      ***Note I temporarily stopped leak by shutting off the valves to the lines effected. Water heater was not lit when I arrived attempted to light it. Pilot fired up but when I turned the water heater on it shut off throwing a low voltage thermocoupler code**** 14 port Viega mani lock with atleast 4 1/2” connections leaking. I believe due to it not being supported for atleast the 5’ I can see. Additionally they installed an expansion tank on 3/4” pex with no support and it has sagged and at some point will burst. To properly work on the maniblock the water heater must be drained and removed. Currently it is not wokring so it should be replaced. Repipe the expansion tank back in with copper then transition back to pex. Rheem 40gal gas water heater, short is manufactured Dec 1st 2017 and currently out of manufacturers warranty.
