Ok, let me ask the question again. What is the proper procedure to drain the fresh water tank. I thought I knew how, but it wont drain. What could be the possible cause? Bob

You have to open the fresh water tank drain cock which on most of the coaches is located next to the black/grey tank drain where it comes through the underbelly. I know on the Big Countries the fresh drain is just "T'd" into the line that goes from the tank to the pump. Sometimes this is not the lowest point on the tank, thus leaving residual water in the tank. If you can get the trailer leaning toward the DS and slightly lower in the front (unless you have/had your tank shimmed) you will maximize the amount of water drained.

Another option is to run the water pump and let it drain through the grey tanks. Goes a bit faster that way.

Rubiconag, thanks for the help. I wish the owners manual was a little better. Now answer this if you can. Just what do the low point drains, drain? Then the fresh water drain is the one on the left side middle of the coach. White plastic hose. Ok, I will try it again. Thanks Bob:D

The low point drains only drain the water lines. The gravity tank drain is on the off door side coming through the belly. It has a valve on it. I have difficulties draining my tank also. It tends to develop a sagging bottom so the nose of the trailer has to been lowered significantly to get it totally drained.

Why don't you unscrew the drain plug for the hot water heater, then pop the pressure releaf valve. With the pump on the fresh water tank drains in no time. We're talking serious flow here, not a trickle.

Thanks Vango, you know my bottom saggs too. In the morning I will give it a whirl. I just want to get all the old water out. Ray, the other Ray, you mean run a fauset and hook up the drain hose? Bob

I wish i understood what u guys are talking about. The dealer filled up the fresh water tank one third a month ago and I just read in my manual that it needs to be dumped every month and replaced. Guess i will wait till the socal rally next month to let the pros show me where the drain is and the best way to drain then refill.

If you guys are real serious about using the fresh water tank. Roll up you sleeves and lets get to work. When the tank is empty pull the bottom off. (its really not that difficult and you just have to take off whats under the tank) and "shim" up the door side of the tank opposite the pump pickup. You can raise that side of the tank approximately 2 inches. I used a 2X4 and slide it a foot or so in from the end. You will be able to figure it out when you are under there. Gravity will now take that water and send it to the pump intake. NOW when you are camped and even some what un-level the water will always go to the pump. NOW you can put as little as 5 gallons in the tank and it will let your pump do its job. NOW when you drain you tank most of it will come out. Simplest and best fix since TimK's TENT IN THE VENT.

Not sure about the '09 but should be on the off door side. The one with a valve is the drain and another for using the pump to power drain....Ken

is the drain a certain color? and the pump to power the drain, helps drain quicker or is it used while adding water or for what purpose?

If you have water in the tank..open the valve you see on the off door side, underneath, attached to a short hose. The UDC is were the valves are that enables you to use the water pump to power drain , that hose is also underneath and almost or is drectly underneath the UDC....Ken

Howdy, listen to Retired, he knows of what he speaks.
Unfortunately those big flat tanks need a little TLC and adjustment to drain properly.

Crash, you really need to keep that tank clean, use a little bleach and keep it drained when in storage. Make up a list and some body at the rally will go over every thing you have questions about.......................

Roger I thought all the '09s had 2 smaller fresh water tanks and the water glitches and drain stuff was corrected. I guess I'm thinking with the smaller tanks if the trailer is level should be a none issue,filling or draining.:confused:...Ken

Ok guys, the mystery is solved. I finally found the drain hose. It was up inside the under belly. The hole was there but it was still stuffed up inside. I pulled it out and NOW it is draining as we speak. Thanks for all the help. :) Bob :D:D:eek:

Chris at Heartland factory told me today my drain hoses are red and blue and nearby and under the front door. Thats the diff according to him on the 2009 bh.

Just watered up my Sundance yesterday for the first trip and seems I had 1/3 of a tank before I could get water to come out of the drain . Sure makes it tough to flush out the tank. You would think with alittle common sense they would know the drain has to be at the lowest point.

The HOT & COLD water line LOW POINT DRAINS are RED & BLUE, not the FRESH WATER TANK DRAIN. - At least they are this way on the 2009 Cyclone.

Do you have a beam across the bottom of the water tank going from frame to frame? Are you blocked up opposite the drain side a few inches when draining? Those big flat tanks bulge down in the middle with water in 'em and don't have a China mans chance of draining all the water unless you do the above. Believe me I have fought this for a year and a half. That is why I "shimmed" up the off drain side and installed a channel iron under the tank. If you are a serious boon docker get to work on it. If you hang around RV resorts, seems most folks do, I wouldn't worry about. O and by the way, 90% of the RVs with big tanks are probably plagued with this problem. I am guessing that the two tank setup with a cross over pipe is going to be worse.

Bill, I only have the 1 tank. I did get it to drain after I found the drain hose still stuffed inside the under belly. Moniter still reads 1/3 in tank. When I can im going to shim the tank. If I had my way there would be no dry camping. DW insisted on this time. Bob:D:D:eek:

Bob listen to Patty! Nothing better than getting out and no one around for miles.
Back to the tank. When I had the bottom off I noticed that the pump pick up is 1/2 to 1 inch above the bottom of the tank. So shimming is almost a must to get the full capacity. Also noticed the 1/3 tank sensor is about in the same height from the bottom. So when you get to 1/3 because of the distance to the next senor you are going to have anywhere from approx. 20 gallons to about out. Now when filling the tank take into account that it take 12 gallons to fill the water heater and a few more to fill the water lines. So its going to take almost 20 gallons of water just to set things in motion. Confused!? :confused: I am!

An added thought: Dont know if Heartland would read this, but. If they were to weld the mounts for the fresh tank so it would angle down towards the pump and drain side it would take no more time or money. And it would eliminate 95% of these water tank posts. :D

Bill, Haven't had the under belly off yet . This will be the first time we've had our trailer out since we bought it last Nov. Our old 5ver had the water tank sitting on plywood so I could get every drop out. I spend quite a bit of time dry camping while hunting so I will have to do something. Thanks for the tips and like you said why doesn't Heartland slant the tanks when they put them in.

I'll be taking off the bottom covers as well so I can get a visual. On our 08 3100RL we have the same problems everybody is talking about. I'm going to heed Retired's advise and get serious about fixing the issue about getting all the water out. We dry camp 95% of the time, so it's an issue. It's hard to go ahead an take a shower when the meter says 1/3, not knowing if there'll be water there to flush the potty!
