New Kodiac 283BHSL Owner

Hi everyone,
Glad I found this forum as I am new to camping with a travel trailer.
I purchased a used 2020 Dutchman Kodiak 283BHSL last week and want to flush the cold and hot water tanks before using them.

There is a hot and cold water drain valve on the door side, near the rear of the trailer. I filled the hot water tank, and added approx. 10 galls of water using the potable water inlet. I opened the faucets in the trailer (pump off) then open the 2 drain valves expecting the hot and cold tanks to empty. I only collected about ¼ to ½ a gallon of water from each. I expected the tanks to drain all if not most of the water out.

Any tips on what I am doing wrong to flush the 2 tanks would be a great help.

Ok, I don’t know your specific rig, but I’m betting that you are misinterpreting what your tank & drains are.

The drains you see are most probably your hot & cold water low-point drains, which are used when winterizing your rig to ensure no water remains in the water supply lines. Ergo, you will not get much water drainage from those lines, especially if no water pressure is present.

Your hot water tank drain is normally located right on the water heater itself, accessed from behind a panel on the side of the rig.

You other tanks are as follows:
- fresh water tank
- black sewage water tank
- grey sewage water tank

All of these tank drains should be labeled somewhere on the rig… either in the wet bay (if your rig has one), or by cable-pull handles on the underside of the rig.

The fresh water tank (or cold water, as you think of it) will probably drain direct to the ground… while the 2 sewer tanks (black & grey) will drain via your sewer outlet.

As you say you are new to camping, may I respectfully suggest you read at least one of these books, and research some new camper videos on YouTube. They will explain a lot:

Thanks for the info, I appreciate the help and no offense taken.
Took another look underneath the TT and of course found the fresh water drain right away.
