Default Cant Get The Last Gallon Out of Boil Kettle

So as I have upgraded to my 3 keggle setup, I am having a ton of trouble with efficiency as well as how much product I get at the end. any help would be greatly appreciated.

I have a 2- tier Herms system and am consistently getting around 70% efficiency but the bigger issue to me is that I am ending up with almost a gallon left in the kettle that the diptube is not picking up. I was tempted to dump it all through a strainer and then into my fermentor

Just wondering what else I can do to get more out of my beer

Thanks for any advice you all have

Yesterday after draining from my keggle to my fermenter I dumped into a 1 gallon container the remaining liquid and sediment and had about 1/3 gallon left over. My pickup tube though is in the center so I get more out with the downfall being it also plugs up my bazooka screen more. I probably will move my pickup tube to the side but then I may leave a tad more liquid behind.

I guess the question is: why isn't your diptube, if positioned correctly, not pulling all of the wort out of the keggle?

My diptube is arranged about 1/2" above the center spot of my keggle and would pull pretty much all of the liquid out if I let it.

The easy answer is to adjust the recipe for a gallon more and just leave it there.

Agreed, I just let gravity do its thing and pull out all that is needed.

some of it may be that as the kettle sets and liquid separates from the hops, I am ending up with the liquid I cant get into the fermentor. Yesterday I made a 11 gallon batch and managed to get 10.25 into the fermontor. one problem which I have fixed is that I was not calculating for the shrinkage within the kettle. My dip tub currently goes through a false bottom and rests roughly a quarter inch of the bottom of my kettle in the center.

When you drain out of the kettle into your fermentor do you have a hose connected to the ball valve? Or are you just waterfalling right out of the ball valve without a hose? My keggle diptube won't work without a hose attached FWIW.. Even with the hose attached it won't drain well unless I secure the hose to the hose barb on my ball valve with a hose clamp.

I agree, this helps a lot and makes a big difference as you get near the bottom of the kettle.

I have all Cam-lock Fittings and am using a 809HS pump, I have no issue with the pump once it is done pumping I just disconnect it from the kettle and lift it above my fermentor and any wort left in it drains right into the fermentor, however I still cant get that last gallon I may get rid of my false bottom on the BK and just use a hop spider than I can lift out of the wort and let drain while im chilling the wort down

This is because of the siphon. If you let air in, the siphon is lost. THus the need for the hose clamp. The hose on the output has to remain lower than the liquid it is sucking in order to completely drain (to the level of the pickup at least) the kettle. The bigger the drop, the faster the siphon.

+1 That your diptube should pick up everything as long as it's lower than the wort, assuming it is airtight between the end of your diptube and the end of the tube in your fermenter.

HOWEVER, nothing wrong with dumping that last bit directly into your fermenter, or through a strainer to keep the hops and hot break out. Hops and hot break will both settle with the trub, so as long as you are careful not to syphon trub when racking to your bottling bucket or keg, it doesn't hurt anything to have it in the fermenter.
