Help! What purpose does this water line serve? Pic included.
Hello. We had to replace our water tank. Now we are wondering if this line connecting the hot and cold water serves any purpose? If not...we will simply remove it.

The water heater bypass is used as follows.
3 ways to winterize, Method 1 (Wet)
Drain the water heater (Outside, remove the plug in the bottom and open the TPR valve at the top manually to drain it) while you are at it flush the thing out (Flush out any solids in the tank) if it's a surburan inspect the anode (Attached to the plug). If it's an attwood, Skip that it does not use one.
Operate the bypass valve so that no water enters the water heater and then pump Pink Stuff (RV antifreeze) into all the lines, forcing the water out.
Come spring you got to flush all that******out of there.
Method 2
Dry method.. I operate the bypass, then blow out the lines, drain the water heater as above.. HOWEVER it is not necessary to operate the bypass. You can drain the water heater, Blow the lines, drain the water heater, blow the lines,
You need to do this about 10 times to be safe.
(Even if you use the bypass you blow out the lines)
TO blow out the lines open all valves and feed the city water connection compressed are regulated to around 50-55 PSI.
NOTE: in this method you do not need the bypass.
Method 3: South, Carolina in my case (Upstate SC, below 1,000 feet elevation, temps get down into the 20's over winter but since the rig is occupied and heated not a problem)
