TOTO TLK01401U – Frequently Asked Questions

1) What exactly comes with the TOTO TLK01401U sub-tank, and does it include soap or a pump?
The TLK01401U ships as the 20 liter (5.3 gallon) sub-tank only. No soap and no battery are included, and it contains no battery of its own. You'll need TOTO Biodegradable Green Seal soap (#TSFB) to fill it, and the Auto Sensor Soap Dispenser it feeds.
2) Will the TOTO 20 liter sub-tank fit in the cabinet under my lavatory counter?
Plan the cabinet space around 16.312 x 14.188 x 7.875 inches. It's a plastic tank weighing 10.65 lb empty, so you also want a shelf or base that can carry the filled weight of roughly 5.3 gallons of soap. Measure the clear opening of the cabinet door too, since the tank has to go in as one piece.
3) Which TOTO soap dispenser does the TLK01401U sub-tank work with?
It's built for the TOTO Auto Sensor Soap Dispenser, feeding it from a remote reservoir instead of the small onboard bottle. TOTO states the tank is designed to hold TOTO Green Seal soap and is compatible with the Auto Sensor Soap Dispenser.
4) Can I put any bulk hand soap in the TOTO sub-tank, or does it have to be TOTO soap?
Use TOTO Biodegradable Green Seal soap, part #TSFB. The tank is designed for that soap, and TOTO calls it required for proper function of the Auto Soap Dispenser. Thicker or foaming soaps from other suppliers aren't what the system was built around, so substituting is how these dispensers end up clogging.
5) Is a 20 liter soap sub-tank worth it for a high traffic restroom, or should I just refill the dispenser bottle?
For an airport, stadium, school or hospital restroom, the 5.3 gallon reservoir is the reason to do it: it cuts how often a custodian has to open the cabinet and top off the dispenser. For a low-use office or single-tenant washroom, the dispenser's own supply is usually enough and the sub-tank is extra plumbing and cabinet space you don't need.
6) What is the TOTO part number for the 20 liter auto soap dispenser sub-tank, and where is it made?
Order it as TOTO TLK01401U. It's manufactured in Japan. That's the single large-capacity sub-tank model, so there are no size or finish options to specify.
7) What color and material is the TOTO TLK01401U sub-tank, since it sits in an open vanity?
White plastic. If the vanity is open underneath or has a slotted apron, the tank will be visible, so most installers set it inside an enclosed cabinet or a service chase.
