Appeal Information Sheet

Appeal item 1

Code Section

710.1

Requires

710.1 Backflow Protection.
Fixtures installed on a floor level that is lower than the next upstream manhole cover of the public or private sewer shall be protected from backflow of sewage by installing an approved type of backwater valve.

Code Modification or Alternate Requested

Install a whole home backwater valve on the main sewer line at the basement bathroom group.

Proposed Design

Install an accessible backwater valve on the sewer main in the home's basement that is easily visible and accessible.

Reason for alternative

A whole home backwater valve is the most viable option for the homeowners as individual backwater valves for fixtures would require excessive modification to the finished tile floor, tile bath walls, plumbing, fixtures surrounding main lines, and foundation in multiple places.

Appeal Decision

Whole house backwater valve in lieu of backwater valve serving lower level fixtures only: Denied. Proposal does not provide equivalent sanitation.
Appellant may contact Kris Gutierrez (503-823-8630) with questions.
