Quick quiet water tank filler

I replaced a 20 year old toilet tank filling valve with a ball float with this Danco unit and it's working great. It was a direct fit replacement, very easy to install, super easy to adjust the flow, and it's a lot quieter than the old valve. I like that the tube at the bottom helps to "clean" the bottom of the tank as it fills. During the install, I also replaced the toilet flapper tube and solved a pesky slow leak at the sametime. I hope I get 20 years out of this new unit 😉. FYI, I removed the toilet tank, clean it very well, and installed the filler and new flapper tube (a separate purchase) before re-installing the toilet tank and connecting up the water and doing final adjustments. I'm not a plumber and it only too an hour or two, as I took my time.

I looks good but I have not installed it yet and Danco is a good plumbing parts company but I have never had a part designed like this but it came intact even though packaging was crumpled but I suppose it works fine but I will install it soon
