    ~ World's Greenest  WATER PUMP ~

    I was using it at an elevation of 110' above the pump. That said, the delivery pipe was made of pvc and was over 700' long and 3/4" diameter so being non-rigid plus that long, it must have reduced my output flow considerably because the pump had 16 gallons of water in the delivery pipe resisting each cycle. The shorter the delivery pipe vertical lift the more water it will deliver. So if you have to travel water a long way, go as straight up as you can from the pump and then let gravity run the water downhill to your end delivery point. Remember the ancient Romans and their aquaducts...

    slight misunderstanding. the innertube is still inside but I drilled a hole through the plastic pipe tank and installed the innertube valve stem through it so it sticks out the side of the tank and can be used to fill the tube from the outside of the tank without taking apart the tank so the pump does not have to be stopped and drained to fill up the innertube.

    Hi Shawn, There are a number of ways to improve efficiency (as measured by amount of water delivered per minute)1, position gate valve downstream of pressure tank.2. adjust pump cycle rate for optimum delivery (requires timed testing on site)3. use an internal pressure bladder (bicycle tube or use bladder tank) instead of snifter valve 4. install additional pumps delivering to same delivery pipe to increase flow (avoid pumps larger than 4" or smaller than 1.5") 5. if delivery site is a long horizontal distance away from pump, set up the minimum vertical delivery point possible and use gravity to deliver water to the end use location. (like an aqueduct system) The less water your pump must push up a pipe to the end use location the more volume it will deliver. e.g. if your end ...

(like an aqueduct system) The less water your pump must push up a pipe to the end use location the more volume it will deliver. e.g. if your end use location is 400' away and 50' above your pump and you connect a 1" delivery pipe, the pump has to generate enough pressure to move the volume of water in the pipe ( 15085.71 cubic inches) on every cycle. But, if you can locate your delivery pipe so it is 51' vertical to your pump and 349' sloping down to your end use location, the pump must only move 1923.42 cubic inches of water on each cycle, gravity will take the water the rest of the way to your delivery point. This will cause your pump to perform less work and deliver more volume on each cycle.
