"BEWARE! I had an inground pool and spill over spa installed this summer. The project in question stretched painfully over four to five months despite timely payments, raising initial concerns about the contractor's management skills. It appears the contractor, Carlos, simultaneously juggled multiple projects--likely in an attempt to secure more business--which translated to delays and compromised focus on this particular job. After the pool's completion, I discovered a variety of defects requiring repeated repairs. These included bulging and loose liners (3x) just one week post-install, plumbing problems, excessive leaking from the pool heater, and untidy workmanship such as messy silicone application around corners and stairs. What exacerbated the situation was the contractor's poor customer service. When approached for assistance, Carlos responded with rude behavior and a lack of professionalism. Instead of honoring the warranty he advised to go on youtube. Do not use"

Pool and Spa Servicing questions, answered by experts

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

Regular water testing, filter cleaning, and chemical balancing are essential for keeping water clean and equipment functional.

It’s less expensive to leave your hot tub on all the time, though you’ll want to keep it at a reduced temperature. How much you use the hot tub is also a factor. You’ll want to keep it at a constant temperature between 80 and 95 degrees Fahrenheit for weekly or daily use, then bump it up right before you get in. If you don’t plan to use your hot tub that often, you can turn it off as long as there’s no risk of freezing.  

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. 

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.

Shocking your hot tub means adding extra chemicals to the water. Most spa experts recommend doing this once a week for proper hot tub maintenance, but you can do it more if needed. Shocking has multiple benefits, including preventing the water from becoming murky and it’s essential in removing harmful bacteria from the water.
