Flushing the Holding Tank


Technical Articles

Tag: head

For what it's worth, here is the recipe we've been using for flushing the holding tank for winter lay-up. We think it is very effective as the last flush is quite clear.

Holding Tank Recipe Ingredients: 
  2 c. Calgon Water Softener (liquid) 
  1 c. liquid laundry detergent 

Add two cups water softener in 1 gal. hot water. Pour/pump mixture into tank. Add one cup detergent to 1 gal. hot water. Pour/pump mixture into tank. Let sit for several hours then top off tank with fresh (hot if possible,) water and let sit for a few more hours. Even better is to sail with the tank full to thoroughly agitate the mixture in the tank. Pump out and rinse/pump with fresh water. 

Tip: Many RV stores carry a wand that attaches to a hose to provide a high pressure spray. Use this in the inspection port of the tank (if you have one) then rinse/pump again with fresh water. You may also be able to go in by removing the vent fitting on the top of the tank.

"Graycruiser" yeah, that's me. 1st Mate, Pattie, and I have been sailing on the Chesapeake for 18 years on charters. We bought our first boat in 2000, a C25 #5909, a 1998 in great shape. After retiring in 2004, we decided we needed a bigger boat and the C320 was just the ticket for our expanded cruising schedule and to accomodate our 5 children and 11 grandchildren. We're love'n it.

Life is better on a sailboat.
