Then there is what is under the yard. Olalla is a web of valleys and ridges running down to Colvos Passage. Olalla Creek drains a flat, wet valley floor; the ridges are glacial till with hardpan near the surface. Waterfront lots at the bay and Fragaria sit under steep clay bluffs. Water tables are high in the valleys, and the ridges shed runoff into crawlspaces every winter. From our shop in Port Orchard, Olalla is about 20 to 25 minutes south of Port Orchard on Highway 16 or down Banner Road; we schedule it alongside nearby stops so windows stay tight.
Why backflow preventer installation is a little different in Olalla
Newer homes in Olalla with residential fire sprinklers frequently have a double check assembly in the garage or crawlspace that nobody has looked at since the house was built. We inspect, test-coordinate and replace those when they fail.
Where the water comes from changes the diagnosis. Private wells dominate. There is no large water district in Olalla; a handful of small community well systems serve clusters of homes near the bay and along Banner Road, and nearly everything else draws from its own well.

Backflow Preventer Installation questions from Olalla
Is a permit needed to install a backflow preventer in Olalla?
Usually a plumbing permit is required, and the purveyor needs the installation and test report. We take care of both as part of the job.
Which water districts in Olalla require backflow preventers?
Every public water purveyor serving Olalla runs a cross-connection program under Washington's drinking water rules. If you have irrigation, fire sprinklers, a boiler or a well on the property, expect a requirement.
How quickly can you install a backflow device in Olalla?
Most residential assemblies are installed within a few days of approving the quote, and we carry common PVB and double check sizes on the truck. RPZs for commercial services may need to be ordered.
My backflow test failed in Olalla. Do I have to replace the device?
Not always. If the body is sound we rebuild it with new checks and springs, which is far less than replacement. If the body is pitted or the shutoffs are gone, we recommend a new assembly and show you why.
Can a backflow preventer be installed underground?
A double check valve assembly can be, in a proper vault with drainage. Pressure vacuum breakers and RPZs cannot; they need to be above grade, and the PVB has to sit above the highest sprinkler head it serves.
From Port Orchard it is an easy run to Olalla, and we keep the trucks stocked so a repair rarely waits on a parts run. Water heaters, valves, pumps and fittings for the common jobs ride with us.
