We have just purchased a `20 Clipper Cadet 26CBH and I`m thinking of winterizng because the cooler weather is coming . I`ve looked for the water heater bypass and can`t seem to find it . Our water heater is at the very back of the trailer . I don`t see a bypass when I look in the outside access cover . When I`m in the trailer and look in the rear of the trailer towards the back of the water heater the tub is on that wall . Is anybody familiar with this design of trailer to enlighten me where to find the water heater bypass . I`ve also looked undere the trailer and the bypass is not there either . Help .
