Quick answer
Knob Hill has the oldest housing among the large Colorado Springs ZIPs, with a median home age near 56 years and listings built in 1961 and 1965. Homes that age often still carry galvanized steel supply pipe that narrows with rust inside, so weak pressure at one faucet is usually the first thing we chase.
What 1960s galvanized pipe looks like after six decades
Galvanized steel rusts from the inside. The bore narrows, pressure drops at the far fixtures first, and the threads at each fitting thin until one weeps. Drains from the same era were typically cast iron in the stack and under the floor, and the main shut-off was usually a gate valve that may no longer close all the way.
Patching one galvanized section tends to move the problem to the next fitting. Once three or four spots have failed, a whole-house repipe in PEX or copper is the repair that lasts. We run the new lines, pressure test them before any wall is closed, and replace the main valve while the water is already off.
Clay and cast iron under the yard: the lateral is yours
Colorado Springs Utilities puts the wastewater line from the house to its main on the owner, including damage from a blockage in it. Laterals laid in the 1960s were commonly clay tile or cast iron, and the Colorado Geological Survey notes that swelling clays in the region can disrupt sewer lines. Joints shift, roots find the gaps, and the basement floor drain is where you see it.
We clear the main line first, then put a camera through it so you see the condition yourself. Cracked clay or cast iron rotted along the bottom usually means repairing the bad section or replacing the run, and the video tells us which.
Common jobs
The plumbing calls we get most in Knob Hill
How we handle whole-house repiping
Early-1960s galvanized supply is the most common reason for low pressure and repeat leaks here.
Sewer Line Repair: what it costs and how it runs
Clay and cast iron laterals of this age crack, shift and take in roots.
Sewer scope before buying a home
A camera shows whether an old lateral needs one repair or a full replacement before anything is dug.
How we handle main shut-off valve replacement
Original gate valves at the main often will not close when a pipe finally lets go.
Old copper or galvanized yard lines
Old yard lines, and any lead service line the utility flags, are the owner's to replace.
Gas tank replacement
Rental turnovers are the natural time to replace an aging tank before a tenant finds it leaking.
Rentals, turnovers and the lead service line rule
Only about 54 percent of homes in this ZIP are owner-occupied, so a good share of our Knob Hill calls come from landlords between tenants. That is the right moment to look at the water heater, the shut-offs and the supply lines, while the house is empty and the water can stay off. The south part of Village Seven shares this ZIP and much of the same housing age.
City code in Colorado Springs does not allow lead service lines on the water system. When the utility finds one, it notifies the owner and records that notice each year with the El Paso County Recorder until the whole line is replaced. If a notice comes with your property, we replace the private side, from the right-of-way to the foundation, with a new service line.

FAQ
Plumbing questions from Knob Hill
Find the main shut-off and the lines at the water heater. Galvanized is dull gray steel with threaded joints, and a magnet sticks to it. Copper is reddish and does not hold a magnet. Many houses here have a mix, with copper repairs spliced into original galvanized runs.
Yes, and for a single failure that can be the right call. The catch is that the rest of the run is the same age with the same rust inside. If pressure is already poor or leaks keep coming, repiping the supply in one project is usually the better use of money.
When all fixtures slow at once, and the lowest drain backs up first, the main lateral is the likely culprit. We clear it and camera it so you have a record of what we found and whether the line needs repair.
The utility notifies the owner and records the notice each year with the El Paso County Recorder until the whole lead line is replaced. Replacing the private section to the house clears it on your side, and we coordinate with the utility for the public portion.
