2011 26BH fresh tank drain/winterizing question

[hizenberg]

Hello,

I just had a quick question regarding my 26BH. When I first got the trailer this year, we used bleach to clean the lines and when I dumped the fresh tank, I just used the low point drains (two side by side with valves). Now after reading a winterizing guide, I see that I may have a fresh tank drain. At the back near the hot water tank connections/bypass valves, there are two white plugs that appear to go out the bottom of the trailer with two hoses hanging out (no valve or anything on the underside, just open hoses). Do these just press down or is there a turn to release them? Or is that just a safety backup type thing? Or do the low point valves combine the function? The guide indicates I should leave the fresh tank drain open so it can breathe in the winter.

Just watched the PDI video my DW made on our walk-thru and those valves in the rear storage area are low point drains and they pull up. I have forgotten to drain those for two winters now so I'll have to remember them this year.
