Port Townsend: Water Pressure Dropped and Nobody Knows Why

Why this happens in Port Townsend

The most common cause we find in Port Townsend is a leak on the service line. Water leaving the pipe underground never reaches the house. On mid-century grid lots on Sheridan Street with till toward Discovery Bay underneath, that's where we look first.

We also check a partially closed or failing valve, because in Port Townsend it explains a real share of low water pressure calls. A main shutoff that was never fully reopened, or a gate valve whose gate has dropped.

Don't overlook a pressure regulator or well pressure switch. On a regulated system or a well, the regulator or the switch can fail. On Port Townsend properties from an 1880s Victorian seaport ringed by mid-century neighborhoods it comes up more than you'd think.

Before you call

In Port Townsend's Uptown and Downtown historic districts the service line may be a century old and its route unknown, so tracing comes first.

Before we arrive in Port Townsend, three things you can do: check whether the pressure is low at every fixture or just one. Look at the pipe at the point of entry: threaded gray steel means galvanized. Do the meter test with the house isolated. None of it requires tools, and all of it helps us repair, if you want us to faster on waterfront near Point Hudson.

What happens next

Fixing low water pressure here usually ends with underground water leak detection near Fort Worden: repair, if you want us to with electronic acoustic ground microphone, listen on small Victorian lots in Uptown, trace the line. One crew, one visit, outwash sand under the historic districts put back the way it was.

We've handled low water pressure near Water Street where the cause was poly on the Cape George parcels, and near Kah Tai Lagoon where clay seams in the uplands was hiding a drain failure. A dedicated trip across the Hood Canal Bridge; we schedule Port Townsend so you aren't waiting a whole day.
