Service tip #2

Service technicians should include a note on their maintenance checklist to scrub off any slimy bacteria (biofilm) appearing on hot tub walls, so it does not continue to circulate in the water.

Service tip #3

One should also make a note of the installation date and any hardware changes or major repairs on the customer record. Many newer hot tubs come from the factory or have options to add secondary disinfection devices, which can help improve the water quality and lessen the amount of maintenance work. This being said, these devices require regular upkeep that is often overlooked, such as replacing solarized ultraviolet (UV) bulbs, or replacing an ozonator as they have a limited lifespan.

Service tip #4

Create a laminated checklist for new and existing hot tub owners. Many technicians are now leaving a laminated ‘enter-exit-checklist’ attached to hot tub covers. This encourages users to check sanitizer and disinfectant levels as they open and close the hot tub when they enter and exit the vessel. Note, it is important water balance parameters are in range, and enough sanitizer is present in the water.

Service tip #5

Oxidizing with a non-chlorinated shock is very important because those soaking in the spa can excrete up to one pint of fluid every 30 minutes, sweating in the heat of the water. It is also very important to leave the cover off for a minimum of 30 minutes to allow for gas off after adding the oxidizer. Be sure to also use a high quality, broad spectrum enzyme weekly to help maintain a healthy environment. This will also help break down the organics that were introduced for the oxidizers to work more efficiently.
