System type: ICS system
System is not working.
ICS is fine. Freeze valve is defective. Stared constantly leaking several years ago. Client called local agency that installed the system and was told to turn the isolation valves above the tank. This isolated the ICS unit from the auxiliary water heater. This occurred 2 years ago.
Left the client – adult sibling – my card and told him to have his father call me. States that father was going to replace the auxiliary water heater in the near future. Doubts that he will re-plumb tank to solar system. Informed him that he should get a new freeze valve and keep the solar system.
Insulation tape is deteriorating.
