Weak Water Output / Hose Won’t Expand — Check Your PSIUpdated 4 hours ago

  • Low household PSI is the most common reason for weak output or failure to expand fully.

Expandable hoses depend on incoming water pressure, and U.S. homes typically supply 45-80 PSI, which is needed for the hose to expand fully. If pressure is low, the hose may only partially expand or deliver weak output. Remove the nozzle and run water through the open hose to confirm full flow. 

Check for kinks, obstructions, or mineral buildup. Silver Bullet supports up to 80 PSI, while Copper Bullet and Copper Head can withstand higher burst pressures, but expansion still depends on your water source.

Key Takeaways:

  • Confirm home PSI is at least 45 PSI

  • Remove nozzle and check flow

  • Inspect for kinks or blockages

  • Household pressure (not hose rating) controls output
