As mentioned in another thread, i recently purchased a house and i'm in the process of opening the pool. I'm in the midst of the SLAM process. reinstalled all of the components and everything has been up and running perfectly. That being said, i still have some confusion as to the setup of my plumbing with regards to the valve right after my SWG Cell. Below are several pictures and i'm trying to understand the purpose of this valve and why it is set up the way it is. Pictured, it is open. Water is flowing to my deep water return (i dont have a main drain in the deep end) and my jet returns. When i close the 'blue' pipe water stops flowing to my return jets, but i can't really tell if anything changes with the deep water return (i've never swam in the pool otherwise i could probably just feel what is going on). Alternatively the way it is set up i can close the 'red' pipe, which i would assume would block all flow from the SWG and heater and entire pressure side of the pool and i can't think of any reason why i would want to do that, much less why it would be safe with the pump running. I cannot close the "green" pipe as it is currently configured. My current theory is that the "green" pipe is heated/chlorinated water coming from the SWG going into the booster pump for my pressure side cleaner. In that case, would turning off the blue valve be something i would do it get more pressure to the pool cleaner? Furthermore, even with that scenario being the case, why would i ever want to turn off the flow from the red pipe. everything is buried so its a bit confusing. i've asked a few friends with pool's and so far no one is certain.
My setup is as follows:
4 return jets on the opposite end of the pool from the skimmers. one return jet on the long side of hte pool plumbed to the booster pump to which shoots higher pressure water once the 'pool cleaner' switch is activated.
2 skimmers in deep end.
Hayward super pump
hayward swimclear filter
polaris booster pump
I appreciate any insight someone can provide
