What happens if a water heater is not vented properly?

• <div><p>If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. </p><p>Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.</p></div>

Q: Do water heater installation laws change in different states?

• <div><p>Every city and state will have its own set of installation codes and laws. Some won&rsquo;t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a <a href="https://www.angi.com/nearme/water-heater-installation/">local water heater installation company</a> and local building codes to confirm which permits are required and what the specific laws are.</p></div>

Q: Are water heater thermocouples universal?

• <div><p>A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.</p></div>

Q: What other projects should I do at the same time as installing a new furnace?

• <div><p>When investing in a new furnace, it&rsquo;s smart to do a home energy audit. That will give you a list of any projects that would help with efficiency, such as sealing or replacing windows and insulating the attic. You can also take this time to install a smart thermostat if you don&rsquo;t already have one to make heating your home a breeze.</p></div>

Q: How big should a hot water heater expansion tank be?

• <div><p>The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.</p></div>

These men were very helpful in prep us for the job. They did a temporary hook up so that we would have water at night when we were at home and worked on the wiring and plumbing during the day when we were gone. We experienced little to no inconvenience. We highly recommend them.

Gary Henry and his helper came on a moment's notice to switch out our water well pump. That went well and even looked at one of my frost-free spigots that had lost water pressure. Fixed it for nothing and showed me how to fix it if needed in the future.
