Here's How You Know When To Replace a Water Heater

Gas Water Heater Venting

For many years, the standard means of venting combustion exhaust gases for a gas-burning water heater was with atmospheric venting. In this system, a metal draft hood at the top of the water heater channeled both exhaust gases and a small amount of fresh air from the room up a metal flue through the roof or to a common chimney. In many cases, installing a new water heater will be a matter of connecting the existing flue and draft hood to the new heater, though there are factors (such as pitch and draft of the connections) that make the process much more complicated than it seems. When done incorrectly, exhaust gases (including carbon monoxide) can remain inside the home, which is why this project is best left to professionals.

But the building code in some communities may require changing to a different means of venting whenever a new water heater is installed. Many areas now require a system known as direct venting, in which a special double-chambered vent pipe carries the exhaust gases out the side of the house at the same time fresh air is allowed in. This is often required in modern air-tight homes, to prevent the gas and airflow through the water heater flue from creating an air pressure difference, which can draw gases from the water heater burner into the home. Depending on how far the direct vent needs to run, code might also require a power fan that assists the flow of exhaust gas in the vent. In older, less air-tight homes, this is rarely a problem.

If your code requires that you change from a simple atmospheric vent to a direct vent or powered direct vent, this is a more complicated job. Most people should call a pro for this work.


All plumbing installations must conform to the local plumbing code, so consult the local building department for requirements in your area. Because installation varies by location and by the type of heater, the following steps merely show the general process and may or may not apply to your situation. As stated above, this project is best left to professionals.

That dull old paring knife

There are two schools of thought regarding paring knives. One is that you should get a really expensive one and sharpen it when necessary, and the other is that you should get cheap ones and replace them when they get dull. If you’ve got the cheap ones, chances are they’re dull. They can be replaced easily.

Every time you engage your vehicle’s brakes, a small amount of friction material is worn off the pads and/or shoes. Over time, the friction material will become thinner. If the pads or shoes are not replaced, the friction material will be worn off entirely, exposing the steel pieces that held the material. When these steel pieces come into contact with the discs or drums, excessively long braking distances and damage to the discs and drums will result. Look for these signs to know when to replace brake pads or shoes:


If a vehicle’s brake pads have wear indicators, a driver may notice a squealing, screeching or whining noise when the brakes are engaged. This sound is caused by a small metal attachment on the brake pad backing plate for just this purpose. Wear indicators work on the same principle as dragging fingernails across a chalkboard. When you hear it regularly while braking, it’s time to bring your car in to a brake specialist for an inspection. Note that not all brake pads come with this feature, so don’t rely on sound alone to assess your brakes’ condition.

When brakes are exposed to wet, damp conditions, such as after a rain storm, pads may exhibit a very similar screeching sound while braking. If a sound disappears after the first few times you use your brakes, that’s a good indicator that it was just a bit of moisture on the brake pads or shoes and not a sign they need to be replaced.


On disc brakes, you can also visually inspect your brake pads to know if it’s time to have them replaced, though it may require you to remove the wheels to do this. Looking down on the brake assembly or “caliper” holding the brake pads, you should see your brake pads compressed against your brake rotor. If the friction material on the pad or shoe is less than ¼ inch thick (about seven millimeters), consider having your brakes inspected, especially if it’s been a long time since your last inspection.


If you hear a deep, low noise that sounds like metal grinding or a rumbling growl, that can be a sign that not only are your brake pads worn away, but also your brake pads or shoes’ backing plates are making contact with the discs or drums. Since this metal on metal contact can very quickly cause even further damage in your braking system, bring your vehicle in to a service shop as soon as possible if you hear this type of noise.


Some vehicles have an indicator light on the dashboard that will signal when it’s time to replace the brake pads. Check your owner’s manual to see if your vehicle comes equipped with the low-pad warning system. Remember that if the light does come on, you’ll need to have your mechanic replace the warning sensors as well as the brake pads.

How Do I Replace a Hard Drive?

Maritsa Patrinos @Lifewire

To replace a hard drive, you'll need to back up any data you want to keep, uninstall the old hard drive, install the new hard drive, and then restore the backed up data.

Here's a bit more on the three required steps:

  1. Backing up the data you want to keep is the most important step in this process! The hard drive isn't the valuable thing—it's the priceless files you've created and collected over the years.

    Creating a backup could mean something as simple as copying files you want over to a large flash drive or other storage you’re not using. Better yet, if you’re not backing up regularly already, use this as an opportunity to start with a cloud backup service, so you never even run the chance of losing a file again.

    5 Ways to Back up Your Data and Keep It Safe

  2. Uninstalling the existing hard drive is easy. Make sure your computer is turned off and then disconnect the hard drive and physically remove it.

    The details here depend on the type of computer you have, but in general, this means removing data and power cables or sliding the hard drive out from the bay that it's installed into.

  3. Installing the new hard drive is as simple as reversing the steps you took to uninstall the one you're replacing! Secure the drive where the old one was before, and then reconnect the same power and data cables.

  4. Once your computer is back on, it’s time to format the hard drive, so it’s ready to store files. Once that’s done, copy the data you backed up to the new drive, and you’re set!

Use wildcard characters to find and replace text

Select View > Navigation Pane. In the Navigation Pane, select the magnifying glass. Select Settings , and then select Advanced Find & Replace. Select the Use wildcards check box. If you don’t see the Use wildcards check box, select . Select the Special menu, select a wildcard character, and then type any additional text in the Find what box. Select Find Next. Tips:  To cancel a search in progress, press + PERIOD. You can also enter a wildcard character directly in the Find what box instead of selecting an item from the Special pop-up menu. To search for a character that’s defined as a wildcard character, type a backslash (\) before the character. For example, type \? to find a question mark. You can use parentheses to group the wildcard characters and text and to indicate the order of evaluation. For example, search for <(pre)*(ed)> to find “presorted” and “prevented.” You can search for an expression and use the \n wildcard character to replace the search string with the rearranged expression. For example, type (Newman) (Belinda) in the Find what box and \2 \1 in the Replace with box. Word will find “Newman Belinda” and replace it with “Belinda Newman.” To replace found text: Select the Replace tab, and then select the Replace with box. Select Special, select a wildcard character, and then type any additional text in the Replace with box. Select Replace All, Replace, or Find Next. Tip: When you replace text, it’s a good idea to select Replace instead of Replace All. That way you can confirm each replacement to make sure that it’s correct.

Install the Sash

Hold the top sash with the exterior facing up and

Hold the top sash with the exterior facing up and the metal cams away from you. Tilt the sash a little and align the metal pivots with the slots in the jamb liner closest to the exterior. Make sure the pivots are above the sash lifts. Tilt up the sash and press outward on the jamb liner while you snap the top of the sash into place between the jamb liners. Slide the sash down until the metal cams contact the sash lifts. Repeat the process on the lower sash. If you have trouble pushing in the sash after you tilt it up, try working with one side at a time.
