So I am currently redoing my downstairs bathroom (in brief for those that don’t know: completely gutted and replaced with awesomeness). Cecily and I found what we considered to be the perfect faucet at Lowes: AquaSource #0476590A with pull-down sprayer.
The problem is, I installed it, and somewhere along the line it started leaking on the top side of the sprayhead. Fortunately, I kept the documentation, gave the AquaSource customer service department a call, and told them the part I needed (which was clearly listed in the documentation). They told me there was no charge, and the item would be shipped out this week.
Talk about flooring me. I’m honest, so being as I didn’t know what caused the problem (me or factory defect), I was expecting to pay for it. Since I just got off the phone, there may be updates to this post, but assuming the part comes as expected (which I have no reason to doubt at this moment), now would be a good time to read this post’s title.

Hi, Do you have the number that you called for AquaSource? I have the same faucet and it stopped working and I misplaced my paper work. I have been given the run around between lowes and an Aquasource manufacturer that did not make this faucet. Apparently there is more than one company who produces AquaSource. If you still have the number it that would be amazing and help my head ache.
Thanks so much,
Nicole

I don’t have the number off hand, but a Google search turns up this one: 1-866-538-5535
If I don’t forget, I’ll look up the number when I am back where the docs are.

Thank you,
Yes that is the number I called before. Unfortunatly that company isn’t the one who made my faucet.

You’re in luck — your comment reminded me while I happened to be home.
The phone number is 1-866-237-3907 and they’re open 7am-7pm EST (according to my docs) and their email address is CS@partshelpers.com
Good luck!
