Thanks for the heads up with water in the toilet! Yeah - try pulling up - that's how mine work. Also - using the low point drains will not drain your fresh water tank - you have to drain that separately - usually with a turn valve on the bottom of the tank.

Well i'm not sure about that. At least on my TT. I opened 4 low point drains last week. Two of which are knobs that your turn under the trailer by the tanks. The other two are in the drivers side rear storage under the water heater. Those are the pull-up variety. When I pulled them there seemed to be a little pressure behind them. Later when I unscrewed the plug on my water heater, nothing came out. Not a drop.
All this was done while trailer was sitting level. After I hooked up to put back in storage, I was amazed at how much more water came out.
I stand by what I stated...
Well than, any idea as to how my hot water tank was empty when I unscrewed the plug?

In hindsight, I believe I should have opened the facet tap to release any vaccum pressure? Or do you pull up on the valve to get it to drain?
Do you normally drain all your water if storing it for a week? Do you leave water in the toilet ontop of the flapper too?
Thanks for your insight!
You can't drain the water in the fresh water tank via the LP drains since the water pump is in line with the fresh water tank. The LP drains will only drain the water from the pipes after the water tank and the HW tank and opening at least one faucet on the hot and cold will help especially for the HW tank.

If I open the low point drains and lift the pressure relief valve on the HWH, the HWH drains. When the water quits running I let the pressure relief lever back down. Can't close the door on the HWH with the lever up.
