Why Burien leak repair calls look the way they do
Hot tub leaks in Burien are almost never the shell. They are a pump seal, a union o-ring, a heater gasket, a jet body or a glued joint buried in foam, and locating the leak is most of the work. We start in the equipment bay and move outward only when the bay is dry.
Three Tree Point and Seahurst take salt wind off the Sound and we check heater terminals for corrosion first; inland Burien tubs mostly fight shade, needles and damp cabinets. A cabinet that is always damp in Burien hides a slow leak for months; we pull the panels on every side and dry the bay before trusting what we see.
The tubs are mid-age family spas — Hot Spring, Sundance, Cal Spas, Master Spas — plus a run of older tubs on the White Center side that have been repaired piecemeal by several owners. We work Seahurst, Gregory Heights, Three Tree Point, Lake Burien, Boulevard Park and the rest of Burien (98146, 98148, 98166).
What Burien owners describe on the phone
Soaked foam, no obvious source
A jet body or a glued joint inside the insulation. Moisture meter and dye find it; we cut only what is needed.
Leaks only when the jets run
Pressure-side plumbing: a jet gasket, a diverter or a cracked manifold. The tub holds water at rest and loses it under pressure.
Level drops an inch or more a week
Past evaporation. We tape the level, confirm the loss, then isolate: pump off versus pump on tells us suction side or pressure side.
Wet floor inside the equipment door
Pump shaft seal, union o-ring or heater manifold gasket — all same-visit repairs with parts off the van.
Burien note. On a waterfront lot a dab of dielectric grease on the heater terminals at every service visit slows the salt corrosion that mimics a failed element on the meter.
How the visit runs
- A call half an hour before we arrive — about 18 minutes south of downtown via SR 509 or Highway 99
- Diagnosis with a meter, then one written price you approve
- Calcium and alkalinity checked for Highline Water District and Seattle Public Utilities water
- Special-order parts arrive the next business day in most cases
- If the tub is not worth fixing, we say so
Scope, plainly: the spa and what lives inside its skirt. New circuits, supply plumbing and setting new tubs go to an electrician or a dealer.
