As a matter of fact city water pressure has been noticeably low, especially at the kitchen faucet. The toilet flush hasn’t seemed very vigorous either (I use standard brass pressure regulator at campground standpipe connection). The trailer city water connection itself was loose and leaking last trip, which I was able to stop by tightening the built-in 1/2” hex. Could too much torque on this cause an issue? Anyway, for now I was able to complete the winterization and (slowly) pump the antifreeze into the port… the fresh and washout ports flowed as they should. I will check valve settings again (exercise them?). I’m still relatively new to Oliver but the system is behaving as if there is a restriction & that needs to be addressed prior to dewinterization & reuse. Appreciate the feedback.

2019 LEII. Have completed Oliver winterization procedure to the hand pumping of antifreeze into the city water port. Hand pump works fine but the connected CW port refuses to accept antifreeze. Wash station cold faucet is on and on at handle. Have double checked valve configurations. Applied enough force to cause house to separate at connection. Could this be a stubborn check valve not opening at low (hand) pressure? Have not yet proceeded to fresh water and wash out ports. Thank you
