Still on the learning curve of pool ownership. I have well balanced pool water now thanks to this forum but now trying to learn about a few plumbing areas of the pool.
I read a few threads on here about main drains, hoping to learn about how mine works. There is a blocked off pipe in my skimmer, I assumed it goes to the main drain but now I am not so sure. I removed the cap and nothing happened so I attempted to apply suction to it by installing the skimmer plate and I placed a rubber ball on the top so the suction was forced from this pipe only. What came out in the space of 10 seconds was pretty gross (see pic). I emptied the basket and went again but nothing more came out and it is nice and clear the second time.
But my question is this, does this pipe lead to the main drain? How can I check this? I remember during the initial pool handover that the pool guy said the main drain was a hydrostatic valve and said it would allow water to enter the pool if there was sufficient water beneath it to stop the pool from popping out from pressure. Does this mean there is no pipe up to the skimmer and the main drain just goes into the earth below? If so , where could the capped off pipe in the skimmer lead to?
Cheers
