How Do I Drain My Fresh Water Tank

[Autin]

I thought I had it figured out but it's still not draining. I have a 2005 Independence 35 ft motorhome. Fresh water tank is under the master bed in the back of the bus. I see 3 valves. I pull up to open the valves but the water will not drain. I opened the filler cap in case of a vacuum. Still nothing. However, if the water hose is hooked up and on, the water will drain from the valves. But not from the tank. Any ideas ?

My journey had the same problem. Previous owner had capped the 1.5 inch drain pipe instead of fixing the leaky cable controlled gate valve. Worth a shot?!

The tanks I've had in the last couple units that I've owned have had their own drain valves. On one tank the drain valve hung below the belly and was turned on by crawling under the camper.

On my current RV, the drain valve is located next to the tank. Have to lift-up the cushions on one of the beds to access the tank and valve.

The method varies with the coach. Sometimes the only way to drain is to pump the water out. On my coach, the tank is drained by opening the low-point drains on hot and cold and then turning the pump on to push the water into the water lines and out the low point drains.

Thanks for the info. I'm just gonna use the pump. Seems easier than trying to figure out valves

What I do besides opening the tank drains. My tank drains seem very slow.
To speed it up, turn on the water pump, then open the kitchen and bathroom faucets. Let the water drain into grey tank and then empty the grey tank.
