Hi Scott, first WELCOME TO THE FORUM!!!!!
Here's a couple suggestions for ya, you didn't say where
you are from so I peeked at your profile and it says
you're from S Carolina.
When is your "average" last freeze?? You can look this
up online or call your local agricultural extension office.
You might be past the date this year???
I'm in the same boat as you. We're going camping next
week but our last average freeze is 6 weeks away so
I will re-winterize when I get home. A gallon of pink
RV antifreeze from Walmart is about 4 bucks.
Watch out, those turkeys have 2 brands. A "house"
brand and a name brand. The name brand is a buck
more per gallon and it's exactly the same stuff.
Just be sure it's RV/marine antifreeze and you'll be fine.
There is a continuous discussion about how to winterize.
Some say blow it out, some say use your RV water pump
to pump the system full of RV antifreeze.
I prefer the pump method because I can do that just
as fast or as easy as I can drag my compressor out
of the garage and blow it out. Also I'm pretty sure blowing
my trailer out does not get every drop out.
You may be fine either way, it's a judgment call.
Either way don't forget to
drain your water heater
and Put it in Bypass when winterizing!!
And Be SURE your water heater is full of water
and out of bypass
before you plug in or fire it up.
Also we suggest making up a signature line here with
your location. Don't give us your full address but a city
state and preferred handle (name) would be great.
Also include your trailer model so we can be specific when
we offer all this free advice
Happy Camping!!!
