Fresh water tank won't drain completely

We have a 2017 Siesta 24SV.

The freshwater tank never empties completely. There is more than an inch of water left in the bottom of the tank. When trying to winterize, I looked at the tank better and realized the drain is on the side of the tank.

What is the best way to get this extra water out of the tank? With temps dropping into the teens, we have left a heat strip in that compartment temporarily. Any suggestions appreciated.

You could run the "opposite" wheels up on blocks so that the RV is tilted and the tank would drain.

You can never get it all out down low as it is it will freeze and expand up doing no damage to the tank just make sure the line is drained

yup a little water in the tank won't damage anything as long as it has a place to expand into when it freezes.

Thanks for the replies. It's reassuring to know there won't be any serious issues in having some water in there! All the lines are drained, so it should be OK.

I wet winterized mine today. Very simple and inexpensive. Basically drain the tank, pour in potable antifreeze, and run it through the water pump starting at the farthest faucets until antifreeze comes out. Leaves antifreeze in the fresh tank, puts antifreeze in the lines and the holding tanks. I use a 50/50 mix good for down to -50℉, but I live in Alabama, and if it gets that cold here, we are all in trouble.

Oh, yea, and let some run out of the drain to flush it and get some antifreeze through that line as well.

Personally I don't put antifreeze into the fresh water tank... It is just fine drained as low as it can... It's drain line is empty.
I add antifreeze (when using than method vs. compressed air) though a provided tap between tank and water pump.

Getting the antifreeze OUT of a fresh water tank that retains an inch of liquid is more of a pain than I choose to deal with.

Nearly all the coaches I have observed have the same issue. It is true the water in the bottom will not hurt the tank. However, the line from the tank to the on board pump also has water in it and can freeze the pump and line. An easy way to drain the tank is to open the discharge valve and drive it. It has worked for me every time. The movement of the vehicle sloshes the water enough to get it out. Or you could raise the opposite side of the coach with blocks or levelers...

I do add antifreeze to the tank and use pump to get the lines protected. A lot of people do not like the approach due to the need to flush the tank in spring....
