Closed horizontal loop pressure
Just had our 12 month system check. We have a closed horizontal loop. At what loop pressure would you consider increasing the pressure, and what would you set it to?
The tech said that he would not increase the pressure if the reading was 40psi or more (it was in the mid 30's.) Do you agree with this? He raised the pressure up to the mid 50's. Low 60's is probably our max since our pressure tank (for our potable well water) is set to that. Thanks
