Howdy, have lurked but never posted. Have 3/4 copper coming into house as supply. I will be locating a softener (have not purchased yet) in my pool pump house. In order to do so, I must run a line out and back from under the house. Hard to say how many feet each way, but probably around 30 feet on each leg. When it emerges from the crawlspace it will be under my deck then into the poolhouse. Is there any significant disadvantage in using sched 40 pvc 3/4" to create this loop? Note that I live in Savannah, GA so freezing weather will not be a major issue. I was probably going to go clack but now they cannot be sold over the net I guess...so will probably get a fleck.
