The Simple Pump mechanical hand pumps are designed to be permanently installed in domestic groundwater wells in parallel with the existing submersible electric pump.

There are relatively few, if any, comparable products currently available and as such there are several questions that are frequently asked.

Within the following paragraphs we have provided detailed responses to these questions. After reading through this information, should you have additional questions or concerns please call us at (800) 455-2201. Alternatively, feel free to send your question via e-mail to us at . We will do everything we can to properly and thoroughly address your question(s).

Q. "How deep can it pump from?"

A. As a mechanical hand pump, the maximum pumping depth is directly related to the amount of effort applied to the lever arm. We believe that the average person can easily pump from depths up to 200 feet. We estimate that the maximum effective pumping depth is approximately 290 feet, but for emergency drinking water only. As a practical matter, we suggest to our customers that if you are looking at an installation deeper than 200', that you look at one of our Solar Water Pumps - that has no hand pumping ability. It will be strictly a solar pump, and will need a well casing diameter of at least 4".

Q. " How much water will it pump?"

A. Pumping rates from the Simple Pump vary directly with the frequency and length of strokes of the lever arm. Operated normally with a reasonable amount of effort the pump will produce approximately 2 - 3 gallons per minute.

Q. "Will I have to take out my existing electric submersible pump to install the Simple Pump?"

A. In most applications the Simple Pump will readily fit in your existing domestic well without removing or disrupting your existing pump and motor.

There are a couple of pump installation configurations that we have encountered that are problematic for the normal homeowner and may require the assistance of a pump installer to complete the installation. One such configuration is when the existing pump discharge pipe protrudes from the top of the well cap. In this configuration, the existing submersible pump and discharge piping is entirely supported by the well cap. The pump and string of discharge piping, depending on the pump's depth setting, can be very heavy requiring mechanical assistance to lift the assembly. In this instance contact a qualified pump installer to provide you with assistance during the installation process.

A second condition arises in some deeper submersible pumps that have been installed using what are commonly referred to as "torque arrestors" or "centering guides". These fittings act to keep the discharge piping from the submersible pump in the center of the well and reduce the twisting effect, or torque, caused by the pump turning on and off. It is difficult to determine if an existing pump assembly is equipped with a torque arrestor or arrestors. Under normal applications the drop pipe assemblies freely slide into the well casing. If however, during the installation of your Simple Pump assembly, you encounter difficulty in sliding the drop pipe into the well, there may be a torque arrestor in place that the Simple Pump is hitting on. If you encounter this condition, carefully remove the Simple Pump assembly from the well casing and contact a qualified pump installer for assistance. The Simple Pump will still fit, but will require special alignment of the drop pipe assemblies to fit through openings in the torque arrestor(s).

The final condition that may be problematic during the installation of the Simple Pump occurs with relatively small diameter wells, typically 4" and smaller or well casings that are not vertically aligned. The size of the pump's discharge piping relative to the well's casing diameter will determine the ability to easily install the Simple Pump assembly. The largest diameter of any of the Simple Pump components is 1-5/8" and will normally fit beside the pump's discharge piping in a 4" diameter well. If, during the installation process, you encounter difficulty or binding as the drop pipes are being slid into place, you may need to contact a qualified pump installer to provide assistance.

Q. "Can I install it myself?"

A. In most applications a person with average mechanical ability can readily install a Simple Pump assembly with only minor assistance. A typical installation can easily be completed within two hours. After you have completed your installation you can help your neighbors with theirs and will take less than one hour per installation.

Q. "What parts will wear out?"

A. The Simple Pump assembly is constructed of durable materials that will not easily wear out. The pump assembly, pump head, pump cylinder and check valves are all stainless steel; the pump rods are aerospace fiberglass with stainless steel ends; and the drop pipe is Polyvinyl Chloride (PVC), Schedule 80. Finally, the pump's lever handle assembly is solid aluminum.

There are a series of four "o-rings" at various locations in the pump assembly. Each of these is made of a durable rubber product referred to as "Buna-N". Replacement o-rings, if ever needed, are commercially available at most hardware stores or spares can be purchased directly from us.

