Where is the serial number on this unit located? There was no sticker on the enclosed components, nothing etched onto the showerhead, and I did not see one on my printed receipt.

Item #5285424 | Model #3071-01618-PSCH

Hello, there is probably not a model number on the product itself. There should be an item number on the receipt that shows what was purchased and you can use the item number to pull the model from the Lowe's website. Thank you
