Or the trailer is sitting half a degree out of level and the water you thought was out is in an elbow on the low side/corner.

Or the rv is 8 years old and the well designed, properly installed lines have been distorted because or time or whatever has been stored against them for 8 years. I've seen a lot of lines that are up off the floor.

Blow your lines well or use antifreeze if you are in a freeze area, advice that this is not needed is bad advice.

FWIW, propylene glycol, rv antifreeze, is used in food, medicine, toothpaste so your fear is unfounded.

Where there is a chance of freezing, I would certainly recommend more than just opening up the low point drains as the only activity.

I bought ours used and had to replace outside shower and two different interior elbow joints due to not winterization. The previous owner never used the water system, just what the dealer had done during the final walk-through.

I will be blowing mine out this year (first winter for me owning the PUP) and will then garage it.

I agree that I don't want to put the antifreeze into it at all. But I'll be doing more than just opening drains.

However, I have examined the water lines in my trailer. They do not sag. I can see that if a different trailer has a point in the water lines where it dips down and then rises again the you have something similar to a P trap. You will need to blow the water out of there.

From my faucet to the low point drain, it is all down hill. There is no rise, therefore there is no place for water to collect.

Other Trailmanor owners have discovered that two additional steps are required after draining:

1) turn the pump on momentarily. this will flush what little water is in the pump out of the pump.

2. the outside shower and inside shower spray heads do not drain well remove them.

Water lines in a trailer should never have a low point that can collect water. If they do, then I suggest that it is either a poor design, not properly installed, or the shape of the trailer left no alternative.

I have a hard time believing that doing it my way in my trailer will result in blowing water lines. Doing it my way in your trailer might have that result. Perhaps you have some location in you water lines where the water can collect. There may be a difference in the design between my trailer and yours.

It certainly is safe to use air to blow the water out, as long as the air does not blow the pipes out from too much pressure.

Anything I am not willing to mix with some bourbon is something I am not willing to put into my water system. I have looked at that pink stuff and there is no way I would ever want to drink that stuff, no matter how much it was diluted when flushed out in the spring. I prefer to never have a reason to use it.


Each to his own - My water lines do not sag either, but I will not risk my trailer without antifreeeze. And as far as using air to blow out lines, that too can leave residual water if not done right. Proper flushing and sanitization of the water system when dewinterizing will remove all traces of antifreeze. I, too, do not like pink stuff in my Laphroaig, but I am not paranoid about it - it is not toxic. You are fortunate to live in a warm climate and to be able to store your trailer in a garage. Those of us who leave our trailer outside where the temperature can drop to -20F do not wish to take the risk of not using antifreeze. Storing your trailer in a climate like this and doing as you suggest is pushing your luck - better safe than sorry!

It's unfortunate for the rest of us that Trailmanor is the only perfect trailer out there. Wish we had all known that when we went trailer shopping!

The low point drains on our TT are sticking out of the belly right below the water heater, I just take the caps off and let it open for a day or two, then replace the caps and charge the lines with antifreeze, in my opinion, adding antifreeze is the only safe way to winterize, it does take much water to freeze and break a line.

My low point drains are directly under the kitchen sink...pull up two tabs on the inside of the trailer to open them.

There is another for the fresh water tank also.

Be sure to drain your water heater at the tank. Draining the low points will not empty it and replacing a heater tank costs$$$.

Don't forget to blow out the toilet flush valve. This will not drain on it's own. Need to blow it out while holding the pedal down.

Use the antifreeze. Pump it through the system with the water pump and open all faucets, showers inside and out and toilet valve, until the pink comes out enough to fill the traps. And by-pass and drain WH, leave plug out.

I do not put antifreeze in the FW tank. I drain and blow that out. But I do put some AF in gray tanks and black tank.
