What You Need Before You Start

A hand pump water well installation requires the pump itself, a well casing (the pipe that goes into the ground), a foot valve at the bottom, and basic tools like a wrench, pipe tape, and a shovel. You will also need to know your water table depth — how far down the water sits in your area. Most hand pumps work best when the water is 25 feet down or less, though some models reach deeper. Contact your local water authority or a well driller to find out your area's typical depth before you buy.

The pump connects to the casing at ground level, so you need to decide whether to install the casing yourself or hire a well driller to bore the hole and set it. Drilling costs money but saves weeks of labor and ensures the hole is straight and sealed properly. If you drill yourself, you will need a hand auger (a manual drilling tool) for shallow wells or a power auger for anything deeper than 15 feet. Hand augers work for clay and sandy soil but struggle in rock or very hard ground.

Key Takeaways

  • Hand pumps work best when groundwater is 25 feet down or less; check your local water table depth before purchasing equipment.
  • The well casing must be sealed at the top and bottom to prevent contamination, and the foot valve at the bottom keeps water from draining back out.
  • Priming the pump — filling it with water before first use — is essential; without it, the pump will not draw water up from below.
  • Test the water quality through your local health department before drinking it, because hand-dug wells can pick up bacteria or minerals from surrounding soil.
  • A hand pump requires regular maintenance: check seals yearly, replace worn leather cups every few years, and keep the pump head covered when not in use.

Drilling or Boring the Well Hole

If you hire a well driller, they will bore a hole 4 to 6 inches wide down to the water table, then lower a casing (usually PVC or steel pipe) into it. The driller will seal the space between the casing and the surrounding soil with bentonite clay or grout to stop surface water from seeping down and contaminating your well. This takes one to three days and costs between $1,500 and $3,000 depending on depth and soil type, but it is the safest route for most homeowners.

If you drill by hand, start with a hand auger for wells under 15 feet deep. Augers work by twisting into the soil and pulling it up in sections. You add extensions to the handle as you go deeper. For depths between 15 and 25 feet, rent a power auger from a tool rental shop — these are gasoline-powered and much faster, though they require two people to operate safely. Stop drilling when you hit water or when the auger becomes too hard to turn, whichever comes first.

Once the hole reaches the water table, lower your casing into it carefully. The casing should extend at least 12 inches above ground level so surface water cannot run down into it. If there is a gap between the casing and the soil, fill it with bentonite clay or concrete grout, working from the bottom up. This seal is critical — without it, contaminated surface water will flow straight into your well.

Installing the Foot Valve and Strainer

The foot valve sits at the bottom of the casing inside the well and acts like a one-way door: it lets water flow up into the pump but stops it from draining back down when the pump is not running. Without a foot valve, you would have to prime (refill) the pump every time you use it. Foot valves come in two types: flapper valves (simpler, cheaper, prone to sticking) and ball valves (more reliable, last longer). For a hand pump, a ball-type foot valve is worth the extra cost.

Attach the foot valve to the bottom of your intake pipe — the pipe that runs from the pump down into the well. The intake pipe is usually 1.5 or 2 inches in diameter and connects to the pump at the top. Wrap the threads with plumber's tape (also called PTFE tape) before screwing the foot valve on; this prevents leaks. The strainer — a small screen that keeps sediment out — sits just above the foot valve and should be cleaned or replaced every year or two, depending on how much sediment your well produces.

Connecting the Pump to the Casing

The hand pump mounts on top of the casing at ground level. Most hand pumps bolt to a flange (a flat metal ring) that you attach to the top of the casing. First, cut the casing to the right height — usually 12 to 18 inches above ground — using a hacksaw or reciprocating saw. File down any sharp edges. Screw the flange onto the top of the casing, using plumber's tape on the threads again.

Lower the intake pipe with the foot valve attached down through the center of the casing until the foot valve reaches the bottom or sits just above the sediment layer. The intake pipe should be rigid enough not to bend under its own weight; PVC works for shallow wells, but steel or galvanized pipe is better for deeper ones. Bolt the pump to the flange, making sure it is level and tight. Tighten all bolts in a cross pattern (opposite sides alternately) so the pump sits evenly.

Connect the pump handle to the pump head according to the manufacturer's instructions — different pump models attach differently. Some use a pin and cotter key, others use bolts. Make sure the handle moves freely and does not bind at the top or bottom of its stroke.

