This can of course vary with the specific valve but does anyone know more or less how much forward flow a one inch check valve can handle? I am probably pushing around 500 GPH and I don't want to loose too much of that.

Thanks

I have one on my 100g with a little giant 1300 gph pump and it didn't restrict it at all. I used a brass 1 inch check valve
