What precaution helps prevent a hose from twisting when a system starts?

• A. Ensure hose is not twisted.
• B. Tighten fittings beyond hand tight.
• C. Route hoses near electrical wiring.
• D. Use extra length to coil the hose.

Answer: (A)

Preventing hose twisting as a system starts comes down to keeping the hose aligned and free from torsion. The best precaution is to ensure the hose is not twisted before the system is activated, with the hose laid out straight and routed so it can extend without adding torque. When the hose is free of twists, startup pressure won’t pull on a twisted length, which reduces stress on the hose and fittings and helps maintain a safe, leak-free connection. Tightening fittings beyond hand tight can damage threads and seals and doesn’t address twisting. Routing hoses near electrical wiring is unsafe and hazardous. Using extra length to coil the hose can create more twists or kinks during startup and maintenance, not prevent them.
