Q: How do hot water heater expansion tanks work?

• <div><p>When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.</p><p>In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.</p></div>

Q: Are tankless water heaters better than traditional water heaters?

• <div><p>There are <a href="https://www.angi.com/articles/what-are-pros-and-cons-tankless-water-heaters.htm">pros and cons to tankless water heaters</a>. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate. </p></div>

Q: Are new water heaters better than old ones?

• <div><p>Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. </p><p>If you&rsquo;re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.</p></div>

Q: What’s wrong with high water pressure?

• <div><p>Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it&rsquo;s actually a silent threat to plumbing. </p></div>
