I bent a piece of pipe to deliver back to the tun. Inside the tun I had a piece of silicone tubing to deliver wort on to of the mash, but not so it delivered directly down.
Like I said before...sorry..don't know what to say. I crash after FG is reached plus another 11-18 days roughly, and spunding psi never drops... And I finish with perfect carbonation...Yay for me Hunh? :)
