De-winterizing - 2018 Lexor TS

Spring is finally here and we're ready to de-winterize the fresh water system on our 2018 Lexor TS.

As with any of the information on this blog, we're not professionals so, take what we say with a grain of salt and consult the manuals for your specific RV before proceeding.

The procedure is pretty-much the opposite of the winterizing process we wrote about in this post: Winterizing - 2018 Lexor TS


Supplies we used were a drinking water safe hose, glass measuring cup, bleach, phillips head #2 screwdriver, and an RV Water Filter.

We broke out a new Camco RV water filter for this process.  We use these for a season and replace them annually.

There's great debate over whether to put the filter close to the faucet, or at the tank end of the hose. We fall into the faucet camp thinking that it will keep the hose as clean as possible.

To freshen the water system, we add 1/3 cup of bleach into a gallon of fresh water.

That's all the bleach we use.

It is NOT 1/3 cup of bleach per gallon of tank capacity.
Before proceeding, check the valves under the van to insure they are all closed.

Here are the three low point drains in the closed position...
...and the fresh water tank drain valve in the closed position.
Now we are ready to add fresh water.

Open the fresh water door and  put a little filtered water in.

Next, pause to add the gallon of diluted bleach.

Finally, continue filling until the tank is about 2/3 full then replace the cap and close and lock the door.

Moving inside the van, take a look at the plumbing under the galley sink. Check to make sure all the fittings are connected.

We unscrewed the hose just before the water strainer last fall and it hasn't yet been reattached in this photo. It would be easy to miss without looking closely.

After snugging the hose on by hand, the fit now looks good.

Next, turn the pump on and watch for leaks.
With the pump turned on, run the cold water until the pink anti-freeze is out of the line.

Again, check for leaks under the sink around the pump.
Now move the handle to run the hot water line until it runs clear.

Note that it won't get hot yet. We will work on the hot water system later in the process.
Moving to the bathroom, depress the  pedal to flush the pink anti-freeze out of the toilet bowl and lines.
The valve should work freely and the water run clear.

The bathroom sink should be run on cold and again on hot until the pink is gone.

By this time, the smell of bleach should start to replace the smell of anti-freeze.

Don't forget to also run the shower attachment until the anti-freeze is gone from that line.

Ours shower head is an after-market replacement with a metal hose. You may have a plastic hose and shower head.
For those of you that made it this far, here's a bonus. Fellow Pleasure-Way owners Trish and Duane told us about this suction cup soap dispenser. It has held on for over 10,000 miles so far, but can be easily released to clean the counter.

Search Amazon for "Cuisipro 13.2-Ounce Foam Pump, Chrome" if you would like one. They were $12 last time I looked.
Back to de-winterizing, it is time to move outside and run the exterior shower until both the cold and hot water run clear.
With that pink stuff out of the pipes, now we take care of the hot water system. Our unit has a Truma AquaGo Comfort Plus.

Twist the top knob a quarter turn counter-clockwise to open the water heater compartment.
Find the water filter. We tucked ours in the lower right corner last fall when we winterized.

Pull the yellow lever out and down after releasing the black tab right above the word "Caution."
With the yellow lever down, insert the screen end of the filter into this round opening.
Orient the filter so the word "TOP" is on top and the pins drop into the slot on the yellow handle.
Gently return the handle to a closed position. The black tab should click over the top when it is locked in.

Back inside the van, remove the four phillips head #2 screws holding the panel that hides the water valves.
Here you can see the valves in the winter position. This bypasses the hot water heater.
Now that the anti-freeze is out of the system, all four valves can be returned to their summer positions as shown here.

Red is hot, blue is cold, and white is the hot water recirculation line. The valve between the red and blue lines is the water heater bypass.
Now, to test the hot water, turn the "LP GAS" switch on.
And turn the Truma Power to On. It doesn't matter if the switch is up or down, as long as it isn't in the center "off" position.
Back inside, run some hot water to release any air bubbles from the system.

Now the AquaGo control can be turned on. Here it is shown in the off position. The detent on the knob is tiny and the same black color that makes it difficult to see.
One click up turns it on.

Run the water in the galley sink and listen for the burner to ignite. Keep running the hot water and it shouldn't be long before you feel hot water coming out of the faucet.

A solid green light means all is well. If the light is flashing, consult your Truma manual for troubleshooting advice.
Next, check the water heater exterior and see if there are any leaks.

If everything looks good, close up the cover.
Turn the latch clockwise to lock the cover back in place.

You should now have a working water system.

To complete the freshening of the water tank and lines, close everything up and take a short drive around your neighborhood. That mixes the water bleach combination and sloshes it around the inside of the tank.

We let the bleach solution sit overnight to help sanitize all the lines, then dump and refill the tank and lines with fresh water the next day.

That's it for the water system. Now take out your maps, find a friend (furry or otherwise) and plan your next adventure. We hope to meet you down the road.


I hope this was helpful. Please leave constructive suggestions in the comments. We're always looking for better ways to do things.
