BigCountryfan,
Welcome to the Heartland Owners Club and to the Heartland Family!
If you have gotten the bacteria in your system, you should just replace the anode rode completely and flush your entire system with a bleach/water mixture of 1/2 gallon into your holding tank full of fresh filtered water. Then run the water from your fresh water holding tank though every line, faucet, hot water heater (turned off), and drain in your entire system, allowing each one to run at last 2 gallons of water through them (don't forget the outside shower) using the hot water side (remember, hot water heater is off) for a few gallons and the cold water side for a few gallons. Once you have run it through each faucet and hose in your entire system, let it sit for 12 hours before completely draining and flushing your system with filtered fresh water. Flush out your fresh water holding tank 4 times with fresh water and each time allowing a couple of gallons of the fresh water from the tank to cycle through each faucet in your system. Then drain your hot water heater and refill it. After doing that, as long as you are using filtered water, then your system should be clear and clean. If you need to purchase a filtration system the folks at
RV Water Filter Store have great prices and can help you pick out the filter system for your rig that will fulfill your needs.
On a separate note, if you are able to attend (I know this is last minute), we have the Washington State Heartland Owners Club Rally on the 26th - 28th in Monitor (Leavenworth/Wenatchee). We would love to meet you and have you attend the rally. If you have any questions feel free to PM me.
