First time winterizing with Uni-Dock System
Tried to winterize last weekend. Finally located the low point drains behind the panel in the pass through compartment. Set Uni-dock to winterize, attached hose to city water connection and put other end in antifreeze, turned on pump.....nothing. pump was pumping air through the system, not picking up anti-freeze. Located pump, detached pump inlet hose from back of panel, and put in in anti-freeze. Anti-freeze was siphoned into pump and back to panel, then stopped. Nothing into the rest of the system. Called the dealer.....bring it in and we'll look at it. Sorry, unit is parked in RV park and I can't get it out.....Dealer says...sorry,can't help you.
Any ideas? I am thinking of using external pump through city water supply to siphon anti-freeze into the system. It just seems for the price we paid for the RV, the system should work correctly.
