There are two types of spray hose available for spray rigs: spiral one pass and spiral two pass.
On a spiral one pass, the nylon cord that holds everything together runs through the hose, beginning to end, once.
On a spiral two pass, the cord runs through beginning to end and then back, making a stronger hose.
“The decision is based on the amount of pressure you’re going to be putting through the hose,” says Gary Eichen, BioTurf/PHC manager at Mike’s Tree Surgeons in Troy, Michigan. “Spiral one pass is rated lower pressure than spiral two. I recommend for most cases, especially lawn care where it’s running 150 PIS to 250 PSI, the spiral one pass because of cost.”
Something to keep in mind is that hose pressure is determined at a temperature of 70 degrees Fahrenheit. If you’re working in a part of the country that is continually above that, your hose will be slightly lower in pressure because the heat makes the hose softer.
At J Rick Lawn & Tree, crews typically uses a hose that’s 400 feet long.
“When you have to go around houses and through gates, the smaller size makes it a lot easier to drag around obstacles,” says Jon Rick, owner of J Rick Lawn & Tree in Colorado Springs, Colo.,“Especially for residential purposes when you’re dragging it out and reeling it up 20 times a day. It makes a big difference.”
Eichen says flipping your hose once a year helps extend its life.
“In most cases, a technician is pulling out maybe 150 feet of hose,” he says. “Most hose reels come in 350-foot lengths so the last 150 feet is not used nearly as much as the first 200.”
