Last week, for the first time this season, I used the frost-proof sillcock that's mounted on my garage. It wouldn't turn off afterwards and a disassembly showed the aluminum stem's threads had disintegrated. It is three-years-old, but I wasn't expecting to have to replace it so soon as the previous one lasted over 20 years.
I looked at Lowe's website to see if they had the same unit in stock, figuring I could just change the stem and not have to de-solder and reinstall the entire sillcock. I found the item and read some of the reviews and most negative reviews were for the same corrosion problem of the stem.
Rather than leave another negative review, I called the number that was posted by customer service under every negative review. I explained that I was two years out of warranty, but had incurred the same corrosion problem as many others. "No problem sir! Let me have your name and address and I'll ship you a replacement stem made of brass." No receipt, no questions, no hassle, no charge.
That was late Thursday. I received the replacement stem today and I'm smiling!
