Dual Flush Toilet Kits

The Award Winning Dual Flush Toilet Kit from One2Flush Products can retrofit most toilets to a dual flush mode, saving you water and money. Well water owners can save too by keeping that pump from running with a full flush all the time, thus saving money on your electric bill. 

And the One2Flush fits more models of toilets than any other dual flush kit on the market.  Other manufactuer models are too tall for one-piece toilets and others don't even bolt to the tank, making them unpassable for some plumbing codes.  The One2Flush bolts solidly to the tank and conforms to all plumbing standards, including the California Green Building code.

Three models to choose from:

• One2Flush for 2" tank openings (most common)
• One2Flush for 3" tank openings
• One2Flush for One-piece toilets 
• Measure before ordering.

Instructions for measuring: 1) Turn off water supply line to toilet. 2) Flush toilet to drain water out of tank. 3) Measure tank opening at flapper. 2-2.5" is most common. the 3" opening will seem pretty obvious. And of course, you should know if you have a one-piece toilet.

NOTE: When ordering for 2-piece toilets (2" or 3") we recommend ordering the kit that includes the flush fill valve if you currently use a ball float to regulate the water intake. Your existing ball float set up may work just fine with a little bending of the rod, but you may be better off replacing the fill valve at the same time as you replace the dual flush mechanism to make sure it will work.
