I do believe in color coding also. When my water hose starts to age, I mark both ends with red tape and it becomes the black tank flush and stinky slinky rinse hose. When replacing my water hose I make sure it has good solid brass fittings. That makes it much easier to hook up with no leaks.
Another thing I started doing a few years back is using a pump spray bottle filled with bleach solution on the camp spigot before hooking up my hose. I have seen dogs lick tall spigots and the short ones get no respect at all.:)
When you bought it the indicator showed that the black water tank was half full?
The previous owner most likely let the black tank sit and go dry. The solid waste (aka Poop) is now like concrete. It will take some time, water, and soap to clear it out. Liquid Tide soap is a good wetting agent.
Never use any drain cleaners, they will damage plastic tanks, rubber seals...$$$.
Dump...Fill with water and soap, let sit, drive with a few good STOPS, dump.
Then start over. It may take a few times. (A CLEAR hose fitting will let you see what progress you are making.):p
(By the way, the chemicals sold at RV stores and walmart are not any better than just soap....Just $$$ down the drain :)
Been there done that....Guess what problems my kids bring to DD to fix?
Check to see if your slide has two motors. If it does, the FWD one may not be running. I would check that first. Read your manual for alt extend info.
The Winnebago website has manuals and parts drawings you can download...Will show where motors and locks are located.)
Be glad it is broke in the closed mode. (you can drive it to the shop if needed)
Let us Know what you find, please.
Just had my MH in the shop. Had the fresh water dump valve and flex line replaced. To do this they had to remove the water control panel (valves, inlet, and filter Assy.) to run the new flex line.
The Good News...The valve can now be opened and closed with ease.
The Bad News...The "O" ring from the filter was lost.
Try to replace on the weekend...NO WAY!:M
Dealer and shop closed.
Camping World will order (Package of 10 @ $16 +shipping?) So no help there.
I packed the filter "can" around from RV stores, Home Depot, Wal-Mart, etc.,etc. Trying to match the "O" ring groove in the "can". Ended up with a Culligan part. From Farm Co-Op. Just a little bigger around, but I was able to FINESSE (as in craftiness & maneuvering) it in place. Then I was able to flush out the red stuff and refill with bleach added to the water, let stand then flush and refill. Then I went on to check out the water heater, pump etc. Ended up working later than I had wished, but us old guys can do that if we want.
Today, Monday, went back to the Winnebago Dealer's shop. I was armed with the part numbers from the build parts list. They ran the number and that was what they had also. They had that part, sound good. I hope so. Free is a fair price considering. Will install with new 10" filter cartridge in the morning.
SHURflow brand...Winnebago part numbers
Filter Assy. 155482-01-01A
"O" Ring 155482-01-700
It seems that many people have a problem getting this "O" ring. Used on many Winnebago MH.
Called SHURflow and they said that Camping World was the ONLY source.
As I said, CW does not stock but will order. They do sell complete filters, DUMB!:S
SEE YOU ALL>>>>DOWN THE ROAD (yes I'm yelling):D
Try ebay..."wiper arm cover"
I found many pages of 50 each, wiper parts.
Your photo looks like a Porsche 911--928 cover. You could use duct tape :)
But that will give you a place to start.
The valves are under the entertainment center. Open door, remove side-wall and you are at the back of the water heater. Upper and lower check valves.
Been there done that. (We are on the road so can't send photos)
