Pool and Spa Servicing questions, answered by experts

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.

Yes, but only if it is a freshwater tub (not saltwater) and if you make sure the chlorine and bromine levels are below 1 ppm.

How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it’s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner’s manual.

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.

Where you drain a hot tub largely depends on local regulations, but you must not drain chemically treated water where it can damage the environment. Direct the water toward a sanitary sewer drain that will take it to a treatment facility. If your lawn has a dedicated drainage area that’s free from plants and foundations, you can likely drain it there. Avoid storm drains, as the hot tub water will enter waterways and could hurt aquatic life. Likewise, do not pour it out directly on any public land or where it can get into your neighbors’ property.
