Customers say: Quality work

"????? Reliable, hardworking, and goes the extra mile Domingo with DM North Bay Pool Service has taken care of our pool in Kentfield for over a year and a half, and I can say without hesitation that he is one of the most patient, loyal, and motivated service providers I have worked with. He took on our pool when it needed a full startup ? initial deep cleaning, filter work, booster pump installation, and chemistry rebuild ? and got it dialed in quickly. From there, he handled monthly service consistently, communicated well via text, and always made time to talk through what the pool needed. When we had to pause service for several months while the property sat empty, the pool fell into rough shape ? algae bloom, heavy debris, neglected hot tub. Domingo came back without complaint, brought the right equipment, and restored the pool to swim-ready condition. He treated it like his own. That?s the kind of work ethic you don?t find easily. A few things that stand out about"

Pool and Spa Servicing FAQs, answered by experts

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

You should have your spa or hot tub inspected and serviced yearly to prevent more costly repairs. Regular hot tub maintenance can save money and help keep you safe from hazards such as faulty wiring. Call a professional hot tub repair specialist, who will know what common issues to look for and have the parts and tools on hand to fix them immediately.

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.

If water is left inside the hot tub pump over a cold winter, it could freeze and severely damage the pump, water lines, and jets. That can cause leaks, which require very expensive repairs. Freezing or leftover water can stain and damage the hot tub shell, which leads to replacement. Even in mild climates, leaving sitting water in the tub or pipes for a long period of unuse is a bad idea, since disinfecting chemicals fade and the water can develop bacteria, algae, and other big headaches when it’s time to use the tub again.

Hot tub heaters typically last seven to 10 years, though some might only last five years if not properly maintained. You can maximize your hot tub heater’s lifespan by ensuring the water’s pH level is properly balanced.
