Saddle valves are not recommended for permanent use. They should be used only as a temporary solution in cases where a regular shutoff valve is not available, and replaced with a more reliable option as soon as possible.
Advantages of saddle valves:
• Quick installation
• Inexpensive
• Easy to access parts downstream from the valve if needed.
Disadvantages of saddle valves:
• Low quality construction; prone to leaking or having other problems over time
• Not approved for potable water use by many local codes and regulations, so using them may result in fines or other penalties
• Risk of damaging piping when installed improperly.
