the hose needs to go into the liquid to be siphoned out. There is a real possibility that it could get stuck or caught on something when you try to remove it from the tank or even break free from the hose connection and end up in your tank. Otherwise, it works pretty good - emptied my hot tub with it last month.

The check valve, which gets immersed in the liquid being drained, i.e. the tank, could come off ! Also, the lash in the tube would make it difficult to prime.

yes, just find a larger diameter hose to go over the one supplied, or, find one smaller to put into the one supplied. hope that helps :)

I would not recommend an extension to this, it clearly works more poorly (more difficult to siphon). That was part of my plan when I bought the siphon hose. I was hoping to redirect rain water (set up a system from collection barrel to nearby bushes). Siphon simply would not work with any length or width of additional hose. I still have to use a bucket to carry water, :(

Yes, you can add many more feet of length to the device, as long as the source that you are siphoning from is higher than the end of the new length of hose. The greater the difference in height, the greater the flow..., but within reason. There is a thing called "friction loss" that'll limit the length of your hose. Ask any firefighter that has gone to school. Happy dribbling!

no

You can just cut a short piece of PVC pipe (smaller in diameter than the tubing) to serve as a connector and extend the tubing with however much more tubing is required.

yes it does

Yes to get gravity to work.

Yes, the unit uses gravity to keep the water flowing, there is no pump so it can not be higher than the area that you are siphoning from. Hope this helps

Yes ... unless you can make water flow uphill.

yes

Always.

Yes it does, at lease the top level of your source.

Yes it does. It's gravity flow.

No.Just make sure the tank you are filling is face due North. If you are pulling water from a lake uphill, just point the hose end to the North in the area you are filling. I have pulled water up 40 feet from one pond to fill a smaller pond. You may need to tie a horse shoe type magnet on the North end of the filling hose. Hope this is useful.

Yes, it is a siphon hose not a pump.
