Installation of In-Line Water Pumps
An in-line pump is a pump that sits in between the intake of the water source and the final destination of the water. They are often used at lakeside cottages that do not have water service, or to pump water to an irrigation system. They offer advantages over submersible pumps in that they can be placed in convenient housing near a power outlet, and can be easily accessible in case they break down. However, they must be primed manually which could require some extra work.
- Measure and cut a length of pipe to reach from the water source to the pump. Slide the barbed end of a threaded female adapter into the end of the intake pipe and secure it with a hose clamp. Thread a foot valve into the adapter and place it in the water, making sure it is not resting on the bottom.
- Slide the other end of the intake pipe onto the intake barb of the water pump. Hold it in place with a hose clamp.
- Slide a brass T-fitting onto the outlet barb of the water pump. Attach a pressure gauge to one end of the T, and use a male-male adapter to connect the outlet pipe to the other end. Use plumbers tape when screwing in the adapter and pressure gauge to the fitting.
- Prime the pump and fill the intake line before turning the pump on. This will ensure that no air gets into the pump, which could damage the seals.
