Pomona
An old city with older pipe
Pomona incorporated on January 6, 1888, decades before most of its neighbors existed as cities. The Phillips Mansion dates to 1875, the Fox Theater to 1931, and neighborhoods such as the Lincoln Park Historic District hold homes from the city's early decades. That age shows up underground, where some properties still rely on steel supply lines.
The city also has newer areas. Phillips Ranch, built in the hills between downtown and Diamond Bar since the 1980s, is almost entirely residential and faces different issues than the older grid near Fairplex, home of the L.A. County Fair, and Cal Poly Pomona.

Local problems
What we see most in Pomona
Galvanized steel in older homes
Steel lines in early neighborhoods corrode inside, causing low pressure and brown water.

Older service lines can be smaller than today's households need.

How we approach older Pomona properties
In Pomona's older neighborhoods, we often find that the main line has been patched more than once over the decades. Each patch is a joint where corrosion or a loose fitting can start the next leak. When we see that pattern, we explain why replacing the run usually costs less over time.
Older lots can also hold surprises: walkways laid over the line, mature trees with roots along the route, or a meter that was moved at some point. Permits for main line work go through the City of Pomona.
In Phillips Ranch, the conversation is different. Those homes are newer and the lines are usually copper, so a leak there is more likely to be a single repair than a full replacement.

Pomona water line questions
How do I know if my Pomona home still has galvanized pipe?
Look where the line enters the house or near the meter. Dull gray pipe with threaded fittings is usually galvanized steel. We can confirm it for you.
Does it matter whether the city or Walnut Valley serves my home?
Not for the work itself. Both stop at the meter, and the line from there to the house is yours. It only matters for who to call about the meter or street side.
Do you work in Phillips Ranch?
Yes. Phillips Ranch homes are newer than much of Pomona, so the work there is more often a repair than a full replacement.
