# Well Inspection Before Buying a Home in Spokane: What Every Buyer Needs to Know

Buying a home with a private well in the Spokane area? Congratulations — you're joining thousands of homeowners across Spokane County, Spokane Valley, and the surrounding communities who enjoy clean, independent water from their own well. But before you sign on that dotted line, there's one critical step many buyers overlook: a thorough well inspection.

Skipping a well inspection before purchasing a home can lead to thousands of dollars in unexpected repairs, health risks from contaminated water, and serious headaches down the road. In this guide, we'll walk you through exactly what a well inspection involves, why it matters in the Spokane area, what Washington state law requires, and how to protect your investment.

Why a Well Inspection Is Essential Before Buying a Home

When a home is on city water, the municipal system handles water quality and delivery. With a private well, you are responsible for everything — the well itself, the pump, the pressure tank, the piping, and the water quality.

A home inspection alone won't cut it. Most general home inspectors aren't equipped to evaluate well systems. They'll note that the water turns on and off, but they won't tell you:

  • Whether the well produces enough water for your household
  • If the pump is near the end of its lifespan
  • Whether the water contains bacteria, nitrates, arsenic, or other contaminants common in Spokane County
  • If the well complies with Washington state regulations

That's why a dedicated well inspection is worth every penny — and in many cases, it's required.

What Does a Well Inspection Include?

A comprehensive well inspection for a real estate transaction in the Spokane area should cover several key areas:

1. Visual Inspection of the Well and Components

A qualified technician will examine:

  • **The wellhead and casing:** Is it properly sealed? Is the cap secure? Are there signs of damage, corrosion, or improper sealing that could allow surface water contamination?
  • **The pressure tank:** Is it waterlogged or functioning correctly? Pressure tanks typically last 10–15 years.
  • **Electrical connections:** Are the wiring, control box, and breaker properly installed and up to code?
  • **The pump system:** What type of pump is installed (submersible or jet pump), and what condition is it in?

2. Flow Rate Testing (4-Hour Flow Test)

One of the most important parts of a well inspection is the 4-hour flow test, also called a well yield test. This measures how many gallons per minute (GPM) your well produces over an extended period.

In Washington state, the Department of Ecology generally considers a minimum of 1 GPM adequate for a single-family home (that's about 1,440 gallons per day). However, most Spokane-area households need closer to 3–5 GPM for comfortable daily use — showers, laundry, irrigation, and more.

A 4-hour flow test reveals:

  • **Sustained yield:** Can the well keep up with demand, or does it run dry during peak usage?
  • **Recovery rate:** How quickly does the well recharge after heavy pumping?
  • **Drawdown levels:** How far does the water level drop during pumping?

If the flow rate is too low, you may need a storage tank system, a deeper well, or you may want to reconsider the purchase entirely.

3. Water Quality Testing

Water quality testing checks for contaminants that can affect your health and your home. In the Spokane area, common concerns include:

  • **Coliform bacteria and E. coli:** Indicates possible contamination from surface water, septic systems, or animal waste
  • **Nitrates:** Especially important if the property is near agricultural land — dangerous for infants and pregnant women
  • **Arsenic:** Naturally occurring in some Spokane County geological formations
  • **Iron and manganese:** Won't make you sick but cause staining, bad taste, and plumbing buildup
  • **Hardness:** Spokane well water tends to be moderately hard, which can affect appliances and plumbing
  • **pH levels:** Water that's too acidic or alkaline can corrode pipes and fixtures

At minimum, test for coliform bacteria, nitrates, arsenic, and basic minerals. Your lender may require specific tests as a condition of financing.

Washington State Law and Well Requirements (RCW 18.104)

Washington state regulates private wells under RCW 18.104 (Water Well Construction Act) and WAC 173-160 (Minimum Standards for Construction and Maintenance of Wells).

Here's what buyers need to know:

  • **Well logs:** Every well drilled in Washington should have a well log filed with the Department of Ecology. This document records the well's depth, casing, geology, and original yield. Ask the seller for a copy, or search the [Department of Ecology well log database](https://apps.ecology.wa.gov/welllog/).
  • **Decommissioning:** If the property has any abandoned or unused wells, Washington law requires they be properly decommissioned (sealed) by a licensed well driller. Unsealed wells are a contamination risk and a safety hazard.
  • **Setback requirements:** Wells must be a minimum distance from septic systems, property lines, and potential contamination sources. If these setbacks aren't met, it could affect your ability to get financing or insurance.

How Much Does a Well Inspection Cost in Spokane?

Well inspection costs in the Spokane area vary depending on what's included:

| Service | Typical Cost | |---------|-------------| | Basic visual inspection | $150–$300 | | 4-hour flow test | $400–$600 | | Water quality testing (basic panel) | $100–$250 | | Comprehensive inspection (all of the above) | $500–$1,000 |

Compare that to the cost of replacing a well pump ($1,500–$4,000+), drilling a new well ($8,000–$15,000+), or dealing with contaminated water. A few hundred dollars upfront is cheap insurance.

Red Flags to Watch For

During the inspection process, watch for these warning signs:

  • **No well log on file:** Could indicate an older, unpermitted well with unknown depth and construction
  • **Well casing above ground is damaged, cracked, or missing a cap:** Easy entry point for contamination
  • **Low flow rate (under 1 GPM):** May not support a household, especially during Spokane's dry summers
  • **Bacteria present in water test:** Indicates contamination — may be fixable with shock chlorination, but could signal a bigger problem
  • **Old or undersized pressure tank:** A waterlogged tank means the pump cycles on and off too frequently, shortening its life
  • **Pump age over 15 years:** Submersible pumps typically last 15–25 years, but a pump nearing the end of its life means a replacement is coming soon
  • **Well located too close to septic system:** Minimum setback is typically 100 feet in Washington — violations are a serious concern

Tips for Spokane Home Buyers with Wells

1. Don't waive the well inspection. In competitive markets, buyers sometimes waive inspections to make their offer more attractive. With a well, this is a gamble you don't want to take.

2. Hire a licensed well professional, not just a home inspector. A licensed pump installer or well driller has the specialized knowledge to evaluate the entire system. In Washington, well work requires a license under RCW 18.104.

3. Request well records from the seller. Ask for the well log, any maintenance records, pump installation dates, and previous water quality tests. Good records are a great sign.

4. Factor repair costs into your offer. If the inspection reveals an aging pump or marginal flow rate, negotiate the purchase price or request repairs before closing.

5. Test water quality annually after purchase. Even if the water tests clean at closing, conditions can change. The Washington Department of Health recommends annual testing for coliform bacteria and nitrates at minimum.

6. Get a second opinion if something seems off. If the seller's provided flow test or water quality results don't match your inspector's findings, dig deeper.

When to Walk Away

Not every well problem is a deal-breaker, but some situations warrant serious reconsideration:

  • The well produces less than 0.5 GPM with no practical storage solution
  • Water quality tests reveal persistent contamination that can't be remediated cost-effectively
  • The well is unpermitted, improperly constructed, or violates setback requirements
  • Drilling a new well would be required and the lot conditions make it impractical or extremely expensive
