Knowing Your Water Level

We get lots of calls and emails from prospective customers who want to purchase a hand well pump system from us and proceed to give us their well depth information without including the (Static) or resting water level in their well. Sometimes a customers well will be 400+' deep and they will initially think that our product won't work in their well because it is too deep.
The first and most important aspect of installing one of our hand well pumps is knowing your water level in your well.. You could have a 400' deep well and a water level of 40'.  If your water level is 40' we would recommend that you set your Handy Well Pump at 55 to 60'.  Unless you have a very small diameter well (2") with a very low recovery rate, say a 1/2 gallon per minute, you usually won't need to go any deeper than 20' below the surface of the water.
The second most important aspect of your well is the recovery rate. As mentioned above, a low recovery rate may mean that you would want to set the pump lower than 20' below the surface of the water. This isn't necessarily a big issue. It's very easy to add an extension or two if you find yourself running out of water during prolonged pumping in a dry season.
Discovering the water level can be accomplished in several ways.
  • Check your property records at your local county or city office.
  • It's marked on the side of some well casings.
  • Ask your well driller or or pump installer if they have the records.
  • You can use a simple measuring device like the one shown on the right. Simply tie a steel nut onto a roll of string and then attach a small fishing float to the string about an inch or two above the nut. Look at the image. Slowly lower the string down into the well until the string goes slack. Tie a knot in the string at that point. Raise the string back out of the well, keeping it in a straight line. Measure the distance between the float and the knot. That is the water level in your well. So, knowing your water level is very important before you proceed! You can also use a fishing line.

        If you have a small diameter well with obstructions in it such as a pitless adapter, you can lower a piece of   1-1/4" pipe down to just beyond the obstruction and lower the string inside the pipe. This will keep you from getting tangled.
