How far off can a pool be unlevel?

• <div><p>An aboveground pool should be level within 1 inch—and it starts to become unsafe after a couple of inches. Any slope will lead to an uneven distribution of water, which will put pressure on your pool’s structure, wearing down the pool liner. In certain cases, it could cause your pool to collapse. Even if you’re within a safe window, you may still notice that the water level is uneven.</p></div>

How do I find a pool leak?

• <div><p>Pool leak detection dye is a great way to test specific areas of your pool for unbalanced water flow. By releasing the dye close to possible trouble areas—like around the seal of the skimmer—you can narrow down the potential crack. However, it's best to call a professional pool repair team near you if an initial patch does not keep your water level from lowering.</p></div>

Q: How does a saltwater pool convert chlorine?

• <div><p>The generator in your saltwater pool conversion kit transforms sodium chloride&mdash;the same salt as table salt&mdash;into chlorine. A process called electrolysis sends electricity through the water to interact with the chlorine ion. This ultimately creates the chlorine that keeps your pool safe and clean. The cell in your saltwater chlorine generator is the part that converts the salt into chlorine.</p></div>

Q: Do I need to shock my pool when I first fill it?

• <div><p>Yes, you will need to <a href="https://www.angi.com/articles/how-to-shock-pool.htm">shock your pool</a> with high levels of chlorine or bromine when you first fill it to kill off bacteria and pathogens. You&rsquo;ll need to wait for the chlorine concentration to come back down to a safe level before swimming. After that, you can test and maintain the chlorine and other levels as normal. The only exception to this is if you get pool water delivered by a professional. In that case, the water might come pretreated, so you might not need to shock it. </p></div>

Q: How long do concrete pools last?

• <div><p>A well-built and well-maintained concrete pool should last anywhere from 50 to 75 years. Concrete is prone to cracking, so winterization and regular pool repairs are particularly important. Water can seep into existing cracks, freeze, and make them worse. Most homeowners should resurface their concrete every few years to maintain their pool&rsquo;s lifespan. </p></div>
