Winterizing for first time

Winterizing 1998 U270. Have drained and blown out system with compressed air. Manual says to pump antifreeze through tap on manifold block. What do you pump with? Secondly, what are the parts for connecting the water heater connections at top of manifold block to by pass hot water heater?

I have thought of buying a shure flow pump, mounting it on a piece of wood and using it to feed the pink stuff to the manifold. Could also be used to add water to onboard water tank from 5 gallon jugs when boondocking.

Lots of threads here on Winterization.

New to me 2003 U320 to Winterize or NOT

Here is a reference document for the process.  Pay particular Attention to the drinking water filter, Ice Maker and Washer/Dryer. You hook up a line to the input side of the water pump, put the tube into a 5 gal bucket with RV Antifreeze. It takes 6 gallons or so.  Continue to ask questions as they arise.

I first drain everything using the curb side valves near the water manifold and dump black and grey.  Then remove the plastic plug from the water heater (make sure electric and propane switches are off).  Replace plug when all water is drained.  I bought an electric pump with garden hose connections.  I pump 15 gallons of pink stuff into the water fill port.  (Close the water drains first or you will need 30 G of the pink stuff 😡)  Tilt coach to curb side. Turn on water pump and 10 gallons will go into water heater before pressure builds up.  Then I run all faucets hot and cold until straight pink comes out including washing machine and toilet. I then pour an addtional gallon of pink in washing machine and spin it out.  1/2 gallon in each trap for good measure.  I know this is  overkill, but $50 worth of RV antifreeze is very cheap insurance.  In the spring I recover the 10 gal from the water heater using a pipe nipple with a hose barb and store for next season.

Make sure you get pink through the toilet wash out handle too (if equipped with one).
