What is the max height that I could attain with the Shurflo. I need to cross a township road so I would need around 18 feet. I am planning on having near 100 taps ahead of the ladder. It will be around 1200 feet between the ladder and the Shurflo. I am planning on using 3/4 black plastic for the main line and 3/16 laterals and drops. Also how many 3/16 stars would I need for the top and bottom of the ladder.
