“Do you need a vintage plumbing part and nobody seems to be able to find it in your area? Save yourself time and hassle and go to Noel's Plumbing website. You can text them a photo of the part and they will find it in minutes and give you the link to order it, all at a competitive price. My plumbers seem incapable of doing this and hand the job off to me. What can you do? But Noel's always has the 1930s parts I need or the aftermarket part that will get the job done. If I need it fast I can get it in 2-3 days from them and they know exactly what they are doing. It's a good old-fashioned plumbing store with all the parts you could possibly need and people who know how to get them. The service is top level. The staff pick up the phone after one or two rings. They are polite and KNOWLEDGABLE. I'm so tired of dealing with folks who can't find a chicken in a hen house. LOL. ”

Specifically designed for use in cast-iron fittings where the threads have been damaged, the Test-Tite Flush Mechanical Cleanout Repair Plug restores functionality to cast-iron cleanout tees. This cleanout plug features an innovative design that creates a seal with the smooth surface behind the damaged threads to provide an airtight seal. Compatible with all brands of cast-iron fittings, this repair plug sits completely flush inside and out of the tee and cannot fall into the pipe. Once installed, it creates an airtight seal that holds up to 50 feet of backpressure. A stainless-steel flathead screw and wrench are included.

We can ship anywhere the US Postal Service ships. For orders being shipped outside the US, please contact us at (888) ASK-NOEL, noelsplumbingsupply@fuse.net, or via the text widget on this screen.

“Hey these guys are awesome! If you need a part for a fixture they have it send a picture and they can tell you what it is, they know their stuff, they have the weird obscure things you can't find unless you get a whole trim kit or whatever. Worth the trip and the money. They save you tons of time definitely visit ”
