I have a in ground bar and pool, which both connected to the same pump and cartridge filter tank. Recently I notice:
1. When the pump is NOT running, after 4-8 hours, there seems to be losing about 3-4 inches. I marked the water on the pool, did not see the water level changed there. However, what it means is that when I ran the pump, the water in the spa would be filled from the pool, and therefore the pool would seem to lose some water.
2. If I released the pressure from the filter tank, that is, I opened up the release valve on the tank, then the water in the spa does not go down and the pool water level seems to be same.
3. There is constantly water trickling out from the front house drainage, which is by the pavement of the house's front drive way. There is a hole at the bottom of the cement pavement next to the street.
I already looked at the Jandy valves at the pump and also the one that looks like a Jandy valve without the handle and the cover is a clear cover, and all do not seem to have any crack on the rubber seals. There does not seem to be any leak around the pump area and any pipes that I can visually inspect.
The ground does not seem to have any excessive mud nor overly wet areas around the pool. I also turned off the sprinkler system for over a month already. I already cleaned the filter yesterday and the issue is still there.
So the mystery is why does the spa lose water? why there is water trickling out from the drainage at the front house pavement drain hole? I'm not sure that the pool pipping system is a closed system or is it connected to the main drain? Or is it that there is a leak in the bottom of the pool somewhere which I can't see.
Thanks for any information or suggestion on how to fix or identify this issue.
The Jandy lever at the bottom left is to control the water coming from the pool and the suction of the cleaning robot. The robot uses the same pump as the filter pump. The top left Jandy lever is to control the water from the pool and the spa. The right top Jandy lever is to control the water going out from the heater to the spa or pool. And the right most clear Jandy-like control without the lever is I think to shut/open the water to the spa from the heater and the Jandy lever at its left.
The pool has the skimmer on the ground and the bottom of the pool has another, i believe, a drain. The skimmer has 2 holes, one goes to the pump and the other hole, I'm not sure. The spa has one drain at the bottom and another one about 3 inches up from the bottom, on the side of the seat. There are 4 jet holes on the side of the wall , but one does not seem to spray water and in fact, it seems to suck in water, not strong, but I can feel the suction. I think this hole is plugged. How do I unplug it without having to call a repair man? I have to give this information because it might/might not be the cause of this leak.
