It's likely that the expansion tank has failed which caused the pressure to rise above 30 psi which caused the relief valve to discharge. What you can do now since nothing is open and you can't get parts is to turn the water off into the system and drain some water out so the pressure drops into the low 20's. If the relief valve continues to leak flip the lever up quickly then quickly back down to flush out any debris under the seat.
