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>

Do I need a permit to install a plunge pool?

• <div><p>Generally speaking, most municipalities require you to get a permit when you build a pool. Whether or not you need a permit to install a plunge pool will depend on your local laws. It’s always better to check with your HOA and town clerk before digging for a new pool. Otherwise, violations could result in hefty fines. </p></div>

These germs can cause a range of illnesses from gastrointestinal issues, to rashes, and respiratory problems.</p><p>The best thing to do is to get rid of the algae first, test and balance the water, and then you can enjoy swimming without any worries.</p></div>

Q: Can you put too much salt in a pool?

• <div><p>Yes, it&rsquo;s possible to put too much salt in your saltwater pool, and doing so can cause a number of problems, including corroding metal parts and causing the chlorinator to stop working correctly.
