i have been doing this and it works great - except i didn't know about adding sand until now. no wonder the bottle would tip once in a while! i guess i could use small rocks or marbles to weigh down the bottle as well as sand?

does this work for septic field users as well? we have well water and a septic field, so i'm wondering if it won't clog the lines from less pressure. we just recently purchased an older home with its original (or at least the inexspensive and water hungry) toilets installed. i would definitely like to save more water with this easy technique, but don't want to mess up my system.

we've been doing this for a few months now and we're waiting for our water bill to come to see how much we saved.

Will the 'force of flush' still be the same? I have a problem with my toilet clogging and not fulling draining.
-Even if it does affect the force I will try to implement this method at my cottage where water needs to be maximized most. thanks!

how do i find out how much water my tank holds? I know we don't have a low flow and the last time we replaced the toilet was like i think 10 years ago! :\

I always use this method for the apartments ive been living in. Dont use a brick, they eventually fall apart into little bits and clog the drain

We just installed a low-flush toilet from Lowes (a bestseller they said, for about $150 including all parts) which is so much lower flushing than my last low-flush toilet I wouldn't dare add anything to the tank. It's only been a month, but so far, I really recommend it--of course I forget the brand.

My apartment came with a bottle of water in the tank. Recently the toilet was not flushing properly because the bottle was leaning on the "flapper"- the end of the white "L" shaped thing attached to the flush-handle. the plumber put new mechanical parts in so the toilet uses less water but I don't have to put a bottle in it.

I've been doing this for the past five years! All the water adds up!
