Today (11/26/25) heating checks were performed and all filters replaced. All units checked are in service and functioning properly with one exception. One of the four tube heaters at the deep well site was not working when we arrived. I spoke with Cindy about this heater and she directed me to have our dispatcher call to schedule a service visit. All thermostats were set back to their original position after tests were completed. Thank you, Jon and Diego Tech notes: Re-Verber-Rey - M/N - HL3-30-100P, S/N - 15 0005 (not functioning) Clears pressure switch until ignition. P-switch 0.25ic differential 0.35iwc tested on one side.
