TOTO THP5298#PN – Frequently Asked Questions
1) What is the TOTO THP5298 part, and what does it do?
THP5298 is a TOTO faucet flow regulator rated at 2.5 GPM. It sits in the faucet's water path and caps flow at 2.5 gallons per minute, so it's the part you order when a faucet is running at the wrong rate or the original regulator has clogged with scale and needs replacing.
2) What exact TOTO part number should I order for the 2.5 GPM polished nickel ball joint regulator?
Order TOTO THP5298#PN. The #PN suffix is the finish code on TOTO's part numbering, and THP5298#PN is the only configuration this regulator is sold in, so there is no separate size or thread option to specify.
3) Can I use the THP5298 regulator to reduce flow below 2.5 GPM for a low-flow retrofit?
No. The THP5298 is a fixed 2.5 GPM regulator, not an adjustable one. If your spec calls for 1.5 GPM or 1.2 GPM at the lavatory, you need the TOTO regulator or aerator rated at that flow instead, not this one.
4) Is the TOTO THP5298 a complete faucet or just a replacement component?
It is a replacement component only, a 2.5 GPM flow regulator for a TOTO faucet. No spout, cartridge, handle, or mounting hardware comes with it, so if you are replacing a whole faucet or rebuilding a valve you need those parts ordered separately.
5) I manage a building with TOTO lavatory faucets, how do I know this regulator matches mine?
Match it by TOTO part number, not by look. THP5298 is a TOTO-specific service part, so the safe check is to pull the regulator from the faucet you are servicing and confirm your faucet's parts breakdown calls out THP5298. Generic aerators and regulators from other brands are not interchangeable with TOTO's.
