TOTO Faucet Installation
TOTO bathroom and kitchen faucets use standard US plumbing connections -- 3/8" compression supply connections, standard hole sizes (1-3/8" single-hole, 4" centerset, 8" widespread). TOTO provides English installation instructions and a US support line (1-800-350-8686) through TOTO USA. One TOTO-specific note: TOTO's aerators use a proprietary Soft Flow aerator design that produces a softer spray pattern than standard aerated flow. The Soft Flow aerator is non-removable on some TOTO models -- if flow restriction develops from sediment, the faucet must be returned to TOTO service rather than cleared by the homeowner.
