On my 2005 Beaver monterey ventura IV 36 foot, I'm having trouble draining my fresh water tank. I just bought this RV with no instructions on how to dump the tank. I did locate the drain switch in the main compartment where the water valves are located along with the black and gray drain valves are. However when I push the rocker switch to drain the tank, nothing happens. Can someone tell me what I'm doing wrong? Thanks Dave

David,
The switch should apply 12v or gnd to the Valtera valve that opens to drain the tank. I'd check to see if the switch is OK and if there is 12v present. If OK then check if the signal is getting to the valve. It's located near the tank and there should be a removable panel in one of the storage bays that enables access.

I often find that the rocker switch requires pressing and holding for a bit before the valve under the tank fully opens. Ditto for closing it.
The translucent tank should be alongside the HydroHot in the forwardmost curbside bay.

Welcome to the forum, David.
We have a 2005 Monterey, so our set up is the same. As you know, the fresh water tank is in the bay with the Hydro Hot, just behind the curb-side tire. That is where the drain is, of course, and the water drains straight down out of there. My switch to open and close that valve is electric and can be a little cantankerous at times. When I push it once to open it, I listen for the barely audible little click. And then I run around and look under the coach on the other side, to see if water is coming out. Sometimes I have to go push it again. Make sure your low point drains are closed.
Good luck.

I also echo what Stan just said. Unfortunately water sits in the opening of the needle and seat of the solenoid valve and tends to bind it up. Frequent exercise is the best remedy to keep it working properly. Its almost like us "if you don't use it you loose it! Atrophy sucks, Fred

Check under the AH/HH unit. There is a 2" drain. Ours had a perpetual slow drip. After a number of attempts to fix the drip, I put a 2" plug (the kind w/ a wing nut to tighten it). When I (infrequently) need to drain the tank I just pull the plug and actuate the switch. Also there is a "Low Point" position on the water manifold in the wet bay.

I would add some Vaseline to the valve when open it would help with the open and close operation.

Thanks to all ( Jerry, Jeff, Fred, Stan, Joel, Steve) who answered with the problem of draining my fresh water tank. I will try these suggestions tomorrow. Thank you all very much again. David Stiles BAC member since 11-10-19

As mentioned, check the drain. We had to install a plug (the kind with a wing nut) to stop a persistent small leak. When I need to drain the fresh tank, I remove the 2" plug. There are also low point drains on the bottom of the water manifold. FYI I have a PDF of the owners manual (and many other items in the coach). Send me your email and I'd be glad to send it to you.

Hello everyone, today I tried to dump the fresh water tank with no luck. Steve Huber suggested that I check for 12 volts at the valtera switch. Before I proceed to tear the panel apart so I can get to the back side of the switch so I can check for voltage, I just wanted to check with everyone to make sure this is the right procedure for removing the switch. Thanks again for everyone's help. David Stiles

David,
Before you tear into it, try spraying the switch with some contact cleaner and then operating it a few times. If you are going to check voltage & gnd it might be easier to access the dump valve and check for voltage/gnd there when the switch is pushed. As Stan noted, there is a removable panel on bay adjacent to the fresh tank. I use a pin or voltage probe (with light led and sharp point) to pierce the wire insulation to check for voltage. The diagram for the Auto Drain shows a 0.5 amp slow blow fuse in the circuit between the battery and switch, but I don't know if where Monaco put it. As others have noted, it is possible that the Valterra valve has failed so accessing it now could save you work later. I'll email you the auto Drain info on the valve assy.
