If your water heater is nearing a decade old or you've had to repair it many times, the time may have come for a replacement. Replacing a traditional hot water tank is easy and can save you money in the long run.
A few essential parts need to work together for the tank to heat water properly. These include an anode rod, dip tube, and pressure relief valve.
Anode Rod
The anode rod is one of the essential parts of your hot water tank. It protects your tank from corrosion by "sacrificing" itself so that the other metal components of your water heater system can stay intact longer.
The rod is made of magnesium, aluminum, or aluminum/zinc alloys. The anode rod will corrode over time, but it will also release electrons into the water, which can help keep other metals in your water system intact longer.
How long an anode rod will last inside your hot water tank depends on many factors, including the chemistry of the water. For example, the more corrosive your water is, the faster it will erode the anode rod.
Fortunately, replacing an anode rod is relatively easy, though it requires specific plumbing skills and tools. If you need help determining whether you can do it yourself or if your current anode rod needs to be replaced, contact a local licensed plumber to come and quote you the work.
Dip Tube
The dip tube is one of the essential components of your hot water tank. It helps move cold water to the bottom of your tank so that it doesn't mix with the hot water that rises.
It can also help reduce sediment buildup in the tank and protect against corrosion. You should inspect your dip tube for cracks and small holes at least once a year.
If you notice any signs of a damaged dip tube, it's time to replace it. This is a relatively simple task, and it can be done by yourself or with the help of a plumber.
First, turn off the cold water inlet valve. Then, drain the hot water outlet to remove any pieces of plastic that might be stuck in your pipes or faucets. Once you're done, reconnect the cold water inlet and main line. This will remove any air from the system and make working on the dip tube easier.
Pressure Relief Valve
The temperature and pressure relief valve is one of the most important parts of your hot water tank. If it fails to work properly, it could cause serious problems with the system and your health.
The valve consists of a lever that flips up and down. When you flip it up, water flows into the pipe and out to a discharge spot below the water heater.
It's important to test this valve every couple of years, or at least once a year, to see if it works correctly. Doing this will help you to detect any problems before they become dangerous.
The valve can have a variety of characteristics, including reseating pressure (C), set pressure (D), maximum relieving pressure (E), blowdown (F and G), and simmering value (H). Other factors include body and seal materials.
Drain Valve
When you replace your hot water tank, a drain valve is one of the essential parts you'll need to install. These valves are designed to flush sediment from the tank and help boost performance.
Using a drain valve is also essential for cleaning out your tank, preventing the buildup of minerals in the water, and reducing energy costs. Homeowners should perform this maintenance task at least twice a year or more frequently in areas with hard water.
If the drain valve on your water heater is clogged, you'll need to replace it. A new drain valve can be installed quickly and should last longer than the old one.
Before replacing the drain valve on your water heater, ensure you have all the necessary tools. This includes a screwdriver, pipe wrench, and some plumber's tape to secure the valve's threads. You'll also need a bucket to catch any sediment that may spill out.
