Flushing efficiency. It’s a challenge for all toilet manufacturers. Since Congress mandated a 1.6 gallons per flush (gfp) maximum almost two decades ago, toilet companies have been trying to do more with less. After all, what’s the point of a toilet that uses only .8 gpf if you have to flush it three times to get the job done?

Enter the world of toilet accessories. No, we’re not talking fancy handles or chromed-out parts. We’re talking easy-to-install valves that take an ordinary toilet and make it, well, extraordinary.

Or at least more efficient.

The FlushAll is the newcomer on the block, a $20 “high performance valve” that provides 40% more flushing power with less water. According to the company, a home can save 2,500 gallons of water per year, per toilet. It all adds up, folks.

Installation takes about 30 minutes and there’s a helpful installation video for those lacking plumbing instinct to follow.
