I have a house which was built in 1965 and i need to repair the bathroom faucets. the problem is that when i try to repair the faucet i can not remove the little round thing on the front of the faucet handle to get to the screw inside. how can i remove this ?

Double handle controls, correct? Stamped metal? Thin and can be fragile, but will take some abuse. Okay, take a putty knife, or thin blade flat screwdriver, and place it in the groove that should be about 1/8" inch from the faucet handle top, hold that at about 25 degree angle, and strike the handle of the putty knife or screwdriver lightly. I don't mean a touch like tap, but don't take a mighty swing at it either, Just a little tap, or two, and any corrosion, rust, ect. should let go and the cover should raise a bit. In the alternative, if you can't get them to move or pop off, you can drill through the top of the handle with a 1/2" bit, and reach the phillips screws that hold the handle on that way. replacement knobs are available at Lowes, Home Depot, 84 Lumber, ect. But if the covers are stuck that tightly, then the handles probably are too, I've actually had to use vise grips and destroy the handles to get them off, and then replace them. Just be a bit patient, and they should remove. And if you have to drill them, only drill through the cover plate. About 1/4" should do. Put a peice of masking tape on the drill bit about 1/4" from the end and drill slowly and stop when it goes through. Otherwise you may mess up the phillps head screw that lays underneath. The replacement handles are pretty inexpensive, and if yours are pitted, scarred, rusted, or lost their luster, these will brighten the faucet area nicely. Plan on spending around 6 to 8 dollars for replacement handles. Still, thats cheaper than a faucet replacement.
