TOTO THU073RX-A – Frequently Asked Questions
1) What is the TOTO THU073RX-A spud and where does it go on a commercial toilet?
The THU073RX-A is a 1-1/2 inch brass bowl spud for TOTO commercial toilets. It's the fitting that sits at the bowl's inlet and makes the connection between the flush valve vacuum breaker tube and the china, sealed by the spud washer. If you're rebuilding a flushometer-style water closet and the inlet connection is leaking or the old spud is corroded, this is the piece that gets replaced.
2) Will a 1-1/2 inch spud work with my flush valve, or do I need a 1 inch?
Size has to match the bowl, not the valve. The THU073RX-A is the 1-1/2 inch size, which is the standard inlet used on floor-mount and wall-hung water closets served by a flushometer. Urinals and some low-consumption bowls take a 3/4 inch spud instead, so measure the inlet opening on the china before ordering. If your existing spud measures 1-1/2 inch, this is the direct size.
3) Is the TOTO THU073RX-A spud made of brass or plastic?
Brass. That matters in a high-traffic commercial restroom where the connection gets stressed every time a flush valve is serviced, and where a plastic spud can crack under a wrench. The THU073RX-A is a brass part built for toilet bowl service.
4) Does the THU073RX-A spud come with a washer and coupling nut?
The THU073RX-A is supplied as the spud itself, a 1-1/2 inch brass bowl spud. Plan on checking the condition of the spud washer and the flush valve coupling nut while the connection is apart, since those are the usual sources of a weep at the bowl inlet and they are ordered separately.
5) Can I use this spud on a residential tank-type toilet?
No. A bowl spud only exists on flushometer-served fixtures, where a flush valve pipes water directly into the bowl. Tank-type toilets connect the tank to the bowl with a tank-to-bowl gasket and bolts, so there is nothing for the THU073RX-A to thread into. Use it on commercial water closets only.
6) What part number do I order for a TOTO commercial toilet bowl spud?
Order TOTO THU073RX-A. That is the manufacturer part number for the 1-1/2 inch brass commercial bowl spud, and it's the number to quote for a facility standardizing spare parts across a building's flushometer water closets.
