TOTO THU658-A – Frequently Asked Questions
1) Is the TOTO THU658-A trip lever a right hand or left hand handle?
It's the right hand version. TOTO trip levers are handed by which side of the tank the lever mounts on, so a tank with the hole on the left side of the front face needs the left hand part instead, not this one. If you're replacing a broken lever, match the side the old one came off.
2) What thread does the TOTO THU658-A trip lever use to mount?
M12 threaded stud. That's the mounting stud on the handle body, and it's what the retaining nut inside the tank threads onto. A lever with a different stud thread will not tighten down in the same hole.
3) Is the TOTO THU658-A a genuine TOTO replacement part or an aftermarket lever?
Genuine TOTO, ordered as part number THU658-A. It's a factory replacement part rather than a universal aftermarket handle, which matters on TOTO tanks because the lever arm geometry and stud thread are specific to the tank it was built for.
4) Can I fix a running or loose-handle TOTO toilet by replacing just the trip lever?
If the problem is the handle itself, yes, the THU658-A swaps out on its own. A loose, cracked, or snapped lever is a lever job. But a toilet that keeps running after the handle returns to rest is usually the flush valve seal or the fill valve, and a new lever won't change that. Diagnose which one you have before ordering, because these are separate parts.
5) For a multi-family or hotel with a lot of TOTO toilets, is the THU658-A a single standard handle or do I need to check each unit?
Check each unit. Handing is the first thing to confirm, since the THU658-A is the right hand lever, and TOTO uses different trip lever part numbers across its tank models. For a fleet, the practical approach is to pull the tank lid on a sample of each toilet model you own and record which lever part it takes, then stock accordingly rather than assuming one handle covers the building.
