I’m sure everyone is glad for the series of inventors of plumbing and the flush toilet that began circa 31st century BC and ran on until 1907. Somewhere along the way, Sir John Harrington is credited with inventing the first real flush valve toilet while Thomas Crapper invented the first true siphon system for emptying the tank. Always taken for granted, the toilet is considered as one of the major inventions that have greatly benefited mankind. The toilet, commode, john, loo, crapper, or throne; no matter what it’s called, it has earned its place in history as a technological fascination, with almost every home in the world having at least one.
However, a minor drawback to flush toilets is that it normally takes about 2 to 3 gallons of water to flush properly. This may not sound much but, in the long run, the everyday use of a toilet flushed around 10 times daily means the average toilet uses up to 230 gallons of water a day. That rounds out to 1,400 gallons in a week, 5,600 gallons in a month and 67,200 gallons in a year. And that’s just one flush toilet. To save water, this minor drawback can be solved. This can prove useful for areas which have limited water or a scarcity of water.
First, we need to identify which parts of the toilet can be used and adjusted to save water. This obviously involves the whole water closet and the bowl’s siphon. After a toilet is flushed, water fills the water closet until the water float rises far enough to turn the water valve off that fills the tank. A key method to save water in your toilet is to lower the amount of water filling your water closet. This can be achieved by adjusting and lowering the water height in your toilet tank. All you need to do is to lower the water fill valve float assembly by adjusting the float screw outside the assembly.
Lower the float screw so that when the water rises it will automatically shut off the filler valve when the water reaches two inches below the top of the overflow tube. Now, less than 2 gallons of water is needed for every flush. In the long run, the little water saved after every flush will count considerably in lowering the water bill. In some rural areas or large apartment complexes wherein water pressure can’t rise fast enough, a drastic water saving method is to remove the water closet, leaving only the bowl, siphon, and rim assembly. To flush the toilet, a small bucket of water is more than enough to raise the bowl water and flush everything down. In some cases, after urinating, the bowl can be flushed using only a small pail of water.
