Well Pumps and Pressure Tanks

What Are Well Pumps and Pressure Tanks?

Cleanflow stocks a complete range of well pumps, pressure tanks, booster pumps, and well system accessories, everything you need to design, install, or service a well water system. A well pump and pressure tank work together to deliver consistent water pressure: the pump draws water from your well, and the pressure tank stores it under pressure to regulate flow and reduce pump cycling. Booster pumps add pressure for multi-storey buildings, long supply runs, or high-demand applications. Pitless adapters, pressure switches, gauges, and union tank tees complete the system.

Well Pump

The well pump is responsible for lifting water from the underground well. It supplies water either directly to the plumbing system or to a pressure tank. Proper sizing based on depth and demand is essential to ensure reliability and efficiency.

Booster Pump

If the water pressure delivered by the well pump is insufficient, especially in multi-storey buildings, a booster pump is used to increase pressure. It ensures adequate flow across all outlets, particularly on upper floors. Booster pumps are most effective when used in tandem with pressure tanks to prevent constant cycling and premature wear.

Pressure Tank

A pressure tank stores water under pressure and reduces the frequency of pump activation. This not only extends the lifespan of both the well and booster pumps but also ensures consistent pressure during peak demand. Accessories like pressure switches, gauges, and pitless adapters support optimal system performance and maintenance.

How to Size a Well Pump and Pressure Tank for Your Property

Sizing a well pump and pressure tank correctly matters more than the brand you choose. An undersized system cycles too often (shortening pump life), and an oversized system wastes money. Four variables determine the right setup:

1. Household Demand (peak GPM)

Count fixtures: each bathroom, kitchen sink, washing machine, and outdoor hose bib draws roughly 2-3 GPM at peak. A 3-bedroom, 2-bathroom home typically needs 8-12 GPM at peak demand. Larger properties with multiple bathrooms, irrigation systems, or livestock can need 15-20+ GPM. Match this to the well pump's rated GPM output.

2. Well Depth and Static Water Level

Wells under 25 feet typically use shallow well jet pumps (Flotec FP4105 series, for example). Wells from 25-90 feet often use convertible jet pumps configured for deep-well use. Wells over 90 feet require submersible pumps installed below the water level. Franklin Electric and Flotec submersibles are the dominant options. The well's static water level (depth to the top of the water column) determines submersion requirements.

3. Pressure Tank Capacity (drawdown gallons)

Pressure tank capacity is rated by total volume, but the working capacity, the drawdown, is what matters. A 20-gallon tank typically delivers 5-7 gallons of drawdown between pump cycles. For a 10 GPM pump, you want 1 gallon of drawdown per GPM minimum (so 10+ gallons of drawdown, ~30 gallon tank). The Flexcon Well-Rite WR-60R (20 gal) suits typical 3-bedroom homes; the WR-140R (44 gal) covers larger households or higher-demand systems.

4. Pressure Switch Settings

Most residential systems use a 30/50 PSI switch (pump turns on at 30 PSI, off at 50). Higher-pressure setups (40/60 or 50/70 PSI) suit multi-storey homes or longer plumbing runs. The pressure tank's pre-charge pressure must match the switch's cut-in setting, minus 2 PSI.

How to Drain a Pressure Tank

Draining a pressure tank is a routine maintenance task done before checking the air pre-charge, replacing a faulty bladder, or winterizing a well system. Here's the safe procedure for a typical pre-charged residential pressure tank:

Step 1: Turn off the power to the well pump

Switch off the breaker that powers the well pump at your main electrical panel. Do not skip this step. Running the pump against a closed system or empty tank can damage the motor.

Step 2: Close the supply valve from the pump

Locate the shutoff valve between the pump and the pressure tank, and close it. This isolates the tank from the well system.

Step 3: Open a fixture or the tank's drain valve to relieve pressure

Open the nearest hot or cold water fixture (a hose bib works well) and let the system drain. The pressure gauge on the tank should drop to 0 PSI. If your tank has a dedicated drain port, open it as well. Most pressure tanks have a hose bib threaded fitting at the base.

