Just purchased a new spa controller that requires new plumbing attachments into the pump and out of the controller. The 2" flex pipe leading to both ends has hardened and shrunk to the point that installing the new controller with existing piping led to numerous leaking joints no matter how I tightened them. So at least some of this hardened flex PVC has to go. It's a 2003 Hawkeye spa.
Just cut out a section with a hacksaw and the sawdust it produced has me wondering if this hard pipe is even serviceable. See attached image. It resembles some old pool table rails I replaced where the rubber had become hard and brittle over the years. The spiral reinforcement protrudes so that the outer surface is not smooth. Can this still be glued into Schedule 40 PVC fittings with these spiral ridges?
Thanks in advance for any advice you can offer.
