Kansas--It was very easy to pump AF through the water system. I purchased a small hand pump made for that by Camco and dipped the intake hose in a jug of AF while attaching the other hose to the city water TT connection. Then just opened each faucet 1 at a time while pumped until pink came out. each location= hot , then cold, starting at furthest point from connection.( kitchen sink for mine) Make sure you turn off water heater bypass first so you don't fill your HW heater. and don't forget outside and inside shower faucets. And also-- do NOT forget to pump pressure in line then flush toilet several times until pink comes out. After that which took 2 gallons, I used 3rd gallon to pour a few cups down each faucet drain, shower drain and toilet bowl. Took exactly 3 gallons for my TT and total time less than 30 minutes. Pumping was very easy.. only 1 faucet was open at a time. Have a spotter inside to tell you when pink comes out. It was a breeze!
