Winterize 2019 R23

[Nickc]

I have a 2019 R23 that I will be winterizing in Bronx NY for my first time. (Boat is presently at slip in Stamford CT & will be hauled on land in Bronx NY beginning Nov). I viewed the helpful Ranger Tug video, but I am looking for more specific info/comments using non-toxic propylene glycol (WEST -60 Antifreeze?) for all systems including: AC, Potable water, black water, gray water, water heater, shower pump and bilge pumps.
Here is what I was thinking;
1. AC system winterize-- Just before boat is hauled out... close sea cock to AC water strainer ... open cap to sea strainer and pour in approx. 2 gal of WEST-60 into open strainer while activating AC until WEST-60 Runs out of side of boat...shut sea strainer valve and shut off AC. After that... open top to AC unit and pour some WEST -60 into condensation pan that is Y joint-connected into V-birth sink...until it exits side of boat. (I think I can do this the same way ... after hauling on land... as long as I close AC sea cock before hauling... and have access to power to plug in on land).
2. For potable Water system winterize... (22gal water tank)—open both H/C cold valves on both sinks and allow tank to empty (until sputters from both sinks). Add 4 gal of -60 to water tank and open both H/C sink valves until pink flows. Turn off water pump.
3. Gray Water winterize—close gray water sea strainer valve... open sea strainer cap and pour in --60 (approx. 1 gal) while activating gray water pump until flow from spray hose noted. Also position marine head lever to suck from gray water strainer & pump head until -60 noted in head.
4. Black Water winterize---run fresh water into to toilet and flush a few times to holding tank and then pump out holding tank… then pump 2 gal of -60 from toilet to holding tank. Toilet is now winterized.
5. Shower pump, all 3 bilge pumps (2-lazarette+ 1 engine pod)- pour -60 (approx. 2 gal) into shower sump and all 3 bilge pumps until -60 exits hull outfall fittings.
6. It appears approximately tot. 12gal WEST-60 required?

Since this is my first shot at winterizing my R23—I would appreciate any comments/corrections/suggestions. Thanks in advance

Solid plan. I use compressed air on the fresh water system. I don’t like the idea of intentionally contaminating my fresh water system every year. For the Air Conditioning, I use a water pump and flow the antifreeze in through the through-hull fitting until it flows out the scoop intake. There is no grey water tank. For that, a cup or two poured into each sink will flow out any residual water in the drains.

My thoughts….

tks for your thoughts...I think also I will be pumping Antifreeze solution into AC outet...like you, maybe next year I will set up a compressed air system similar to the video shown on RANGER TUG/TugNuts web site...

I'm also planning my first winterization, and intend to use compressed air. I no longer own an air compressor, and will need to buy one. Will a small compressor (like a 1/2 HP 1 Gal Makita) handle the job, or do I need a bigger, 6 gal version?

I, too, use compressed air on the potable lines. However, if you don't disconnect the 'bottom' connection to the water heater, the heater will still have about 2-ish gallons, even after properly flushing out your lines.

The first time I pressure-flushed my lines, I - just for giggles - decided to disconnect the bottom 1/2" connection to the heater and the heater drained for about a minute, meaning there was still considerable water in the tank, even after both hot and cold lines were spewing only air.

Also, I will still - after fully flushing the lines with air - put a small amount of antifreeze into the holding tank. Because I can't see how much water is left in the holding tank after the pump starts 'spurting', I feel better putting a little (1/2 gal) into the tank. In spring, it's easy enough to put 5+ gallons of fresh water into the tank and pump it out a couple times. One caveat if you do this is to run cold water only, so you don't push any antifreeze into the water heater.
