Specialized plumbing engineered for Palo Alto's all-electric reach codes and architectural innovation. We install City of Palo Alto Utilities (CPAU) rebate-compliant hybrid heat pump water heaters, detached ADU utility tie-ins, and luxury custom remodels.
Palo Alto leads California in environmental sustainability and municipal reach codes. Under the City of Palo Alto Utilities (CPAU) decarbonization roadmap, homeowners are encouraged to replace fossil-fuel gas water heaters with ultra-efficient hybrid heat pump water heaters , supported by generous municipal rebates.
Additionally, Palo Alto's boom in detached Accessory Dwelling Units (ADUs) requires complex underground sewer lateral extensions, sub-metered water loops, and clean copper distribution. Daso Plumbing coordinates every phase—from permit approvals and rebate paperwork to flawless master plumbing execution.
Balancing historic preservation with modern all-electric energy mandates.
Converting gas water heaters to heat pumps requires proper 240V circuit sizing, condensate drain routing, and sound dampening.
Adding an accessory dwelling unit demands precise calculation of main water meter capacity, fixture units, and sewer lateral fall.
Professorville and Old Palo Alto homes suffer from rust-choked galvanized lines and brittle clay sewer laterals infiltrated by heritage oaks.
Custom multi-valve showers require dedicated copper loop headers to prevent temperature drops when other household fixtures run.
Real systems installed by Daso crews on Peninsula properties.
Complete turnkey gas-to-electric heat pump conversions. We handle unit sizing, condensate drainage, sound isolation, and all municipal permit documentation.
Full underground trenching and tie-in connections for accessory dwelling units. We engineer sanitary sewer lines, secondary water submeters, and gas/electric distribution.
Replace failing clay or cast-iron sewer laterals without destroying Palo Alto's protected heritage trees, brick driveways, or mature landscaping.
