I have an old Pacfab Bermuda widemouth skimmer (I believe it is still the same as this current Bermuda skimmer), and it has two plumbing ports on it. One is obviously going to the pump, but the other is currently just plugged up. I'd like to have a pipe from that second port run to a port low on the wall and have whatever is needed to "equalize" the skimmer, such that if it ever runs dry, it'll suck from the low wall suction port instead of sucking air into the pump.
I'm not even sure if I'm using the right terms for this, and to also be very clear... I'm getting a new liner put in soon, so I'll (or the PB will) have access to the steel wall to be able to cut a hole and put in some extra plumbing now.
I see two different parts listed on Pentair's website:
Float valve assembly (Amazon link)
Equalizer valve assembly (Amazon link)
Or do I need both of these parts?
