Hello all... well, I just began the process of re-plumbing my pad. I'm updating all my equipment, so I thought it would be a good opportunity to change the pad plumbing from 1.5" to 2.0". The plumbing had been re-done years ago when the previous owner relocated all the equipment from the basement to outside (yes, the pool apparently emptied into the basement at some point). So I just cut all the lines and decided it would be a good opportunity to send my borescope down to see if the original plumbing was 2". To my surprise (and disappointment) I think I discovered flexible PVC... can you confirm? If so, am I in trouble? it looks like it's only in the pool return line, but it's hard to send my borescope around a 90 degree elbow. Thanks in advance for your help.
