Frequently Asked Questions

Q. "What's the difference between simplex and duplex packaged systems?"
A.Duplex systems contain two pumps and are mainly used when high volumes are needed. The pumps will alternate while pumping low volumes and both pumps will work simultaneously to handle high volumes when needed.

Q. "What's the difference between indoor and outdoor duplex systems?"
A.Duplex systems designed for outdoor installations are very similar to indoor rated systems; typically the only differences are the control panel and the basin. Outdoor systems require a NEMA 4 rated control panel, while the indoor systems are more typically installed with a NEMA 1 rated control pane. Indoor systems typically discharge through the cover as they are often installed in basements, while outdoor systems are typically installed with discharges through the side of the basin. Please note: As the inlet depth is determined by code, the inlet and discharge locations will need to be drilled at the job site.

Q. "My automatic pump stops and starts constantly, how can I make the pump run longer?"
A.A pump short cycling is a function of the basin diameter and the "on/off" pumping range. Since the basin is in the ground it is unlikely that it can be enlarged. If you have an automatic unit which has a self contained float switch the "on/off" pumping range cannot be adjusted. But with a non automatic unit controlled with a pump switch you can have flexibility in the pumping range adjustment. Short-cycling can decrease the service life of a switch assembly. If this occurs, an automatic unit can be converted to operate with an external pump switch which will expand it's pumping range and decrease the amount of short cycling. Installing a check valve in the discharge line will help decrease short cycling.

Q. "Do I need to install a vent pipe to the tank?"
A.It really depends on how you plumb the piping to the tank and each situation is different. In many cases with any brand of sealed tank the simple answer is yes as you need air to displace the volume of discharge. An AAV may be used in many areas of the country but local codes always prevail and so best to check with your local code authorities before purchasing the enclosed tank system/s such as these shown on this page.

Q. "What is the 'Smart Pak' residential alternator?"
A. The Smart Pak residential alternator allows you to install two automatic pumps and provides extended pump life by alternating the pump use. The system also will run the other pump and sound an alarm if one of the pumps should fail.

Q. "What are 'alternating' pump systems?"
A. An Electrical Alternator is used on a Duplex pump application where automatic alternation of the pumps is desired for added protection in residential or commercial applications. With one pump operating to handle normal flow, a second pump becomes operational in the event the water level continues to rise. The built-in alarm system, a standard feature, can be connected to sound when the second pump becomes operational.
