Questions & Answers

How easy is it to pump water by hand?   A person of average strength can easily pump water from a normal depth water well. The environmental sampling / purging hand pump lever handle works on common principles of leverage, providing a ratio of 3.3 :1 leverage. The actual force necessary to pump water with the emergency hand pump is determined by the total length of your drop pipe. A standard installation of 100' only requires about 11.5 pounds per stroke. A well with 200' of pipe will require about 23 pounds per stroke.

How much water will the environmental sampling / purging hand pump deliver?    While pumping rates vary with the frequency and length of strokes used, most people can pump two to three gallons per minute of water.

How deep of a well can I pump?   Pumping depths are influenced by the amount of effort applied to the lever. An average person can easily pump water from as deep as 240' and get about 1.5 GPM.

Can I install the environmental sampling / purging hand pump by myself?   Yes, in fact a person with average mechanical ability can easily install the environmental sampling / purging hand pump, with only minor assistance, in about two hours time. No special tools are required, since a slide in safety tool is provided. A helping hand from a neighbor will make the task smoother, but it would be possible by yourself. If you feel the installation is beyond your ability, we suggest that you contact a licensed pump installer or plumber to install the system. If your static water level is below 250', the manufacturer says you should have it professionally installed to maintain your warranty.

What is the environmental sampling / purging hand pump made of?   The pump's components are made of solid stainless steel and aluminum. The O-rings are  made of Buna-N rubber. Viton O-rings are available by request.

What about using the Environmental Sampling / Purging Hand Pump in freezing climates?    The environmental sampling / purging hand pump can be used in freezing areas of the country without problems. During installation, a small weep hole about 1/16" in size, should be drilled in the pipe below the frost level for your area. This will allow the water to weep down to that level, preventing it from freezing in the pipe. When you start to pump, a few strokes will lift it from the weep down level to the top.

What if my casing is only 2" inside?   The environmental sampling / purging hand pump will install into a well as small as 2" size. The Environmental Sampling / Purging Hand Pump can be supplied with a well cap for 2" up through 8". The 8" cap will have an added cost if needed.

What is the difference between well depth and groundwater static level?   Well depth is the full depth that the well was drilled and cased. Static water level is the depth at which the water seeks its own level. When you are pumping the well, you pump from the static water level, regardless of the depth your unit is set. For maximum protection against water level changes, the manufacturer recommends setting the environmental sampling / purging hand pump at least 20' below the static water level.
