Home Depot told us the water test would take 45-60 minutes MAX. It took 90 minutes! Whatever chemicals were used to test the water left our sink drain extremely stinky with a horrible chemical smell that we just can't get rid of it. Were also told this was NOT a sales pitch, just a water test, and that the rep would only try to sell us a product if we asked questions. Not true. The rep was very nice, but didn't necessarily know much about the testing. Could tell he was new at it. And the water softeners he tried to sel usl are WAY TOO EXPENSIVE! Can find much cheaper at Home Depot directly. Funny their product isn't even sold at Home Depot! Happy to have the water tested for free, but not what we expected at all.
