TOTO THP3474 – Frequently Asked Questions
1) What exactly is the TOTO THP3474 part?
THP3474 is the case cover for the eWater controller used on TOTO toilet seats. It is the housing piece, not the controller electronics or the seat itself, so it is ordered when the enclosure is cracked, discolored, or missing rather than when the control board has failed.
2) Does the TOTO THP3474 case cover include the eWater controller inside it?
No. The THP3474 is the case only. If the controller itself is faulty, the cover will not correct the problem and you need the controller assembly instead.
3) Is the THP3474 for a TOTO washlet toilet seat or for a toilet tank?
Its application is the toilet seat side. The eWater controller it covers is part of the seat's system, so the part is relevant to seat service work rather than tank trim or flush valve repair.
4) How do I make sure I order the right TOTO eWater controller case?
Order by the part number THP3474 and confirm your seat uses the ECO/AC style eWater controller. TOTO service parts are model-specific, so matching the number printed on the existing case or on the seat's parts breakdown is what keeps you from getting a cover that does not seat on your controller.
