What Is a Hot Tub Line Flush?
A hot tub line flush is a cleaning solution designed to clean a hot tub’s plumbing lines. These lines can accumulate dirt and debris over time, affecting water quality and performance.
Hot tub line flushes, available in various forms, are added to the hot tub water and circulate through the plumbing to break down and remove buildup.
Regular use, ideally every three months or when the hot tub is drained, helps maintain cleanliness and functionality, ensuring clear and clean water. It’s a simple and effective maintenance practice for a well-functioning hot tub.
Why Is Flushing the Lines of a Hot Tub Necessary?
