Just wondering what people have in their homes with respect to water piping? There are probably 5 major types we might see in Calgary - my 1955 bungalow is all copper (sewer as well). When I rebuilt my second bathroom 8 years ago I went all copper there as well - did the work myself.
5 common types as best as I can figure are copper, galvanized steel, PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride) and PEX (cross-linked polyethylene) which consist of PEX-A, PEX-B and PEX-C.
