Welcome to TFP! It does mess with the eyes right? We're so used to rigid PVC unless there are tight spots or curves that require flex. Does that make the entire project bad though? Let's hear from someone in the industry - @jimmythegreek.
Thanks @ajw22 & @Texas Splash very useful information on that page. Unfortunately my pool contract does not say anything in regards to PVC, Anthony Sylvan is building our pool.
Also When I talk to my PB I want to ask about how he plans to protect the pvc, what type of questions should I be asking?
