Gotta thaw my grey tank!!! Here we go again!

Well, I hit the trail Jan. 26 and headed into the wild wild winter....

I know to be careful with my water usage and have learned to wash things with a thimble full of water and all that, but there comes a time when ya just gotta get rid of some grey water!! But what when it is grey ice??

I am there. When I brush my teeth, water comes up into the sink. Maybe it's plugged, but my bet is the grey tank is full.

I don't dare step into the shower. Even a 3 quart shower is too much. I do have access to a bathroom where I am set up at and I use the potty there instead of mine. Why not? I have a key to the place!

And I wander in there before anyone arrives in the morning, armed with a bar of soap, a towel and facecloth! But you can only do so much.

Aside from that, it's baby wipes to the rescue!! Hahaha! Yeah I've gone through a pile of them. They actually work quite well. Do the pits and other essentials - haha!

But why do I want to smell like a cucumber and green tea? Or smell like a babys butt after cleanup? Better ask Huggies about that one - LOL! Better that than smelling like BO I guess.....

All for the sake of saving water. But that and the sponge bath in the shop biffy keep me going until my grey tank stays thawed enough to use the shower regularly.

Hey we actually warmed up in frozen tundra Alberta yesterday - went above freezing for the first time since I got here Jan 26.

My FIRST thought was my grey tank. Heyyyyyyyy!!!!!!!!!! Maybe it might flow - plus 5C - 38F.... Maybe????

Tried last night - no sale on that one. A little stuff dribbled out.. Wah....

Another warm day today. Maybe????? I get back the the TT after a days work and go back there, get my 5 gallon pail out and stick it under the thingy there and pull the cork. Awwww heck only a dribble again. Heat tape around my dump pipes. Keeps them thawed but after this consistent minus 500 degrees, I know I have a couple tanks of solid ice! Not worried about the black. I used it once for solids and a few liquid deposits. But I open the valve and have a peek - it is liquid right up to the valve. hmmmmm not sure how I managed that one when I only used it a few times. I know the tank is virtually empty. Oh well. grey water is the concern right now.

So it was still above freezing. I'll help it along. Got an old milk crate, got my little 1500W electric heater, the one I use to supplement the furnace, and I lay it on its back to see if it has one of those safety deals to shut it off if knocked over. Nope! Must be made in China! Haha! It runs while laying on its back.

Throw some cardboard in the snow, shove the milk crate under the grey tank, upside down, stick the heater in here at 1500W, and it's right up almost against the grey tank.

Let her rip baby! Lets see if I can get some drainage happening here.

Got my 5 gallon bucket under the drain thingy. An hour of the heater I go out hopefully and pull the cork again. Slight whoosh, got about a pint out.

This could take a while. Gave upon the heat gun.

Maybe I'll let it go all night. I'd really like to wash my dishes in water instead of moistened paper towels and baby wipes!!! Good for salad - tastes like cucumber and I didn't even put any in!!

:B:B:B:B

Ahh winter in the RV at it's finest!

I wouldn't trade this for any fancy hotel!

  • RV living in the winter ain't for sissys or the helpless!

    You the man!!

    Practice on that grey tank..eventually you will have to deal with the black. :B
  • Don, I have spent a bunch of time over the past few days looking for a radiant heater.
    One of the tricks is to find someone at Home Depot, Rona, Lowes, who actually knows what one is.

    I have struck out. I find no stock at any store I have searched. I look every time I ma out getting supplies and can't find one here.

    Maybe it is because it is so balmy here and nobody wants to heat anything!! Don't get it.....
  • Hi Bob,

    Now you understand why I use radiant heaters for thawing? You do have to be darn careful with them.

    Change of state from ice to water requires about 144 btu's per pound. That would take one pound of liquid water from 0 C to 80 c (or from 32 f to 176 f)

    If your grey tank is 30 gallons it weighs about 240 pounds. So to thaw it is going to take about 34500 btus. So your 1500 watt heater is going to need to run for seven hours--assuming 100% of the heat went into the tank (which of course, it doesn't).
  • You have to look at this sideways. Think of that tall bourbon and water you sip under the canopy in the hot summer sun. How long does it take to melt the ice? if you have a good insulated glass it could last hours. Now think of that one big ice cube, how's that going to melt at near freezing (assume it stays over freezing at night but hovers at the zero zone, when will it melt?

    I use my coach year round, but realize the tanks are exposed and will not thaw until it's well over freezing for an extended amount of time. I use a bowl and a bucket in the winter. Bowl in the sink, and the bucket to dump the bowl into. The commode is off limits, period, but a little spill I don't worry about.

    By the way, trying to heat the tank is sort of useless, the extra cold water you melt acts as an insulator for that big ice cube in the middle;
