I've taken over maintenance of my pool and have tackled so many issues to this point. I'm now focusing on my in-floor Caretaker cleaning system and trying to get it to work properly. I just replaced the valves at the pool equipment as I don't think they've ever been changed in 8-years. I then used the special tool to remove and inspect a bunch of the in-floor cleaning heads. Some had little rocks stuck in them so I picked them out and cleaned them. No apparent plastic damage and the grooves look in great shape. Here are my questions:
1. When I put the heads back into the floor, do they need to go in a certain direction? I'm guessing all the heads are working in unison to push the debris a certain direction at a particular time. Is this correct? Am I over-thinking this?
2. Should the system leave behind dirt in corners? It seems to on mine, but of course i just changed the valves and will see going forward.
3. How many hours per night do most people run their Caretaker unit?
4. Does the diverter in the skimmer have anything to do with the performance of this? I have 2 pipes in the skimmer, I believe one comes from the main drain (and/or) hot tub drain and the other returns to the pump.
