Had new tub and faucet installed just two years or less. Plastic handle has broken and replaced twice. The stem inside breaks making it unable to turn the water off.
Having used other peoples similar facets, the one that is breaking does not turn easily, it is very stiff to turn. Second thing is that this faucet slips some before it does anything when you turn it which I think adds to the problem of it breaking. The washer for the handles screw is way to large so that the head of the screw is only touching 1/3 of it.
This is a Moen faucet.

Men at Lowes said that it may need to be greased, OK, where and how, what kind of grease?
Someone said there may be an adjustment, OK, where and how?
I hate plumbing! I know nothing about it. And now I don't like Moen much either

I do not relish having a plumber charge me $100+ for something that is probably a few minute fix.
