We purchased a new Delta kitchen faucet from Home Depot (Canada) about 6 weeks ago. We noticed it started making gentle squeaking sounds when the handles were turned. The squeaking sounds were like rubber rubbing against something in the handle or cartridge - you could feel this as you turned the handle. The HOT side is more pronounced than the cold side. The faucet seems to work fine. However, we did expect a smooth operation rather than this. What does this mean and would this contribute to early wear and tear? If so, any way to tell how long till problems occur? We still have a chance to return the item if needed.
