Visual Check: Regularly inspect elbow fittings for signs of wear, corrosion, cracks, or any other damage.
Leak Detection: Check for leaks around the fittings.
Exterior Cleaning: Keep the exterior of the elbow fittings clean to prevent buildup of dirt and debris which can hide potential issues.
Visible Damage: Replace elbow fittings immediately if you notice any cracks, significant corrosion, or deformation.
Leaks: If you detect persistent leaks that cannot be fixed by tightening or re-sealing, replace the fitting.
Flow Problems: If you notice a decrease in system performance, such as reduced flow rate or pressure, the fittings might be obstructed or damaged and need replacement.
