Default Grain getting into kettle....

Setup:

10 gallon Rubbermaid
Morebeer false bottom
Batch sparging
Grain crushed by LHBS, approximately 65% efficiency

I must have recirculated about a gallon, out of the spicket, through a pot strainer over the mash via a pot strainer to not disturb the grain bed, STILL get a bit of grain into the kettle, which I am catching via a paint strainer bag. I'll post pictures when done so u can see how much.

Normal? Am I doing it wrong?

Preliminary guesses before picture is hosted?

Is your false bottom flat? A bent one will let grain through.

i experimented with a no vorlauf brew and the grain in the boil had no negative effect at all. worries about tannins are overblown in my opinion, it's not like you're boiling pounds of grain. is your false bottom metal or plastic? it may have collapsed.

I strain mine through a hop sack and it helps a little but u still get fine material and some hops, but that's unavoidable. Everyone gets that trub

Is the false bottom the right size? It should completely cover the bottom of the cooler. You need a 12 " diameter one.
Is the false bottom warped? If you set it on a flat surface, the edge of the false bottom should be touching the surface all the way around.
Is the bottom of your cooler warped? If so, then you will either need a new cooler, or you will have to live with a few grains creeping under the bottom.
How deep is the barb set? You may be able to raise it off the floor a little by adding some SS washers between the false bottom and the flange on the barb that mates against the false bottom.
Do you move the cooler between doughing in and finishing the sparge? After finishing the sparge, I move mine to the kitchen sink to drain out any extra water, and when I open the spigot, I notice a lot of grains come out.
Having said all that, I don't think that the amount of grains getting through will make a noticeable difference to the end product.
