Was sent the wrong parts and it took a solid week for Sprinkler Supply Store to correct their mistake. It's odd that they sent all shipments, including the return of the wrong parts, via FedEx, but when it came to them correcting their mistake and trying to earn back some credibility, they sent the replacement parts via slow boat USPS. They were quick to acknowledge their mistake, but they failed to ship out replacements the same day. In summary, Sprinker Supply Store made an error, acknowledged it, but acted halfway helpless in trying to make it right. Couldn't ship out the replacements quickly and couldn't ship via FedEx. Poor!
