When it comes to the plumbing system in your home, the water heater is one of the most important components. It’s responsible for providing you with hot water for showers, baths, dishes, and laundry. If your water heater isn’t working properly, it can be a major inconvenience. That’s why it’s important to understand the basics of water heater plumbing so that you can troubleshoot problems and make repairs when necessary.
Types of Water Heaters
There are two main types of water heaters: tank and tankless.
- Tank water heaters store a reservoir of hot water in a tank. When you turn on a hot water faucet, the hot water from the tank is released into the pipes. Tank water heaters are the most common type of water heater in homes.
- Tankless water heaters heat water on demand. When you turn on a hot water faucet, cold water flows through a heat exchanger, where it is heated by a gas burner or electric heating element. Tankless water heaters are more efficient than tank water heaters, but they are also more expensive to purchase and install.
Water Heater Components
The main components of a water heater include:
- Tank: The tank is where the hot water is stored. It is usually made of steel or fiberglass.
- Heating element: The heating element is what heats the water in the tank. It is usually made of copper or nickel-chromium alloy.
- Thermostat: The thermostat controls the temperature of the water in the tank. It is usually set to a temperature between 120 and 140 degrees Fahrenheit.
- Pressure relief valve: The pressure relief valve prevents the water pressure in the tank from getting too high. It is usually located near the top of the tank.
- Drain valve: The drain valve is used to drain the water from the tank. It is usually located near the bottom of the tank.
Is Water Heater Plumbing: Troubleshooting Common Problems
If you’re having problems with your water heater, there are a few things you can check before calling a plumber.
- No hot water: If you’re not getting any hot water, the first thing to check is the thermostat. Make sure that it is set to the correct temperature. If the thermostat is set correctly, the next thing to check is the heating element. The heating element may be burned out and need to be replaced.
- Not enough hot water: If you’re not getting enough hot water, the first thing to check is the size of the tank. The tank may be too small for your needs. If the tank is the correct size, the next thing to check is the heating element. The heating element may be not heating the water properly.
- Water is too hot: If the water is too hot, the first thing to check is the thermostat. The thermostat may be set too high. If the thermostat is set correctly, the next thing to check is the heating element. The heating element may be heating the water too much.
- Leaking water: If your water heater is leaking water, the first thing to check is the drain valve. The drain valve may be loose or damaged. If the drain valve is not the problem, the next thing to check is the tank. The tank may be cracked or corroded.

- Replacing the thermostat: Replacing the thermostat is also a relatively easy repair. Simply turn off the power to the water heater, remove the old thermostat, and install the new thermostat.
- Replacing the pressure relief valve: Replacing the pressure relief valve is a bit more difficult than replacing the heating element or thermostat. However, it is still a repair that you can do yourself if you’re comfortable working with plumbing. Simply turn off the water supply to the water heater, drain the tank, and remove the old pressure relief valve. Install the new pressure relief valve and tighten the nuts.

- Flush the tank: Flushing the tank once a year will help to remove sediment and scale buildup. To flush the tank, simply turn off the power to the water heater, drain the tank, and then refill it.
- Check the anode rod: The anode rod is a metal rod that is inserted into the tank to help prevent corrosion. The anode rod should be replaced every few years.
- Insulate the tank: Insulating the tank will help to keep the water hot longer. You can purchase insulation wraps at most hardware stores.
