Draining fresh water tank

X2 I do the same. Never had a problem with the water.

Congrats!

So that should be the last check mark on your scavenger hunt list :B

Got it! Sometimes knowing there is a solution is the major breakthrough. All your comments made it clear there HAD to be a way to drain the thing.

There is. What looked like a smudge on the plumbing schematic was, in fact, the drain outlet. And the drain hose led to a compartment under the forward seat in the dinette; the electrical stuff is under the aft seat. Makes sense. And the valve didn't look at all like what I was expecting: it's a small version of the "slider" valves which control the flow of waste water from storage tanks to the great outdoors.

The exit route under the coach is a very anonymous short piece of black tubing; I was looking for something that looked more like the drain plug for crankcase oil.

So not only did I find how to drain the fresh-water tank, I found the water pump -- wondered where it was; good to know in case I have to fiddle with (or replace) it.

That's actually the last of the major mysteries. I shudder to think what it would have cost me to take it to a dealer and get these questions answered.

Many, many thanks! In time, I hope to be a source of information, not just a consumer.

There is an old RVnet forum discussing draining the Coachmen FWT. It's for a 31 model so may not apply to the 23 model in which case you may need the 23 manual. It was discussed in 2009. I tried to copy the URL but cannot do so; but you might be able to google it. Also, the 1999 generic Coachmen RV manual is still available online but does not discuss specifically where the drain valve is located. Hopefully someone with the same RV as you can join in here.

That link didn't work for me. Is this what it is supposed to be ?http://www.rv.net/FORUM/index.cfm/fuseaction/thread/tid/22728307/print/true.cfm

My fresh water tank drain is right next to my dump valves (makes sense since it's a low point), maybe you have one near there as well?

You should have a low point drain valve somewhere, quite possibly accessible from inside the coach. We also use the tank water primarily for washing and drink bottled water. But, I sanitize the tank twice a year. It is so easy to do, why take a chance?

Finding the fresh water drain can be like a scavenger hunt......
Can you see all sides of tank? Should be a 'fill' line, a water pump 'suction' line, a 'vent' line and then a 'drain line'. Drain valve could be under RV, inside a compartment, behind a 'panel'. Let the hunt begin :B

Test kit....WHY?
Do you test you house water?

Sanitize
1/4 cup house hold bleach to 10 gallons water
If sanitizing tank might as well sanitize plumbing system by running the bleach treated water thru hot/cold lines
Let sit for several hours then drain/flush/rinse

I sanitize our fresh water tank(s) once....when we first get rid.
After that I don't.
We fill with good treated water source (city water etc.)
We use the water just like we do in S&B House....wash/drink/cook. It's the same water.
We drain fresh water tank if not going to be used with in a month. Then refill with fresh.

As the other poster stated--------look under the tank for a drain. I wouldn't spend money on a test kit. Just add clorox, heavy dose, and let it sit and then rinse the tank a few times. Since you use bottled water for drinking the clorox taste should go away after a while.
