Charlie's Tips of the Week 29 - 44
Archived copies of "Charlie's Tips of the Week" from 1977 to 2012, published in the local Evergreen papers. Some of the tips may not be relative to most of todays hot tubs, (listed by most recent).
"If a wooden hot tub has to be drained for a while, leave approximately 1/2 inch of water on the bottom to minimize the shrinkage of the wood."
"In your hot tub or spa water, bromine is effective as a sanitizer over a wider pH range than chlorine."
"Insulations of the tub, pipes, support equipment can save you money in energy costs by minimizing heat loss."
"If your hot tub is equipped with an air blower, either the motor should be mounted above water level, or the piping loop above water level. This prevents water from ruining the blower motor."
"With wooden hot tubs, it is important to maintain a constant water level, otherwise the wood may dry out toward the top and leakage may occur."
"Because thermostats can malfunction, it is best to check your thermometer before entering your hot tub or spa. This can prevent chilling or scalding experience."
Chlorine and bromine sanitize the contaminants in hot tub and spa water by oxidizing them. Ozone oxidizes the contaminants without the use of chemicals.
"In cold weather, expansion and contraction due to variations in temperature may cause filter lids to loosen. Tighten if necessary to avoid leakage."
"To those of you who choose to "shut down" your outdoor hot tub for the winter, it is essential to have it done professionally, preventing un-wanted broken equipment due to freeze."
"Chemical deterioration of wooden hot tubs may occur if excessively high chlorine residuals are present in the water. The wood surface becomes rough with white fibrous matting."
"The prompt removal of heavy snow from outdoor hot tubs may prevent damage to the tub cover materials and support equipment."
"It is best to dissolve maintenance chemicals in water before adding them to your hot tub or spa. This prevents concentrated solid chemicals from damaging the tub's surface."
"If your outdoor spa has been shut down for the winter, make sure that it is covered completely. Melting snow may cause ice to form in the bottom and damage could result.
"In contrast to chlorine, bromine is an effective sanitizer both in the combined and free form. Bromine also dissipates slower at high water temperatures than chlorine."
My experience has shown that properly insulated hot tub systems break down less frequently since they have less trouble "fighting the elements.'"
"Wooden hot tubs are composed of 50% cellulose fibers which give wood its strength, 30% lignin which acts as the cementing agent for the extractives which contribute to decay resistance."
