In my attempt to figure out why the filter basket was not "full of water" during "spa mode", I discovered something strange (at least to me).
I had mentioned in an earlier post that during "pool mode", only 1 of the 2 skimmers in the pool seemed to be suctioning properly.
I noticed today that the other skimmer (they are diagonally across from each other on the pool), was operating/suctioning in "spa mode".
This seems very strange to me. This is essentially what "spillover mode" should be doing.
Given how long this thread has been, I am going to just do a quick summary with the picture Randy has made for me.
[1] - actuator valve that turns automatically when I switch from Pool, Spillover, Spa Modes (3 total), drain side
[2] - actuator valve that turns automatically, same as [1] but on return side
[3] - Unclear what this is but it is always closed
[4] - Most likely Pool Main Drain
[5] - Pool skimmer (only one of two operates)
[6] - this is what had been draining my spa and now it seems like it returns to the pool
[7] - Most likely Spa Return
"Pool Mode"
[1] and [2] have handles facing right.
This seems to be operating OK except for the fact that only 1 of 2 skimmers seem to have suction
If [6] is open, the Spa drains, if [6] is closed, Spa is full --> when open in "Spa Mode", and I have the heater on, I feel the warm water coming out into the pool
"Spillover Mode"
[1] have handle facing right
[2] have handle facing left
This seems to be operating OK and the only difference with "Pool Mode" is now the return goes into the Spa, causing a "spillover" effect.
When [6] was also open, the spillover would be less strong as it seems like now it was returning back to the pool as well
"Spa Mode"
[1] have handle facing left
[2] have handle facing left
This seems to be taking water from the skimmer that did NOT work in "Pool Mode" and returning it to the spa.
The strange behavior of:
- Having a return pipe on the spa side to the pool [6]
- Pool Skimmer operates in "Spa Mode" which suggests the pipe to the left of [1] is the skimmer pipe, which then begs the question, where is the spa drain pipe
is basically I guess what I have reduced my original problem/question of "Why does my spa drain".
Can anyone make sense of any of this? Or perhaps there is a small tweak I can make to correct this?
Thank you.
