You may be wondering, “Do I need a permit to replace my water heater in Daly City?”

Currently, Daly City requires a permit for a water heater installation. The good news is we can pull the permit for you, and it will not slow down any work on our end.

Every few years, Daly City water heater codes change to adopt new installation and safety measures. While intended to increase your overall home safety, these code requirements can result in extra installation charges.

Some customers scoff at the idea of paying for a permit for a water heater replacement, but the fact of the matter is water heaters can be dangerous if not installed correctly. In fact, water heaters cause more property damage than any other home appliance. And if the unit is not installed to code by a licensed professional and causes damage, your home insurance could reject any claims. That’s why we put a premium on safety and doing everything by the book.

Your expert technician will go over an item-by-item checklist of all applicable safety codes needed for your installation prior to any work being completed, or cost to you.

We try to keep this information as up-to-date as possible, but your Daly City installer can answer any specific questions you have.

Local Water Heater & Plumbing Codes – Daly City, CA

Water Heater Codes Currently Enforced in Daly City

Approved Location – The CA Plumbing Code regulates the location of Gas water heaters. They cannot be located in closets unless it is for the exclusive use of the water heater. They also cannot be placed in bathrooms or bedrooms. This is to prevent accidents and ensure there is no human contact with the small amounts of CO (Carbon Monoxide) that is released into the air. Daly City enforces this regulation.

Earthquake Straps – A California Plumbing Code requirement states that water heater tanks must be fastened down with earthquake straps – one strap on the top third and one on the bottom third. This requirement is enforced for your safety by Daly City.

Venting – Gas combustion water heaters normally produce carbon monoxide (CO) requiring correct venting. The size of the water heater will determine what size the vent should be. If the vent material tends to get hot there must be an appropriate amount of clearance from flammable or combustible exteriors. This requirement is enforced by Daly City.

Pans and Drains – If a water heater is positioned in either an interior location or on a built-in platform, damage could occur from water leakage. The CA Plumbing Code requires a pan under the water heater with a drain line to the exterior. This is enforced by Daly City. While CPVC material is an approved material for use as drain lines, Daly City ill not allow it to be used.

Pressure and Temperature Relief Drain (“P&T Drain”) to the Exterior – The California Plumbing Code requires P&T relief drains to be run to the exterior. This requirement is in place to prevent accidental scalding while the pressure and temperature relief is discharging. Daly City currently enforces this. Although CPVC is an approved material for drain lines, Daly City will not allow its use. Daly City may allow a P&T relief valve to be piped to the garage if there is a drain on the garage floor.

Dedicated Water Shutoff – In cases where your water heater may need servicing dedicated water shutoff lets you turn off the water to the tank, leaving water available for the rest of the house. This code item is actively enforced in Daly City.

Pipe Insulation – Pipes located in unconditioned space are required to be insulated in Daly City.

Bonding – The CA Electric Code requires that gas and water pipes be grounded. They can be successfully grounded if the pipes are bonded with 6 awg wire and clamps. It is possible for your pipes to become energized if your wires are near the pipes and they start deteriorating. This is a dangerous situation and the requirement is enforced by Daly City.

Sediment Traps – A sediment trap, located on the gas line that runs to your water heater, catches moisture and debris in the gas line and prevents it from entering the combustion chamber of the water heater. Currently, Daly City actively enforces this.
