“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... ”
