Need help winterizing unusual water pump in Wildwood LA TT

[lopoff14]

We have a 2009 Forest River WILDWOOD LA that has an unusual water pump. None of the "older timers" in our RV resort have ever seen the one in our trailer. The dealers head service guy says not to follow the directions in our manual. He winterized it for us, but that doesn't help us this year as we do not have the proper instructions on how to winterize our water pump (with WaterPur filtration). We have instructions on the removing the filter which we'll follow prior to winterizing...but we don't know where to blow compressed air thru system to clear water out including the water pump. As mentioned none of the old timers knew how either...just scratching thier heads.
Any other owners know how to winterize their (newer) unusual water pump?

I'm not good at winterizing, so I won't try to tell you what to do.
However, before ANYONE can tell you what to do, they'll need to know what brand and model water pump you are using. I'm sure it will help if you can find out and post that information.

in order to Blow out your water you must first open all faucets drains and plugs . also draining hw heater and turn by pass valve .
then buy the air adapter and screw it into your fresh water fill . it should look like this .
