“It is so nice to see you guys are still rocking and providing the best service for unique plumbing parts. I first used you guys 20 plus years ago when my brother turned me on to you. I live in Nashville now and was searching the entire region for a particular cartridge and you are the only one that had it. Hands down there's not many like you and you've always provided a great service and I'm glad to see you doing it now even online! ”

“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. ”
