Simple Pump Inline Dual-Pump Solar Well System
Zero-switch solar submersible + manual backup pump from one well.
The Simple Pump Inline Dual-Pump Solar Well System is the only solar well pump system with true zero-switch operation.
The Workhorse Narrow Series solar submersible and the Simple Pump hand pump share the same well column through the proprietary Simple Pump Inline Dual-Pump Valve Assembly. No manual valve switching. No plumbing changes. Ever.
Solar panels power the Workhorse submersible for automated daily water delivery. When you reach for the Simple Pump lever arm, the valve shifts automatically, giving you immediate manual backup water.
Two fully independent water sources. One well. Zero switches. Water security without compromise.
Available through Simple Pump dealers and authorized Workhorse Pumps professional installers.
True Water Independence or Just Another Dependency?
Submersible pumps stop working when you need them most
Electricity Dependent Water
When your submersible motor stops, your pump system stops delivering water
Single Point of Failure
Submersible pumps leave you stranded during any power condition
Emergency Preparedness Gap
When disaster strikes, you need water access regardless of power 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.
Two Water Sources. One Well.
The Workhorse solar submersible pump handles your daily water automatically. The Simple Pump hand pump is always ready as backup — no batteries, no switching, no compromise. Available through authorized dealers.
Solar-automated daily pumping
Workhorse submersible runs 5–10 hours/day on solar power. No batteries required — direct solar operation.
Manual backup always ready
Simple Pump lever arm works independently at any time — even while solar is running. No batteries, no power required.

How the Combined System Works
Bottom to top: five components, two water paths, one well.
Workhorse Submersible Pump
Sits at the base of the assembly. Powered by solar panels on the surface. Runs 5–10 hours/day automatically. Pushes water up through the Simple Pump Inline Dual-Pump Valve Assembly.
Simple Pump Inline Dual-Pump Valve Assembly
Manufactured by Simple Pump. Connects the Workhorse pump to the Simple Pump cylinder via NPT threads. Opens under pressure (solar pumping). Closes under vacuum (hand pumping). The two systems share the water column without interference.
Spring Check Valve
Positioned above the Simple Pump Inline Dual-Pump Valve Assembly. Prevents water backflow when switching between modes.
Simple Pump Cylinder + Drop Pipes
Standard Simple Pump cylinder operates via the lever arm. Same 325 ft max static water level as a standalone Simple Pump — the submersible does not reduce manual capability.
Simple Pump Pump Head with Lever Arm
Sits on the well at the surface. Lever arm parked = solar is active. Lift the lever arm to pump manually at any time — even while solar is running.
Dealer Installation Required
Available through Simple Pump dealers and authorized Workhorse Pumps professional installers. Your dealer will size the solar array and configure the PSC100 for your well.
