Getting all water out of FW tank

The drain for my fresh water tank is on the side of the tank, so 1-2" of water is left after draining. Anybody know of a good way to get the last of the water out?

Go for a drive with the drain valve open. All the sloshing will eventually drain the tank dry.

Another option if you don't want to move the motorhome would be to use the jacks to tilt the rig slightly toward the drain.

If your pump pickup is at very bottom of the tank, running the pump will get enough out as to not worry about it. I always have a half inch or so, which isn't enough to damage tank even if frozen solid.

Thanks for the comments. Not really worried about freezing, just don't like leaving water to sit for 3-4 months.

Bob--you can always do the "bleach disinfecting" procedure on your FW tank after it has been sitting up for a while.

And to get the "old" water out that was left standing, leave the FW drain open and turn on the fill. Let water run through for a few minutes, till the standing water and any sediment has flushed out.

get some wood, put the RV higher on the other side so the drain is lower then the rest.

Leave sit for a while.

The suggestions for flushing with fresh water and adding bleach are right on. Pump the tank down as far as it will go and either flush with fresh water with a little bleach before filling the tank or if you are going to let the coach sit for awhile, add a little water and bleach. This should keep the tank clean and fresh.
Regards,
JimB
