quick question, lets say I dont want to waste my water down the drain. How can I use the python to drain the water into my yard. Obviously it wont have the water pressure sucking up the gravel, do I have to buy this thing? http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=18544
well you could, but that is just to start the siphon. you could just suck on the hose to start the siphon and save the money, thats what i would do. besides, i think swallowing a little fish tank water every now and then is healthy for you!!!
just make sure the hose does not travel on an incline to the yard and let gravity take care of the rest...
