The Parts You Need Winterize Your Spray Rig

November 14, 2019

We’re proud of our wide range of customization options and our high level of post-sale customer service, so we talk about those a lot. But did you know that we also offer a huge selection of parts? More than 1,800, in fact. We know that when you need a part, you really need it, so we’ve sped up the shopping process by putting our 40 most popular items here on our website, where you can order with just a few clicks. But all of them are available with a quick call to 800-543-2810 or an e-mail to parts@grahamse.com. We can ship most orders the same day.

This time of year, it’s time to start thinking about winterizing your spray unit. Any water that remains in any part of your equipment may freeze and expand, causing serious damage to pumps, regulators, and other important components. Robert Perkins of our Parts Department has compiled a checklist of items that he recommends you have on hand ahead of time to make winterizing a snap when the time comes.
