Spa Bubbles Greatly Reduced

Just serviced my Sundance Denali 680 and now the bubbles seem to be diminished. Used to be so fierce and churning that you could not see the bottom of the tub. Now it’s pretty tame.

    Kent the most common reason for diminished flow would be a soiled filter. Trying running the spa without your filter for 2-3 minutes and see if that makes a difference. You may also check the pump impellor to make sure nothing slipped by the filter and has clogged the impellor diminishing your flow. The Denali has the large diverter jet so make sure that is closed if you want flow to the other smaller jets or visa versa and make sure your air controls are turned on. Make sure all the smaller jets are rotated to the on position. If all else fails contact your local Sundance Spas Support Desk to book a diagnostic and repair of your Denali spa.
