What happens if my lines are longer than the recommended length?
Those formulas aren't always right, since they don't take all the variables into account. They rely on fixed resistance figures for various beer line sizes, but unfortunately those figures are actually variable.
The ONLY side effect to lines that are too long is a slightly slower pour. I always suggest getting lines that are much longer than you need. If I have time to drink a beer, I have an extra few seconds to wait for it to pour. If the pour really is too slow, it's super easy to trim a couple feet off. If the line's too short, getting it to grow a few feet longer is much more difficult.
For dispensing soda, you need really long lines (like 30'+), or other devices to increase resistance and slow the flow down. I use the epoxy mixer sticks in the diptube in conjunction with 20' lines for serving soda.
And even with longer lines you may experience a little foaming on the first pour since you left the keg on 20psi overnight. This surely increased the carb level some. When the carb level exceeds the serving pressure, CO2 likes to come out of solution slowly over time and form gas pockets in the lines, which often causes the first pour of every drinking session to pour foamy.
Another cause of a foamy first pour is the faucets/shanks being significantly warmer than the beer. As mentioned, if the faucets are located in your hot garage, they'll need a pint poured through them to cool them off before they'll pour well. Either that or some way to keep them chilled.
