EXT Pond Pump Flow Chart (GPH)
EXT Pond Pump Application
- Start water flow for the first time
- Water needs to be introduced into the suction line before starting the EXT Pump for the first time.
- The kit includes a plumbing tee with a threaded cap on the discharge side that is used as a priming port to add water to the suction line.
- Close the ball valve (turn valve perpendicular to PVC pipe) when filling to make sure the water being added fills the pump volute and suction line.
- The kit includes a 3" swing check valve located beneath the surface of the water. This check valve holds the water in the suction pipe.
- Once filled the threaded cap can be replaced back onto the tee and the pump can be powered on.
- The ball valve can then be opened to allow the flow of water to begin.
- Once primed, the pump can be turned on and off without priming as long as water remains in the suction line.
- Pump won't prim and start the water flow.
- The suction line needs to be filled with water via the priming port.
- Make sure all the plumbing connections are tight, including the threaded union located above the check valve.
- Any air leaks in one of these connections can cause the pump to not prime properly.
- Make sure the check valve is free and clear of debris and is in a vertical position that allows the internal flapper to seal and hold the water in the pipe when the pump is not operating.
- Remove the threaded collar on the union located on the suction side. This will allow the water to drain from the pump. There is a drain plug located below the 3" pump intake that can be removed to further drain any remaining water from the pump volute.
