50 years of experience with flush valve manufacturing and development paid off. All the engineering that has gone into our flush valves has resulted in very little work for you.

Design overcomes low water pressure to deliver strong flushing.
TOTO’s piston valve technology gives our valves a consistent strong flushing action even at low water pressure. This means that the tenant on the 50th floor of a high rise building will experience the same high performance as the tenant on the first floor.

The piston valve advantage.
Every TOTO valve-manual operated as well as sensor-operated takes advantage of our carefully researched and designed piston flush valve. It has a sturdy brass body with just one moving part – a self-cleaning piston – to provide durability and reliability. It also can be ordered with an angle stop with tailpiece, outlet tube with vacuum breaker, wall flange, and fixture spud nut escutcheon.

The heart of the flush valve is a piston which has a self-cleaning, stainless steel screen that filters debris and prevents clogging. It also features a positive seal that provides sure, consistent closing.

In contrast, rubber diaphragm flush valve systems made by many other manufacturers can often warp or clog, making toilets and urinals run continuously or overflow, causing water damage.

Diaphragms also need regular replacement and maintenance, which makes our maintenance-free piston flush valves even more attractive.

	TOTO flush valves do not use rubber diaphragms that may warp, mis-seal or require regular replacement.
	TOTO’s piston technology eliminates pilot hole clogging by using a self-cleaning debris screen.
	TOTO’s flush valves do not have to be reset after water pressure loss.
	TOTO’s maintenance valves reduce those dreaded call-backs.
	Debris in the water supply is handled with ease.
	Easy retrofit - TOTO’s Manual Flush Valve can replace most flush valves without any additional parts.
Minimum/Maximum Operating Pressure	Even a low (20 psi) or high (50 psi) water pressure, our valves perform consistently.

Upgrade your old system.
If you’ve already installed a diaphragm system, you can still save yourself any further hassles. Simply replace it with the advanced TOTO piston flush valve system. TOTO’s manual urinal valve comes in a 1.0 Gpf model and the toilet valve is available in both 1.6 Gpf and 3.5 Gpf models. And whether you upgrade to TOTO or are fortunate enough to buy TOTO in the first place, you won’t have to worry about vandals. Our valve design features a vandal-proof cap.
