Adding a handheld shower diverter significantly reduces water pressure, and no diverter labeled 'full flow' restores the original pressure.

Existing diverters claim full flow but still restrict GPM significantly when used with typical residential shower heads, leaving no easy way to switch between fixed and handheld without pressure loss.

App Concept

FlowKeeper Diverter

A high-flow 2-way shower diverter engineered with a true 3/4-inch internal bore and minimal turbulence, preserving the original shower arm's GPM. Machined brass with smooth internal passages so you get full pressure to either head.

Key Features

True 3/4-inch internal diameter (not reduced to 1/2 at ports)
Full-bore ball valve design with no internal flow restrictions
Brass construction for durability and no corrosion
Compatible with standard 1/2-inch NPT shower arms and heads

Target Users: Homeowners and DIYers in residential plumbing, especially in low-pressure situations like multi-story condos, who want both a fixed shower head and a handheld without pressure loss.

Revenue Model: $34.99 per unit direct-to-consumer (online sales) with $49.99 premium finish versions, B2B wholesale at 40% margin
