Spa Not Heating in Rancho San Diego, CA
Spa Not Heating is one of the more common calls we get from Rancho San Diego homeowners. A spa that will not warm up usually traces to a stuck diverter valve, a heater fault, or an automation setting. Rancho San Diego runs on Otay Water District at 16 gpg, which is very hard water. Around here that means very hard Otay Water District water scaling equipment, plus aging polybutylene pool plumbing, and it shows up in problems exactly like this one. The pros we work with cover Rancho San Diego and can usually get out within the week.
