TOTO THU398#01-A – Frequently Asked Questions
1) Is the TOTO THU398#01-A trip lever a left-hand mount?
Yes, THU398#01-A is the left-hand side trip lever, meaning it mounts on the left side of the tank as you face the toilet. If the flush handle on your tank sits on the right, this is the wrong part for that tank.
2) How do I make sure I order the right TOTO trip lever for my toilet?
Match three things: the side (this one is left-hand), the color (Cotton White), and the TOTO part number your tank calls for. TOTO trip levers are model-specific, so the safest check is the THU number listed in your toilet's parts breakdown. If it reads THU398#01-A, this is it.
3) What exactly comes with the TOTO THU398#01-A, just the handle or the mounting hardware too?
THU398#01-A is the trip lever assembly with its mounting block hardware, the handle and the arm that lifts the flush valve. It does not include a flush valve, flapper, or fill valve, so if the tank isn't holding or refilling properly, the trip lever isn't the part that fixes it.
4) Will the THU398 fit a tank with the handle hole on the front instead of the side?
No. This is a side-mount trip lever, left-hand side. A front-mount tank has the hole through the face of the tank and needs a front-mount lever instead. Check which face of your tank the existing handle passes through before ordering.
5) Is a toilet trip lever something a maintenance tech can swap without a plumber?
Yes. Shut the supply, flush the tank down, unhook the chain or lift rod from the old lever, back off the retaining nut inside the tank (TOTO levers use a reverse-thread nut, so it loosens clockwise), pull the old lever, and fit the THU398#01-A in the same hole. It's a common in-house repair for property managers and MRO crews, no supply line work involved.
