:confused:Is your toilet on an electric pump of some sort? Not an expert on flushing mechanics, but I'm not sure I've ever seen a toilet that wouldn't flush if the power was out

Never been to a house with a well?:)

I think it's a great Idea. I wouldn't worry about the temperature, you're not introducing enough water to make that big of a difference.

one time when the power was out i used a 5 gallon bucket of dirty fish watter to fill up my toilet to flush it it was left over water i never dumped after doing water changes.

What does the power being out have to do with water?

Ah nevermind, perhaps a well pump... Silly me

Most toilets are made of porcelain, which is a VERY poor insulator. The cost to run that heater would outweigh the part about saving water.

Not heatin the john..
 
I agree with a previous post in here. The amount of water is so small, no need to find a way to heat the water. Even if ice cold, it probably won't affect the total temp of the tank by much at all.
 
This ain't a bad idea! Honestly most DIY plumbing ideas I've seen don't really thrill me, but this one I like. You're saving water and money and doing a little tank maintenance all at once! A check valve on your "green" line is the only change I would make. Also, putting a heater in the toilet tank is a waste of a heater, all that does is heat the water that you're going to flush. If you wanted heat, there are ways to do it, but as stated by someone before, unnecessary do to the small volume per flush. Great idea and good luck!
 
Older toilets can use up to 7 gals per flush. Newer household toilets use from 1.5 to 3 gals depending on the unit. A high efficiency toilet depends on water pressure which you will have almost none. so you will likely be changing about 3 gals per flush.

you will need to modefy the filler valve due to the low water pressure situation. your tank will fill quite slowly so you have to hope everything goes with the first flush, or it will sit for quite a while.

Then there is the issue of the filler valve in the fish tank. if this fails to shut off when the tank fills, then you will have a seriously wet floor. An overflow on the tank is a MUST in my opinion.

My thoughts are it can work but you will need an overflow, a sump and a pump to pressurize the water going to the john.

sketch to follow ...
 
I know a guy that did this very thing, and it didn't work too well.
Never saw the layout/design, but according to him, was a wasted effort.
The way he described it was the fill/overflow method.
Flush the toilet, overflow the same amount to a drain.
Sound like it would work to me, but he said otherwise.
 
Which brings another idea, why have the toilet remove water from the tank? If you had an overflow, couldn't there be a way to just add water to the tank when the toilet is filling, and then the water that goes over the overflow will just be routed to a drain rather than a sump? Just another thought.
