Plumbing Engineered for Belmont Hills & Coastal Plain Geology
Located right in the heart of San Mateo County, Belmont transitions from the industrial flatlands along Old County Road and Marine View Avenue up through winding residential hillside neighborhoods including San Juan Canyon, Hallmark, Carlmont, Cipriani, and Belmont Heights.
Homes situated along Belmont's steep western slopes rest on expansive adobe clay soils that aggressively shrink and swell with seasonal rains, creating intense shear forces that snap rigid clay sewer laterals. Meanwhile, gravity descent from high-elevation municipal water storage reservoirs along Ralston Avenue delivers municipal water pressure in excess of 110+ PSI. Daso Plumbing installs flexible seamless HDPE trenchless sewer laterals that flex with ground shifts, alongside calibrated Pressure Reducing Valves (PRVs) that protect delicate appliances from destructive pressure spikes.
