CUSTOMER STATED : Tankless water heater needs servicing. TECHNICIAN NOTES : Out today for the concern of the homeowner wanting to perform a tankless flush on their Rinnai unit located in the garage. While performing flush, I found the cold service valve to be defective causing water to continuously run into the unit with the water turned off. Tried turning water off at the meter, however tankless flush pump was pushing water back through the house with the service valve still being opened. Tankless cannot be properly flushed until cold side service valve is replaced on tankless. RESOLUTION : Did not complete tankless flush. New service valve is not on the van, therefore homeowner would like estimate to replace cold side service valve sent to their preferred email in the pinned notes. Collected membership fee for todays visit. JOB NOTES : Check collected for payment. JOB STATUS : Job not complete ESTIMATE NOTES : Please forward. This is a complimentary service estimate
