How to Choose the Right Hand Pump for Your Well
Choose a hand pump well pump by pumping water level, total head, stroke output, casing clearance, freeze protection and sanitary well sealing.
Choose hand pump well pumps by the lowest expected pumping water level, not total well depth. Use a shallow-well suction pump only when water remains comfortably within its rated suction lift; practical lift is commonly limited to about 25 feet. If the pumping level can fall below that range, use a deep-well pump with its cylinder submerged in the well. Then verify total head, output, casing clearance, freeze protection and the sanitary seal.
Enter the pumping level, delivery elevation and required pressure to screen the pump type and calculate head.
Screening Result
Deep-well cylinder indicated
149.3 ft head
Includes 80 ft pumping level and 69.3 ft of pressure head; friction is 0 ft.
Confirm the exact pump, cylinder and fittings are rated for this head and duty.
Add Friction Loss
Source note: the 25 ft suction screening limit follows EPA shallow-well guidance; pressure head uses Michigan EGLE’s 2.31 ft of water per psi conversion. Friction must be estimated for the actual piping.
A 150-foot well whose water remains 12 feet below the pump may accept a shallow suction pump. A 40-foot well whose water falls below 25 feet while pumping generally needs a submerged pumping cylinder. Total well depth still matters for positioning that cylinder, avoiding obstructions and planning installation.
Shallow and Deep Hand Pumps Work Differently
| Pump arrangement | Pumping element | Appropriate use | Main limitation |
|---|---|---|---|
| Shallow-well pitcher or suction pump | At the surface | Water stays within rated suction lift | About 25 feet practical lift; air leaks can prevent priming |
| Deep-well cylinder pump | Below the water | Water is too deep for suction or varies substantially | More drop pipe, rod weight and installation work |
| Pressurizing deep-well pump | Submerged cylinder with sealed discharge | Elevated tanks or compatible pressure systems | Pressure adds head and operating effort |
A surface pump does not pull water upward like a rope. Its piston reduces pressure in the suction pipe, allowing atmospheric pressure to push water up. The practical limit is below the theoretical atmospheric limit because of elevation, water vapor pressure, friction and other losses.
The EPA describes above-ground jet pumps as shallow-well equipment generally used at depths of 25 feet or less (EPA). Treat 25 feet as a screening limit rather than a design target. The selected pump’s rated suction lift may be lower under the actual site conditions.
A deep-well hand pump avoids that suction restriction by placing a positive-displacement cylinder below the water. The handle moves a rod and piston. Check valves admit water beneath the piston and then lift it through the drop pipe on successive strokes. A USDA Forest Service maintenance guide illustrates this cylinder, rod and drop-pipe arrangement (USDA Forest Service).
Measure the Pumping Level, Not Just Well Depth
Collect the following values from the well record or have them measured:
- Static water level: The water level while the well is resting.
- Pumping water level: The level while the well produces water at a stated rate.
- Drawdown: The difference between static and pumping levels.
- Seasonal low level: The lowest credible level during drought or peak use.
- Total depth, casing and screen details: Information needed to position the cylinder under the pump instructions and applicable well code.
- Existing equipment depth: Required when the hand pump will share the casing with a submersible pump.
Michigan’s water-well manual defines static level as the level with no pumping, pumping level as the level during pumping and drawdown as the difference between them (Michigan EGLE).
Do not select a pump from a remembered well depth or the length of the electric pump’s drop pipe. The hand-pump cylinder must remain submerged at the lowest expected operating level, with the submergence and bottom clearance required by its manual and local rules.
If no reliable pumping-level measurement is available, the correct cylinder depth and required head remain unknown. A static level alone does not show how far the water will fall during sustained use.
Pressure and Elevation Increase the Required Head
Pumping into an open bucket at the wellhead is the easiest duty. Sending water uphill, into an elevated cistern or against pressure in household plumbing adds head.
Required head is approximately the elevation from the pumping water level to the delivery point, plus pressure head at the delivery point, plus friction loss.
Pressure converts to head at about 2.31 feet of water per psi. Michigan’s pump-sizing worksheet uses that conversion and adds elevation, friction and pressure head to obtain total dynamic head.
For example, assume the pumping water level is 80 feet below a wellhead delivery point and the pump must produce 30 psi there. The duty is about 149 feet of head before friction: 80 feet + (30 psi × 2.31 feet per psi) = 149.3 feet.
