Moen Flo and water pressure

I bought a Moen Flo and then realized that it has a 3/4" connection but the main water line to my house is 1" so a reducer would have to be used. If you aren't familiar with the Flo this is it.

On their website Moen tries real hard to convince people that reducing to 3/4" will have minimal impact on water pressure. This is what I was told by support via email: At 60PSI you can get a maximum of 32.6 gallons per minute across the device. The pressure loss at, for example, 10 gallons per minute, is 1.7PSI.

I have no idea what this means for me. Would stepping down to 3/4" noticeably affect my water pressure? I have a tub filler that uses 7gpm and that's the highest capacity fixture in the house. Will I see a difference there or anywhere else?


In a few months Moen is coming out with a model that is 1 1/4" but it will be more expensive than the current model which is already quite pricey so if I had to get the larger one I might just pass on it.


Thanks in advance for any help!
