Weeping at PRV is an indication that air pocket has been lost......
Pouring out of PRV indicates t-stats have failed to shut down heating.
Normal t-stat is preset to OPEN at 140*F
ECO (high temp t-stat) is preset to OPEN at 180*F
PRV is preset to OPEN at 210*F/150# (resets at 125#)
Weeping is common.......pouring out is not but that is way the PRV is there...safety device to relieve high pressure.
T-stats not held tight against tank wall will not allow them to sense the correct temp.
Best to just replace the set.....clean tank surface before installing new t-stats and make sure they are held tight and connections are clean/tight on t-stat terminals.
