TOTO TH559EDV403R – Frequently Asked Questions
1) What exactly comes in the TOTO TH559EDV403R spout mounting kit?
TH559EDV403R is TOTO's spout mounting kit supplied with a longer nut and a lock washer. It is the fastening hardware that secures a spout down to the deck, not a spout or a valve body, so you still need the spout itself if that is what failed.
2) My TOTO spout is loose on a thick countertop - will the longer nut kit fix it?
That is what the longer nut is for. TH559EDV403R substitutes a longer mounting nut and lock washer for the standard hardware, giving more thread engagement under a deck where the original nut runs out of reach. If the spout itself is cracked or the thread on the spout shank is stripped, replacement hardware will not hold it.
3) Is TH559EDV403R a universal spout nut or TOTO-specific?
It is a TOTO service part, ordered by the TOTO part number TH559EDV403R. Spout shank thread sizes vary by manufacturer and by model, so match it to the TOTO faucet or spout you are servicing rather than treating it as a generic deck nut.
4) Do I need a lock washer separately with the TOTO longer spout nut?
No. The lock washer ships as part of the TH559EDV403R kit along with the longer nut, so there is nothing additional to source for the fastening itself.
