We provide the most thorough winterization. We check all zones for leaks or bad heads as we blow all of the water out with compressed air. After the water is removed, we blow out all zones a second time with a mixture of non-toxic antifreeze and natural lubricant. This helps protect the vinyl and rubber seals in your system over winter. Finally, we winterize your backflow preventer or well pump then place a winterized tag on the valve or power source.
