TOTO THP5164 – Frequently Asked Questions

1) Which TOTO faucets does the THP5164 aerator fit?
The THP5164 is TOTO's genuine replacement aerator for the GB and GO series bathroom faucets. If your faucet is from another TOTO line, this is not the matching part. Match the aerator to the faucet series rather than to the look of the old one, since aerator threads and housings differ between families.
2) My TOTO bathroom faucet has weak or spitting flow, do I replace the whole faucet?
Usually no. On GB and GO series lavatory faucets, a clogged or mineral-scaled aerator is the common cause, and the THP5164 is the genuine TOTO replacement for that part. Swapping the aerator is a hand-tool job at the spout outlet and leaves the valve body and finish alone.
3) What flow rate does the TOTO THP5164 aerator deliver?
Rated at 1.2 GPM. That matters if you're replacing a worn aerator on a GB or GO lavatory faucet and need to keep the fixture at its original flow, or if you're standardizing a building's restrooms on a lower flow rate than an older 2.2 GPM aerator delivered.
4) Can I use the THP5164 on a kitchen faucet or a commercial sink?
No. It's specified as a bathroom faucet aerator for TOTO's GB and GO lavatory series. Kitchen and utility faucets use different outlet threads and higher flow rates, so this 1.2 GPM lavatory part is the wrong choice there.
5) Will the THP5164 aerator change the finish look of my faucet spout?
The THP5164 is supplied as a single part option with no separate finish choices, so there is no finish to select when ordering. It's the aerator assembly for GB and GO bathroom faucets, ordered by part number alone.
