Join us as we get into the details of this well-designed fresh water system, which is a key part of what makes the Jayco Eagle Fifth Wheels the best RVs on the market.

Fresh Water System

All water contains contaminant and mineral particles that can cause fresh water system odors. Untreated well water is a major source of water system odors. The fresh water (potable water) system needs periodic sanitization to take care of all the components in the plumbing system to discourage the growth of bacteria and other organisms that can contaminate the water supply.

WARNING

• DO NOT drink water deemed microbiologically unsafe or of unknown quality.
•  Avoid traveling with full fresh, black or grey water holding tanks. The weight of holding tank contents in not calculated into the RV cargo car-trying capacity. Traveling with full tanks could cause you to exceed the individual tire ratings and/or the RV GAWR or GVWR. Traveling with full tanks can also affect your vehicle handling characteristics.

Do not remove the potable water label from your recreation vehicle. You should use a non-toxic drinking water hose dedicated only to supplying the recreation vehicle with fresh water. To reduce the chance of contamination, prevent the non-toxic drinking water hose from coming into contact with the ground.

NOTE: If needed, sanitize the water system prior to travel.

Water Pressure Regulator (customer supplied)

CAUTION
A water pressure regulator is recommended to prevent damage to the plumbing system or components. To prevent damage when using the city water connection, a 45 lb. (315 KPa) rated water pressure regulator is recommended. Excessive pressure from the water supply source may be encountered in some parks, especially in mountain regions when using the freshwater inlet or black tank flush. Water pressure regulators are available to protect your recreational vehicle’s plumbing system against such high pressure.

Fresh Water Holding Tank

• Do not cap, block or modify the fresh water tank overflow tubes in any way. Enough water pressure can build up during the filling process to damage the plumbing system if the overflow tubes are obstructed.
• Be careful not to overfill the freshwater holding tank. It can pressurize the tank, causing leakage and water damage and void the warranty. DO NOT leave the tank unattended while filling.

There may be several ways to fill the freshwater tank depending on the model. For details of each method, refer to the Utility Center or Water Connection section. There are plastic overflow tubes in the freshwater holding tank which allow water to flow out of the water tank. Occasionally, you may see water coming from the overflow tubes when the freshwater holding tank is filled. This is normal and can be a result of the recreation vehicle being parked on an incline, or the motion caused by starting or stopping during travel.

12-volt Water Pump

There must be sufficient 12-volt DC power to run the water pump when your recreation vehicle is not hooked up to city water. Once activated, the water pump (also known as the demand pump) will self-prime, and provide water. The water pump continues to run until maximum pressure is achieved and shut off. The water pump will automatically restart when it senses a drop in the water pressure. The pump is designed for intermittent use only. Using the pump continuously or with high pressure will shorten the life of the pump and is not covered in your warranty. Some cycling may occur, depending on the volume of water being released. The water pump is engineered with a check valve to prevent water from back flowing into the freshwater supply tank.

NOTE: The water pump switches should be in the OFF position when the recreation vehicle is left unattended for any amount of time.

Maintenance

Periodically check the in-line water pump strainer for accumulated debris. To clean, shut off the water pump, unscrew the clear cap, remove the re-useable metal strainer, clear any debris, then reinstall. Normal pump maintenance consists of checking and cleaning of the strainer, normal sanitizing and winterizing and occasionally checking all plumbing hardware and fittings for tightness. Lack of sanitizing can lead to premature pump failure and poor performance over time. Scale build-up on the diaphragm and valves, can cause low flow and leak back (occasional pump cycling with no faucets open or tank filling up when hooked up to city water). For additional information on the care and operation of the pump, read the safety and operating information in the pump manufacturer’s owner’s manual.

Water Pump Switch

Most water pump switches illuminate when the water pump is activated. Typical switch locations are in the back of the unit or on the monitor panel, or the switch may be art of a touchscreen system (if so equipped). When the water pump switch is ON the pump runs until 45 lbs. of pressure has been achieved. The red light will stay on.

Draining The Fresh Water System

Water tanks may be drained through a valve located near the tank. A recreational vehicle with a demand pressure pump system will have low-point drains attached to the water lines (normally located near the water tank). These low-point drains will release water in the supply lines by opening the valves and all faucets. The water heater has its own drain plug.

To drain the permanent fresh water holding tank and supply lines:

1. Turn the water heater power OFF (turn off the electric and LP gas switches).
2. Open all faucets, including the outside shower faucet (if so equipped).
3. Open the “fresh tank drain” valve. Methods to drain the freshwater tank may vary by model. Fresh water tanks can be drained by one of the following methods:
4. A white plastic drain is attached to the exterior wall.

Exterior Fresh Water Drain

• A valve located inside the RV adjacent to the water tank (turn 45° to open or close).
• Pull the white “T” handle on the fresh water holding tank to drain the water.
• Low point drains are installed at the lowest point of the water lines. A label is placed on the outside of the RV to indicate where
  the drains are located. The type of drain may vary by model. You will have either an interior or exterior drain.
• Interior drains: the drains will need to be operated from inside the RV. Once the label is found on the exterior sidewall, the drains will be found at a corresponding location in the interior.
• Exterior drains: Open the “low point drains” by removing the black screw on caps on the water lines (coming out from the underbelly). The drains will typically need to be opened from outside the RV.
  
• Drain the sink by removing the drain cap.
• Turn ON the water pump and allow it to run as needed.
• Open all faucets, including the outside shower faucet. Make sure the “water heater bypass” valve is open.
• Operate the toilet flush lever until water stops flowing.
• If the RV water heater has bypass valves, set them to the BYPASS configuration (refer to the Water Heater Bypass section).
• Relieve the water pressure using the P&T valve BEFORE removing the water heater drain plug. If there is any water pressure present, the water will spray out of the opening when the drain plug is removed.

It is normal for some liquid to remain in the fresh water tank after drainage procedure. When you are finished draining the fresh water system, reverse these steps and, dump the grey and black water holding tanks at an appropriate facility or according to local public codes.

Utility Center (P2.5) (if so equipped)

The Utility Center is located in an exterior compartment and allows you to perform the following functions:

• Power fill the fresh water tank for remote or dry camping
• Use the pump to supply water to fixtures from the fresh water tank
• Use the pump to siphon fill or sanitize the fresh water tank from a bucket
• Connect to city water at the camp site to supply water to RV fixtures
• Winterize the plumbing lines and fixtures
• Rinse the black tank to help control odors and prevent waste buildup
• Connect up to (3) coax lines with SAT, CABLE and AUX
  • SAT input is wired only to the wall plate for the satellite receiver.
  • CABLE input is wired only to the wall faceplate at the main TV. The face-plate can switch between CABLE and the outside HDTV antenna (Refer to Section 11 Antenna System).
  • AUX input is wired to wall faceplates of any other secondary TVs in the RV (i.e. bedroom or exterior). This AUX input is designed for use with an outdoor portable satellite dish system mounted on a tripod.
