This website answers just about any question you may have about pumps, wells, and drinking water. Even before performing water quantity, quality, equipment function tests, there is an enormous amount we can determine about
a building's water supply just by looking at the equipment.
Articles here provide details on water pumps, tanks, controls, and wells and water supply inspection, diagnosis, and repair.
The photograph shows a one-line jet pump, the water pressure tank, and a water softener. We know from the fact that this is a single line jet well pump that the well is a shallow one, probably less than 27' deep. Well depth may have implications
for water quantity and quality and vulnerability to surface water contamination.
The page top photo shows our client holding the open top of his well casing along with some unusual well casing exit plumbing at a drilled well with a modern steel casing.
Our sketch at left, courtesy of Carson Dunlop, shows the basic components of a drilled well with a submersible water pump.
Finding
the location of your well and inspecting the condition of the well piping and equipment are an important first step to assure a functional and potable drinking water supply - that is, having enough water supply and having water that is safe to drink.
Knowing the type of well you have and the type of pumping equipment will be very important in diagnosing any water pressure, flow, or supply problems. The articles listed below provide detailed advice on diagnosing and repairing problems with water
