Questions and Answers for Wayne 1/3 HP Cast Iron Submersible Sump Pump with Vertical Float Switch

A:  This pump is not designed for outdoor use. The pump that might work for you would be the EEAUP250 utility pump. It is an automatic on and off unit.

A:  The CDU800 carries a Three year warranty. Should you need to use the warranty you will need your receipt/proof of purchase and the serial number of the pump. The serial number can be found on a white tag zip-tied to the power cord. We strongly suggest you leave this tag attached to the cord. If you have any additional question please let us know.

A:  The recommended basin size for the CDU800 vertical float switch style pump is 22" deep and 11" wide. The depth and width will vary according to model number or style of pump.

A:  This pump is 12" in height. They are designed to be used indoors in a basement sump pit to pump clear run off rain water that has filtered down thru a drain tile. Usually the drain tile empties into the pit towards the top. (Installation illustration in the manual) This is why we recommend the pit to be a little taller to allow room for the drain tile to drain.

A:  The mechanical float switch is rated for a million cycles.

A:  The float has a differential built in so that it does not cycle more than needed. This is a good quality pump.

A:  These units can be used in crawl space as long as they are pumping clear water only. The unit will come on when the water level reaches 9" from the bottom of the pump and shut off when the water level drops to 4" from the bottom of the pump.

A:  If the enclosed space holds water 6”deep or more it should work. Level the pump to operate properly.

A:  I don’t believe that will work. There is a 3/4-1” rise from the floor to the top of the base so you’d end up having at least an inch of water before the pump would begin to pump. My suggestion is to use a pool pump that will pick up water as it begins to accumulate. The negative side of this is that you have to manually plug this type of pump each time you want it to work.  Hope this helps 

A:  The new Ridgid submersible sump pumps will have the 4 screw cap.

A:  The newest models with have the 4 small Phillips Head Screws holding on the switch cap. The older style only had 3 Phillips Head Screws holding on the switch cap. The floats and rods are the same size but the colors have changed.

A:  It will not hurt the pump, it will reduce the flow rate which may not be a problem in this case.

A:  The sump pumps are designed with a 1 1/2" discharge. They can be reduced to 1 1/4" but no smaller. By reducing the pipe down smaller, you cause a back pressure on the pump and will damage the motor. Also, our sump pumps are designed for clear water only. Discharge from a Water Softener is considered brine water and will damage the pump and void the warranty.

A:  The Wayne CDU790 pump has a 3 year warranty for manufacturing defects.
