Plumbing Codes For Water Heater Replacement

Plumbing Codes For Water Heater Replacement

Plumbing codes are a set of rules, guidelines, and regulations imposed by local authorities and states to govern the design, installation, and inspection of plumbing systems. The purpose of plumbing codes is to ensure plumbing systems work efficiently and safely. When you’re replacing your water heater, it’s necessary to follow plumbing codes to ensure the unit is installed properly and prevent safety hazards. Violating plumbing codes can lead to stiff penalties and accidents.

In this article, we will look at the plumbing codes for water heater replacement to help you perform water heater installation as safely as possible.

  • Expansion Tank

It’s necessary to install an expansion tank when replacing your water heater. An expansion tank is a small tank designed to handle the thermal expansion that occurs when water heats up in the water heater. This tank has a bladder that absorbs water to reduce excess pressure in your water heater. When the pressure in your water heater reduces, the water that’s absorbed into the bladder flows back into your water heater. Without an expansion tank, excess pressure that builds up can damage various components of your water heater.

  • Pans and Drains

Property owners are required to install a drain pan with a drain line underneath a water heater tank to prevent damaging leaks. A drain pan provides the first line of defense against leaks and accidental spillage by collecting water and channeling it to a drain line. Without a drain pan, you’re more likely to suffer water damage if there is a leak.

  • T&P Valve

Many municipalities require homeowners to install a T&P valve (pressure and temperature relief) on water heaters to provide temperature and pressure protection. A T&P valve opens and releases pressure inside the tank when your hot water temperature exceeds 210°F or 150 PSI. If you don’t install a T&P valve on a water heater, the tank may rupture or explode when the temperature or pressure gets too high.

  • Water Pressure Regulators

As the name suggests, a water pressure regulator is a valve that regulates pressure in the water heater tank. This valve is required when water pressure exceeds 80 PSI to prevent damage to your water heater.

  • Earthquake Straps

Earthquake straps are required in many areas to prevent damage to a water heater in case of an earthquake. Typically, these straps are positioned near the top and the other towards the bottom.

  • Location

There are some locations where you cannot install a gas or propane water heater due to the risk of CO poisoning. It’s advisable to consult with the local authorities when considering installing a gas or propane water heater.

These are some of the plumbing codes homeowners in most areas should follow when replacing water heaters. Keep in mind that plumbing codes can vary from one state to another.
