A inline water pump is device used to pump water from one location to another. As the name states they are typically in line with the hose that’s carrying the water. Not only water but these pumps are able to pump all kinds of liquids, but water is the most common liquid used.
An inline water pump can be sued for a variety of projects. Basically any time you need to transfer water, you are probably going to need one of these. I recently had my back yard flood out and needed to pump the ground water over the fence and into the street. My house was at risk of taking on water and needed to pump the water quickly. I ran to the local hardware store (Home Depot) and bought a inline electric water pump. I believe with tax and all it was around $45. The problem I had was I did not have a hose to add the inline water pump to. I took my garden hose cut it in half and installed it in the middle of the hose. Plugged in the pump and let the sucker ran overnight. The next morning I went outside and that little water pump was on its last leg, but emptied all that ground water. In the past I had a inline pressure pump that I tried and it was ridiculous. Trying to pump all that water by hand was impossible.
