I've been pressure testing my PEX rough in over the last few days and I can only assume that I have a leak but I wanted to confirm before considering next steps. I'm using one of these http://www.pascospecialty.com/catalog/PASCO_CATALOG_F.pdf
to check the pressure and I followed Uponor's procedure to prestress at 120 psi for 30 minutes and then brought down to 80 psi. For all intents and purposes it held at 80 psi for 2 to 3 hours. However, over 60 hours the pressure has slowly dropped to 55 psi.
Is there anything normal about this or do I simply have a slow leak somewhere?
Thanks!
