Guideline
Take into consideration the occurrence of unwanted noise
and vibration.
If the pump location is overhead, undertake special
precautions to reduce possible noise transmission.
Make sure there is a suitable power source available for the
pump driver.

4.1.3 Foundation requirements
Requirements
• A substantial foundation and footing should be built to suit local conditions and form a
rigid support to maintain alignment.
• The foundation must be able to absorb any type of vibration and form a permanent,
rigid support for the unit.
• Pour the foundation without interruption to within 1/2 to 1–1/2 inches of the finished
height.
• The top surface of the foundation should be scored and grooved before the concrete
sets. This provides a bonding surface for the grout.
• Provide a flat, substantial concrete foundation in order to prevent strain and distortion
when you tighten the foundation bolts.
• Sleeve-type and J-type foundation bolts are most commonly used. Both designs allow
movement for the final bolt adjustment.
• Allow the foundation to cure for several days before you proceed with the pump
installation.
