De-winterizing 303RLS

[merpmerp]

Your water heater may be in bypass mode, On mine I have to open the inlet and outlet valve and close the bypass valve.

Thank you for mentioning this. Can you tell me where the bypass is located? On my old class c is was right by the water tank but I don't even know if I can access the water tank from the inside.

There was an issue with the water at the campground last weekend so I didn't de-winterize yet. I'll probably get to do it next week.

I should have looked, but can you get to the water tank from the inside on the 303? Is the bypass located there or on the control panel outside?

What year is your 303 ? Maybe you shared that somewhere but I did not see that. You may want to add that to your signature and profile page to help with future questions and resolution.

Early year GDRVs 2014-2015 (or through 2016 had the Kantleak) panel and later years have the Nautilus. Which panel do you have ?

It's a 2019. If you can point me in the right direction I will add signature information!

Thank you

Both the Kantleak panel and the Nautilus panel control water heater bypass. There is no need to dig in behind the panels .

For the Nautilus, it is the red valve . . . see Howard's explanations of each mode in post 1 of this thread https://www.mygrandrv.com/fo...755#post199755

You can see other things which can be done too. I am not certain what can or cannot be done for you as a registered guest vs a paid site sponsor. A moderator can help with this.

We are not full time so our 303 is usually in storage for about 4 months +/-. I elect to do annual preventative maintenance, dewinterize and sanitize and wash the 303 in the same day/weekend. We stay in several areas throughout the spring, summer and fall where we are utilizing the Fresh Water tank and I like to make sure the water tank and lines are clean.

If you have a washer prep (but no washer) and/or outside spray/shower ports remember to also run fresh water through those to clear out any antifreeze. Surprising how long the antifreeze taste lasts when you forget about those "not often used" lines.

Hope this helps

Crap - forgot to do the spray ports yesterday. Thanks for the reminder...

I always drain my hot water heater and leave the plug out. I will replace the plug and the caps on the lowest point of my water lines (below the hot water heater on the bottom). Then I'll pull up the tab on the pressure/temperature valve and wait until water runs solid out of the heater before closing the valve. Only then will I cut the switch to the hot water heater on.

Thanks .... Great advise I used this weekend. That plastic plug sure hard to get in without cross-threading ,,, took my time and was patient.

If fitted - clothes washer prep requires a short piece of garden hose and bucket to flush

YMMV but I like to add some RV drain valve lubricant to each tank and toilet when de-winterizing.

Hi MarkDeb,

I used a garden hose for this a couple weeks ago for the first time. In the past I used a small container under the drain fitting. On my unit, the fittings are so close together, and so low to the cavity where they sit, that it was a bear to get the hose on and off. Do you have the same issue?
