Potable water sanitation and bacteria elimination on the 2023 Jayco Greyhawk Prestige are governed by fresh water holding tanks, 12-volt water pumps, and chlorine-based sanitization solutions.
How to Fix It:
-
Mix Chlorine Solution: Prepare a mixture of household bleach using one-quarter cup of bleach per 15 gallons of fresh water capacity, dissolved in a gallon of warm water.
-
Pour into Tank and Fill: Pour the solution into the gravity fill port, then top off the fresh water tank completely with clean hose water.
-
Circulate and Soak: Turn on the water pump and open every hot and cold faucet until you smell bleach, let it sit for at least four hours, then drain and flush the entire system with fresh water.
