Zoeller Company does not recommend a simplex station on anything over two homes in order to maintain continuous service during unusual  

conditions.

Recommended Limits of Application X70 Series Grinder Pumps

These recommended application limits are for pump stations pumping to a gravity main.  Low-pressure pipe systems should be designed with a 

pump located at each house.  For applications where a lift station would handle between 15 and 60 homes, consider the 71 Series grinder pump.  

For applications where a lift station would handle more than 60 homes, a solids handling type pump should be considered.
