Does water run through a pool heater when not in use?

• <div><p>Water only runs through a pool heater when not in use if the heater doesn’t have a bypass system. A bypass system stops the flow of water through the heater when not in use. If you don’t have one, then yes, water will still run through the pool heater even when not in use. Not having a bypass system may increase the effects of wear and tear on your pool heater or disrupt the water’s chemical balance.</p></div>

How long can water sit in a pool without chlorine?

• <div><p>You should add chlorine within 48 hours of <a href="https://www.angi.com/articles/cost-fill-pool-water.htm">filling your pool with water</a>. In just 24 hours, bacteria and algae will begin to grow and contaminate your water. After that point, you’ll need to shock the water with high levels of chlorine, and you’ll likely need to do additional vacuuming to get the pool clean. It’s important to check your chlorine levels two to three times a week and add more chlorine as needed to maintain a healthy level.</p></div>

Install Above Ground Pools FAQs, answered by experts

The amount of time your fiberglass pool project will take depends on the size of the pool and whether you are installing add-ons like decking and landscaping. Overall, you should expect it to take four to six weeks to install. If you are dreaming of summer pool parties, make sure to budget enough time into the installation schedule to have your pool up and running in time for the swimming season.

If you don’t have one, then yes, water will still run through the pool heater even when not in use. Not having a bypass system may increase the effects of wear and tear on your pool heater or disrupt the water’s chemical balance.
