WHY WOULD ANYONE USE FLEXIBLE PVC
The answer is simple. Its quick and easy. A pool builder can save hours per pool by using flex pipe. While this is great when it comes to speeding up the process, it is not great for the long term of your pool project and the potential headaches the use of flexible pvc can bring to you as a pool owner. Another reason is skill. Quite simply it takes more skill to properly plumb a pool with rigid pvc and there are alot of pool builders that just dont have it. Lastly it could be lack of knowledge of your pool builder. Maybe they dont know they are using an inferior product by using flex pipe. Maybe they don't know the pros and cons. If thats the case, should they really be building your pool!
