Monte Vista Water District supplies water in Montclair, while the City of Montclair handles sewer, and the line from the meter to the house is generally the property owner's to repair. With a median build year of 1969, many Montclair service lines are decades old. Call the number on this page to be connected with a local plumber in Montclair.

Symptoms of an aging service line
- Brown or rusty water when a tap first opens
- Pressure that has slowly faded over months, everywhere in the house
- A wet or sunken patch between the meter and the foundation
- The meter's indicator moving with all fixtures off
- A water bill rising without any change at home
The Montclair picture
Montclair was built out from former citrus orchards after World War II, and its housing is older than most of the region, with a median year built of 1969. The City itself advises owners of older homes to have a plumber check for problems such as pipe corrosion or lead from old pipes. On a house of that age, the service line may be galvanized steel that has rusted inside, early copper, or a line patched more than once, and each of those changes whether a repair or a full replacement makes sense.
Water and sewer come from different agencies here. Monte Vista Water District is the water provider, and the City refers water quality and main water line questions to the district at (909) 624-0035. If water is coming up at the meter box or the street, call MVWD. The City of Montclair runs the sewer, which matters only if the plumber needs to dig near the sewer lateral.
What the cost depends on
- Pipe condition: corroded steel along the whole run usually rules out a patch
- Length and depth from the meter to the house
- Surfaces to remove, such as older driveways and walks
- Replacing the house shutoff if the old valve has seized
- Permit through Montclair Community Development, Building & Planning, (909) 625-9477
When you place the call
The number on this page connects you to an independent local plumber who works in Montclair; Plumber Riverside CA is a referral line and doesn't do the work. Mention the age of the house, whether the water has been rusty and where the ground is wet. If water is running freely, close the house shutoff first. The plumber can test pressure, look at the exposed pipe and tell you whether the line has more life in it or is ready to be replaced.
