What Is Form 22R — Well Inspection Addendum in Washington Real Estate?

Form 22R is the Well Inspection Addendum used in Washington real estate transactions when a property is served by a private well.

This addendum allows buyers to inspect the well system and test the water quality before completing the purchase. Because private wells are responsible for providing the home’s drinking water, buyers need to verify that the system is functioning properly and that the water meets safety standards.

Form 22R is typically attached to the Purchase and Sale Agreement (Form 21) and becomes part of the contract once mutual acceptance occurs.

Why the Well Inspection Addendum Is Used

Homes on private wells require additional due diligence compared to homes connected to municipal water systems.

Form 22R allows buyers to confirm:

  • the well produces sufficient water
  • the water quality is safe
  • the well system is functioning properly
  • the well complies with applicable regulations

Testing and inspection help prevent unexpected problems after closing.


What the Well Inspection Typically Includes

When Form 22R is included in the contract, buyers may conduct several types of inspections and tests.

Well production test

Measures how much water the well produces and whether it can supply the home reliably.

Water quality testing

Tests for contaminants such as bacteria, nitrates, and other water quality concerns.

Well equipment inspection

Evaluates components such as the pump, pressure tank, and other system parts.

These inspections help buyers understand the condition of the water system serving the home.


What Happens If Problems Are Found

If the well inspection reveals issues, the buyer may have options depending on the terms written in the addendum.

Possible outcomes include:

  • requesting repairs to the well system
  • requesting treatment or water system improvements
  • negotiating credits toward repairs
  • terminating the contract if major problems are discovered

These negotiations occur during the contingency period established in the addendum.


Why Well Inspections Are Important in Washington

Private wells are common in rural areas and some suburban parts of Washington, including portions of Snohomish County.

Unlike municipal water systems, the homeowner is responsible for maintaining the well and ensuring water quality.

Because of this, buyers should verify the well system is operating properly before closing on the property.


How Form 22R Fits Into the Inspection Process

The well inspection addendum often works alongside other due diligence steps such as:

  • general home inspection
  • septic inspection
  • sewer scope inspections (for homes connected to sewer)

These inspections help buyers fully evaluate the condition of the property before completing the purchase.
