Water heater valve

I winterized my 5er for the first time. I was going to check to see if it had bypass valves to pump antifreeze in the system and found it was missing a valve.

Is there any reason why they would put a valve on the cold and not on the hot line?

Just a two valve system.
It will work fine.
Check valve in the other line .

Looks like blue, cold is close to the floor. Its common to install a check or non return valve preventing water from entering the hot connection to the heater, therefore a 3rd valve is not necessary.

When it gets warmer I will put the valves in bypass and filled the lines with water. I will verify the water heater doesn't fill up with water. It's not that I don't believe you guys but I always like to see for myself!

Mine only has the shutoff for cold supply. To winterize the system I have to open the two hot and cold valves on the outside shower. The nozzle shuts off the flow and it is the furthest downstream in the system. With this configuration I can then run pink through all hot and cold systems. At the end of the procedure I press the nozzle valve and pink that shower line. The heater is just drained while shutoff. You don't want pink in the heater, it is a bear to flush.

Good chance to inspect/renew the tank annode. With the cold inlet closed, no water should come from the heater with the bypass left open. This will allow water from a hose to fill the cold system and cross over to the hot side. The heater check valve should keep the tank from filling (out the annode plug).
