hi folks. i bought a coil of flexible PVC hose here for my tub install, and soon after happened to see a small tub plumbed entirely with vinyl tubing. i read up and learned that vinyl is PVC, so their heat rating is the same. the vinyl seems easier to work with and less expensive; some even have a braided structure to stay round. is there another reason the less flexible "flexible" stuff is preferred by pool and spa builders?
similarly, is there any reason to avoid rubber hoses?
