The videos were great at guiding me to the problem with my hot tub. A few entries as to the make and model of my hot tub, and there was the part I needed. A few more entries and my replacement part was on its way. They even had a video with a helpful trick to purge the air from the system once installation and filling was complete. I'll keep this website in my favorites but hope I won't need to use it soon. Perfect for the do-it-yourself fat old bald guy! On 04/16/2026 by M. A. (verified customer)
