Customer Questions & Answers

Best price?

This exact model is priced much lower in another "big box" store. Why should I buy from Home Depot?
Asked by: Shopper
Hi Shopper, here is a description of our Price Matching policy that can be reviewed on (linked below for reference): 'If you find a current lower price on an identical, in-stock item from any local retailer, we will match the price and beat it by 10%* (in-store only, low price guarantee). *Excludes: online purchases, special orders, bid pricing, volume discounts, open-box merchandise, labor and installation, sales tax, rebate and free offers, and typographical errors. Online purchases are subject to Price-Match only.’ Online price matching also would only occur to match new-in-the-box, ready for immediate shipment and identical, in-stock items from our online, retail major competitors and does not apply to in-store items, going-out-of-business sales, or discontinued, clearance, obsolete, seasonal, close-outs, used, open box, displays or distressed merchandise of our competitors. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot!

How to turn off the "low salt" warning light?

Asked by: GoRaidersq
Hello GoRaidersq, Below are the instructions for turning off the "Low Salt" warning light as well as a link to the manual for the softener. I hope this helps. To turn off "Low Salt" light: Press the p UP or q DOWN buttons to set the salt level to match the number on the brinewell. At level 2 or below, the “Low Salt" indicator light will flash. If you wish to turn this feature off, press the q DOWN button past 0, and the word “OFF” flashes in the display. Manual and Guide: Cheers, Chris
