Our Franklin 10GPM cistern pump provides high performance and long life for rainwater harvesting applications. Not to be confused with the C1 20GPM models (which are designed for septic tanks), the C1 10GPM is the only C1 model designed for residential primary water supply delivery. The C1 Series pump is able to pass solids up to 1/8" without having a negative effect on the internal hydraulic components.
The pump’s unique bottom suction design allows for maximum fluid drawdown without compromising durability or overall life, and it does not require the use of a flow induction sleeve. In other words, no pump casing is needed -- just drop the pump in the cistern, and you're ready to go.
As always, please feel free to call or email us with installation questions – we're happy to help!
Shipping is only $10 for U.S. orders! International orders will be charged an additional shipping charge, depending on the order size and address, after an order is placed.

The Franklin 1/2 hp 110v pump is amazing. Maintains two yard sprinklers and our cabin during the summer with no problems. Originally purchased this pump as part of the complete cistern system offered by Rain Brothers. Bought another pump for a backup in the event we ever need to replace original pump. Thank you Rain Brothers for providing quality products and excellent service. Joe on 9th Jan 2018
