Next by Danco HC660 HydroClean Water-Saving Toilet Fill Valve with Cleaning Tube

It’s been installed for a month now and it’s working well and it was easy to install. The only issue was the plastic nut had edges/flappers for easy turning and it was hitting the toilet tank and it was not easy to turn. But I got it installed and works great.

I wasn’t sure about the tank cleaning tube but boy does it ever do a good job or keeping the sediment from accumulating in your tank. Easy to adjust for water level installation was a breeze reasonably quiet. Really pleased with design

I went through 2 other flush valve retrofit kits from other manufacturers before I landed on this brand and model. It is by far the best quality with the most adjustments and seems like it would fit practically any toilet. It is dead simple to install and you may need pliers at most (I did not need anything, just some nitrile gloves). The self cleaning tube is not a gimmick either. When I installed mine for t he first time I had to flush 5 or 6 times because it kept flushing gunk out from the bottom of the tank. I highly recommend this product.

Works very good, there is no problem installing.I do like the valve overflow adjustment as we are on a well.

So to unlock it ypu have to push hard and twist it took me like 45 minutes even after watching YouTube tutorials because none of them mention that then it's an easy to adjust it afterwards. Even after installation. It keeps the tank clean. It's been a few months and it fillfaster and flushes better. I can't complain.
