When to Purchase a Shower Replacement Regulator Kit


Important Details

If you have purchased a 1.8 Gallons Per Minute (GPM) Waterpik shower head and want to increase the water flow rate, our replacement regulator kit may be right for you.

How does the replacement kit work?

The kit includes a new 2.5 GPM regulator - the maximum flow rate allowed by Federal law. You can use the installation instructions below to remove and replace the existing 1.8 GPM regulator inside the shower head assembly, which will increase the water flow rate.

How do I know whether my shower head is a 1.8 GPM model?

Waterpik 1.8 GPM shower head model numbers end in "E" (VLG-669E).

Are there locations that do not allow 2.5 GPM?

Yes, the kit does not meet local GPM regulations in California, Colorado, or New York City and is not intended for use in those locations. To learn more about GPM requirements and flow rates, see Shower Head GPM.

Waterpik supports regulatory efforts to conserve water and encourages everyone to practice good water usage habits. To learn more about changing your habits to help conserve this precious resource, read our Simple Ways to Save Water at Home blog.
