best way to flush water systen on 03 cardinal

just bought a 03 cardinal, I do see anti-freeze in the lines. can I hook up to my house lines and run water through the system or is that to much water pressure? Of course there was no manuals - it was a repo. So far everything looks good and it seem to have been well care for.

On my old camper it only had holding tank and pumps and did not hook up to city water like this one.

Yes, you can hook up to any outside faucet however, you do need a pressure reducer/regulator. Available at any RV place & most Wal~Marts $8 to $10. Hooking up to city water works well - a good way to get air out of the lines. When filling the hot water heater hold the pop off valve open to let the air escape. When water starts running out release pop off valve.

In addition to other post, you will also want to flush not only the lines but the fresh water holding tank. Just like you did with your other camper.

You also might want to add water to your fresh water take and let the pump run to flush out the lines that the pump is connected to.
