Todd provides his experiences with installing and using an efficient dual flush toilet.
We were similarly impressed with the performance of our dual flush toilets -- very good flushing on the "low" 1 gallon flush.
My toilet! This spring my 40 year old septic drain field failed. We already had plans for renovating our bathroom and had purchased and ordered much of the materials. After much research I had ordered an H2Option toilet manufactured by American Standard. They also sell this toilet as the Eljer Somerville. The Eljer is only available with a round bowl and non insulated tank. American standard claims to have completely redesigned this toilet from the ground up as a dual flush toilet. WOW!!!! I can not believe the efficiency of this thing. Try as we might we have not been able to get it to clog or not fully flush even with the .9 gallon flush. I am going to actually resize the drain pipe from 4" to 3" as I feel that flushing solids with the .9 gal. flush needs a smaller pipe to keep things moving. The toilet I removed was a 5 gallon flush American Standard that was about 40 years old. My parents also have an A.S. that is about 30 years old so I feel that they are a quality company. They are an American company though this model appears to be manufactured in Mexico. The nice thing about it is that American Standard toilets are available through almost any plumbing supply house and even many big box stores like Home Depot. You can even order it through walmart.com, though I personally do not like that option. I purchased mine through a small town hardware store. Even though I paid a bit more than purchasing directly from the plumbing supply house, I helped to support a valuable resource when I need that one part on Saturday at 5pm. A midwest hardware/building chain called Menards, regularly puts the Eljer model on sale for $175, so it is even a relatively inexpensive option considering its savings potential. I had to have the septic tank pumped in February and again about 6 weeks later in April. I installed the new toilet in late May. Its now the end of June, and due to weeks of rain I am still waiting to get the drain field installed but I have not had to pump the tank again. I have 4 kids including 12 and 14 year old boys. They use a 5 minute timer in the shower though as they know we need to be very conservation minded at the moment. We also have a front loading washer and efficient dish washer. Thanks again for the great site! Todd

I might adjust my "full" flush down to about 1.3 gallons and see what happens. The toilet pegs the scores on the MaPP testing that I see you already have a link to on your water page. I personally think it flushes better than the Caroma toilets that I have used, and it stays cleaner as it has a quite large "water spot," or as the kids would say... target. It seems quite silly to me to get so excited about a toilet, but this one really is a homerun. It flushes better than my old 5 gallon model just using the .9 gallon setting. Just imagine if everyone installed these. Composting toilets are great but it is very difficult to get approval for not having a septic system in my area. Also I am lazy, that is why I am installing solar panels instead of a wood boiler! Composting for 6 people is time and space consuming.
