I have been thinking about adding a liquidator to my above ground pool this year and from many of the posts on here I learned that it may be easier to install this if I had pvc piping. Right now I have the flexible tubes that came with the pool when I bought it used from another couple and we have only run it one season so far. I am wondering what would be the advantages/disadvantages to the pvc instead of my current set up? We have no heater or anything just the pump and filter. Thanks!
