Q. When we had our house built about eight years ago, the builder installed toilets that flush with 1.6 gallons of water. We are constantly having trouble flushing everything down and have to use a plunger about half the time. What can be done to improve this?
A. As you might know, all new toilets sold in this country since 1992, when a water-conservation law went into effect, use only 1.6 gallons of water or less per flush.
Unfortunately, many of the older, less expensive models of water-saving toilets, have difficulty flushing solid waste. This has improved with newer toilet designs, especially so-called high-performance toilets, but even these sometimes need plunging.
As for older water-savers that flush poorly, there just isn’t much that can be done to improve performance unless there is some mechanical or blocked-drain problem.
Some new water-saving toilets are equipped with a pressure-producing device that improves flushing (it is called the Sloan Flushmate), but this device can’t be retrofitted on existing gravity-flush toilets.
If frequent plunging annoys you enough to make the investment, I suggest having your most-used toilet removed and replaced either with a high-performance model or a pressure-assisted flush model.
