Perfect exact replacement. I needed to replace rusted threaded pipe on my well and decided I should replace it all after 28 years. No one locally sold this tank tee for retail. It was only available wholesale or through a well company who of course wanted to do the service as well. Fortunately I found it online so I didn’t have to do some weird plumbing loops to make the brass ones work in the space I had.
Very happy with these brass tank tee. I had old galvanized stuff removed and all the plumbing and well companies only had this part in galvanized again.
I didn’t want more galvanized parts again in my well setup. They corrode from the insides out.
Very happy with this tank tee from Merrill.
Thanks again for the quick shipping of the item.
Well made which made installation simple.
In most cases, yes. As long as thread sizes and types match, they work with standard pressure tanks from major brands.
Yes—if you can drain the tank, remove the old tee, and thread in a new one with proper sealant and torque.
Match the tee’s tank-side thread, commonly 1¼", 1½", or 2", to your tank boss. Match the system-side NPT connection to your piping, such as ¾" or 1".
No—but it makes installations cleaner, reduces potential leak points, and simplifies the pressure tank system.
Most standard pressure tanks are compatible. Match the size, thread type, and connection type to your system.
Kits include preconfigured components. Individual tees are better for custom setups where you want to select each part.
For someone experienced with plumbing or water-well systems, installation is generally straightforward.
Built for DIYers and professionals who want clean, reliable pressure tank connections without unnecessary leaks, clutter, or guesswork.
