2017 Grand Design Solitude water lines help?

[Dickson]

Wondering how one goes about cleaning my water lines? Sadly, those I bought it from are no help. TIA

The inside or outside of the water lines? What needs to be cleaned? How did they get to where they need to be cleaned? How long have they been dirty? What made them dirty?

Sanitize plumbing system
1/4 cup regular household bleach per 15 gallon of water capacity

Fill fresh water tank with appropriate amount based on tank capacity
Bypass the water heater
Turn pump on and flush bleach water thru hot/cold sides of each sink faucet, each shower faucet, toilet, washer hot/cold (if equipped) and Hot/Cold Low point drains
Let sit overnight
Then drain fresh water tank...flush/rinse/drain until no bleach smell then turn pump on and flush each end point to remove bleach solution from lines
