I'm redoing the concrete deck around my gunite pool (built in the early 70's I believe) and now it begs the question: do I replace all my piping? The piping is a black ~1 1/2" plastic piping that appears to be somewhat flexible. I don't have any indication of leaking, but they used galvanized pipe for the actual return jet (24"nipple through the concrete wall with galvanized elbow/T's to connect with the poly pipe) and the metal pipe has some corrosion; the stainless steel hose clamps used to at the galvanized/poly pipe unions are in good shape. Should I not try to fix something that isn't broken or is this the ideal time to upgrade the piping?



Thanks
