Plumbing in Oshawa homes
Neighbourhoods around downtown and the old industrial areas have modest brick and frame homes from the 1910s to 1940s, with galvanized supply, lead services in some cases, cast-iron stacks and clay laterals. Postwar bungalows across central Oshawa often have original plumbing. North Oshawa’s newer homes have PEX and sump pits.

What to check in an Oshawa house
Test the foot or so of pipe ahead of the meter for lead. Look for rust on galvanized lines. In bungalows, check whether there is a backwater valve, especially if the basement is finished or used as a unit.

Local note. Before anyone digs near the property line, Ontario One Call locates buried utilities. The city or region owns the sewer and water connection past your property line, so ask them first if the trouble is out at the street.
Common questions
Should I replace galvanized pipes before selling?
Buyers and insurers increasingly ask about them. Replacing them can remove a negotiation point.
