Well Pump Installation & Replacement

Expert pump sizing, selection, and installation for Spokane-area wells.

When to Replace Your Well Pump

Well pumps typically last 10–20 years depending on usage, water quality, and maintenance. Here are signs it's time for a replacement rather than another repair:

  • Age — If your pump is 15+ years old and needing frequent repairs, replacement is usually more cost-effective
  • Escalating repair costs — When repair bills keep climbing, investing in a new pump saves money long-term
  • Decreased water flow — Gradual loss of pressure or flow that doesn't respond to repairs
  • Motor failure — Burned-out motors in deep wells often make full replacement the better option
  • Sand or sediment — Persistent sediment can indicate worn pump internals beyond repair
  • Constant cycling — If your pump cycles on and off constantly despite pressure tank service
  • Well modifications — Deepening a well or changing the casing may require a different pump configuration
  • Home upgrades — Adding bathrooms, irrigation systems, or a second dwelling may outgrow your current pump's capacity

Types of Pumps We Install

⬇️

Submersible Pumps

The most common type in the Spokane area. Installed deep inside the well casing, these reliable workhorses push water up to your pressure tank. Ideal for wells deeper than 25 feet.

💨

Jet Pumps

Mounted above ground, jet pumps use suction to draw water up. Available in shallow-well (up to 25 ft) and deep-well (up to 110 ft) configurations. Easy to service since they're accessible.

🔄

Constant Pressure (VFD) Systems

Variable Frequency Drive systems like the Grundfos CU 301 and Franklin SubDrive automatically adjust pump speed to maintain steady pressure throughout your home. Instead of the traditional on/off cycling, VFD systems ramp the motor up and down to match real-time demand — no more pressure drops when someone flushes while you're in the shower. These systems also reduce electrical costs and extend pump life by eliminating hard starts.

Booster Pumps

When your well produces enough water but you need more pressure at the house, a booster pump is the solution. We install inline and tank-style booster systems.

Our Sizing Process

Choosing the right pump matters — too small and you won't have enough water, too large and you waste energy and shorten pump life. We consider:

  • Well depth and static water level — determines how far the pump needs to push water
  • Well yield (GPM) — your pump should never exceed your well's production capacity
  • Household demand — number of bathrooms, fixtures, irrigation needs
  • Pipe size and distance — from well to pressure tank to house
  • Desired pressure — standard (30/50 PSI) or high-pressure (40/60 PSI) settings

Our Pump Sizing Process

Proper pump sizing is the most important part of any installation. An oversized pump wastes energy and can damage your well. An undersized pump won't keep up with demand. Here's our thorough approach:

Well Log Review

We start by pulling your well log from the Washington State Department of Ecology database. The well log tells us total depth, casing diameter, static water level, and the driller's estimated yield. This is the foundation for proper pump sizing — without it, we're guessing.

Household Demand Calculation

We evaluate your actual water usage needs based on the number of bathrooms, fixtures, appliances (dishwashers, washing machines), and any outdoor uses like irrigation or livestock. A 2-bathroom home typically needs 8–12 GPM, while a 4-bathroom home with irrigation might need 15–20 GPM or more.

Electrical Service Evaluation

Larger pumps (1 HP and above) require 240-volt service with appropriately sized breakers and wire gauge. We verify your electrical panel can support the recommended pump, and if upgrades are needed, we factor that into the quote. Running a large pump on undersized wire causes voltage drop, overheating, and premature motor failure.

Brands We Trust

We install top-quality pumps from manufacturers with proven track records in the Spokane area:

  • Grundfos — Premium Danish-engineered pumps known for efficiency and longevity. Their SQE series with CU 301 controller is our top recommendation for constant-pressure applications.
  • Franklin Electric — Industry-standard motors and controls with excellent reliability. The Franklin SubDrive constant-pressure system is a cost-effective VFD option we install frequently.
  • Goulds Water Technology — Trusted American manufacturer with a wide range of residential submersible pumps. Their GS series is a reliable workhorse for standard installations.
  • Myers — Affordable, dependable pumps with solid performance in residential wells. A good value choice when budget is a primary concern.

Installation Process

Assessment

We inspect your well, measure depth and water levels, check electrical capacity, and evaluate your household needs to recommend the right pump.

Quote & Scheduling

You get a detailed written quote covering the pump, materials, and labor. No hidden costs. We schedule installation at your convenience.

Old Pump Removal

Using our crane-equipped service truck, we pull the old pump and inspect the well casing, drop pipe, and wiring for any additional issues.

New Pump Installation

We install the new pump with fresh drop pipe, safety rope, wiring, and splice connections. Everything is done to code and built to last.

Testing & Handoff

We verify flow rate, pressure, and electrical draw. We walk you through your new system and make sure everything is running perfectly before we leave.
