I got this idea from the python siphon that hooks up to the sink. It uses a venturi to create the siphon. I wanted to make siphoning easy, so that I would actually do it, and not have to do a water change at the same time. I tee'd off my return pump, and added a venturi, which is directed to a sock. This way I can siphon as long as I want and siphon the bottom of the sump, which is on the ground.
All the parts were just a few bucks.
I took a 3/4" tee, with one side threaded, and 3/4" thread to barb adapters I found in the sprinkler section at home depot. Lowes has them too.
I trimmed most of the threads off one of the barbs, so I could fit it inside the tee, and still fit the pvc. Theres a little lip inside the tee, which holds it in place. Then attached the other barb adapter to the threaded side of the tee.
Now I just attach the downspout and tubing, open the ball valve, and start siphoning.
Note, if you have to much restriction(90's) downstream of the venturi, it will not work. This took a few trys in the bathtub to find an orientation that worked. I also used a threaded ball valve, so I could try different variations.
At the other end of the tubing I used another barb, attached to a short section of pvc, to siphon in tight places.
