Water Heater Repair & Installation

No hot water is not a wait-and-see problem. All Systems Pros repairs and replaces tank water heaters across Pasadena, Monrovia, and the San Gabriel Valley — with skilled technicians, honest recommendations, and a price you approve before any work begins.

If a repair is the right answer, that's what we'll tell you. If the unit is at the end of its life, we'll walk you through replacement options and handle every code requirement that comes with a proper California installation.

A code-correct installation, not just a swap

A water heater replacement in California is more than lifting a new tank into place. Our installations address every safety and code item the job requires, including:

• Thermal-expansion control for closed systems, with the method selected for the heater and local requirements
• Drain pan and drainage where required by the installation and local rules
• T&P relief valve and discharge pipe
• Approved gas shutoff and connection where applicable to the selected heater
• Gas sediment trap where required by the appliance instructions and code
• Venting suitable for the selected fuel-burning heater, where applicable
• Earthquake straps (required in seismic areas)
• Water shut-off valve for proper service access
• Required connection tests, leak checks, and inspections for the work performed

True Transparency Pricing, honest recommendations

A typical full water heater installation runs $4,250–$5,200 depending on the unit and the upgrades your home's existing conditions and local code require. You'll get a clear written estimate — and a straight answer on whether repair or replacement is the better long-term investment.
