i have a constant drip which has become a constant flow of water from bathtub......i was going to replace the handles and the washers but when i went to take off the handle, the screw that holds the handle on to the valve, pretty much, went to pieces....there is no place to unscrew as i have a flat screw holding it on.
if i drill it out......will that take the handle out? or will i need something else? what size drill bit, and what type? i will probably have to replace the valve behind the handle as well (old house)......is this a job for a weekend repair guy or should i call a plumber?
thank you for any help or advice anyone can give....much appreciated.
You should be able to do it. Replacing valves usually isn't that difficult.
Turn the water off. Drill out the corroded screw with a drill bit about the same size as the screw, and remove the handle.
Then remove the valve and take it to a plumbing supply and get a new set of valves and handles and replace them both if they're that old and corroded. If you don't have a socket wrench that will fit the valve, you may need an inexpensive set of valve sockets made for the purpose to remove them.
That should solve your leaking problem.
If it doesn't, you may need to replace the valve seats in the faucet body too. You will need an inexpensive valve seat tool if so.
