To preserve the legendary performance and 70-foot range of your Stream Machine water launcher, consistent post-use care is essential. Because these launchers draw water directly into their mechanical cylinders, routine flushing and proper storage protect the internal seals from premature wear, chemical corrosion, and environmental damage. Follow this official guide to maximize the durability of your gear.
Whether your water battles take place in chlorinated pools, natural lakes, or ocean salt water, always perform a fresh-water flush before putting your launcher away. Chlorine, salt crystals, and fine organic silt leave behind residues that dry inside the barrel, causing the piston to stick and degrading the airtight seals.
To execute a thorough internal flush, fill a clean bucket with fresh tap water, submerge the front nozzle completely, and cycle the handle smoothly back and forth 15 to 20 times. If the rinse water becomes cloudy or sandy, dump the bucket, refill it with fresh water, and repeat the process until the water shoots out completely clear. If you have been playing at the beach, carefully rinse all visible sand from the exterior body before flushing to avoid drawing abrasive grit into the main barrel cylinder.
Storing a damp water launcher in a warm, enclosed space creates the ideal environment for mold and musty odors, especially if the device was filled from natural lakes or ponds. To keep your launcher sanitary and odor-free, always push the handle fully forward to drain all residual water, and give the unit a gentle shake to clear the nozzle tip.
If your launcher has developed a musty smell from improper drying, follow these remediation steps:
Prohibited Cleaners: Never use scented household cleaners, bleach, dish soap, oils, or chemical lubricants inside the barrel. These compounds will permanently warp the synthetic polymers and strip the factory seal lubricants.
While Stream Machine launchers are constructed from high-quality polymers designed for rugged outdoor play, extended exposure to extreme heat and UV rays will cause the materials to expand, fade, or warp over time. Avoid leaving your launchers in sun-baked sheds, vehicle trunks, or direct sunlight on concrete pool decks.
During the active summer season, store your cleaned and emptied water launchers in a shaded, well-ventilated location—such as a covered porch, a garage shelf, or beneath a deck. Always store the units with the nozzle pointed downward to allow natural air circulation to dry out any remaining internal moisture, and never seal a damp launcher inside an airtight plastic storage bin or bag.
Freezing temperatures are the leading cause of structural barrel cracking. If any residual water is left inside the cylinder during the winter, it will expand as it freezes, splitting the outer PVC tube or cracking the internal piston assembly.
Before packing your gear away for the winter, follow this off-season checklist:
