I take it that you are trying to drain your hot water heater? What you've done is simple. When you close the bypass to the WH you will not get water from your WH as there is no water pressure to the WH even if the pump is running. If you want to drain your WH, open the service door on the outside of the coach, unscrew the drain plug and let it drain out. Do NOT do this if the heater is hot. After you drain it, open the WH bypass valve and let water flush out the scale and crud, turn off the WH bypass and screw the plug back in, and check for leaks once you open the bypass valve again. If you are simply draining don't open the bypass valve again.
