Water Heater codes & Permits

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

Currently, Hayward does require a permit for a water heater installation. The good news is we can obtain it for you, and it will not slow down any work on our end.

Every few years, Hayward 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

Water Heater Codes Currently Enforced in Hayward

  • Approved Location – Most types of water heaters cannot be located in bedrooms, bathrooms, or closets (unless the closet is used solely for the water heater). This prevents accidents and avoids human contact with the small amounts of CO (Carbon Monoxide) that spill from gas heater vents. Hayward currently enforces this.

    Earthquake Straps – California is an earthquake zone and 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. Inspectors in Hayward enforce this regulation.

    Venting – Most water heaters in Hayward are gas combustion which generate carbon monoxide (CO) as part of the combustion process. These water heaters must be vented properly and the vent must be adequately sized for the water heater. Combustible/ flammable surfaces must have proper clearance if the vent material gets hot. Hayward currently enforces this requirement.

    Pans and Drains – A water heater positioned in an interior location or on a built-in platform could cause damage from leakage. The CA Plumbing Code requires a pan under the water heater with a drain line to the exterior. Hayward enforces this requirement. However, CPVC, which is approved material for all kinds of drain lines, is not allowed to be used by the city of Hayward.

    Pressure and Temperature Relief Drain (“P&T Drain”) – The California Plumbing Code requires your P&T drain be run to the exterior to prevent accidental scalding while the pressure and temperature relief is discharging. Hayward currently enforces this. Hayward will sometimes allow the use of a Watts 210 valve if piping to the exterior is not possible. Hayward also may allow the P&T Drain to run into a water heater pan if they cannot be run separately. Although CPVC is approved material for all types of drain lines (and less expensive than copper), Hayward will not allow any CPVC use.

    Dedicated Water Shutoff – A dedicated water shutoff is required for water heaters. This allows water to the water heater to be shut off for servicing, while water to the rest of the house is still available. Hayward enforces this code item.

    Pipe Insulation – Pipes located in space that is unconditioned must be insulated in Hayward.

    Bonding – The California Electric Code requires that your water and gas pipes be grounded. You can ground all the pipes by bonding them with 6 awg wire and clamps. Because plumbing is usually built near electrical wiring your pipes could be energized if the wires become frayed. Inspectors in Hayward currently require this.

hayward Water Heater repair

Water heaters are constantly operating, heating and storing hot water for your use. They’re built to last, but if yours starts leaking or you’re out of hot water, you may need to have your water heater repaired.

Typically, a water heater comes with a warranty anywhere from 5-15 years on parts. For this reason, if you start experiencing issues, try to find the model & serial number of your water heater so we can determine if it is still under warranty. Our service technicians are local to Hayward and are familiar with most regional heater applications, brands and models.

It’s important to note, if your existing units is more than 10 years old, it’s probably nearing its last legs. Considering the cost of labor, rather than repairing it, a more prudent financial choice might be to just replace the water heater.

In Hayward, common water heater repairs and maintenance include:

    • Replace the thermocouple – Sometimes a fix is as simple as one small part. This is often the case when a water heater isn’t heating water; typically it just needs a replacement thermocouple, which allows the heater to take in gas.


    • Replace the anode rod – Over time, the minerals in your water and pressure in your tank will cause corrosion of your water heater. Anode rods prevent tank corrosion because they attract the corrosive elements, keeping them away from the storage tank. The installation of dual anode rods, or a replacement can extend the life of your heater.


    • Pilot light – This simple mechanism is also responsible for lots of water heater repairs. Sometimes the light can simply go out and just needs to be re-lit. Other times, the assembly has failed, and must be replaced.


  • Drain storage tank – Some newer water heaters have self-cleaning tanks, however, older ones need to be manually drained to prevent a sediment build-up. If you fail to drain the sediment, eventually the mineral deposits will collect and shorten the useful life of your water heater.
