“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. ”

“I sent in photos of a broken cartridge (still installed, couldn’t take it out myself due to water shut-off restrictions in a condo) and even with the limited view they were able to tell me the exact part I needed so I could have it ready for the plumber (meaning I didn’t need to pay for a plumber to come out twice!!) ”