Priming the Pump and Testing for Water

Priming means filling the pump chamber and intake pipe with water so the pump can create suction and draw water up from the well. Without priming, the pump will just move air and produce nothing. Pour water down the top of the pump (most pumps have a priming hole or you can pour it down the handle hole) until water comes out the spout. Then work the handle up and down slowly — about one stroke per second — for 30 to 60 seconds. You should feel resistance building as the pump creates suction. When water starts flowing from the spout, you have primed successfully.

Once water flows, pump for at least five minutes to clear air from the system and flush out any sediment or debris from the well. The water may be cloudy or discolored at first; this is normal. Keep pumping until it runs clear. If the pump stops producing water after a few minutes, it has lost its prime — this usually means air is leaking into the intake pipe, often at a loose connection. Check all threaded joints, tighten them, and prime again.

Before you drink the water, send a sample to your local health department or a certified water testing lab. Hand-dug wells can contain bacteria, nitrates, or minerals that make water unsafe. Testing costs $25 to $100 and takes one to two weeks. Do not skip this step — it is the only way to know if your well is safe.

Sealing and Protecting the Well

A well that is not sealed properly invites contamination. The top of the casing should be sealed with a sanitary well cap — a metal or plastic cover that keeps insects, leaves, and surface water out while allowing the pump to operate. The cap should fit snugly and have a vent hole to prevent pressure buildup. If you are not using the pump regularly, keep the cap on and sealed.

Build a small platform or pad around the base of the pump to keep standing water from pooling there. Concrete works well and also keeps the ground stable. Make sure the ground slopes away from the well so rain runs off rather than pooling. If you live in a cold climate, insulate the pump head and the top of the casing to prevent freezing; a foam insulation jacket designed for pumps works well and costs $30 to $60.

Maintenance and Troubleshooting

Hand pumps are straightforward machines, but they need regular care. Check the pump seal (the rubber or leather gasket that keeps water from leaking out around the handle) once a year. If water drips from the seal when you pump, the seal is worn and needs replacement — this is a $20 to $50 part and takes 15 minutes to swap out. Leather cups inside the pump wear out over time and should be replaced every three to five years, depending on use. Replacement kits are available from pump manufacturers and cost $30 to $80.

If the pump stops producing water, first check that the intake pipe has not come loose at the bottom of the well — this is rare but happens if the casing shifts. More often, the foot valve is stuck or clogged. Try priming again and pumping vigorously for a minute. If that does not work, you may need to pull the intake pipe up and clean or replace the foot valve. If the pump leaks from the base where it bolts to the flange, tighten the bolts in a cross pattern. If it still leaks, the flange gasket may be worn and need replacement.

In winter, if you live where temperatures drop below freezing, drain the pump after each use by opening a small drain valve at the base (if your pump has one) or by pumping until no more water comes out. Water left in the pump will freeze and crack the pump head. Some people wrap the pump in blankets or move it indoors during winter, though this is only practical for very small pumps.

Frequently Asked Questions

How deep can a hand pump pull water from?

Most hand pumps work reliably down to 25 feet. Some models are rated to 30 feet, but pulling from that depth requires more effort and is harder on the pump. If your water table is deeper than 25 feet, a hand pump will be exhausting to use daily, and a small electric pump may be a better choice.

Can I install a hand pump on an existing well?

Yes, if the existing well casing is in good condition and the water is within 25 feet of the surface. You will need to remove the old pump, clean the casing, install a new foot valve and intake pipe, and mount the hand pump on top. Have the water tested before you start, since you do not know the history of the old well.

What if my well runs dry in summer?

A dry well usually means the water table dropped below your intake pipe. This happens in drought years or in areas with seasonal water tables. You can lower the intake pipe deeper into the casing if there is room, or drill a new, deeper well. Some people install a small storage tank to catch water during wet months and use it during dry ones.

Do I need a permit to install a hand pump well?

Most places require a permit for any new well, even a hand pump. Contact your county health department or water authority before you start. They will tell you the rules for your area, which may include setback distances from septic systems, testing requirements, and casing standards. Permits usually cost $50 to $200 and take one to four weeks.

How often should I have the water tested?

Test the water once before you start using it regularly. After that, test it once a year or whenever the water looks, smells, or tastes different. If you notice changes — cloudiness, rust color, or a sulfur smell — test when ready. Your local health department can tell you which tests are required in your area.
