Winterizing Park Trailer; With Holding Tanks - Jayco COVE 2002 Owner's Manual

To empty tank:
1. Place park trailer as level as possible to make drainage easier.
2. Attach a flexible sewer hose to adapter and secure with a clamp.
3. Remove cap and attach adapter onto valve housing.
4. Turn adapter 10° to lock onto pegs.
5. Place other end into approved sewer system.
6. Open the 3" drain valve to drain the sewage tank.
7. Open the valve on the gray water tank to utilize the water to wash and rinse the hose.
All drain pipes have a "P-trap" installed into each line. Water in these traps prevent odors from
escaping into the park trailer. It is possible for water from the P-traps to spill and permit odors into
park trailer. These odors come from food particles decomposing in the tank. By adding water and
using a park trailer approved deodorizing agent, the contents will dissolve faster and will keep the
drain lines and tanks clean and free flowing. Chemicals are available at a park trailer or RV supply
store.
Most states and parks have strict laws and regulations to prohibit dumping of wastes of any kind into
anything other than proper disposal facilities or sewer systems. Almost all privately owned parks
have either a central pump facility or offer a lot hookup of sewage.

WINTERIZING PARK TRAILER

If your park trailer is not occupied during the winter, it is very important for most states and Canada
to winterize the trailer. Failure to prepare the trailer for freezing temperatures will cause supply lines
and the water heater to freeze causing breakage. Repairs due to freezing are not to be covered under
the terms of your Jayco Limited Warranty.
There is no commodity or product that can be added to the fresh water systems to ensure freeze
protection while the system is in use, other than RV antifreeze. Do not drink water that contains
antifreeze. This includes non-toxic RV antifreeze.

6. For trailers with an optional residential toilet, pour antifreeze in the bowl after the water has
been removed.
