90° brass fitting leaking?
« on: March 12, 2024, 03:51:13 AM »
Hi all, had a 1 in 90° breast fitting leaking connected to my supply PEX line. Cut it out and replaced it, my question is how do these systems prime as far as does the pump reprime the whole system after a certain amount of time running or do you have to force water back into the line with garden hose connected to ball valve fitting in basement? Only about a quart of water came out when I cut the line so it makes me think I should not have to refill but when I did that the opposite line (do you return line) would not fill with water but I'm also unsure of if it was because the thermostatic valve would not open because so much time passed that the water cooled off?
