Mentone is unincorporated, but the City of Redlands has supplied water to the area for more than 90 years, with some parcels served through out-of-agency agreements that vary by address. A leak in the pipe between the meter and the house is generally the owner's repair. Call the number on this page to be connected with a local plumber in Mentone.

Mentone's water and permit situation
Mentone is an unincorporated foothill community east of Redlands on the south bank of the Santa Ana River, known for north-south streets named after gemstones and as the gateway to the mountains on SR-38. The City of Redlands Municipal Utilities supplies its water, and some Mentone parcels receive Redlands water and sewer case by case through LAFCO-approved out-of-agency service agreements. Your bill shows who serves you. Redlands' Hinckley Water Treatment Plant, which treats Santa Ana River water, sits just north of Mentone.
Redlands reports that its service line inventory found no lead lines and no galvanized lines requiring replacement in its distribution system. The private pipe on your property is your responsibility to check. Because Mentone is unincorporated San Bernardino County, check with the County about the permit for a line replacement; your plumber can help confirm what it requires.

Seasonal notes
Mentone sits at the foot of the mountains, where winter nights can bring frost to exposed pipe at the meter box and beside the house, so wrap those before the cold sets in. In summer, irrigation can disguise a slow leak, so turn the controller off for a day before you decide. After heavy storms, ground near the river can stay wet for reasons that have nothing to do with your plumbing; the meter test settles it. When a plumber does find a leak, ask whether the line is worth a spot repair or has reached the point where a full replacement saves digging twice. On a larger lot, the plumber may also suggest moving the shutoff to a spot that is easier to reach in a hurry.
