My bathtub drain trip lever mechanism has failed, and my bathtub won't
The problem is, the heads of the screws holding the trip lever drain to
the tub are totally corroded away. Just rubbing the head with my finger
took off a bunch of rust and the heads are now stripped.
What's the best way to get the trip level drain cover off? Can I drill
out the screws without damaging anything else?
If you are careful.
Get some very high quality cobalt or carbide bits and see if you can get
a small hole drilled down the center and if so progressively increase
Be sure to wear safety glasses.
No, I wouldn't try to drill out those screw heads.
Those screws are SUPPOSED to be brass or stainless steel, and if they're
badly corroded someone has replaced them with ordinary steel screws,
which is why they're stuck.
Those screws screw into the overflow and drain assembly behind the front
of the tub, and if you can't get the screws out of the overflow, you'll
have to replace that whole assembly. That may mean cutting a hole in
the wall behind the tub to get at the assembly from the back or cutting
a hole in the ceiling below the tub to get at the assembly from below.
If it were me, I would use a Dremel tool (or any other such tool) to cut
the overflow cover off around the screws, and then apply diluted
hydrochloric acid to where the screws enter the brass overflow elbow
using an eyedropper or Q-Tip. Hopefully the acid will be drawn into the
crevice between steel male threads and bronze female threads amd
dissolve the rust there so that you can remove those screws.
Keep applying acid and twist the screw heads with a pair of vice grips
and hopefully you can get the screws out. Otherwise, replacing that
overflow and drain assembly is going to require you get behind the front
of the tub or you somehow gain access to that assembly from below.
Yes. Because they are rusted I assumed they are soft steel and it will
be child's play to drill them out.
I suppose with acid , penetrating oil or heating them with a torch they
/might/ come out with a vice grip but more than likely they'll just
break off... necessitating a drill-out anyway.
B4 you mount it on permanent spot, I'd suggest you try it out indoor and
get familiarize yourself with the camera. If it is not known name
brand, a generic thing, tech support is almost nil. I played with many
different IP cameras and running 7/24 on my NAS photo station.
I'd try what Oren says, including the tapping,
The description of the tool he lists sounds pretty good and gets a lot
of high ratings, plus quite a few low ones. But I've never used it,
have no experience with it.
I'm surprised no one suggested left-handed drill bits. Often when I
use those, while I'm drilling CCW, the screw comes out. Start with a
small bit, even if you have to use a clock-wise one to make the starter
hole, and get gradually bigger, but no bigger than the hole! (You can
see how big the hole is by looking at a new part at a hardware store. I
think they're all the same in a given country.) Home Depot has a
couple sizes of left handed bits by a famous maker and the only other
place I know that has them is Harbor Frieght, which sells a set of four
Oren's device is meant to run in a drill that's going counter clockwise
too. That's a good sign.
I think what all of us shoudl do is go around our homes loosening and
retightening every machine screw in the house, so we don't get stuck
like this. Starting.... NOW!
buy some lithium grease. Put some on
the threads of each machine or sheet
metal screw, to reduce the risk of
Locks, window cranks, refrigerator and
freezer door, oven hinges, door knobs,
door hinges. This list will be a good
start. Then, backs of radios and TV,
BTW, I don't reject the idea that those who gave it a negative rating
didn't read the instruction or had some other stupid reason to dislike
I bought a couple weeks ago a Big Red mini-floor jack, which got lots of
negative ratings, many complaining that it didn't go up high enough or
it took too many strokes to make it go up? What do you expect, fools?
It's a mini-jack with a short handle and a short stroke, and if you want
it to go up faster, you'll have to push harder than with other jacks.
OTOH, it does make this big noise going up at some point, and no one
complained about that. Still I like it.
This is the one with that's red with the yellow plastic handle. I don't
know if it last many years, but so far so good.
