Hi Mtmauler,
If this was purchased new, the blue pouch with all your manuals may be tucked away inside a cabinet or drawer somewhere. If not, the dealer may have taken it out to protect it and forgotten to give it to you. So you might contact the dealer to ask about it.
You can download the current trailer manual from the HeartlandRVs.com website.
Here's the link.
In addition, we have an extensive collection of manufacturer manuals for appliances and subsystems. You can reach it from the TOOLS button at top of page. Look for HOM - Heartland Owner Manuals. You can also get there from
this link.
Within the manuals section of the forum, we also have a number of owner-written user guides, including one on the water systems. Again, you can reach it from the TOOLS menu. Look for HUG - Heartland User Guides.
Here's a direct link.
The fresh tank should drain nicely by opening the drain valve near the axles - usually on a while hose.
The red and blue lines further forward could be low point drains used in winterizing - not all models have low point drains and I'm not sure about the Torque models. It also could be for fresh tank overflow if you have the 4-Way Anderson Valve at the water inlet. Another possibility is the washing machine overflow drain line, if you have washer prep.
Another Torque owner might be able to give you more specific info on the red and blue lines.
