Re-winterizing

[TomGraham]

Had my Lacrosse TT winterized by my dealer. Took it down to NC over the holidays and used the toilet only. Didn't hook up the water line or run the pump. Dumped water straight into the toilet. When I dumped the black tank I did hook up the flush for it to the water spicket. When I got back to PA I dumped a gallon of RV antifreeze into the toilet and black tank (left some in to help seal it). Should I be doing anything else? First Rv and first post.

You should blow out the flush system you used. But in the case of that flush only you can probably suck the water out with a shop vac. Just hold the hose up to the inlet for a minute. Or, fill the end of a water hose with anti freeze and flow that into the flush system.

If you shopvac has an exhaust port use it otherwise as Evereddie suggested.
