Is it worth it to switch to a flushstar toilet? Not according to my math. Please correct me if I'm wrong.

I'm paying $650-$720 every two months for water/sewer/garbage for my 6-unit 1978 rental property. I

I checked w/ my city and they charge $1.95 per CCF for anything over >15

According to my research:

ccf= 100 cubic feet which = 748 gallon

If the above is correct. The articles at http://www.savingwater.org/ said that the average home uses 19 gallons of water/day. If they used a flushstar toilets, the average would be 8 gallons/day. I don't think this is accurate. I google search it and found that the average person flushes the toilet 5 times/day.

A household of 3 would flush 15 times a day on average.

I am assuming my 1978 toilets are 5 gallon toilets. I'm going to subtract 1.6 gallons from 5 gallons since that's what the low flow toilets would be using. That means I'm wasting 3.4 gallons per toilet.

3.4 gallons multiplied by 15 flushes is a waste of 51 gallons per unit. I have 6 units so that is a total waste of 306 gallons a day, which is 9180 gallons/month. Year would be 110160 per year.

110160 gallons divided by 748 (1 ccf) is 147.27 ccfs.

147.27 ccfs times $1.95 is $287.18 per year that I would save.

Toilet will cost me $230 each X 6 = $1500 w/ tax.

$1500 divided by $371.64 is 5.22 years to break even

here's my water rates:

Now the question is, is it worth it? Probably in the long run if I decide to keep the property for longer than for years I would be netting $371 per year.
