Easy Setup

Very easy to install, takes a few tries to set at the right level but, not a big deal.

Toilet tank valve replacement

It was simple to install, after shutting the water off to the toilet and flushing a couple times to empty the tank. A sponge got the rest of the water left at the bottom of the tank. Installed the new valve after adjusting the height (per the directions). I cut the length I needed from the supplied rubber tube and connected it to the new valve. The only problem I had was spreading the clip to hold the rubber tube on the refill pipe in the tank. The new clip cracked, so I just used the old one....
