Cupertino Water Heater Installation


Fast Water Heater Company services all of Cupertino, California. If you’ve woken up to the surprise of a leaking hot water heater or a cold shower, we guarantee same-day service, if you call by noon. Our hours are 7 a.m. – 8 p.m. Monday-Friday and 8 a.m. – 5 p.m. Saturday & Sunday.

We’re homeowners too and know emergencies don’t conveniently occur just during the week; we’re open seven days a week and don’t charge extra for weekend service calls.

As the water heater experts, we can service, replace or install electric or gas water heaters, standard tank or tankless models and even install hybrid heat pump systems in certain situations. Whether you need a repair, installation, general maintenance, you’re looking for codes or water heater rebates, we’re here to help and we offer free estimates without the hassle of a “trip fee” like most plumbing companies.

All our certified technicians are background-checked and have years of water heater experience before they ever step foot into your Cupertino home.

Try to find the model number and serial number of your water heater before you call so we can identify the age, warranty and any other pertinent information about your existing unit. (This info can be found on a large sticker usually on the side of the water storage tank.)

Cupertino requires a permit for the installation of a hot water heater (this will not delay any work, just will schedule a safety inspection at a later date).

Water Heater codes & Permits

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

Currently, Cupertino 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, Cupertino 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 – Cupertino, CA

Water Heater Codes Currently Enforced in Cupertino

  • Approved Location – Regulations state that most water heaters cannot be located in areas such as closets, bathrooms or bedrooms (unless it’s used exclusively for the water heater). This prevents accidents as well as human contact with slight amounts of CO (Carbon Monoxide) that escapes from gas heater vents. Cupertino enforces this regulation.

    Earthquake Straps – Water heaters require certified earthquake straps on the bottom and top thirds of your water heater. Cupertino enforces this regulation for your safety.

    Venting – Since Carbon Monoxide(CO) is produced by Gas combustion water heaters they require proper venting. The size of the water heater determines the size of the vent. If the vent material gets hot there must be good clearance from flammable or combustible areas. This requirement is enforced by inspectors.

    Pans and Drains – If your water heater is positioned in an interior location or on a built in platform damage could occur from leakage. The CA Plumbing Code requires a pan under the water heater with a drain line to the exterior. Cupertino enforces this requirement. However, CPVC, which is an approved material for all kinds of drain lines (and less expensive than copper) is not allowed to be used.

    Pressure and Temperature Relief Drain (“P&T Drain”) to the Exterior – To prevent accidental scalding while the P&T drain is discharging, the CA Plumbing Code requires your P&T relief to be run to the exterior. Inspectors currently enforce this. In cases where piping to the exterior is not possible, Cupertino will not allow the use of a Watts 210 valve as a substitute to draining to the exterior.

    Dedicated Water Shutoff – If your water heater needs servicing a dedicated water shutoff allows you to turn the water to the water heater off without having to turn off the water to the rest of the house. This code item is actively enforced in Cupertino.

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

    Bonding – Your gas and water pipes are required to be grounded by the California Electric Code. Bonding the pipes with 6 awg wire and clamps effectively grounds all the pipes. This is a requirement because plumbing is regularly built near electrical wiring. If the wires degrade, they could energize your pipes. Inspectors in Cupertino are currently requiring this.

    Sediment Traps – Sediment traps are found on gas lines running to your water heater. The trap catches moisture and debris that gets into the line preventing it from entering the combustion chamber of the water heater. Currently, local inspectors enforce this.

Cupertino Water Heater repair

Even in Cupertino, 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 Cupertino and are familiar with most regional heater applications, brands and models.

It’s important to note, if your current model 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 Cupertino, 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 needs to 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.
