This may seem a dumb question but I don't want to screw up anything. I have a 2010 Flagstaff Super Classic. I went to install a two way bypass valve on the water pump to winterize the lines using the bypass tube to pull the antifreeze from the bottle. The problem is, I have a 10" water filter and canister blocking the pump. I can get to the pump by opening another panel so I can use both hands to get in there but I'm not sure which side of the pump to attach the valve too. I can see what looks like a activation solenoid with a red and black wire on one side of the pump with water line connected to it. My question is? Is this the intake side of the pump or the outflow side? If it is the intake, I know I have to get the valve back behind the water filter somehow to attach it to this side. I can't see any markings on the pump to tell which is inlet and outlet. Thanks for the help if any suggestions.
