RE: Request for Alternate Design Air Admittance Valve at 8534 Frederick Place
Dear Mr. Maciaszyk:
GARY HAAKENSON
MAYOR
The City is in receipt of your request for alternate design (reference building permit #2008-1018) for
installation of an air admittance valve serving the kitchen sink and dishwasher at the Gilham residence
at 8534 Frederick Place in Edmonds. Reasons for the alternate venting source include that existing
drains are above the floor system and are too high to accommodate a loop vent. There is also a
structural beam within the nearest adjacent wall that prevents vent piping to be run conventionally.
The request to use an air admittance valve in the location indicated is hereby approved with the noted
conditions below.
➢ Install per manufacturer's specifications
➢ Condition of approval of the alternate design request shall include that the plumbing contractor
provide the owner with written directions as to how to inspect and maintain the air admittance
valve for life. These directions shall be provided to all future homeowners.
Sincerely,
Leif Bjorback
Assistant Building Official
