2012 Thor Hurricane 32A

While fixing a leak under the kitchen sink I noticed 3 valves. Hot & Cold water shut off's and 1 that tied the hot and cold water together. What is that for?

Hi Captaindon,
The valves are used for winterizing the coach plumbing system. The coach owner's manual or a placard in the coach should explain how to winterize the coach.

Thanks, can't find anything in owners manual, unless that's what they are calling through hot water tank by-pass?

Should be "The" not "through".

This is where the water heater bypass was in my '12 32A. It probably looks like it ties the hot and cold water together because this is where the water enters the water heater for heating. The valve should be on a "T", one way going into the water heater, and another way going to where the line comes out of the water heater. If I remember correctly, mine also had a valve at the connection where the water comes out of the water heater to stop water from back filling into the water heater.

Thanks that is the way it is plumbed.
