3 Common Water Heater Repairs

Monday, April 13th, 2015

When your water heater breaks down, you want service fast. You don’t have days to sit around and wait for repairs, which is why many homeowners attempt to fix the water heater on their own. Sure, there are various guides and manuals out there to help homeowners feel more confident about diagnosing a water heating issue. But if you attempt these repairs without the help of a trained professional, you risk one very serious possibility: being without hot water for even longer. Here are three common water heater repairs which go more smoothly if done by a professional with the proper tools and expertise.

  • Flushing the Tank – “Hard water” is an issue that affects the majority of plumbing systems in the United States, but it shouldn’t pose any threat to the members of your household. However, the minerals left behind by hard water may begin to fill up a tank, reducing the volume inside and increasing pressure levels. When you hear a loud banging noise, call a professional right away. It could indicate a tank that simply needs to be flushed of mineral deposits.
  • Replacing the Anode Rod – The anode rod of your water heater is a simple part that serves no real mechanical value. However, this small rod is vital in maintaining the life of your water heater. This part is made of magnesium or aluminum, elements which are more corrosive than the steel tank. This means the rod will corrode before the steel tank does, but it must be replaced from time to time for optimal value.
  • Replacing the Dip Tube – The dip tube is the portion of your unit that allows cold water to flow into the tank, leading all the way down to the bottom where the burner (or electric heating element) is located. If this cracks, cold water can mix with the hot water, so replacement is generally necessary at this point.

Potential Problems with the Water Heater’s Dip Tube

Friday, January 9th, 2015

Have you noticed that the water coming from your hot water tap is tepid at best, and runs out quickly? There are a few reasons this can happen, and one of them is problems with the dip tube inside the storage tank of your water heater. You may not even be aware of a dip tube or what it does, so we’ll explain more about it below.

What Is a Dip Tube?

All water that enters your water heater storage tank is cold; it is heated at the bottom of the tank by combustion or electricity. To ensure that the new, cold water doesn’t mix with the stored warm water, a slender, long tube is attached directly to the cold water inlet. This tube is the dip tube, and it forces all new, cold water to the bottom of the tank so it can be heated and rise to the top of the tank for use in your home.

Potential Problems

There are several common problems that can develop with dip tubes that can affect the temperature of your water:

  • Cracks – when there are cracks in the dip tube, the cold water will escape and mix with the hot water stored in the tank.
  • Breakage – sometimes dip tubes break off, leaving a broken piece free inside the storage tank. This results in the incoming cold water mixing with the hot water, so your water will be tepid at best.
  • Disintegration – a defective dip tube may disintegrate inside the tank. This will affect your water temperature and you may also see pieces of white or gray plastic coming through faucets or trapped in faucet aerators.

Defective Dip Tubes, 1993-1997

The vast majority of dip tubes manufactured between 1993-1997 were made of a defective plastic that became brittle from the constant exposure to the hot water in the storage tank. So, if you have a water heater that was manufactured during this time period, you may have a defective dip tube to contend with. You can check the date of manufacture yourself by looking at the first 4 numbers of your water heater’s serial number; the first two numbers represent the month of manufacture and the last two numbers represent the year. If any of the last two numbers in this sequence are 93, 94, 95, 96 or 97, you may want to have a professional check your water heater’s dip tube.

If your water is tepid, or you are seeing pieces of what plastic coming from your faucets, call Air Conditioning Experts, Inc., and make an appointment for water heater repair in Atlanta.

Atlanta Water Heaters Repair Guide: The Sacrificial Anode Rod

Friday, December 19th, 2014

Have you ever turned on a faucet in your home, and been confronted with brown or otherwise discolored water? Do you have a tank-equipped water heater? If so, chances are you have a problem with the sacrificial anode rod. But what is the sacrificial anode rod? Read on to find out, and to find out why it’s so important to keeping your water clean.

What is the Sacrificial Anode Rod?

If any water tank will eventually begin to corrode and rust from the inside out as it is constantly exposed to water. Most water heaters have linings along the inside of the tank to help prevent this, but even they will eventually crack from the heat. To address this issue, virtually every water heater that uses a tank includes a part called a sacrificial anode rod.

This is a long, metal rod that is inserted into the top of the water tank. While the rod is in good condition, the water will begin to rust it instead of the lining of the tank. This is what earned it the name “sacrificial rod.”

Why the Sacrificial Rod Needs Replacing

Over a long enough period of time, the anode rod will become so corroded that it can no longer attract rust to itself. When this happens, the lining of the tank will begin to rust. This is likely the cause of your water being discolored when you turn on the faucet.

Aside from simply being gross, rust in your water means that your water tank is losing integrity. If the rust has progressed far enough, it will eventually cause the entire tank to rupture, potentially causing thousands of dollars in water damage on top of necessitating a new water tank.

So, how can you prevent this from happening? Replace the anode rod every five years or so. That should be often enough to always have a functioning anode rod in the heater.

If you don’t know how to replace the sacrificial anode rod, call Air Conditioning Experts, Inc. Atlanta. We provide water heater repairs throughout Atlanta.
