Where is the Water Heater Bypass Valve On an RV?

A question I get quite a bit on the “water heater” question is, where is the water heater bypass valve? There are a couple of different ways to answer this question depending upon your particular make and model of RV. Some RV owners have never heard of this thing called a bypass valve…so if you haven’t heard of it here’s some information on it for you. On the other hand, some RV owners like to brag that they “always” have hot water, even when they “never” go anywhere without a shower. So now you know!
