Any idea where the fill valve is on a 2013 3725 RL?
In the spring fill the fresh tank and drain a few times while running all fixtures flushing out the antifreeze.
After you deem it good enough, fill tank again adding a cup of blech (to sanitize). Run all fixtures till you smell bleach. Let sit 1 day. Drain tank and refill while running a few tanks of fresh water though all fixtures.

Note:IMHO The line that is between the fresh tank and the pump does NOT get winterized using the on board winterizing valve. This line is flexible and sags along the way and water will collect in the low spots and freeze.[/QUOTE]
