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

Currently, Sammamish 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, Sammamish 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 Code – Sammamish, WA

Water Heater Codes Currently Enforced in Sammamish

Approved Location: It’s illegal and very dangerous to put a gas water heater in a bedroom or bathroom, or even a closet inside these rooms. Carbon monoxide is a byproduct of heating your hot water with natural gas. As this is a deadly, noxious gas, we must be sure that the install of your new water heater is in an approved location. The only exception to this code is to install a direct vent style (or power-direct vent) water heater. Sammamish inspectors are very strict in enforcing this rule.

Earthquake Straps: Earthquakes are all too common in the state of Washington, due to its geographical location, so Sammamish inspectors will check that your water heater is held in place with earthquake straps, secured on the bottom and top thirds of the water heater.

Bonding: Electrocution can be the result of electrical wiring and plumbing pipes being adjacent to one another. We stop this threat by grounding your pipes with wire and clamps.

Venting: Safe and adequate venting is an absolute must, both for safety and according to the City of Sammamish. The gas combustion mechanism that runs a water heater produces carbon monoxide, which can cause illness and can even be fatal. Proper venting prevents this from becoming a hazard.

Pans & Drains: Pans, linked to effective drain lines, should be situated below a water heater when it is on a platform or when it is inside, in a position where leaks can occur. This can help avoid water damage to the home.

Pressure Regulating Valves: If the water pressure of the home is higher than 80 pounds per square inch, damage can be inflicted on the plumbing system. Valves that work to regulate pressure play an essential role in stopping this from happening. If, upon measuring the PSI at your home, we discover it to be above 80 PSI, we will be sure to advise you to add a pressure regulating valve to your system.

Greasepack Gas Valve Replacement: Replacing any existing greasepack gas valve for a new one is necessary, as failure to do so might lead to malfunction.

Sediment Traps: Sediment can go into the combustion chamber, so it is essential to have a trap to stop it. Sammamish generally enforces this aspect of the code.

Dedicated Water Shutoff: Having a local shutoff valve enables you to cut off water supply to your heater, specifically, without compromising the water supply that services the rest of the house. Sammamish inspectors will most likely enforce this rule.

Pipe Insulation: Insulation is a must for pipes located in unconditioned areas.
