Hi all! I am looking for the possible cause and hopefully even a solution. Knowing the cause however will go a long way in me coming up with a solution.
I have 4 deckjets. They are all on the same leg of plumbing. In addition, they were installed in a loop so that they all receive the same amount of pressure. Off the filter, everything is supplied with a 2.5" PVC pipe. As you can see from the pic below, the first thing it hits is the SWG. The next thing inline is the flow switch. It has plenty of straight pipe before the switch. I then branch off to three returns and the deck jets. Shortly after the 2.5" pipe goes under ground for the deck jets, it reduces to 3\4". That 3\4" is a continuous loop that feeds every deck jet. (Story continued below)
All that being said, they work great. All 4 shoot into the pool in a near identical manner. I can tell Alexa to turn them on, and the automatic valves close off so that the flow is only to the deck jets.
The reason I do this is so my pump doesnt have to be working as hard as it can to supply enough pressure to the jets. When all other valves are closed off and the pump is running at 45-50%, the jets provide a nice arch into the pool.
Here is where the problems start. After 20 minutes or so, Omnilogic detects no water flow an turns off the pump. There isnt any air in the system. The pump basket is 100% full of water. Once the valves open everything but the jets, the pump is happy as a clam again.
Anyone know the problem?
Is it the reduction from 2.5" to 3\4"? If so, can the flow sensor be disabled in Omnilogic only when I am just running the jets?
Is there really a dangerously low water flow going through the pump when it happens or is this a false positive?
Any help on this one would be greatly appreciated! Thanks in advance!!
