What angle should be used when tapping a main water line?

When tapping a main water line, the recommended angle for the tap is typically in the range of 22 to 45 degrees. This angle is optimal because it allows for a secure fit and helps minimize the risk of compromising the integrity of the existing line. Tapping at this angle facilitates a smoother connection with less likelihood of creating stress or turbulence in the water flow. Moreover, it ensures that the new connection can handle the pressure without causing leaks.

Angling too shallow, as in the lower range options, may result in a weak or insecure tap, while a steeper angle could risk damaging the existing line or producing an inadequate connection. Thus, this range of 22 to 45 degrees strikes a balance between effective installation and maintaining the system's overall integrity.
