is there any impeller left in there?
My mistake. I should have mentioned that I recently replaced all the pump seals, and the pumps are in apparently perfect working order:
-
Is there a pump fitting adapter to stop this inlet leak?

is there a siphon operating
Hmmm... I'm not sure I understand the question. For equipment, there is only:
a) The filter pump (& the filter & the plumbing to and from the pool)
b) The main drain (& the safety drain on the wall nearby)
c) The debris canister (& the plumbing from the main drain and to the filter pump)
There is certainly nothing that is "apparent" as a siphon; but I agree, it's strange for a pump to be able to suck water through air for as long as I've tested it (at least fifteen minutes at a time).

For the third one, liquid food coloring, or other non toxic dye, released near the area in question can indicate flow / no flow towards any specific drain.
Ah, that's a GREAT idea! I will try. It may be hard to photograph, but I'll let you know how well it works out.

Did the system ever work properly?
Yes.

Did the problem happen after another event?
I'm not sure. It hasn't worked well since the spring re-opening. But it may merely have slowly deteriorated over time.
mas985 said:
Are there two pumps in series (booster usually is)?
None of the three pumps are in series.
1. Filter pump (1.65 HP, pulls water from drains, filters, pushes back through walls of the pool & spa)
2. Cleaner pump, aka booster pump (1.65 HP, pulls water from skimmers, pushes back unfiltered thru popups)
3. Spa jet pump (2.0 HP, only used to bubble water, and is not related to these questions)

Do the heads pop up with all zones?
Nope. That's the main problem. Some don't pop up. Others are anemic.
mas985 said:
Are all the heads installed?
Yes. All 15 heads are in place. They used to work, so I know they're the correct heads. I removed about four or five, in sequence, one at a time, and put them back in the same holes because nothing was wrong with them, so I didn't bother removing the rest, as the pop-up heads do not appear to be the problem.
mas985 said:
You only mention pressure but is something not working?
My mistake. The pop-up heads are not sweeping the debris to the deep end of the pool to be picked up by the main drain. The problem is some are spurting out water weakly, others are strong, and some aren't working at all. Since there isn't any vacuum for a self-cleaning pool, what's not working is the (supposedly) self-cleaning system. I'm trying to debug why it's not working, and, I see nothing overtly wrong
except the pressure
at the water valves is only 8 psi when it should be 20 psi. Calling Paramount, they say the pump might not be developing pressure - so that's why I ask how to test the pressure of the pump (which appears to be otherwise working just fine).
mas985 said:
It is likely the port that you are showing in the picture is below the pool water level
Hmmm... that
does make sense. I had not thought the opening was below water level (it's right about
at water level, so I'll measure somehow and report back. That does make sense though.

Question #1 matters because I'm trying to debug why the cleaner system isn't working well.
Question #2 matters because you can't debug that which you don't understand.
Question #3 matters for the same reason; I can't debug why the cleaning system is anemic if I don't even know whether the drain on the wall below one skimmer feeds the filter or feeds the cleaner pump (or both).
