Toto Drake Drip Sound

[crete620]

I have had my Toto Drake for about 11 months and now I notice a drip sound that I cannot find the source or where it drips to. Sometimes when I flush a second time, the sound goes away. Any answers to this potential problem?

If it has the Korky fill valve, take off the cap and rinse it to see if there is any crud there. Reinstall. If that doesn't fix it, replace the cap. I'm assuming it stops eventually. Sounds like to me that the shutoff is not cleanly closing and drips a few probably down the overflow tube before it totally stops. For a short while after filling, water will slowly flow over the weir that determines the bowl water height. Think of it as a dam, or the lip of a teacup. The bowl is normally overfilled, and takes a moment to equalize after refill stops.
