How easy is it to remove the original one? Thx

This is very easy. Turn off the water valve and then flush the toilet to drain the water from the holding tank. Then unhook the 2 rubber prongs and the pull chain and remove the old flapper, With the new flapper, hook the 2 rubber prongs and then hook on the pull chain. Turn on the water valve and fill the tank and you should be ready to go.

How do I find the model number on my existing AquaSource toilet?

Hello. The toilets should either have a stamp or a sticker. usually on the inside of the tank wall.

Does this one have a little hole on the bottom?

It does have a hole in the bottom & it’s a 3” flapper made for Lowes aquasource toilet.

Will this flapper work on a Gerber toilet, 1.28 gpf, Part # 99-770?

This is the flapper on my Gerber toilet. Toilet was bought and installed by plumbing company (never heard of Gerber brand before). I just bought this flapper as a replacement since part number was listed on existing one. Hope this helps
