Frequently Asked Questions

Q: How do I know if my S-Pump body kit needs replacement?
A: Signs include loss of water pressure, pump won't prime, water leaks from the pump housing, or the pump runs but delivers no water. If rebuilding the pump doesn't restore function, the body kit likely needs replacement.

Q: Can I use this kit for both my freshwater and wastewater systems?
A: Yes. This is a universal S-Pump body kit designed to work in both freshwater supply lines and wastewater applications, making it a versatile replacement option.

Q: Is this a complete pump or just the body?
A: This is the body kit, which includes the pump housing and internal components. Depending on your specific pump model, you may need to transfer your motor or other external components from your old pump.
