Inline Dual-Pump Valve Assembly
Solar submersible pump integration component — the industry's first inline valve assembly enabling true off-grid zero-switch dual-pump well operation.
The Simple Pump Inline Dual-Pump Valve Assembly makes true inline dual-pump operation possible in a single well.
This proprietary check-valve tee threads your Simple Pump cylinder and compatible solar submersible pump together using standard NPT fittings. When the solar submersible runs, system pressure closes the valve ensuring all water is pumped through the system. When you operate the hand pump, minimal vacuum opens the valve allowing water to be pumped through the system.
No manual valve switching. No re-plumbing. No compromises.
The Inline Dual-Pump Valve Assembly is the critical connection component that allows a solar submersible and a Simple Pump hand pump to operate independently in the same string of drop pipe.
Compatible with Workhorse Narrow Series solar submersibles. Workhorse submersible pumps and Simple Pump hand pump systems sold separately.
The Simple Pump Inline Dual-Pump Valve Assembly is manufactured by Simple Pump in the USA and backed by a 15-year warranty. Valve inserts available for quick replacement.
Do You Need More Water than You Can Physically Pump?
Upgrade from manual pumping while keeping backup capability
Manual Pumping Fatigue
Hand pumping 50+ gallons daily becomes exhausting and time-consuming
Single Point of Failure
Submersible pumps leave you stranded during any power interruption
Emergency Preparedness Gap
When disaster strikes, you need water access regardless of grid status
Don't Wait for Emergency to Strike
The best time to install a backup water system is before you need it. When the power goes out, it's too late to wish you had prepared.
What the Inline Dual-Pump Valve Assembly Is
The Inline Dual-Pump Valve Assembly is a valve component — not a complete pump system. It is the connection piece that installs inline between a compatible solar submersible pump and your Simple Pump cylinder, enabling both to operate from the same string of drop pipe with no manual switching.
