We Recently bought a 2004 Coachmen Concord 235SO. I'm trying to figure out how to make that "Water Works" panel suck the bleach solution into the fresh water holding tank and have had no luck yet. The owners manual doesn't show this panel. It shows a picture of a bigger one with 4 valves and a vague description of the operation. If someone has experience with this, I would appreciate a little tutorial. Thanks.

Have never seen one before, but the winterize inlet and valve probably just suction into the pump and lines, but NOT into the fresh water tank.

Current position of levers is "Tank Fill"Left lever DOWN Right lever LEFTWinterizeLeft lever RIGHTRight lever UPA hose stuck in anti-freeze jug is then connected to Winterize Connection (as shown) and the turn pump on to suck from jugNote:Some Water Works Panels were mis-labeled for WinterizeIf above positions do not work (allow for sucking anti-freeze from jug) then turn Right lever from UP to RIGHTLeft lever and right lever pointing at each other

For those that only have a hose connection to fill the fresh tank, about the best solution is to buy and inexpensive cartridge water filter. Just connect it line with your water hose, and without a cartridge, fill the cannister with your straight bleach. then screw it back together, and fill tank as normal. Depending on your tank size, you may need to fill cannister several times to get required amount of bleach. Then keep the cannister and filter to use whenever you are connected to shore water at a campsite. Some places you need it, others may not, but doesn't hurt anything to leave in it place all the time. Just change the filter cartridge every once in a while.

It appears that the right hand valve is between the pressure side and the tank inlet, i.e. the fill valve. The left hand valve apparently selects where the hose inlet and pump inlet hook up. I would try the left valve in the winterize position and the right valve in the fill position -- i.e. both valves pointed at each other. It may not work.Another method for getting the bleach solution into the tank that many people use is to set the valves to fill, pour the appropriate amount of bleach (undiluted) into the far end of the hose, and then hook it up to the spigot and fill as usual. The bleach will dilute properly when the tank is filled. The short burst of undiluted bleach won't harm the plumbing or hose in any way, though it might not be a great idea to let it sit there for hours or days on end.

I was hoping to get it in my brain just how those valves worked in the plumbing. I was going to put the bleach in this evening and let it set overnite but it got late and didn't have time to experiment with the valves. I'm not sure about the venting of the tank and am a little nervous about pumping into the tank anyway until I know how it's vented. I'm sure it is, I just don't know where it is so I can watch for it to start spitting when the tank is full.

Current position of levers is "Tank Fill"
Left lever DOWN
Right lever LEFT

Winterize
Left lever RIGHT
Right lever UP
A hose stuck in anti-freeze jug is then connected to Winterize Connection (as shown) and the turn pump on to suck from jug

Note:
Some Water Works Panels were mis-labeled for Winterize
If above positions do not work (allow for sucking anti-freeze from jug) then turn Right lever from UP to RIGHT
Left lever and right lever pointing at each other
