Local Knowledge

What Older Denver Plumbing Looks Like

Many central Denver neighborhoods were largely built before 1950, and their plumbing reflects nearly every material used along the way.

Galvanized Supply Lines.

Galvanized steel was a standard supply pipe for decades, and many older Denver homes still have some of it. It corrodes from the inside, so the pipe narrows over time. The signs are low pressure, especially on the hot side, brown or rust colored water after the tap sits, and leaks at threaded joints.

Cast Iron Drains And Clay Sewer Laterals.

Inside the house, older drains are often cast iron, which cracks and scales with age. Outside, the sewer lateral is often clay tile, and every joint is an opening for roots. The mature street trees in Washington Park and Park Hill are the main reason we recommend a camera inspection for any older home with recurring backups.

Who Owns The Sewer Line.

In Denver, the property owner is responsible for the sewer service line from the house all the way to the connection at the public main, including the portion under the street. The city maintains the main itself. A camera inspection showing exactly where a break sits comes before any sewer repair.

Denver Water And Lead Service Lines.

Denver Water supplies the city. Some older homes still have a lead water service line, and Denver Water runs a Lead Reduction Program that replaces customer owned lead lines with copper. We can help you identify the material of your service line and coordinate plumbing work inside the house around that program.

Winter In Older Homes.

Older Denver homes have more plumbing in exterior walls, enclosed porches, and crawl spaces, and many are heated by boilers that sit idle all summer. Insulate exposed lines and have the boiler checked before the first cold night.

What Our Customers Say

Questions

Plumbing Questions From Denver Homeowners

Am I responsible for the sewer line under the street in Denver?

Yes. In Denver the property owner is responsible for the sewer service line from the house to the public main, including the section under the street. The city is responsible for the main.

How do I know if my Denver home has a lead service line?

Look at the pipe where the water line enters the house, usually in the basement near the meter or the main shutoff. Lead is dull gray and soft, it scratches easily to a shiny silver, and a magnet will not stick to it. If you are not sure, we can check it during a visit.

Why is my water pressure low only on the hot side?

In older Denver homes, low hot water pressure often points to galvanized pipe narrowed by corrosion, frequently on the line leaving the water heater. It can also be sediment in the heater or a failing fixture cartridge. We check the fixture, then the heater, then the pipe.

Do you pull permits with the City and County of Denver?

Yes, where the work requires it. Water heater replacements, sewer line repair and replacement, gas line work, and repiping generally need a permit in Denver. We pull the permit, schedule the inspection, and meet the inspector.

Can you work on steam and hot water boilers in older Denver homes?

Yes. Many older Denver homes are heated by hot water or steam boilers feeding cast iron radiators. We repair and replace boilers, service circulators, expansion tanks, and relief valves, and we bleed and balance radiators so every room heats evenly.
