How to remove the valve block for repair on my RakJak?

To remove part 2288 efficiently and without damaging adjacent components, begin by removing the top handle, which is secured with two zinc-coated hex bolts. Once the handle is removed, you will have access to the valve manifold. Using an appropriate wrench, hold the male-threaded brass hose barb securely in place to prevent it from turning. While the hose barb is supported, manually unscrew the female-threaded valve block by hand to detach part 2288.