Step 4: Check the air pre-charge with a tire gauge

With the tank fully drained and at 0 PSI water pressure, remove the cap on the air valve at the top of the tank (it looks like a tire valve). Use a tire pressure gauge to read the air pre-charge. The reading should be 2 PSI below your pressure switch's cut-in setting for a 30/50 PSI switch; the pre-charge should read 28 PSI.

Step 5: Adjust pre-charge if needed, then refill

If the pre-charge is low, add air with a bicycle pump or compressor. If high, release air with the valve. Once correct, close the drain valve, close any open fixtures, restore power to the pump, and re-open the supply valve. The tank will refill and pressurize automatically.

If the tank won't hold pre-charge pressure, the bladder or diaphragm has likely failed, and the tank needs replacement. Cleanflow stocks Flexcon Well-Rite, Flotec, Franklin Electric, and WellMate replacement tanks in sizes from 2 to 119 gallons. For waterlogged or chronically-cycling systems, contact our team. We'll diagnose whether you need a new tank, a new pressure switch, or a system rebuild.

Choosing the Right Brand for Your Well System

Cleanflow stocks five major well-system brands. Each has a strength worth knowing before you buy:

Brand	Strength
Flexcon Well-Rite	Canadian market leader for pressure tanks; CAD-2 diaphragm technology since the late 1980s
Flotec (Pentair)	Most widely-stocked retail pump brand in North America; complete jet/booster/submersible range
Franklin Electric	Invented the modern submersible motor in 1950; global leader in submersible technology
WellMate	Composite (fiberglass-wrapped) pressure tanks — corrosion-immune, lighter weight
Red Lion	Patented Leak Safe Technology; budget-friendly with a strong residential warranty

Most well-system installers pair brands rather than building a single-brand system: a Flexcon Well-Rite pressure tank with a Flotec or Franklin Electric pump is the most common North American configuration. Cleanflow's accessory inventory, Plumb-Eeze pitless adapters, pressure switches, foot valves, and union tank tees, is brand-agnostic and works across the major pump-and-tank combinations.

How long do well pumps and pressure tanks typically last?

Well pumps and pressure tanks typically last 10–25 years, depending on maintenance, usage, and water quality.

Can well pumps and pressure tanks be installed in any well?

Yes, but the system type must suit the well’s depth and flow rate. A professional assessment is recommended to ensure proper sizing and performance.

Are well pumps and pressure tanks energy-efficient?

Yes. When properly sized and maintained, well pumps and pressure tanks are energy-efficient. Variable Frequency Drive (VFD) systems can further improve efficiency.

Can well pumps and pressure tanks handle high water demand?

Yes. As long as the system is correctly sized for your household or property’s water usage, it can handle high demand reliably.

Can well pumps and pressure tanks work with water treatment systems?

Absolutely. Well pumps and pressure tanks integrate seamlessly with filtration, softening, and water purification systems for complete water solutions.

What size pressure tank do I need for my well system?

As a general rule, choose 1 gallon of drawdown capacity per GPM of pump output. Most 10 GPM residential pumps pair well with a 30-44 gallon tank. Drawdown is typically 25-30% of total tank volume, so a 20-gallon tank delivers about 5-7 gallons of working capacity. For specific recommendations, contact our team with your pump GPM and household demand.

What's the difference between Flexcon, Flotec, and Franklin Electric pumps and tanks?

Flexcon Well-Rite is the Canadian market leader for pressure tanks. Flotec (a Pentair brand) covers residential jet, booster, and submersible pumps. Franklin Electric invented the modern submersible motor in 1950 and is the standard for deep-well applications over 90 feet.

Can I install a well pump and pressure tank myself, or do I need a licensed professional?

Pressure tank replacement is generally DIY-feasible on an existing system. Well pump replacement is more complex: submersible pump replacement typically requires a licensed well contractor with pulling equipment, since the existing pump must be lifted from 100+ feet of well casing. Send us a photo of your setup if you're unsure. We'll tell you honestly whether the job is DIY-feasible.
