Tip A little bit convenient.......

I purchased our trailer new late in the season and used it a couple of times before I put it up for winter.
I de-winterized the following spring, checking everything out, and all seemed good.
We pulled it from Whidbey Island to Mount Lassen, Ca, to meet our kids that came up from SoCal for a week.
I noticed some water on the floor by the toilet.
I messed with it, thinking where the supply line connects to the valve inlet but couldn't get it to stop leaking, so we had to keep shutting the water off to the trailer when we didn't need water.
I determined that some water must have not drained out and must have frozen up in the valve that caused a small crack in that "plastic" valve.
I ordered one but it would have to wait until I got back home.
First trip of this year, I de-winterized and all looked good.
Got to the campground and we were on our own water tank and pump, no water hook-up available at this campground.
It was raining pretty good the first night and my wife noticed water on the bathroom sink counter top.
I thought oh no, not a roof leak, as I went to check it out, but I saw where the water was coming out from under the single handle lav faucet, again, PLASTIC, and I told her we would just have to turn the switch to the pump off, and back on when needing water.

So, when I got home I ordered a new lav faucet and not waiting for the kitchen faucet to do the same, I ordered a better kitchen sink faucet with pullout spray. Not much room to work, had to mostly just feel with my hands, but I got them off and the new ones in, THEN..... I cut off those crummy crimped pex to IP fittings and put on shark-bite supply stops where I can now shut off each line to the faucet or toilet without effecting the rest of the plumbing if need be.
Oh, and I carry an extra toilet valve too, they are pretty cheap, but the new replacement ones now say they are "frost proof" so I guess they knew something was sketchy with it to begin with.
Hopefully this mod will make trailer life a little easier when those cotton picking nagging little things happen on the road....

Just thought I'd share that with you all and maybe save you some grief in the future.

OK..... another picture too I guess.

Here was our spot on the beach where my lav faucet took a dump (no sewer hookup either) on our first trip of the season.

When winterizing We use compressed air at low pressure and l blow out all the lines and valves. I go through the rig while the air is on and I cycle all valves Faucets. once complete I leave all valves open, I remove the shower head and the spray hose head from the bathroom sprayer. Other thing I do is unhook the lines to the pumps. All of this allows for room should a freeze occur it gives room in the lines for expansion helping to eliminate broken pipes. I only put anti-freeze in the traps and toilet bowl.

I have replaced all faucets with brass units with Chrome outer cases no plastic.

I must confess you go way beyond me, GREAT JOB. We rarely get that cold, maybe a day or two that stays below freezing as I live on the water and it seems to keep us warmer than just a few miles inland. Now I must admit I do pull all the hoses off my boat motor and use air to push out any trapped water on the motor.
