My failure at winterizing

This was my first winter at winterizing an AS, after two decades of winterizing boats. I failed.
I did not blow out the lines and I did not pump pink af through the lines. I opened all of the drains and left all of the water valves open. In getting everything ready today, I found two places with cracked plastic: the toilet water valve and the outside shower fixture. After seeing how that toilet valve is a natural low point I am going to need to blow it out in the future. The shower was simply a mistake in that I forgot to leave those valves open.
Looking for leaks I also found that the factory had not tightened the cap on the freshwater pump inlet filter. Easy to rectify.
Total cost of repair parts about $60 over the web and I am smarter now.
Larry

Well, that's not a big loss, Larry. The only thing is to make sure that there are no more leaks, especially before you take it out to travel. Test everything.

One year I did not properly drain the shower wand/handle, and a short piece of copper split lengthwise. Not a big thing to fix, but unfortunately, it was behind the bath tub, so I got to see what else was back there, and took the opportunity to remove/refresh the bath tub's caulking.

Needless to say, I'm a lot more careful now!

Larry,

I made up a combination blow out connection and pressure test tool. It allows you to connect the air source blow out the lines then close all valves in the AS charge with say 30 PSI, close off the ball valve of the tool, note the pressure reading on the tools gage. Check several hours or the next day. Did it hold PSI? This is similar to how a new construction home plumbing system gets tested. The nice part is the air if you have a leak, doesn't make a mess.

What kind of compressor do you have as the air source?

Larry,

Just a simple oilless utility compressor. It does have a regulator.

I got rid of compressors except for tire fill years ago. What I have has no volume. The thing about that water valve at the toilet is unless you press the pedal down while blowing air or pumping pink, you will not push water out of the low point.

Good idea, blow through the city water connection!

All is well

Finally got all of the parts and fixed everything, pressure tested with city water, no leaks.
The guy at the local RV place told me that they sell a lot of toilet water valves as a result of freeze damage. Crummy design that does not allow simple draining to protect the part.
I bought some fittings to put air pressure in the city water connection with a Schrader valve for my tire compressor. I will try to see if it gives me enough volume to blow that fitting out, along with the rest of the piping. If not, it is easy enough to disconnect the discharge hose and blow it out.
ready for the camping season!
Larry

I think that toilet valve is made that way to sell you a $50 part for a $200 toilet. I think if you remove the hose from the valve and drain it, you might be ok with that. It being a low point is a bad thing. My was bad from freezing when I bought the trailer.

this was my first year owning an RV and winterizing.....I just bought the winterizing kit (with the valve and extra-tubing)....and pumped the pink stuff through all lines etc...it took all of about 5-10 minutes....

im very risk averse so I opted for the pink stuff for peace of mind....I know folks blow out the lines, but im so very comforted with the pink stuff in all of the lines (including all 4 low point draines and outside shower and p traps, etc)...

Hope you get it all fixed back and ready to roll soon!

Here is my winterizing failure. Does anyone know how to fix it or where to get the parts? I assume it froze. It is leaking where the pex tubing comes down at an angle.Click image for larger version

I assume there was still some water in the "y" and it froze and broke. Maybe next winter I will disconnect the "y".

You will most likely find that the whole y assembly has to be replaced but it is an easy fix. The parts are available at any RV parts department and it is best if you just take it off and show them what you need. My leak showed up last April on my way south. We used water from a pop bottle for flushing until we got to a place where it was warm where I did the fix in about 10 minutes. I think they have changed the design so the new parts are not so inclined to split. Jim

That is correct. It is actually the flush valve that is activated by the foot pedal. I will have to travel 70-80 miles north to Southaven, MS yo get the part. I will also have to have the pex crimping tool and the little bands. That is not exactly how I envisioned spending my Saturday, but I have no choice.
