WINTERIZATION AND STORAGE SECTION 8
Grey Water Holding System
Before performing this procedure on the optional grey water holding system,
your boat should be pulled from the water. Winterize the grey water holding
system only after you have winterized the fresh water system.
Refer to Section 4 - Grey Water Holding System for a description of your boat’s
grey water holding system.
There are two types of grey water holding systems: the standard system and the
overboard discharge system.
Standard Grey Water Tank System
1. Empty the grey water tanks as described in Section 4 - Grey Water
Holding System. Remove as much of the fresh water used in flushing the
tanks as possible.
2. Turn the Accessory Battery master disconnect switch to the “ON” position.
3. On the Safety Breaker Panel, switch the Auto Sump - Forward circuit
breaker “ON.”
You must use a nontoxic, non-alcohol, RV-type (pink) antifreeze in your
boat’s grey water holding system. Using the wrong type of antifreeze can
damage the grey water holding system. The repair of such damage is
not included under the terms of the Carver Limited Warranty.
4. Pour 3 gallons of nontoxic recreational vehicle antifreeze through the shower
and each sink drain.
5. When you remove your boat from storage and prepare to use it again:
a. Pour 5 gallons of fresh water through the shower and each sink drain.
b. Empty the grey water tanks as described in Section 4 - Grey Water
Holding System.
c. Charge the grey water tanks by adding deodorizer. Use the brand of
deodorizer recommended by your Carver Dealer.

System. Remove as much of the fresh water used in flushing the tanks as
