I need to know what specs to look for in my particular situation. This copper line originates in the garage--Up thru the roof and into my Evaporative cooler...The cooler is a 2 year old Aero Cool equipted with an automatic water purge (for fresh water every 8 hours). The line itself is the same size you see on auto ice makers. The hammer noise is very loud. I'm in the desert so the cooler gets heavy usage May thru September. thanks...Mike
