WHAT OUR CUSTOMERS SAY…

“I was very happy with Noel’s Plumbing. I was searching for a fairly rare part and saw it listed on their website. After placing my order, I was informed that the item was actually on backorder. Noel’s Plumbing was upfront and honest right away, letting me know it might take some time to arrive. Throughout the wait, they consistently kept me updated, which I really appreciated. When the part finally came in, they shipped it out immediately. It arrived exactly as described and was precisely what I needed. Excellent communication, honesty, and follow-through. Thank you, Noel’s Plumbing! ”

These caps are used to seal the drain ports (also known as weep-holes or side overflows) on valves, which allows the non-pressurized side to drain without fully removing the cap. This is particularly useful for maintenance or winterizing plumbing systems.
