How to Increase the Flow Rate of a 2.5 GPM Shower Head

Both handheld and stationary shower heads have flow restrictors.

Most showerheads in North America have a flow restrictor that limits the amount of water that can pass through the shower head to 2.5 gallons per minute, or GPM. Recently, these flow protectors have become mandatory in an effort to conserve water. The flow restrictor is located inside of the fitting that connects the the shower pipe and literally blocks the flow of water to slow it down. The flow restrictor can be removed to allow more water pressure to flow through the shower head.

Things You'll Need

• Rag
• Adjustable wrench
• Flat-head screwdriver
• Teflon tape
• Scissors

Instructions

1. Turn off the shower faucet and make sure handle is securely in the "off" position.

2. Wrap a rag around the top of shower head and grip it, turning counterclockwise until the shower head has been removed from the hose or pipe. If your shower head is secured by a hex-nut, loosen the nut using an adjustable wrench.

3. Turn over the shower head and look for the screen located inside of the fitting.

4. Remove the screen by lifting it out of the fitting. If the screen is wedged in place, use a small flat-head screwdriver to remove it.

5. Wrap the threading of the shower pipe or hose with Teflon tape to prevent water from leaking from the connection, and then thread the shower head back onto the pipe or hose.

Tips & Warnings

• Be careful when removing plastic shower heads, as the heads may crack or break if you apply too much force.
