Saw a good deal at a local Home Depot for 20' sections of 3/8" copper pipe. What is the possible downside to soldering the two 20' sections together and using that? Do I really need to do a 40' immersion cooler or would 20' work fine for 5 gal batches? Most of the smaller ones I have seen start out at about 25'.
Thanks for the help.
