Drain Pipes With P-Trap; Drain Pipes With Dry Sealing Valve; Tires - Jayco 2016 White Hawk Owner's Manual

SECTION 7 – PLUMBING SYSTEM
Never travel with full black or grey water holding tanks. This not only wastes your
fuel but depending on the location of the tank(s), it can affect your tow vehicle
handling characteristics.
The weight of the holding tank contents is not calculated into the RV cargo carrying
capacity (this extra weight would reduce your available cargo capacity). Traveling with
full holding tank(s) could possibly cause you to exceed the individual tire ratings and/or
the RV GAWR or RV GVWR. Potential damage to suspension components, such as
springs, tires and axles, could result.
If your RV holding tank(s) are located behind the axles, the weight of the full tank(s) will
reduce the hitch weight. Trailer sway and other handling difficulties can be the result of the
hitch weight being too light.
Dump the gray and black water holding tanks before traveling to avoid carrying
unnecessary weight. If you are dry camping and cannot immediately empty your holding
tanks, reduce your vehicle speed until you reach a dumping station.
Before using the RV or after dumping the grey and black water holding tanks, always add
the proper amount of deodorant to the black water tank to prevent malodors and help break
down holding tank contents (unless winterizing). Follow the deodorant bottle or package
instructions. Driving to a disposal site will normally loosen any accumulated waste debris
or solids from the sides of the holding tanks.
Do not add automotive antifreeze or caustic chemicals such as laundry detergents into
the holding tanks. Although these products may have a deodorizing effect, they may
damage the plastic and rubber parts of the plumbing system or the components.
Drain pipes with P-trap (if so equipped):
The drain pipes may be equipped with a "P-trap" installed to help prevent odors from
escaping into the RV. During travel, water from the P-traps may spill and permit odors into
the RV. By adding water and using a RV approved deodorizing agent you will dissolve
the contents faster and will keep the drain lines and tanks clean and free flowing. These
chemicals are available at an RV supply store or your dealer.
Drain pipes with dry sealing valve (if so equipped):
Your RV may be equipped with a dry sealing valve that prevents the escape of odors from
your waste system and eliminates the need for P-traps. Should the RV drain piping system
become clogged and a mechanical cleanout tool is used to open the drain pipe, it is
important that the dry valve be removed before passing the cleanout tool through the
piping. Passing a mechanical cleanout tool through the waterless valve may cause damage
to the internal seal that may potentially allow sewer gases to escape into the RV interior. A
label has been placed near the location of the waste valve that reads as follows:
