Welcome to our forum.
Thanks for the reply.Yes I opened the diverter, took out the parts inside and started the pumps to check that the pumps were working. As I said, the water came out vertically about 2 or 3 foot. I then checked that they were correctly positioned before replacing them as they are meant to be.It really is a problem with the power coming out of the jets.When placing the diverter to the foot jets and turning the pump on, what usually happens is that the water bubbles and almost fountains in the middle of the pool because they are so strong.But at the moment, what is actually happening is that the water just moves slight in the bottom of the spa. This indicates that I have a problems somewhere else.I wonder if the pumps are working at full power? But they are electrical so they really should only be on FULL or off.I don't understand.....
The only valves I know of are the diverters that you use to switch the power between different seats.I have no confidence in the dealer as they have just sent a second technician who yet again said there was no faults.The problem is, the first hot tub was replaced because of this same issue.And having spent hours trying to work this out I can not believe that it is something so obvious as a valve being wrongly positioned. 2 hot tubs with the same problem.Any other ideas?
Sundance and Jacuzzi do not use gate valves. My guess is you put the divertor gate back in wrong or your jets are closed. Not much else it can be unless it's an airlock in your pump? Also if they replaced a spa already because of the same issues makes no sense what so ever..
We have a Sundance Certa, and most of the jets are adjustable. I'm not sure if you mentioned thi, yet, but are you sure the jets themselves are open. Any jet with an adjustable nozzle will open and close individually by turning the trim ring around the jet. They're really easy to bump with your feet or turn when sliding from one seat to another.
You removed the diverter cap and the pump "pushed water 2' to 3' into the air. That tells me the pump is pushing water. IF it is not coming out the jets (??) the jets could be rotated in the closed position.2nd spa with the same problem (??), same owner, same dealer, 2 technicians look at it, try taking your filter out being sure nothing can be sucked into the pump like leaves or toys (??) could that have happened before (??). Run the jets without the filter restricting suction and flow.
The pumps on a new Cameo do not pull through any filter. Have you tried adjusting the air controls? The flow seems much stronger with the air controls open. Also, the foot jets in the Cameo are adjustable and may be positioned straight ahead instead of pointing up.
