My g/f’s parents are convinced they need a water softener (even though they really can’t afford it) because they believe the salesman who says it will, among other things, help descale the water pipes very very quickly.
Will the water softener actually help descale the pipes? are there any better solutions?
Mississauga does have very hard water. softener is the best solution. you can try inline cartridge type ones instead of a whole house (bigger) at first, and see if it helps.
