Municipal/City Water Systems
Franklin now has an affordable answer for homeowners not satisfied with the water pressure they receive from their city water provider. The Inline 1100 is a simple, efficient product that provides pressure to every fixture all the time.
Private Well Systems
The Inline 1100 provides a constant pressure solution for homes with low yielding wells, where storage tanks or cisterns are used.
Want to add a sprinkler system?
The Inline 1100 is versatile and can be used in place of the standard booster pump often needed for a sprinkler pump system. In addition to its weatherproof NEMA 4 electronics enclosure, the Inline 1100 will adjust the overall system pressure, allowing complete water coverage and shorter system run times.
