After a number of years of not turning on the spa, I tried it and found that it does not pump the bubbles. The water flow through the nozzles is fine. Here is what I have tried. 1. New filter. 2. drained spa to a level just below jet. Turned on spa to fill and it started normal bubbly operation. Runs fine until turned off and then on and again no bubbles. 3. Cut off the double ell on top of air pipe and can see water down at spa level. Put leaf blower over the 1 1/2 inch air pipe and sealed around leaf blower tube. Turned on leaf blower and spa, nothing happens. It never had a regular blower mounted. So probably didn't need one. 4. There is a 1/2 inch pipe flush with the deck right beside the Spa. It has water in it but attempts to flush it out and snake it to no avail. I have no idea what this is hooked to if anything. The last time the spa worked normally was probably 4 or five years ago prior to removing the old gas heater and before I installed the new equipment.
I think I saw on some pool jet diagrams for spa nozzles something that looks like a double pipe with one being the air and the other water going into the nozzle. Could it be that the air pipe has cracked, leaked water and that is why the jet and the blower will not clear it enough for the air to do its job? The spa has four nozzles and it appears that they are connected in pairs. When I put the pool vacuum hose over one nozzle the adjacent one has a strong water intake.
Is there any other reason the spa will not work properly?
Regarding water chemistry, I usually have no problem. Only when I turn the pump off and leave for a couple of weeks. In the Florida winter I only run the pump one hour a day. During the summer a couple of hours depending on how much rain we get. I get the water tested at the pool store about once a month and buy a jug of chlorine. The tablets usually do a pretty good job. I use a couple of ounces of algaecide once in a while but generally have no problem.
