TOTO THP5125#BN – Frequently Asked Questions
1) What exactly is the TOTO THP5125 part, and what does it do on the faucet?
It's the drain lift rod connecting piece, the plunger link that ties the lift rod at the top of the faucet down to the pop-up drain's horizontal pivot rod. Pull the lift rod, this connector transfers the motion and the stopper rises. TOTO lists it as a plunger for single-hole faucets, so it is a replacement part for the pop-up linkage rather than a complete drain assembly.
2) Is the THP5125 for a single-hole TOTO faucet or will it suit a widespread?
TOTO specifies this plunger for single-hole (1H) faucets. If you're working on a widespread or centerset TOTO lavatory faucet, match the lift rod part called out for that specific model instead, because the linkage geometry differs between body styles.
3) Does ordering THP5125#BN get me the whole pop-up drain assembly or just the linkage?
Just the linkage connector. The THP5125 is the drain lift rod connecting part only, so it won't replace a failed stopper, tailpiece, or drain body. If the stopper itself is cracked or the drain body is leaking at the sink, you need the complete pop-up assembly for that faucet model, not this plunger.
4) My TOTO lavatory faucet stopper won't stay up or won't seal. Is this the right part?
If the lift rod moves freely but the stopper no longer follows it, the fault is usually in the connecting linkage, and on a single-hole TOTO faucet that is the THP5125 plunger. If instead the rod and stopper move together but water still creeps past the closed stopper, the seal at the stopper is the problem and this connector won't fix it.
5) What does the #BN suffix on TOTO THP5125#BN mean?
The characters after the hash are TOTO's finish code, which is how TOTO distinguishes finish variants of the same base part number (THP5125). If the exposed linkage on your faucet is visible under the sink only, finish is cosmetic, but when you're matching a maintenance kit across a hotel or multifamily property, order by the full code including the suffix so the parts match what's already installed.
