TOTO THU829-A – Frequently Asked Questions
1) What exactly comes in the TOTO THU829-A tank parts bag?
TOTO's THU829-A, sold as Drake tank parts bag #51, is a flush valve assembly for a 1.28 GPF toilet tank. It is the valve assembly itself, not a full tank rebuild kit, so a fill valve, trip lever or tank-to-bowl gasket set would be ordered separately.
2) Will the THU829-A flush valve work on a 1.6 GPF TOTO toilet?
No. The THU829-A assembly is specified as 1.28 GPF. Flush valve assemblies are matched to the tank's rated flush volume, so a 1.6 GPF tank needs the valve assembly TOTO lists for that model rather than this one.
3) What is the TOTO part number I should order for the Drake #51 tank parts bag?
Order it as TOTO THU829-A. That is the manufacturer part number for the Drake tank parts bag #51 flush valve assembly, and it is the number to quote so you get the 1.28 GPF version rather than another Drake tank part bag.
4) My toilet runs constantly and the flapper is sealing fine. Is replacing the whole flush valve the fix?
Often yes on a tank-type toilet. When the seal face or the valve body itself is worn or scaled, a new flapper alone keeps leaking by, and the THU829-A gives you the complete flush valve assembly for a 1.28 GPF TOTO tank rather than just the seal. Confirm your tank is the 1.28 GPF version before ordering, since this assembly is specific to that flush volume.
5) For a multi-family or hotel property standardizing on TOTO Drake toilets, is this the part to stock?
If the Drake units in the building are the 1.28 GPF models, the THU829-A flush valve assembly is the repair part to keep on the shelf, since a failed flush valve is the usual cause of a running tank. Properties with a mix of 1.6 GPF and 1.28 GPF Drakes need the matching assembly for each flush volume, so check the tank rating stamped on your units before buying in quantity.