Q. "How hard is it to pump water?"

A. Pumping water from normal depths with the Simple Pump system is easy. The lever handle that is standard equipment with our pump system works on common leverage principles and provides a leverage ratio of 3.3:1. The actual force required is dependent on the total length of drop pipe assembly. For a standard installation of 100 feet, the equivalent force required is approximately 13 pounds downward. At 200 feet, the equivalent force required per stroke is approximately 26 pounds.

Q. "What is it made of?"

A. Components of the Simple Pump system are manufactured from stainless steel, aircraft grade fiberglass, or aluminum. The pump assembly, pump head, pump cylinder and check valves are all stainless steel; the pump rods are aerospace fiberglass with stainless steel ends; and the drop pipe is Polyvinyl Chloride (PVC), Schedule 80. Finally, the pump's lever handle assembly is solid aluminum.

Q. "What size well will it fit in?"

A. The dimension of the largest component of the Simple Pump system is approximately 1-5/8" OD. Therefore, as a stand-alone application, the Simple Pump could be installed in a nominal 2" diameter well casing. Routinely, without removing the existing submersible pump or its discharge piping, the Simple Pump system is installed in domestic wells with nominal diameters in excess of 4".

Q. "How long does it take to install?"

A. If you possess average mechanical ability and are somewhat familiar with the installation of routine plumbing or irrigation piping, the Simple Pump installation can be easily accomplished within a couple hours with only minor assistance. The second time you install a Simple Pump system (helping a friend or neighbor) you will be able to complete it within an hour.

If, however, you are not quite that adept in mechanical applications we strongly recommend that you contact a qualified pump installer or licensed plumbing contractor to assist you.

Q. "I live in an area that freezes often. How does it work in that environment?"

A. The Simple Pump was designed similar to a non-freeze hydrant and allows the upper column of water to bleed off to a depth below the frost line. The pump, therefore, works well in that environment. Proper precautions should be taken each fall to ensure that the weep hole has not become obstructed.

Q. "How long has Simple Pump been in this business?"

A. Although the Simple Pump Company is relatively new, the design and manufacturing process is the direct result of collaborative efforts between two engineers working in related fields. The first, a mechanical engineer who is responsible for the pump's design and high quality workmanship, has been involved in the design and manufacturing of large scale mechanical equipment for nearly 20 years. He owns and operates the machine shop that produces the pump assembly and directly supervises the Company's quality control and quality assurance procedures. The second is a civil engineer that has been practicing in the area of water and wastewater system design, including design of large diameter municipal water wells, for nearly 16 years. Collectively, they have in excess of 35 years of related experience.

Q. "Is there any lead in the Simple pump?"

A. The pump assembly and its component parts are manufactured from lead free materials and is in compliance with the federal water quality standards as promulgated in 40 CFR 141.85 Section 2.2. Simple Pump components are also in compliance with the even more stringent California proposition 65 requirements.

Q. "How do I determine the depth to groundwater or static water level?"

A. Depth to groundwater is difficult to accurately determine without the benefit of a well sounding device. You can approximate the depth to groundwater from the well driller's drilling log when the well was initially drilled. In the absence of this information, contact a local well driller or practicing engineer to have the water depth confirmed by sounding or other measurement technique.

Q. "What is the difference between well depth, groundwater depth or static water level?"

A. Well depth is defined as the full depth that the well was drilled or cased. "Depth to groundwater" and "static water level" are synonymous phrases and define the depth or distance from the top of the well to the level of water within the well. This distinction is important, as the static water level is the depth from which water is pumped irrespective of the depth that the pump is set. We normally recommend, accommodating natural groundwater level decline, that the Simple Pump be installed to a depth at least 20 feet below the static water level.

Q. "Can the pump really develop enough pressure to fill my pressure tank?"

A. Yes. Simple Pump has been manufactured to very stringent tolerances, which affords the opportunity to develop sufficient pressure to fill a residential pressure, or bladder tank. Pressurizing a tank is equivalent to a lower water level which increases need force on the handle.
