I'm redoing my equipment plumbing and I'm wandering what the stand alone pipe at the left might be for. It's been disconnected - and uncapped -since I got the house.
The equipment piping - coming from the pool also - is 1.5" but the one in question is 1".
Ideas?
Maybe #1: There is a closed port on the middle the my pool that I thought it could be for a suction side cleaner but upon testing that port is dead. Could it be that this pipe is the missing piece to close the loop? If so, is it normal for that pipe to be 1"? Is this a common - maybe outdated - practice in pool building? How I can I test this if the pipe is connected to the port? One idea is to use a drain snake and see if it comes out of the pool port (not sure if it is long enough). Any easier ideas?
Thnx!
