Choosing the Right Pump for Your Water Storage Tank: A Simple Guide

A water storage tank is a great way to keep water handy. But you need a good pump to move that water where you need it. This guide helps you pick the best pump for your tank.

Key Features to Look For

When shopping for a water storage tank pump, several features really matter. These features help the pump work well for a long time.

1. Pump Type

  • Submersible Pumps: These pumps sit right inside your water tank. They push water up. They are usually quiet.
  • Jet Pumps (or External Pumps): These pumps sit outside the tank. They pull water out. They work well if the tank is underground or far away.

2. Flow Rate (GPM)

Flow rate means how much water the pump moves per minute (Gallons Per Minute or GPM). Think about how much water you need all at once. A bigger house or more sprinklers need a higher GPM.

3. Head Height (Lift)

Head height is how high the pump must push the water. Measure from the water level in the tank up to the highest point where the water will end up (like a faucet or sprinkler head). A taller distance needs a stronger pump.

4. Pressure Switch

A good pump has an automatic pressure switch. This switch turns the pump on when you open a faucet and turns it off when you close it. This saves energy and stops the pump from running too much.

Important Materials Matter

The materials the pump is made from affect how long it lasts and how safe the water stays.

Housing and Internals
  • Stainless Steel: This metal is very strong and resists rust. Pumps made with stainless steel last much longer.
  • Durable Plastics: Some parts use strong plastics. Make sure these plastics are rated for safe drinking water if you use the tank for that purpose.
Seals and Gaskets

Look for strong rubber or synthetic seals. Good seals stop leaks and keep dirt out of the pump mechanism. Leaks reduce the pump’s efficiency.

Factors That Change Pump Quality

Some things make a pump better, and some things can hurt it.

What Improves Quality:

  • Motor Quality: A reliable, well-known motor brand usually means better performance. Look for pumps with thermal overload protection. This stops the motor from burning out if it gets too hot.
  • Efficiency Ratings: Pumps with high efficiency ratings use less electricity to move the same amount of water.

What Reduces Quality:

  • Running Dry: Never let a pump run when the tank is empty. This is called “running dry.” It quickly ruins the pump’s seals and motor. Always check the water level!
  • Sediment: If your water tank has a lot of dirt or sand at the bottom, it can scratch the pump’s internal parts. Submersible pumps should sit slightly above the tank floor, or you need a pump designed to handle solids.

User Experience and Use Cases

How you plan to use the pump changes what you should buy.

Simple Home Use (Backup Water)

If you only need water for toilets or a few sinks during a power outage, a smaller, simpler jet pump might be enough. Quiet operation is a bonus here.

Lawn and Garden Irrigation

Sprinklers need high flow (GPM). You need a pump that can handle running for long periods without overheating. Look for a high GPM rating.

Deep Wells vs. Storage Tanks

Remember, pumps designed for deep wells are different from those for shallow storage tanks. Most storage tank pumps are designed for shallow lifts (less than 25 feet of suction). Always match the pump to the job.


10 Frequently Asked Questions (FAQ) About Water Storage Tank Pumps

Q: How deep can a jet pump pull water from the tank?

A: Standard jet pumps can effectively pull water from about 25 feet below the pump itself. If your tank is deeper than that, you need a true submersible pump.

Q: Do I need a pressure tank with my storage pump?

A: Yes, usually. A pressure tank stores pressurized water. This stops your pump from turning on and off every time you use a small amount of water, which makes the pump last longer.

Q: What is the difference between PSI and Head Height?

A: Head Height is how high the pump pushes water vertically. PSI (Pounds per Square Inch) is the force or pressure the water comes out with. They are related, but Head Height is the physical lift distance.

Q: How loud are submersible pumps compared to jet pumps?

A: Submersible pumps are much quieter because they are underwater. Jet pumps make noise because they run above ground, and you hear the motor working.

Q: Can I use a pump rated for irrigation to pump drinking water?

A: Only if the pump is specifically rated as “potable water safe.” Some pumps use materials that are not safe for drinking water.

Q: How often should I check my pump?

A: Check the tank water level often to prevent running dry. Annually, check the electrical connections and listen for strange noises.

Q: My pump cycles on and off quickly. What is wrong?

A: This usually means the air bladder inside your pressure tank is bad, or the pressure switch needs adjustment. The pump thinks the pressure dropped too fast.

Q: Which material resists hard water buildup best?

A: Stainless steel components handle mineral buildup better than cast iron, which can rust more easily.

Q: What size wire should I use for a new pump?

A: This depends entirely on the pump’s horsepower (HP) and the distance from your breaker box. Always follow the specific wire gauge recommendations listed in the pump’s manual.

Q: How do I winterize my external (jet) pump?

A: You must completely drain all water from the pump housing and pipes before freezing weather arrives. Water left inside will freeze and crack the pump body.
