Welcome to our forum.
He also said my ozone bulb was burned out. I didn't know they went bad. But he says they should be replaced every two years. I didn't know this. Have any of you ever heard of this? That part cost me $200.00. Everything else was covered under warranty. Thank God. I'm going out there right now to test it out. I'll let you know the outcome. How hard is it to replace the ozone bulb myself?
I tell people to change the UV bulb every 1.5 to 2 years so think of the 2 years as a max time to change. I assume he changed the entire unit for $200 and not the bulb but I'd just look to change the bulb next time or suggest a switch to a CD ozonator (preferably the type that doesn't require a chip change). They're certainly more cost up front but work better (produce more ozone than UV) and typically last much longer.
Also more ozone is not always a good thing, if your spa is not designed for the higher output, most of the ozone will be wasted and it is hard on the cover and pillows.
