Welcome to our forum.
Other than cost savings, is there another reason (e.g. longevity, repair history) that 2 speed pumps aren't used?
My two therapy pumps are variable speed. I absolutely love this feature.I wet tested alot of tubs, and by far I like this feature the best from Artesian.I can dial in my jet pressure just the way I like it, depending on my needs.I'm surprised to see the Optima has only 1 speed pumps.
As stated by those who actually own the Optima with the one 2 speed pump, the 2 speed pump is not really all that necessary for massage
I heard they were very reliable.
