Danco HC660 HydroClean Details
Danco HC660 HydroClean toilet fill valve repair kit adjusts tank refill level and provides an audible alert when it detects a leak. Its cleaning jets stir debris in the tank and direct it toward the drain with each flush. The valve height adjusts from 11 in to 13.8 in and is designed to fit most standard toilets; confirm the existing valve's height and mounting arrangement before replacing it.

5Did the job and was easy enough to get working.
Nice and quiet
I’m happy with how quietly it refills.
Works like it should, and the tank fills up reliably.
A straightforward fix for the toilet. No issues so far.
Really pleased with this; the refill seems consistent now.
