But fortunately, pool lights and swimming pools are designed to make it easy and safe to replace the lights without needing to drain the water. Instead, you can turn off the electricity to the pool as a safety precaution, unscrew the pool fixture, pull it up and out to the side of the pool, then change the bulb.</p></div>

Question 1

Can I use chlorine tablets in a salt water pool?

Accepted Answer

•

Yes, you can use chlorine tablets in a salt water pool. It is not the standard recommended practice, but if your pool needs more chlorine, adding tablets can help temporarily fix the problem. Only add as many tablets as needed to keep your chlorine level around three parts per million. After adding the tablets, test your water to determine the chlorine content.

Question 2

Do you have to drain your pool to convert to salt water?

Accepted Answer

•

Generally, you do not need to drain your pool to convert it to a saltwater system. The main exception is if you have used an antibacterial agent containing polyhexamethylene biguanide to sanitize your pool, as these sanitation products do not mix well with saltwater systems. If this is the case, you will need to start fresh. You can either drain the pool or treat the existing water with a high dose of chlorine to remove the antibacterial agent. If you choose the chlorine treatment, wait several days to allow the chlorine to work before proceeding with the conversion. If you are unsure whether this applies to your pool, consult a pool technician.

Question 4

Does a pool pump use a lot of electricity?

Accepted Answer

•

Yes, pool pumps use a significant amount of electricity, making them one of the biggest energy consumers in a home. A pool pump can use up to three times as much electricity as a refrigerator. Typically, a residential pool pump consumes about 1 kilowatt-hour (kWh) for every hour it runs. Because pumps often need to run for about eight hours a day to properly filter the water, this can add up to an annual consumption of 3,000 to 5,000 kWh, which can cost between $480 and $800 per year based on average electricity rates.

The amount of electricity your pump uses depends on its size, energy efficiency, and daily run time. To lower your energy consumption, you can choose an energy-efficient or variable-speed pump, ensure it is correctly sized for your pool, and run it only for the minimum time required to keep the water clean.

Question 5

How long do concrete pools last?

Accepted Answer

•

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’s lifespan.
