Toto TRIP LEVER - LEFT HAND SIDE - THU808#PN-A

Left hand side. The THU808 is the left mount version, so it goes in a TOTO tank with the flush hole on the left face, looking at the tank from the front. Trip levers are not reversible, so a right side tank needs the right hand part instead. Check which side the hole is on before ordering, because the lever arm is bent to reach the flush valve from one side only.

It is the flush handle assembly on a TOTO toilet tank, the lever you push plus the arm inside the tank that lifts the flush valve chain or strap. It is a repair part, not a complete toilet or a flush valve. If the handle is loose, cracked, snapped at the arm, or the plastic nut behind it has failed, this is the piece that swaps out. The full manufacturer part number to order is THU808#PN-A.

The trip lever ships as the handle and arm with its mounting nut, which is everything needed to put the handle back on the tank. What it does not include is the flapper, the chain or strap, or the flush valve itself. If the old lever broke because the chain was binding, plan on a flapper at the same time, since a handle alone will not fix a slow or running flush. No tools beyond a hand tighten of the retaining nut are required, and the nut on a TOTO trip lever turns the opposite way to a normal thread, so back it off clockwise from inside the tank.

For a property manager standardizing on TOTO, the THU808 is worth knowing by number because one broken handle is the most common tank call you get. It is the left mount version, so before you stock a shelf of them, walk a few tanks and confirm the flush hole is on the left across the models you run. A mixed fleet will need both hands. The finish is a single option on this part, coded PN-A in the part number, so ordering by the full THU808#PN-A string keeps the trim consistent from one unit to the next.
