A retirement house we built got several brand-new, out of the box, faucets (one for kitchen, hot & cold levers), several for baths & sinks. The kitchen unit developed a leak after 1-1/2 years. We could "fix" the leak by wiggleing the lever arm into some fairly sensitive position! As time went by, this got more difficult to do.
In an attempt to fix this, a trip to the hardware store showed a large number of these new and very very complex plastic inserts. None of the ones at the store matched what I had (and, I was out of warranty, no manual, no receipt situation).
Another faucet (bathtub, also new) is also leaking. Can't do any wiggling at all to stop it. Still another faucet is leaking about one drop every ten minutes.
All of the above are Pfister faucets. (their motto: pforever [I say: fooey])
Now, in talking with a friend, he tells me he has a new sink faucet only 3 years old and it's leaking. He took his apart, went to the store, got a new _insert_ and he says guess what, it leaks. Brand new insert! He returned it for a refund. Then he goes to one of the big box home improvement places, buys a new faucet, and, guess what, it leaks. I didn't ask him the brand.
Now, is this coincidence or are the manufacturers making defective products these days (in addition to all that stuff that breaks down sometime just after the warranty expires)?
Oh, yes, I did get a new faucet, and it looks like it drips about one drip per 10-15 minutes (I suppose this is the new technical specification of what the definition is of "faucet turned off"?).
And, this time I read the warranty, which requires that you save the coupon, save the original receipt, and something else that makes life difficult, and you have to send in the parts, too.
