How to light your water heater’s pilot flame.

 

Step 1: Remove the bottom plate concealing the burner door and sight glass.
Remove the bottom plate

Step 2: Mark the temperature control, so you can return it to the original setting.
Mark temperature control

Step 3: Set the temperature and regulator dial to pilot lighting.
Set temperature and regulator dial

Step 4: Make sure your spark igniter is functional. Click it a few times, and check for spark through the slight glass.
Test the spark igniter

Step 5: Hold down the pilot switch and spark the igniter until the pilot flame is lit. Continue to hold the pilot switch down for 30 seconds to 1 minute. Once the pilot switch is released, the pilot flame should stay lit. If it goes out, the thermocouple, temperature cut-off switch, or gas control may be at fault.

Comments are off Sep 14, 2016

Collecting a bit of information from your current water heater can help determine possible issues and help provide an accurate estimate for repairs or replacement.

Model Number, Serial Number, and Capacity:

This information is located on a sticker on the front of the tank. With this helpful information we can determine replacement costs, and source parts if needed.

Here’s some examples of the sticker to look for. Taking a picture is always best.

Taking a picture showing the complete water heater and the venting can also be helpful, but usually not necessary.

How to replace a temperature and pressure (T&P) relief valve on a water heater.

 

Step 1: Determine you have the correct replacement for your relief valve. Match the size, temperature, and BTU rating of the old relief valve. This information is located on the end of the relief valve.
Determine the rating plates match

Step 2: Turn the gas control to the pilot setting. This is so the water heater won’t fire while it’s being worked on.
Turn gas control to pilot

Step 3: Close the cold water supply off to the water heater.
Close the cold water supply to the tank

Step 4: Drain off roughly 5-10 gallons of water from the tank. This will bring the water level in the tank below the level of the relief valve.
Drain some of the water heater

Step 5: Remove the drip tube from the relief valve.
Remove the drip tube

Step 6: Apply teflon tape to the threads of the new relief valve. In a clockwise direction, when the threads are face up and towards yourself.
Apply teflon tape to threads

Step 7: Remove the old relief valve with a wrench in a counterclockwise direction.
Remove the old relief valve

Step 8: Install the new relief valve hand tight first, and then the remainder with a wrench. Ensure the relief valve port is aiming directly down.
Install the new relief valve

Step 9: Teflon tape, and reinstall the drip tube.
Reinstall the drip tube

Step 10: Open the cold water supply only partially to allow the tank to fill slowly. This will help reduce water hammer.
Open the water supply partially

Step 11: Open a hot faucet preferably at the highest point in the residence. Leave the faucet open as the tank is filling to purge all the air from the system. Once the faucet runs steady water without any air, the faucet can be closed.
Open a hot faucet

Step 12: Open the cold water supply fully, and check for leaks.

Comments are off Mar 30, 2015

Click your brand of water heater for the warranty validation page

The serial number of your water heater will be needed to validate the warranty and confirm the age of the heater. The serial number is located on the rating plate/sticker on the water heater. Please note that most GSW and John Wood water heater serial numbers will work on the AO Smith warranty validation page.

Dip Tube Replacement

By

image
Comments are off Jan 28, 2015

Water heater not delivering as much hot water as it used to? Your heater’s dip tube may need to be replaced.

What is a dip tube?

The dip tube is a tube that is installed on the cold water supply of a water heater. It brings the incoming cold water to the bottom of the water heater to be heated, while the hot water is drawn of the top of the tank.

Signs you might need a replacement dip tube.

The most common sign that you might need a dip tube replacement is that the shower/tub hot water supply is not lasting as long as it used to. Another sign of a faulty dip tube is having small pieces of plastic clog up aerators on your faucets. This is a sign that the dip tube is deteriorating and pieces are starting to break off.

Here’s a example of a broken or damaged dip tube. When the dip tube is broken off near the top, as in this picture, the cold water supply is able to short circuit over to the hot side before being heated at the bottom of the water heater.

Piping Multiple Water Heaters: Series vs Parallel

By

image
Comments are off Feb 23, 2015

What is the best way to pipe multiple water heaters?
We get this question quite often.

Most of the water heaters that we see out there are piped in series. We strongly recommend running water heaters in parallel, but both have their benefits and downfalls.

Piping in series is when the cold water supply enters the cold side of heater #1 and then exits out of the hot side of heater #1. Then it enters into the cold side of heater #2 then exits out of the hot side of heater #2 to feed the demand. The main concern in this setup is that heater #1 usually has a higher demand on it. We see this constantly, as the first tank usually is always first to fail. If piped in series, it is best to have the first heater set to a lower temperature then the second. This reduces the stress on the first heater. The main benefit to this setup is ease of installation and cost.

Piping in parallel is when the cold water is piped in to the cold inlets of both heaters symmetrically. The water is then piped out of the hot side of each heater symmetrically as well. The reasoning behind piping the tanks symmetrically is to ensure both tanks are being filled and drawn from evenly. Both heaters should have isolation valves as well. There any many benefits to this setup, including the ability to run one heater at a time easily by isolating the other. This ensures in the event of a heater failure you will still have a hot water supply from the alternate heater. Another great benefit is maximizing output of the heaters. Piping in parallel gives you the full output of both heaters, as they are working as a team.

Example: Two 50 US gallon water heaters at 40,000 BTUs each, will now give you 100 US gallons at 80,000 BTUs.  That’s a lot of hot water!

Anode Rod Replacement

By

image
Comments are off Mar 19, 2015

A well-maintained anode rod in a water heater can help prolong the life of the heater and save you $$$.

When corrosion or absorption occurs in the water heater, the anode rod helps protect the metal tank. The corrosive properties of the water will attack the anode rod before attacking the steel tank of the water heater. This is why we hear the term “sacrificial anode”. Anode rod life depends on water quality and consumption. Most anode rods are made from magnesium or aluminum. Here’s a quick video on replacing an anode rod.

Welcome to My Hot Water, and our first blog post!

Born in small town Antigonish, Nova Scotia, Canada, I had a passion for anything mechanical. After receiving my Red Seal plumbing ticket, I founded The Hot Water Tank Company Ltd., a service plumbing company. After helping people with their hot water issues for years, I decided I wanted to be able to reach a broader audience. To that end, I created My Hot Water, an informational page intended to assist homeowners to make educated decisions about their hot water issues. My Hot Water provides expert advice and information to homeowners looking to choose trusted, local contractors, or looking to save money by tackling the job themselves.
