Plumbing — FAQ
Will a dual shower head reduce my water pressure?
Standard T-splitters reduce pressure 30-40% when both heads run. Patented tandem designs like the BOONA maintain full pressure by optimizing internal flow paths. Check GPM ratings and look for 'max pressure' claims tested at 2.5 GPM combined output.
Can I install a dual shower head myself?
Tool-free models install in 15 minutes using existing shower arms. Standard systems need adjustable wrenches and plumber's tape. Turn off water supply, unscrew old head, apply tape to threads, then screw on the new system. No wall modifications required.
What GPM should I look for in a dual system?
Aim for 2.0-2.5 GPM combined flow to meet EPA standards while delivering adequate pressure. Each head should deliver at least 1.5 GPM during dual operation. Lower GPM ratings indicate pressure drops or flow restrictors that limit performance.
Will these fit my existing shower arm?
All tested models use standard 1/2-inch NPT threads compatible with 95% of US shower arms. Measure your existing arm length—tandem systems need 2-3 inches of clearance from the wall. Handheld models require additional height for mounting brackets.
What's the difference between tandem and combo systems?
Tandem systems provide independent water flow to two fixed heads for simultaneous use. Combo systems share flow between a fixed head and handheld, requiring users to switch between them. True tandems cost more but let couples shower together without compromise.
How do I clean and maintain dual shower heads?
Soak heads in white vinegar monthly to dissolve mineral deposits. Clean diverter valves with a toothbrush to prevent sticking. Check hose connections quarterly for leaks. Avoid harsh chemicals that damage finishes. Most modern heads feature silicone nozzles that wipe clean.