Do not assume every deep-well hand pump can pressurize a house. The manufacturer must explicitly rate the exact pump head, cylinder and fittings for closed-system pressure and the full required head. The source material provides no universal maximum head because that limit is model-specific.
Also confirm how the hand pump will connect to or remain isolated from the electric-pump system. Relief, pressure-tank and backflow requirements depend on the installation and local code.
Output per Stroke Determines Filling Time
Deep-well hand-pump manuals may publish displacement in ounces per full stroke. Theoretical flow in gallons per minute equals ounces per stroke multiplied by strokes per minute, divided by 128.
At 30 complete strokes per minute:
| Rated displacement | Theoretical flow |
|---|---|
| 4 oz/stroke | 0.94 GPM |
| 8 oz/stroke | 1.88 GPM |
| 12 oz/stroke | 2.81 GPM |
Actual delivery may be lower because users slow down, strokes are incomplete, valves wear or the pump works against pressure.
Current Bison manuals show why displacement must be checked for the exact product. One cylinder is listed at approximately 4 ounces per stroke in its 2-inch deep-well pump manual, while two inline cylinders are listed at 8 and 12 ounces in the inline pump manual. These are product-specific figures, not universal hand-pump ratings.
A larger cylinder moves more water per complete stroke but exposes more piston area to pressure from the same water column. That increases force at the piston. At substantial lift or discharge pressure, a smaller cylinder requiring more strokes may be more usable than a larger cylinder that some household members cannot operate comfortably.
A Shared Casing Requires a Physical Clearance Check
A hand pump sharing a casing with an electric submersible must pass the existing drop pipe, electrical cable, splices, pitless adapter and any cable guards or torque arrestors. Nominal casing size alone does not establish clearance.
Before ordering, document:
- Casing inside diameter and material.
- Existing pump diameter and installed depth.
- Drop-pipe size and position.
- Electrical cable position.
- Pitless-adapter type and its projection into the casing.
- Well-cap pattern and vent arrangement.
- Clear space above the well for installing and retrieving pipe-and-rod sections.
Manufacturer fit rules differ. One current dual-installation guide describes a 4-inch casing as only conditionally suitable, depending on the submersible pump, while larger casings provide more clearance (Simple Pump).
Another design requires pulling the electric submersible and connecting it below a stacked hand-pump cylinder. Its manufacturer strongly recommends using a licensed well installer with suitable lifting equipment. Never force a cylinder past an obstruction; a jammed assembly can turn a backup-water installation into a complete pump-pulling job.
Freeze Protection Must Match the Pump Design
“Freeze-proof” should describe a documented drainage arrangement, not merely a metal pump head. Some outdoor systems use a small weep hole below the local frost depth so water near the surface drains after use. The pump must refill that drained section on the next use, so delivery is not immediate.
Do not improvise the hole. The Bison standalone-pump manual cited above specifies a 1/8-inch weep hole below the local frost line. The company’s pressurizing inline model says not to drill one because its lines must remain closed. Where freezing is possible, that model’s head must be in a temperature-controlled enclosure.
These instructions apply to those particular models and configurations. Follow the manual for the exact pump rather than transferring a freeze-protection detail from a different design.
The Installation Must Preserve the Sanitary Well Seal
A hand pump becomes part of the drinking-water wellhead. It should not be fitted through a loose homemade cover. The EPA explains that a well cap keeps out debris, insects and small animals, while a pitless adapter provides a sanitary, frost-protected connection below grade. Pipe, rod, wire and vent penetrations must preserve that protection.
Requirements vary by jurisdiction. Wisconsin’s rule, for example, requires pump installations to protect against contamination and remain accessible for service. For shallow suction, deep-well piston and deep-well jet arrangements that do not otherwise seal the casing, it calls for a threaded fitting or an expandable rubber or neoprene gasket around piping emerging from the top (Wisconsin NR 812.32). That Wisconsin provision does not establish the rule in other jurisdictions.
Check state and local requirements before opening the well or replacing its cap. Follow the locally required disinfection and sampling procedure after installation or repair.
CDC recommends testing whenever any part of a well system is repaired or replaced, using a state-certified laboratory. It also recommends annual testing for total coliform bacteria, nitrates, total dissolved solids and pH, plus locally relevant contaminants identified with the health department (CDC).
