Thanks Aaron, I wonder why the manual doesn't even mention reducing the WATER pressure.

On another issue... The manual also states, "DO NOT open termination valves until tanks are 3/4 full.
DO NOT keep black water calve open while parked."

I assumed, if hooked up to a campsite sewer, you just hooked up, opened the Black tank knife valve and go read the newspaper, or do a cross word puzzle.

It also said to keep enough water in the black tank to help dissolve the solid waste. What do you do when you get to the site? Put 10 gallons of water or so into the black tank as part of the setup?

If you leave the black tank valve open you will get a pyramid of petrified poop in your tank that is a PITA to remove. For the stuff in the tank to start to break down and flush down properly you need liquid in the tank and lots of it. Some people will leave their gray valves open when hooked up to sewer. I prefer to let my tanks fill up then dump, keeps "stuff" from building up in them.

I use the Geo-Method for keeping my tanks clean. Typically I will mix up a "batch" in 5 gallons of hot water and dump in the black tank(via the toilet) before we leave on a trip. I will split another bucket full between the gray tanks maybe once or twice a year. I use a big bucket, happens to be a Home Despot Homer bucket, but any similar bucket will work fine. If we are on a full hookup site I will empty and rinse the black tank before we leave, then add water back into the black tank by letting the toilet run for a bit. If we are on non-sewer site I dump and rinse the tanks when we get home. If for some reason we have to use the regular dump station, I will rinse the black tank first chance I get. Always keep some water in the black holding tank unless you are clearing them out for the winter.

Water Pump light?

Turned the water heater bypass valve closed, opened all my faucets and continued to blow out my lines... just to see if any more came out. Can't say that any more did come out. So, with my fresh water tank and lines sanitized, and since our maiden voyage is 10 days away... I filled the fresh water tank to 2/3 full and put everything away. Closed all the calves and opened the bypass valve.

I thought I'd check and see if the hot water tank would heat up under just electricity, so pushed the "ELEC WATER HEATER" button and waited an hour or so. I turned on the water pump, opened the hot water side of the kitchen faucet and Yes, it does in fact work.

I went back to the Control Panel to turn OFF the Water Pump, and alas... it's STILL blue. I opened the faucet again and the pump came on, but only about half as loud. I pushed the pump button back to the normal ON side, and it stayed on, but just a little louder. Looks like the pump was STUCK on.

I unplugged the power from the house, and turned the Coach batteries OFF. The pump light did go OFF as expected. I turned power back to the coach, BOTH ways... and the Water Pump light is still ON, and still works in either position. WTF?

The pyramid of poop makes PERFECT sense. Having NEVER owned ANY type of trailer/motorhome I NEVER would have thought to "pre-fill" the black tank. What's in your 5 gallon "batch".?

Water, cap full of liquid Calgon, cap full of liquid laundry (Tide) detergent and quart of bleach.

Sounds like your water pump switch has crapped out, they are pretty easy to pop out and look at, or just pull the whole panel and look at the back side of it. I would guess that either the switch is bad, loose connection or possibly a crappy crimp job and some wires are bridging where they shouldn't. It could also be on the pump end of the wiring too. So far ours is working the way it should.

Did you turn on the water pump switch on the outside? The inside switch will stay lit in both positions if the outside one is on.

I will DOUBLE check that tomorrow. That possibility crossed my mind, since I was playing with the outside shower during my "blowout" experiment. I'll have my wife help me with it tomorrow.

Aaron, if this isn't the problem, I'll just have them check it out when I bring it back for my 90 day freebe repair, or whatever they call it.

Thanks guys.

Good call! I bet that is it. I seldom use the outside switch, also I am in the habit of turning the pump switch(s) off as soon as I am done with it.

On some other units I have owned we used to wire a momentary switch in the bathroom to use to be able to pressurize the system to flush the toilet, but not leave the pump turned on while traveling. Seen more than one water tank get emptied into a unit when something broke while traveling and the pump kept on pumping. At least on the Concord the pump switch is right by the bathroom so you can turn it on when you go in and off when you come out.

That was EXACTLY the problem. I opened the water station door and the little light was ON for the Pump switch. Thanks so much.

Well I knew about that because I did the same thing. Glad to help.
