Where is the bypass valve located on a 2015 Keystone Courgar 29rli 5th wheel?

The bypass values are usually located behind the water heater. Usually one going to the input and output of the water heater (so 2 valves), and then should be a cross pipe before these with a valve. Summer mode you want the 2 valves to the water heater open, and the one on the cross pipe closed.

Usually close to the water tank, or ask your dealer...

Bay Hill was manufactured by Evergreen who closed operations in June of 2016. Dutchmen purchased one of the Evergreen plants, however it is not known if brand names and/or information was purchased.

Also, please review all component manufacturer's owners manuals ... Call our factory and obtain authorization for repairs BEFORE attempting the repair yourself ...... If thefifth wheel is hitched up with the front too high, too much weight will be.

The only way to turn off the LED light over the pin box is with the remote control.

On some later model Montana 5th wheels, there are actually three holding tanks which will eventually require draining. (two grey tanks, 1 for the kitchen sink(s) and 1 for the bath tub & bathroom sink, and one black tank, obviously the toilet...) The two most used drain valves (1 black & 1 grey) are together in the docking station area where the city water supply is hooked up, the other (kitchen sink) is at the left rear of the coach behind the farthest rear wheel along the frame. (That is where "Keystone" installed the grey tank for the galley, or kitchen if you prefer.)
If certain it is the black tank which won't dump when the black tank valve is pulled, there is a restriction before the valve (or the valve itself is not opening hence a broken cable to the valve?) One might try "snaking" up into the sewer line, measuring the distance from the outlet to the valve location, assuring it is either open or closed. Once that has been determined, you will at that point have to remove the sewer line at the valve for repair. Be sure to wear latex gloves and eye protection and have a drain pan or bucket handy for spillage which can be collected and dumped down your home toilet or outside sewer clean out if you know its location.

Pull switch out and remove both wires from switch terminals. If light goes out, replace switch.
