Where is the low point drain & how much?

[mamentt]

I have a SV264 2010 model, and was looking for the low point drain. I assume it is the pipe under the trailer near the fresh water intake near the kitchen door? First time for me to winterize.

I was going to try the pressure winterize method this year to remove the water from the pipes.

Question, how much antifreeze should be put in the gray and black tanks?

What RV antifreeze flows into the black tank when I winterize the toilet is enough to keep the dump valve from freezing shut.

What RV antifreeze flows into the gray tank from dumping straight RV antifreeze into the traps will do the same for your gray tank dump valve(s).

Oh, these are the low point drains.

Thanks for the picture, I assumed right this time. But, I wanted to be sure.

Besides the 2 low point drains shown similar to the photo in Lou's post, there is probably a drain for your fresh water tank.

If you are going to blow the lines, the 2 low point drains should probably be capped during that process. That allows you to pressurize the system, and then blow through each valve at each faucet. With the caps removed, all of the pressure will go out the low point drains.
