“I have come here as a maintenance technician countless times. NOT ONCE did these guys fail to impress me with their knowledge. They are across town for me and I don’t complain due to their unmatched service. I can bring in a busted chewed up cartridge or part and within 10 seconds the guys are like “ yup we have one right over here” and will bring me the exact match from what I had. Simply top tier. -SNS management ”

“These people were extremely helpful in taking me through replacing a 25 year old hard water frozen cartridge on my Philrich sink faucet. They were able to identify the correct part I needed from a photo I sent (I had it figured out wrong). I was pleasantly surprised they had an obscure part like this, but they also told me how to extract the old one when I couldn’t get it out. They said to unscrew it after I had concluded from YouTube the old cartridge was supposed to just slide out. It threaded out as they said and saved me buying a cartridge extractor and a hernia. The whole experience has been excellent. ”
