22/9/2014· In terms of the DEP water supply line size table, whose key component is gallons per minute, the differences are even more dramatic. Basing calculations of an average run of pipe of 50′, an 1 1/4″ line provides 16 gallons per minute. On the other hand a 1″ line only provides 9 gallons per minute. Therefore an 1 1/4″ line provides almost
