Tankless Water Heater in Mentone, CA

Mentone conditions

Mentone is an unincorporated foothill community east of Redlands, on the south bank of the Santa Ana River and at the start of SR-38 into the San Bernardino Mountains. That position brings colder winter nights than most valley towns, and frost on exposed pipes is a real possibility. For a tankless heater, the cold matters twice: outdoor units depend on electric freeze protection, and colder inlet water cuts the flow a unit can deliver at shower temperature.

The City of Redlands says it has provided water to the Redlands and Mentone area for more than 90 years. Its supply blends Mill Creek and Santa Ana River surface water (the Hinckley treatment plant sits north of Mentone), groundwater from wells in Redlands, Mentone and Yucaipa, and State Water Project water when needed. Some Mentone parcels get Redlands water and sewer through out-of-agency service agreements approved case by case, so service can vary by address, and not every property is necessarily on city sewer. The Redlands water quality report lists the hardness; check it or have your water tested before picking scale protection.

Tank or tankless in a foothill home

Signs it may be time

• Hot water output that drops noticeably in winter
• An aging tank with corrosion at the fittings
• Mineral crust on faucets and showerheads
• A tankless unit that faults after cold nights

Timing and permit notes

Install or service before the cold season when you can, so freeze protection and the vent are checked before the first frosty night. Annual flushing fits well into the same fall visit. The permit office for Mentone depends on the job, so check with San Bernardino County about the permit before work begins; the installing plumber can help with that. If you smell gas near the heater, leave the house, then call 911 and SoCalGas at 1-800-427-2200 from outside.
