PHOENIX, Nov. 21, 2016 /PRNewswire/ -- Parker & Sons understands that most individuals go through their entire lives without giving much consideration to toilets until they are forced. When that situation arises, they are often ill equipped to handle the issues confronting them. If individuals are shopping for a new toilet, or are facing toilet problems, they could probably use a hand. To that end, Parker & Sons is prepared to talk about toilets.

The best toilets are capable of saving water while delivering a worry-free, or even enjoyable bathroom experience. Finding such a toilet is not always a simple thing. Parker & Sons further notes that toilets that deliver a higher water volume are not necessarily better at flushing. In terms of performing an optimal flush, design is what truly matters. Toilets are regulated by the United States Department of Energy. In 1995, new standards were set that dictated that toilets could only use 1.6 gallons of water per flush. Toilet flushing accounts for nearly 30 percent of all residential water use in the United States. Parker & Sons reports that some states set even more stringent flushing standards. California for example, has set a limit of 1.28 gallons per flush. There are two standard types of home toilets, gravity-feed and pressure-assisted. In gravity-feed models, flushed water is delivered from a storage tank to the toilet bowl when a watertight seal is lifted by depressing an external flusher. Pressure-assisted toilets are more expensive and thus are seen less frequently than gravity-feed toilets. They deliver flushes with more force. They often stay cleaner than their gravity-feed cousins, although their flushes are very noisy.
