Somerset housing profile
Primarily single-family construction from the early 1980s through mid-1990s, built on the slopes of Cougar Mountain. Many homes are on concrete slabs rather than crawlspaces, which means underground supply lines and unique freeze/leak profiles.
Common plumbing issues in Somerset
- Slab leaks in copper supply lines. 1980s-90s under-slab copper is at the 30-40 year mark where pinhole leaks appear.
- Polybutylene supply line failures. Some Somerset construction from the 1980s used polybutylene; chlorine degradation causes premature failure.
- High static water pressure (100+ psi). Hilltop elevation produces pressure that wears fixtures, fails washer hoses, and bursts toilet supply lines.
- Pressure-reducing valve failures. PRVs installed in the original construction are now 30+ years old and failing — pressure spikes to 110+ psi.
About working in Somerset
Somerset's plumbing profile is shaped by two factors: elevation and construction era. Most homes were built between 1980 and 1995 on slab foundations, which means supply lines run under concrete rather than through accessible crawlspaces. Slab leaks in this era's copper supply lines are the most common major repair we do in Somerset, typically diagnosed with acoustic and thermal imaging through our leak detection and pipe repair in Bellevue service before any concrete is cut. The second factor is elevation: static water pressure at hilltop addresses can exceed 100 psi, well above the 80-psi threshold where fixtures start failing prematurely — and Bellevue's source-water pH adjustment (covered in our where Bellevue's water comes from guide) is calibrated for typical 55-65 psi delivered pressure, so high-pressure homes wear out internal seals faster too. A whole-house pressure-reducing valve is essential equipment in Upper Somerset, and any 30+ year old original PRV is past its service life and likely failing.
