My father just purchased a new house, and it has a pool (built in 2003).
I have turned him on to the BBB method and he already has his TF Test Kit.
I was looking at his equipment pad and could use some help understanding the valve/cleaner setup.
He has the Hayward Aqualogic automation system.
The oddest thing about the setup (to me anyways) is that the pool only has a single pump (there is a pool and spa with spillover). It also has a Polaris 280 cleaner, but no booster pump.
Here is a picture of the equipment pad:
The suction and return valves are clear. The pipe on the far right is for the blower (not pictured).
1) I'm fairly certain the 3rd auto valve right above the pump is for the Polaris 280. My guess is that it closes off the water to the cartridge filter and routes it back through a small canister filter (you can see the pressure gauge on top of it) and to the Polaris 280. When I tried to turn on the cleaner, I got a message on the Hayward remote that said something like "cannot execute command due to interlock". Does that mean that there is some setting that prevents the cleaner from coming on when the pool is in normal filter mode? Why wouldn't the automation system just stop the pump, rotate the cleaner valve and kick on again? I read the manual for the Hayward system, and I do not understand what "interlock" means when they use that term.
2) If you notice the position of the return valve on the left, that is the position for pool mode. There is no spillover mode - there is only pool and spa (the way it has been set up). When in pool mode, someone has set stops in the valve so that it does not go all the way to 100% returns - it stops where you see it in this picture so you get some spillover and some going to the returns. It is a sheer descent as opposed to a cascade, so the aeration doesn't look like it would drive pH up drastically to me.
Is there a reason the previous owner didn't choose the setup mode that allows you to have pool, spa and spillover mode?
I don't see why only having a single pump would prevent us from changing to this setup. I would change the stops so that the valve rotated the whole way.
Thank you for any help/advice!
