Never buy a spa that is controlled by a computer!
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 on and off again 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. The newer technology in the spa industry is gradually phasing out the 2-speed pump because of its high operating cost.
Never buy a spa that sucks through the filter!
No correctly engineered filter system sucks through the filter. This type of filter requires considerably more cleaning maintenance and expense. Restricting the water coming to a pump reduces its pumping ability.
