"Summerizing" my Redwood

[Elliott & Vicky]

As our Redwood sits empty for a lot of the summer, I have been wondering if it is best to keep water in the black water tank to keep what is in there moist. Any thoughts?

[Greg C.]

If you rinsed your black tank thoroughly when you put it away it should be pretty much empty. I usually rinse mine at least twice sometimes more if the water is not clean that comes out of it.

Doubtful you would/could ever drain it completely dry. Leaving a few gallons it shouldn't hurt anything either.

[Elliott & Vicky]

Danny, That's what I have been doing. I'm in agreement that you can't drain it dry, so I'm leaving 5 gallons, 1/2 cup of Dawn, and a bottle of Calgon in it this year.

Here is what we use for black tank treatment all of the time:
HOLDING TANK TREATMENT

Start with an empty Gal. jug
Pour ¼ cup Calgon Bath Beads into jug.
Fill jug ½ full of water (Shake well)
Slowly pour 40 oz. bottle of Pine-Sol in.(Shake well)
Top off the Gal. with water. (Shake well)

8 oz. Black Tank 4 oz. Gray Tank

It works great.
