Can I raise the alkalinity in my hot tub?

• <div><p>Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.</p></div>

How do you refill a hot tub after winter?

• <div><p>To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. </p><p>Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.</p></div>

Pool and Spa Servicing questions, answered by experts

Yes, hot tubs are meant to be kept on permanently. It takes more energy to ramp up a hot tub when you turn it on, so leaving it on all the time is more efficient for your hot tub. You can turn the temperature down if you know you won’t be using it for an extended period of time to save on energy costs.

You’ll know you need to replace the pump in your hot tub if you hear loud or unusual noises when the machine is running or notice a significant decrease in water pressure. A leak or altogether failure of the hot tub may also indicate a problem with the pump, but you’ll need a professional to investigate the source of the issue.

Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub.
