Galvanized and Cast-Iron Plumbing in Older East Hill Homes

Quick answer: Many older East Hill homes still have some galvanized steel water pipes or cast-iron drain lines. Galvanized pipe can corrode from the inside and reduce water pressure, and cast-iron drains can crack or rust over time. Have the plumbing checked during your inspection, camera-scope the sewer line, and budget for updates if the original pipes are still in service.

Plumbing is one of those systems you can’t see much of in a showing, but it’s often where older homes surprise their owners. Here’s what to look for on East Hill.

Galvanized steel supply pipes

How to spot it

Galvanized pipe is dull grey steel with threaded fittings at joints. You’ll usually see it in an unfinished basement, near the water heater or where the water line enters the house. A magnet sticks to it, which helps tell it apart from copper or plastic.

What can go wrong

• Low pressure. Corrosion builds up inside the pipe and narrows it. Weak flow at upstairs fixtures is a common sign.
• Discoloured water. Rusty or brown water when a tap first opens can point to corroding pipe.
• Leaks. Threaded joints are often the weak spots.
• Mixed systems. Many homes have been partly updated, so you may find galvanized pipe hidden behind newer copper or PEX.

The usual fix

Replacing galvanized supply lines with modern piping is a common upgrade in older homes. A plumber can often run new lines through basements and walls with limited openings. Pair it with other work, like a kitchen or bathroom renovation, where you can.

Cast-iron drain and sewer pipes

How to spot it

Cast iron is heavy black or dark-brown pipe used for drains and the main stack. Look in the basement where the stack drops and heads toward the street.

What can go wrong

• Rust and scaling on the inside that slow drainage;
• cracks, especially along the bottom of horizontal runs;
• rust stains, damp spots or odours near the pipe.

Cast iron can last a long time, so age alone isn’t a reason to replace it. The condition is what counts.

The sewer line to the street

Older homes may have original clay or cast-iron sewer lines running under the yard, and mature East Hill trees mean roots are always a possibility. A camera inspection is money well spent on an older property.

It helps to know who’s responsible for what. According to the City of Vernon, the property owner is responsible for clearing blockages in the sanitary sewer service line all the way from the house to the City’s main, including the part on City property. The City repairs the portion on City property if there’s structural failure such as a collapse, separation, reverse grade or root intrusion. If you ask City crews to respond to a blockage and they find no failure on City infrastructure, you pay the costs.

What to do as a buyer

1. Ask about updates. Has the supply plumbing been replaced? When? Are there receipts or permits?
2. Run the taps. During a showing, open an upstairs tap and flush a toilet at the same time. A big pressure drop is worth noting.
3. Book an inspection. Your inspector will note visible pipe types and signs of leaks.
4. Scope the sewer line. A plumber can run a camera and give you a video of the line’s condition.
5. Get a quote if needed. Before you remove subjects, get a written estimate for any replacement so you can negotiate with real numbers.
6. Call your insurer. Insurers often ask about plumbing type and age. The Insurance Bureau of Canada notes that upgrading plumbing may help reduce premiums, and suggests considering a backwater valve.

If a home’s plumbing is very old, it’s reasonable to have your plumber check the materials in the water service and inside the house.

Selling with older plumbing

If you’ve already updated the plumbing, keep the invoices handy for buyers. If you haven’t, a recent sewer camera video and a plumber’s quote can keep a deal moving. See my page on selling your East Hill home for more.
