Jayco Embark 2023 Water Pressure Regulator User Manual
Water Pressure Regulator
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 fresh water inlet or black tank flush. Water pressure regulators are available to protect your recreational vehicles 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 fresh water 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 fresh water 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 fresh water holding tank which allow water to flow out of the water tank. Occasionally, you may see water coming from the overflow tubes when the fresh water 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 re-start when it senses a drop in the water pressure. The pump is designed for . 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 fresh water supply tank.
NOTE: The water pump switches should be in the OFF position when the recreation for any amount of time.
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 tight-ness. 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.
Water Purification System
The canister filter is the primary filter used for the complete water system. If the water sup-ply has not been used for some time, allow the water to flow for several minutes to flush the system.
- Do not allow water in the canister housing to freeze.
- Remove the filter before using anti-freeze to winterize the system or chlorine solution to sanitize the system.
- Flush canister housing thoroughly before it is put back into service after winterizing or sanitizing.
- For best results replace filter every 6-12 months.
- Do not use carbon cartridges where water is microbiologically unsafe or of unknown quality.
- The maximum operating pressure is 125 psi (8.75 bar).
- The maximum water temperature is 125° F (52° C).
Filters should be replaced at the beginning of each camping season or if they have come into contact with contaminated water. When not in use, the water filter cartridge should be stored out of freezing temperatures. RV antifreeze will damage the water filter cartridge. Filter locations will vary by model. They are typically located in a compartment behind the utility center (if so equipped).
To Replace the Canister Filter Cartridge
- Turn off water supply using two valves located on the water lines on each side of the canister. The water pump should be OFF.
- Place drip pan below filter housing to catch any spillage.
- Press the red button on top of the filter housing to release pressure.
- Using a spanner wrench, rotate the filter housing. Unscrew the housing completely, dump water out and remove the filter (dispose of the old filter properly).
- Clean the inside of the filter housing with mild detergent. Thoroughly rinse and wipe clean.
- Remove the O-ring from the groove in the housing and wipe clean. Coat with petroleum jelly.
- Replace the O-ring in the groove, making sure it is properly seated.
- Install the new filter cartridge.
- Replace the canister housing (hand tightening is normally sufficient).
- Turn on the water supply, turn the pump ON, open a faucet, and check for leaks. Turn the pump OFF afterward
- NOTE: There is no bypass feature on a canister-style water filter. The water filter must be removed before sanitizing or winterizing the RV.
Each new recreational vehicle is winterized with RV antifreeze before it is shipped to the dealer. To use the water purification system, full system canister water lines need to be flushed of antifreeze and then the filter installed in the canister before use. Refer to the manufacturer’s owner’s manual and the label on the water filter cartridge for further information.

- Canister water filter
- Outside shower and quick disconnect hose
- City Water / Tank Fill Valve
- Pump Switch
- Macerator ON/OFF switch
