How often do I drain my spa?

Sunbelt Spas recommends that you drain and refill your hot tub every 120 days. Do not hesitate to drain the spa more frequently if needed or wanted. (If the water becomes difficult to clean, gritty due to large dirt deposits, clouded with body oils and any other situation that results in hard to maintain water chemistry) See your owner’s manual on complete instructions on draining and filling your Sunbelt Spa.
