As a lifelong resident of DFW, I can say that this is THE PLACE to go for your plumbing parts needs. I've been doing my own work (when I feel qualified) for over 40 years and, from the first time I was told by a friend to come here, to every return visit, they have had the EXACT parts that I needed.You might get lucky and find the same part at the big box stores, but when you go to Teter's, you can rest assured that they WILL ALWAYS HAVE THE PART IN STOCK. The prices are also right in line with the big box stores.If I had to find a fault, I guess it's the fact that they aren't open on Saturdays, but hey, I like my weekends off work as well.
