This would make sense if your volume use is high. If existing system is used just for dispensing glass to glass for a home party, this shouls suffice. If you are going to blow through several kegs in a short duration of time, you may want to invest in a 100' 3/8" OD coil with about 20' 1/4" OD behind the faucet with about 30 PSIG. This set up is used often at big special events such as fairs, rodeos, football games, etc. If you want to plumb two coils together, a beer "Y" is available for the top of a coupler. A concern would be how much pressure it would take to propel the beer through each coil to acquire a decent flow rate. Another option would be to join each coil with an adapter union. What coil system are you using know?
