Bought an air inflator today and started pressure testing the pex system. There were a few obvious leaks and they were fixed by tightening some fitting. Pressurised the system to 75 psi which is a lot more than the operating pressure but is what’s recommended. I’ll check back tomorrow and fingers crossed it will be at the same pressure give or take a few psi to account for changes in ambient temperature and pipe expansion.
I’ll update this post tomorrow evening with the results. Fingers crossed.
🤞🏼
