“We were able to buy parts for our antique toilet here! Unfortunately, the toilet fell off the wall so we had to return the parts before we got the chance to use them. But returning was quick and easy! The staff is super helpful. ”

“The vacuum breaker on my outdoor spigot failed and Noel's Plumbing was the only placeI could find that had the appropriate mfr. part. I sent a text with photos on Wednesday evening to make sure the part I found was correct. In less than 2 hours later, I had a reply confirming it was the correct part. Placed my order that evening and received the part on Saturday afternoon (about 2.75 days) and my plumbing issue was resolved! I highly recommend - I really appreciated the prompt and pleasant response. ”
