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

Currently, Danville does require 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, Danville 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 local installer will be able to answer any specific question you may have.

Local Water Heater & Plumbing Permits – Danville, CA

Water Heater Codes Currently Enforced in Danville

Approved Location – Gas water heater vents release miniscule amounts of CO (Carbon Monoxide) into the air. To prevent accidents and avoid human contact with the CO, regulations are in place stating that water heaters cannot be located in closets (unless used exclusively for water heater), bathrooms or bedrooms. Danville enforces this regulation.

Earthquake Straps – As California is in an earthquake zone some regulations are required for everyone’s safety. Water heaters must have certified earthquake straps – one on the top third of the tank and one on the bottom third of the tank. Most inspectors in Danville enforce this regulation.

Venting – As most water heaters in Danville are gas combustion they generate carbon monoxide as part of the combustion process and must be properly vented. The vent must be adequately sized for the size of the water heater. Correct clearance from flammable or combustible surfaces must be allowed if the vent material tends to get hot. Danville inspectors currently enforces this requirement.

Pans and Drains – Water heaters located in an interior location or on a built-in platform could leak and cause water damage. Danville usually requires that a pan be placed under the water heater with a drain line running to the exterior. This is a requirement of the CA plumbing code. It is our experience that inspectors require the drain to run to the exterior.

Pressure and Temperature Relief Drain (“P&T Drain”) to the Exterior – To prevent accidental scalding while the P&T drain is discharging, the CA Code requires your P&T relief drain to be run to the outside.

Dedicated Water Shutoff – Water heaters with a dedicated shutoff are required by CA Plumbing Code. The shutoff allows water to the water heater to be turned off for servicing, while the water to the rest of the house is still available. Danville actively enforces this code item.

Pipe Insulation – Pipes exposed to unconditioned space are required to be insulated in Danville

Bonding – Water and gas pipes must be grounded. By bonding your pipes with 6 awg wire and clamps you can effectively ground all the pipes. Since plumbing is often built near your electrical wiring, it is possible your pipes could be energized if the wires were to deteriorate. Inspectors currently enforce this requirement.

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.
