“I spent the balance of 3 days looking locallyfor a replacement head for our Kitchen sink...only to find these guys with an exact fit and finish and lower than market pricing...I immediately ordered (an awesome website with smooth cart checkout). 20 minutes later I find a blown out gasket/ring that I was able to replace, and avoid having to replace entire spray head. I text there support line ( while the store was closed!) Requesting the order to be canceled. Within minutes and without hesitation or questions they had refunded my card and canceled the order. They have one of the largest online inventories, notably stocking harder to locate stuff and boasting a separate text line dedicated to recieve customer pics of parts/gear to ensure we are getting exactly what we need. Enough said. Bring your future plumbing problems/needs here and trust you will be taken care of...I know I will... @ Noels, thanks for continuing a tradition of honorable business practice, in a world that is littered with allot less... ”

“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. ”
