Your malts are off, should it be 2Lbs if Pilsner?
I use about 8 gallons of water for 5 gallon batches but only about 12 pounds of grain. I plugged yours into BrewersFriend and it calculates a 13% beer
They do the trick until you realize those stupid rubber feet on the lid closure are worn too! Had that happen on a couple of kegs after using the big white o-rings. I added a penny under and all sealed up
I have used their raspberry in the keg with great results. I blew co2 in the out dip tube to mix it all up from the bottom.
I too was tired of wasting beer.
