This is branford white lowboy water heater and instruction manual says ..one should put union between cold water supply line and blue connector on top of tank ....
I am using connector like this - https://www.homedepot.com/p/1-in-FI...gated-Water-Heater-Connector-173218/306339160
Which steel flexible connector
My question is .. can I put this connector directly on to top of that blue connector ? or I must have a union ?
On hot side I did put a union because I had a union spare ..and flexible hose was little short but on cold side is it MUST?
What will happen if I don't put union and cold side between this flexible hose and blue connector?
my theory is ..less joints are less chances of leaks. @Terry
