Homes and pipes in Grandview
The original houses date mostly from the 1950s and 1960s. That generation of plumbing brings galvanized steel supply lines, cast iron stacks, clay or cast iron laterals and a lead-caulked joint or two. Many have been partly updated, so the basement ceiling shows copper in one bay and galvanized in the next. The new custom homes that replaced some bungalows are a different story, with PEX, ABS and backwater valves built in from day one.
In older homes, a narrow galvanized line from the street can be the reason the upstairs shower barely trickles while the basement tap runs fine.
Common plumbing calls here
- Galvanized lines restricting flow and rusting at threads.
- Old clay laterals with roots or broken sections.
- Cast iron drains cracking under basement floors.
- Water service upgrades to copper or PEX during renovations.
- Toilet and tub replacements in original bathrooms.
Read water line replacement if your supply from the street is still galvanized or very old, and sewer camera inspection ahead of buying or gutting a post-war bungalow.
Seasonal issues
Older bungalows have shallow basements and less insulation, so pipes near the front wall can freeze in hard cold. In spring and after heavy rain, older sewer connections without a backwater valve can let water back up through the floor drain.
