"A little bit of water will be coming from the top of the fill valve and dropping back into the tank, part of the antisiphon action."
Thank you for this information that I found in another post. I installed a Korky Quiet Fill (like in my Toto at home) in a tank I recently rebuilt and installed in my camp. Glad to know the trickle from the top is normal and not a defect.
I like the construction of this valve, and will switch the other 2 tanks to them when the need arises.
Great GREAT site!! In fact I just sent the link to it to my new neighbors who have a water shortage problem and may be in the market for a new toilet. They will have everything they need to know from the information on your site to make a good decision!!
