I returned today because customer is still having height pressure issues. Informed the customer we would have to go to the next step of replacing the thermal expansion tank. Gave customer estimate. Customer approved estimate. I took the old thermal expansion tank out and installed the new one with a mounting bracket. I also add a hose bib in the crawl space to check the pressure coming in from the street due to them not having a hose bib before the orb in the home. I tested the system and system is working properly with no leaks or issues. The next step if the pressure keeps reading that high would to be to replace the flo by moen.
