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.

Without the by-pass line you will not be able to properly winterize your RV using antifreeze. You will have ZERO water to the hot water lines without the bypass line. If you winterize before closing off the water heater then you will need to use an extra amount of antifreeze to fill the water heater before winterizing the hot lines. If you remove the lines you will STILL have two fittings and THEY can leak (much more likely to leak than the PEX tubing is). I'd leave it alone and use it as designed but it's your call.
