Setup: Tolsen Force Express 79846 Peripheral Pump User Manual

Overview

The Force Express 79846 Peripheral Pump is a compact water pump designed for light-duty household, farm, and well applications. It is intended for clean water transfer only, making it suitable for shallow wells, cisterns, irrigation setups, and general water movement where a fixed, stationary installation is possible.

This model is built for users who need reliable pressure-style water delivery with straightforward installation and routine maintenance. The Force Express 79846 Peripheral Pump is not meant for dirty water, chemical fluids, or continuous decorative water features, so it is best matched to clean, controlled water systems.

Detailed Description

The Force Express 79846 Peripheral Pump moves water through a shallow-well style pumping system using a suction line, priming inlet, intake screen, and discharge port. It relies on proper priming before use so the pump body and suction line are filled with water and ready to build flow.

Key parts named in the manual include the intake, discharge port, drain plug, and priming inlet. The pump must be installed in a dry, fixed position with rigid support so the pipework does not carry the weight of the unit. For best results, it should be placed as close to the well head as possible and connected to properly sized 1-inch intake and discharge piping.

In practical use, the pump is meant to support clean-water transfer from shallow wells, cisterns, irrigation lines, and similar systems. The Force Express 79846 Peripheral Pump can also be used for general water transfer around the home, farm, or plumbing setup when the installation follows the manual’s limits.

Safety

• Use the pump only with clean water and never with fuels, cleaning chemicals, or other fluids.
• Keep water temperature at or below 77°F (25°C).
• Connect the pump only to a properly grounded 120 VAC, 60 Hz outlet protected by a GFCI.
• Do not use an extension cord.
• Install the unit indoors or in a weather-proof well house only.
• Never run the pump dry or allow the suction inlet to lose submersion.
• Keep electrical connections dry and elevated if flooding is possible.
• Protect the pump from freezing conditions.
• Do not use the pump in swimming pool areas.
• People with pacemakers should consult a physician before use.
• Keep children away from the unit and follow all basic electrical safety practices.

Setup and Operation

Before first use, the Force Express 79846 Peripheral Pump must be primed. Fill the suction pipe and pump body through the priming inlet, close the inlet after checking for leaks, and open downstream faucets or taps to let trapped air escape.

Installation should be completed on a rigid, level, dry platform that can support the pump and the water-filled piping. The intake and discharge pipes should be at least 1 inch in diameter, and the suction line should include a foot valve positioned below the pumping water level. A well seal should be fitted at the top of the suction pipe to help keep the well clean.

The pump should be installed so the combined vertical well lift, offset line length, and delivery head stay within the maximum delivery height. Long runs should use larger pipe where needed, and the inlet and discharge lines should not place strain on the housing.

To start operation, confirm that the intake is submerged, the outlet is GFCI protected, and the power connection matches 120 VAC at 60 Hz. After plugging in, run the pump for about two minutes. If water does not flow, disconnect power, prime again, and restart.

Cleaning and Maintenance

Routine maintenance helps the Force Express 79846 Peripheral Pump stay efficient and extend its service life. Under normal conditions, the manual recommends maintenance at least every three months, with more frequent attention in dirty or heavily used environments.

• Clean the inlet screen regularly to remove debris buildup.
• Wipe the pump with a soft damp cloth and mild soapy water.
• Avoid solvents and keep electrical parts dry.
• Disconnect power before any inspection, cleaning, or maintenance.
• Do not disassemble the pump or motor, since this can damage the water seals.
• Before storage, drain the water, remove the drain plug, and replace it after draining.
• Store the unit in a dry place and apply a light coat of oil to metal parts for rust prevention during long storage.
• After storage, check that the impeller turns freely and is not oxidized.
• If the pump has been moved during operation, flush it with clean water afterward.

Troubleshooting

If the pump does not start, common causes include no power, thermal protection shutdown, or a blocked impeller. If it runs but does not move water, likely causes include loss of prime, excessive lift, a submerged intake problem, air in the suction line, or a clogged inlet screen.

Low flow often points to undersized piping, dirty liquid, excessive lift, or friction from corroded piping. If the pump will not hold prime, look for a missing or leaking foot/check valve. Bubbles at the outlet usually come from temporary air purge after setup, suction-side leaks, a gaseous well, or the water level dropping below the foot valve.

When water flow is unstable, check for improper priming, air leakage, frozen pipes, dirt or sand around the foot valve, or a clogged foot/check valve. If the pump does not shut off, possible causes include welded pressure switch contacts, a leaking fixture, a clogged impeller, a pipeline leak, or a faulty foot/check valve.

Recommended corrective actions include re-priming the pump with clean water, tightening or sealing suction-side joints, reducing lift, thawing frozen piping, cleaning the impeller and screen, and replacing worn valves or damaged piping. Pressure switch adjustment should be handled by a qualified technician, with the switch set to 30 PSI start and 50 PSI stop where applicable.

Any electrical fault, motor cooling issue, or impeller obstruction should be handled safely with power disconnected, and the pump should be serviced by a qualified technician when repairs are needed.

Pros & Cons

• Pros: Compact shallow-well design, clean-water performance, good maximum delivery height, simple 120V operation, and clear maintenance requirements.
• Pros: Suitable for irrigation, cisterns, and general water transfer when installed correctly.
• Cons: Not for dirty water, chemicals, or continuous fountain use.
• Cons: Requires priming, proper suction setup, and careful installation to avoid dry running or loss of prime.
• Cons: Must be protected from freezing and cannot be supported by the piping alone.
