How to Install a Hand Pump on a Well

What You Need Before You Start

A hand pump sits on top of your well casing and draws water up through a pipe that reaches down into the water. Installing one means securing the pump to the casing, connecting the intake pipe, and priming the system so it pulls water instead of air. Most hand pumps bolt directly to a 2-inch or 4-inch well casing and take two to four hours to install if you have the right parts and tools on hand.

Before you buy a pump, measure your well casing diameter — the outside width of the pipe sticking up from the ground. Hand pumps come sized for specific casings: 2-inch, 4-inch, or 6-inch. You also need to know your static water level — how far down the water sits when the well is not being pumped. If water is more than 25 feet below the surface, a standard hand pump will not work; you need a deep-well model instead. You can find this depth by dropping a weighted string down the casing until it hits water, or by asking the previous owner or a well contractor.

Key Takeaways

Hand pumps work only if your water level is 25 feet or shallower; deeper wells need a deep-well pump with a longer pipe and different valve design.
The pump bolts to the top of your well casing, so you need the correct diameter size — measure your casing before ordering.
The intake pipe must reach below your lowest expected water level, and you prime the pump by pouring water down the top until it begins to draw from the well.
Leaks at the casing connection are the most common problem; use plumber's tape and a wrench to tighten the base bolts in a cross pattern.

Gather Your Tools and Materials

You will need an adjustable wrench or socket set, a level, plumber's tape (also called thread seal tape or PTFE tape), a hacksaw or pipe cutter, and a bucket for priming water. The hand pump kit should include the pump head, a base plate that matches your casing size, bolts, and gaskets. You will also need intake pipe — usually 1.25-inch galvanized steel or PVC — cut to reach from below your water level to the pump inlet, plus a foot valve (a one-way check valve) that screws onto the bottom end of the intake pipe to keep water from draining back down.

If your well casing is corroded or the threads are damaged, you may need a new casing adapter or coupling. Buy these before you start so you do not have to stop mid-installation. Gather everything on the ground next to the well so you do not have to hunt for parts while the pump is half-installed.

Prepare the Well Casing and Install the Base Plate

Turn off and lock out any electric pump if one is currently running. Remove any cap or cover on top of the casing. Clean the top of the casing with a wire brush to remove rust, dirt, or old sealant so the base plate gasket sits flush. If the casing threads are damaged or corroded, screw on a casing adapter first, then install the base plate onto the adapter.

Wrap plumber's tape clockwise around the casing threads three times — this fills small gaps and prevents leaks. Screw the base plate onto the casing by hand first, then use a wrench to tighten it snugly. Do not over-tighten; you want it firm enough that water cannot seep around the gasket, but not so tight that you crack the base plate. Use a level to check that the base plate is horizontal. If it tilts, water will pool on one side and the pump will not prime evenly.

Cut and Assemble the Intake Pipe

Measure the distance from the bottom of the base plate down to at least 3 feet below your static water level. Add 6 inches to this measurement — the extra length gives you a safety margin if the water level drops seasonally. Cut your intake pipe to this length using a hacksaw or pipe cutter. A clean, square cut matters; a jagged edge will not seal properly to the foot valve.

Screw the foot valve onto the bottom end of the intake pipe. Wrap the threads with plumber's tape first so the connection does not leak. The foot valve has a small flapper inside that lets water in but not out, so it matters which end faces down — the inlet (marked on the valve body) points downward into the well. Screw the top end of the intake pipe into the inlet port on the pump head, again using plumber's tape on the threads.

Lower the Intake Pipe and Bolt the Pump Head

Carefully lower the intake pipe down through the center of the base plate and into the well casing. It should slide down freely; if it binds or sticks, pull it back up and check for kinks or debris. Once the pipe is fully inserted, position the pump head on the base plate so the intake port aligns with the top of the pipe. The pump head should sit level and stable.

Insert the bolts through the base plate holes and into the threaded holes on the pump head. Tighten them in a cross pattern — if the pump has four bolts, tighten top, then bottom, then left, then right, then repeat. This distributes pressure evenly and prevents the gasket from pinching on one side. Tighten until snug, then give each bolt a quarter turn more. Check again with a level to make sure the pump head has not tilted.

Prime the Pump and Test for Leaks

Priming means filling the pump chamber and intake pipe with water so the pump can begin to draw from the well. Pour water slowly down the top opening of the pump — usually a 1-inch hole in the pump head — until water comes out the spout. This can take a gallon or more. Once water flows from the spout, begin pumping the handle slowly and steadily. After 10 to 20 strokes, the pump should begin to draw water from the well; you will feel the resistance increase and hear a change in the sound.

Watch the base plate and the connection where the intake pipe enters the pump head. If water drips from the base plate bolts, stop and tighten them another quarter turn. If water leaks from the intake pipe connection, turn off the pump, let it drain, and re-wrap the threads with plumber's tape, then retighten. Once the pump draws water smoothly and no leaks appear after five minutes of pumping, the installation is complete.

Troubleshooting Common Installation Problems

If the pump will not prime no matter how much water you pour in, the intake pipe may be cracked, the foot valve may be installed upside down, or the pipe may not reach the water. Pull the pump head off, remove the intake pipe, and inspect it for cracks or kinks. Reinstall the foot valve with the inlet facing downward, and measure again to confirm the pipe reaches below your water level.

If the pump primes but then loses prime after you stop pumping, the foot valve is leaking and water is draining back down the pipe. This usually means debris is stuck in the flapper. Remove the intake pipe, unscrew the foot valve, and rinse it under clean running water. Screw it back on and reinstall. If the problem persists, replace the foot valve — they are inexpensive and wear out over time.

If water leaks from under the base plate even after you tighten the bolts, the gasket may be damaged or the casing may be bent. Remove the pump head, inspect the gasket for cracks or flattening, and replace it if needed. If the casing is visibly dented, you may need a casing adapter to create a smooth surface for the gasket to seal against.

Frequently Asked Questions

Can I install a hand pump on a well that already has an electric pump?

Yes, but you need a sanitary seal or check valve to prevent the two pumps from interfering with each other. Most well contractors can install a tee fitting below the surface that lets both pumps draw from the same well. If you want to install the hand pump yourself, turn off the electric pump and cap its line before you begin.

What if my well casing is 6 inches wide instead of 2 or 4 inches?

Hand pumps are made for 2-inch, 4-inch, and 6-inch casings. Order the pump sized for your casing diameter. If your casing is an unusual size, a well contractor can install a reducer coupling to step it down to a standard size, then mount the pump on the reducer.

How deep can a hand pump pull water from?

Standard hand pumps work down to about 25 feet. Deep-well hand pumps use a longer pipe and a different valve design and can pull from depths of 30 to 50 feet, though they require more effort to operate. If your water level is deeper than 50 feet, a hand pump will not work; you need an electric submersible pump.

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

Permit requirements vary by county and state. Some areas require a permit for any work on a well; others do not. Contact your local health department or building department before you start to find out what rules explore in your area.

Can I use PVC pipe instead of galvanized steel for the intake pipe?

Yes, PVC works well for intake pipes and is lighter and easier to cut than galvanized steel. Use schedule 40 PVC rated for water, and glue all joints with PVC cement so they do not separate underground. Galvanized steel is more durable if you expect the well to be exposed to freezing temperatures or rough handling.
