Hi - I have recently got an Angram Model CO handpump and refurbished it. I now have it pumping water well and I am ready to connect it to a (de-pressurized) corny keg. I will be using a 2psi aspirator valve on the gas post of the keg I am pulling the beer from. I have done a lot of reading and watching videos and have some questions.
There is a one-way valve in the bottom of the pump cylinder that is held closed by the weight of the plunger. It looks to me that beer (water at the moment) drains out of the 1/4pint handpump cylinder over a few hours. This doesn’t seem like a good idea to maintain good beer health in the keg. Should I add a one-way valve in the hose between the corny QD and the pump? Some videos recommend a demand valve and some a one-way or check valve. Does it matter where this is placed? Close to the pump or the keg?
The pipe recommended on a lot of sites is 1/2” or 7/16”. I can understand this if I was connecting to a true cask, but I am pulling it from a corny keg with the restrictive dip tube and ball-lock QD. Should I still use 1/2“ hose or can I use 5mm ID EVA barrier hose?
Any other recommendations or tips before I start hand-pulling my Best Bitter?
