Filling Your Hot Tub: A Comprehensive Guide to Getting it Right

Your hot tub should be drained, cleaned and refilled with fresh water three to four times per year. While filling your hot tub may seem like a simple task, there are some important things to know before turning on the faucet. In this blog, we’ll go over some tips and tricks to help you fill your spa the right way and avoid any potential problems.

Fill Your Hot Tub at the Filter Cartridge

The best way to fill your hot tub is at the filter area, as this helps to prevent air locks and ensure a smooth start-up. You can do this by removing the filter lid and taking out the filter, then placing your hose into the filter well and filling your spa. Watch the water level and, when it reaches the correct level, take out the hose.

Water Level

While every hot tub has its own ideal water level, there are some basic guidelines you can follow to ensure you fill your hot tub correctly. The water should be 3-4 inches above your filter, cover the jets and any sensors, and be below the pillows to avoid rotting them out. To be certain, it’s always a good idea to consult your hot tub’s owner manual. By following these simple rules, you can achieve the perfect water level for your hot tub.

Use a Pre-Filter to Fill Your Hot Tub

While it’s not necessary for filling your hot tub, using a pre-filter on your garden hose can help start your spa with cleaner water. A pre-filter is a device that attaches to your hose and filters out impurities such as dirt, sediment, calcium and metals from your tap water. By using a pre-filter, you can reduce the amount of start-up chemicals needed to balance your waters chemistry.

Run A Timer

To avoid overfilling your hot tub, consider using a timer. After measuring the time it takes to fill your spa during the initial filling, you can set a timer for that duration on future refills. By using a timer when filling your spa, you can save time and effort, and prevent water waste and overflowing. This is a simple and effective way to ensure that your hot tub is filled to the right level every time.

Add Your Start-Up Chemicals

After filling your hot tub, add a clean filter and balance your water’s chemistry. Remember to keep your spa cover open for at least fifteen minutes after treating the water with chemicals.

With these tips, filling your spa will be a breeze. You’ll avoid common problems, save resources, and enjoy a cleaner and safer hot tub. Remember to fill your spa at the filter area, use a pre-filter, run a timer, and add your start-up chemicals. Happy soaking!
