Plumbing in Norristown's Older Homes
Norristown has been the Montgomery County seat since 1784 and became a borough in 1812. A railroad link to Philadelphia in 1834 turned it into an industrial center, and by 1900 it had more than 22,000 residents. In the West End alone, about 1,700 buildings, mostly brick rowhouses and twins, went up between 1885 and 1925.
Homes from that era often still have original plumbing. These are the most common problems we find in them:
Cast Iron Drain Lines
Crack or corrode from the inside, causing slow drains and backups.
Clay Sewer Laterals
Joints that let tree roots grow into the line.
Galvanized Supply Pipes
Rust inside, lowering water pressure and discoloring water.
Patchwork Basement Plumbing
Added piece by piece over a century, with mixed materials and old shutoff valves.
Buying an older Norristown rowhome? Ask for a sewer camera inspection before closing. It shows the condition of the line from the house to the street, and a repair found after closing is yours to pay for.
Norristown's Water, Sewer and Flood Risk
Norristown sits on hills that slope down to the Schuylkill River. That location shapes the plumbing problems we see most, from aging service lines to basement backups when the river rises.
Here’s what that means for your home:
Where the water comes from
Pennsylvania American Water supplies drinking water to Norristown Borough.
Where your responsibility starts
The utilities maintain the mains under the street. The service lines connecting your house to them are generally yours to repair, so a backup in your lateral is a job for a plumber.
Flood-prone basements
During Hurricane Ida in 2021, the Schuylkill hit major flood stage at Norristown. A backwater valve on the main sewer line can help stop sewage from backing up into a basement during floods.

Preventing Frozen Pipes in Norristown Winters
Many Norristown rowhomes have pipes running through unheated basements and along exterior walls. Those are the first to freeze and burst when a cold snap hits the Schuylkill valley.
Shut off the main water valve first, then call us at (610) 489-2717, day or night.
Winter Checklist
- Shut off and drain outdoor hose bibs before the first hard freeze.
- Insulate exposed pipes in basements and crawl spaces.
- Keep the heat at 55°F or higher when you travel.
- Know where your main water shutoff is before you need it.

Norristown Plumbing FAQs
Yes. We serve Norristown homes and businesses from our shop on Ridge Pike in Royersford, and we answer calls 24 hours a day, 7 days a week.
The sewer lateral from your house to the main is generally the property owner’s responsibility, while the utility maintains the main itself. A camera inspection shows which part has the problem.
Yes. Much of Norristown’s housing was built between 1885 and 1925, and sewer lines that old are often cast iron or clay, which crack and attract roots. An inspection costs far less than an unexpected sewer replacement.
Stay out of standing water if outlets or appliances are underwater. If a pipe has burst, shut off the main water valve. Then call us for sewer backups and pipe repairs.
Yes. Call (610) 489-2717 any time, day or night, for burst pipes, sewer backups, flooding or no hot water.
