Rip all the pipes out and replace then with pex. Summer of 2020 we had our rental house worked on, one of the things done was we replaced all the steel and pvc pipes with pex, then this winter it got down to -10f. All the pipes froze. When they thawed, no leaks. If that pvc froze it would have shattered, as pvc has no freeze resilience.
Disaster averted.
