PlumbingPart Identification & Selection3MediumPlumber$ implied
A plumber needs a reliable way to connect a tub spout to a valve without soldering copper, avoiding PEX restrictions and lacking a pre-soldered FIP-to-copper adapter.
No pre-made adapter exists that has a female iron pipe (FIP) on top and a copper stub-out on the bottom for tub spout connections; plumber is forced to either solder copper or use non-recommended PEX.

App Concept
Solder-Free TubDrop
An adapter that connects a tub valve's male iron pipe (MIP) directly to a copper tub spout stub-out without soldering. It uses a brass body with a threaded FIP top and a pre-attached copper tailpiece, installed with a simple wrench. Eliminates the need for soldering and avoids flow restrictions from PEX.
Key Features
- Brass body with 1/2" FIP female thread on top to connect to valve MIP
- Pre-attached 1/2" copper tube stub-out (adjustable length, e.g., 6-12 inches)
- No soldering required - hand-tighten or use wrench
- Compatible with standard Delta and other tub spouts
Target Users: Plumbers and DIY homeowners installing tub faucets who lack soldering skills or want a quicker, code-compliant connection.
Revenue Model: $12-18 per unit wholesale, $25-35 retail at hardware stores and online
