Purchasing Spas A recommendation from Bob - Owner of Royal Spa Corp., who has a Bachelors degree from Purdue's School of Engineering and nearly 20 years experience designing and manufacturing hot tubs in Indianapolis. There is nothing on a spa that requires a computer to operate. The only one who benefits from spa computers is the repairman. Never buy a spa that turns off Stagnant water is usually unhealthy.
Stagnant water requires more maintenance.
Turning a pump off and on reduces pump life. Never buy a spa with a 2 speed pump They are unacceptably noisy when you are trying to relax in the spa at night. They can also be heard inside the house. They cause the water to overheat during the summer time unless turned off during the day. They are expensive to operate.
