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

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

Federal Way 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 Federal Way?”

Currently, Federal Way rquires 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, Federal Way 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 Codes – Federal Way, WA

Water Heater Codes Currently Enforced in Federal Way

  • Approved Location: Most of the time, it is prohibited to have a water heater installed in a bathroom, wardrobe or bedroom. This protects against accidents and prevents individuals from the trace amounts of carbon monoxide that can occasionally leak from the vents in water heaters. Inspectors in Federal Way pay attention to enforcing this rule.

    Earthquake Straps: All water heaters in Washington are expected to be secured with earthquake straps. This is because Washington State is situated in a known earthquake zone. Most of the time, Federal Way’s inspectors will see to it that this regulation is followed.

    Venting: It is very important that water heaters are vented correctly. Most water heaters run on gas combustion and thus the generation of carbon monoxide is an outcome of their operation. This rule is avidly enforced in Federal Way.

    Pans and Drains: The plumbing code states that any water heaters found on a platform or in a place indoors where leaking might lead to damage should have a pan under them, with a line to enable draining attached.

    Pressure Regulating Valves: High water pressure in plumbing systems must always be regulated, to avoid potential damage. When we come to your residence, we will be sure to evaluate your PSI and, if it exceeds 80, then we will be likely to recommend that you consider a regulating device.

    Greasepack Gas Valve Replacement: Gas valves of the greasepack variety are known to malfunction, so, when we visit your home, we will check what type of valve you have installed. Those that are greasepack in style will have to be replaced.

    Bonding: When electrical wiring and plumbing pipes are near each other, problems, such as energizing, can occur easily. So we will take the time to cover your pipes with clamps and appropriate wire, to make sure that they are grounded.

    Sediment Traps: Federal Way inspectors take the time to check whether or not you have a trap for sediment, to stop it from running into your water heater’s combustion chamber.

    Dedicated Water Shutoff: If your water heater has a shut off independent of that of your home’s general water supply, then you can easily close down your water heater while still enjoying the convenience of running water. Federal Way sees this regulation as sufficiently important to insist that it is obeyed.

    Pipe Insulation: Insulation must protect any pipes that are in a space that lacks conditioning.

Federal Way Water Heater repair

Water heaters are one of the hardest-working appliances in your home, heating and storing hot water for your use. They’re built to last, but if yours starts leaking or stops producing hot water, your water heater may need repairs or service.

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

It’s important to note, if your existing model is more than 10 years old, it’s probably nearing its last legs. Considering the cost of labor, it might be cheaper in the long run to just replace the water heater.

In Federal Way, our technicians frequently experience the following water heater repairs and maintenance issues:

    • 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, so it 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.
