Water Purification System

The canister filter is the primary filter used for the complete water system. If the water supply 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 the 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

  1. Turn off the water supply using two valves located on the water lines on each side of the canister. The water pump should be OFF.
  2. Place drip pan below filter housing to catch any spillage.
  3. Press the red button on top of the filter housing to release pressure.
  4. 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).
  5. Clean the inside of the filter housing with mild detergent. Thoroughly rinse and wipe clean.
  6. Remove the O-ring from the groove in the housing and wipe clean. Coat with petroleum jelly.
  7. Replace the O-ring in the groove, making sure it is properly seated.
  8. Install the new filter cartridge.
  9. Replace the canister housing (hand tightening is normally sufficient).
  10. Turn on the water supply, turn the pump ON, open a faucet, and check for leaks. Turn the pump OFF afterwards.

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.

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:Jayco Alante 2023 Water Purification System User Manual 02
    • A white plastic drain is attached to the exterior wall.
    • A valve is located inside the RV adjacent to the water tank (turn 45° to open or close).
    • Pull the white “T” handle on the freshwater holding tank to drain the water
  4. 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.
  5. 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.Jayco Alante 2023 Water Purification System User Manual 01
  6. 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.
  7. Drain the sink by removing the drain cap.
  8. Turn ON the water pump and allow it to run as needed.
  9. Open all faucets, including the outside shower faucet. Make sure the “water heater bypass” valve is open.
  10. Operate the toilet flush lever until the water stops flowing.
  11. If the RV water heater has bypass valves, set them to the BYPASS configuration (refer to the Water Heater Bypass section).
  12. 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 freshwater tank after the drainage procedure. When you are finished draining the freshwater system, reverse these steps and, dump the grey and black water holding tanks at an appropriate facility or according to local public codes.
