Review: Aerobic Septic System "PUMP DOWN" Float Switch - Little Giant RFSN-9 115-Volt, Maximum 13-Amp - 1/2 HP, Pump Down Piggyback Tethered Float Switch for Pond, Sump, Sewage or Effluent Systems, 15-Ft. Cord, Grey, 599117 Regular price $94.91 I'm an avid DIYer. Bought this float switch "Used-Very Good" three weeks ago for $32.83. Never been used! Had the original box been opened? Yes. Of course. But who cares? It works like a champ! Used it to replace my aerobic system lowest float switch, the one that fires up my Sta-Rite 1/2 hp 20 gpm sprinkler pump. Want to test it first before installing? Great idea. I tested mine for continuity THROUGH the piggyback plug, not lead-to-lead. (Check YouTube.) Then I cut off the piggyback plug and butt-spliced this new float switch with the existing wiring, using a wire connector crimper with butt splice head, plenty of assorted sizes of WATERPROOF heat shrink CLEAR tubing, an assortment box of butt splices, and wrapped it all up in 3M Super 33 electrical tape. (All these are, of course, available through desertcart.) (I actually had a double problem. My GFCI circuit breaker was bad, also, and I replaced it, also. Cheapest price was available at desertcart.) (I also took a course offered through the county Health Department which allows me to check my own septic system rather than hiring a septic service to come out every 4 months. I send in a report every 4 months and save about $300 a year.) Like I said. Works like a champ! Review: Dependable float switch - After replacing 2 cheaper switches over 3 years, I installed this one. This is a solid replacement switch with better materials and construction than most of the other cheap switches out there. Only slightly more expensive, you get quality and value for what you pay. Easy to install. Very dependable silent operation. Ejector pump operates flawlessly now. ## Features - APPLICATIONS: water resistant pump down tethered float switch for sump, sewage, effluent systems, ponds or utility pumps; allows pumps to start/stop automatically; adjustable - LIMITATIONS: maximum 0.5 HP; 13 Amp maxumim pump run current; 85 Amp maximum pump start current; use only with pumps equipped with integral thermal overload protection - CORD LENGTH: 15-foot cord with piggyback plug; pumping range 7 inches to 36 inches - TEMPERATURE RATING: maximum liquid temperature 140 degrees F - LISTINGS: UR, CSA listed in the USA; Made in USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000JG80WU | | Best Sellers Rank | #103,341 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #98 in Water Pump Accessories | | Brand | Little Giant | | Brand Name | Little Giant | | Circuit Type | 1-way | | Color | Grey | | Compatible Devices | pumps up to 1/2 HP with integral thermal overload protection | | Connector Type | 2 Pin | | Contact Type | Normally Open | | Control Method | Touch | | Control Type | automatic on/off | | Current Rating | 13 Amps | | Customer Reviews | 4.7 out of 5 stars 327 Reviews | | Global Trade Identification Number | 00010121991170, 00735090761813 | | Included Components | Product Only | | Item Dimensions | 3.04 x 3.04 x 4.13 inches | | Item Type Name | Pumps | | Item Weight | 1.5 Pounds | | Manufacturer | Franklin Electric Co., Inc. | | Material Type | Neoprene, PVC | | Model | 599117 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Operating Voltage | 115 Volts (AC) | | Operation Mode | ON-OFF | | Part Number | 599117 | | Specification Met | CSA | | Switch Type | Piggyback | | UPC | 735090761813 767654089972 010121991170 | | Unit Count | 1.0 Count | | Warranty Description | 1 year manufacturer | | Wattage | 373 watts | ## Product Details - **Brand:** Little Giant - **Color:** Gray - **Material:** Neoprene, PVC - **Style:** 15' Cord, 115V Plug, Max 1/2 HP - **Product Dimensions:** 3.04"L x 3.04"W x 4.13"H - **Power Source:** Corded Electric - **Item Weight:** 1.5 Pounds - **Maximum Lifting Height:** 36 Inches - **Voltage:** 115 Volts - **Global Trade Identification Number:** 00010121991170, 00735090761813 ## Images ![RFSN-9 115-Volt, Maximum 13-Amp - 1/2 HP, Pump Down Piggyback Tethered Float Switch for Pond, Sump, Sewage or Effluent Systems, 15-Ft. Cord, Grey, 599117 - Image 1](https://m.media-amazon.com/images/I/51W-ztQYOaL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Is this a normally open switch?** A: The float switch is normally open when the float/water level is down. **Q: can this be used for well s?** A: Yes, it is activated when the water level lifts the float up on its side causing the contacts inside the unit to connect causing the power to the pump to be activated. As the water level drops the contacts separate cutting the electricity. You set the float to activate by the length of the cord to water level. **Q: does anyone know what I can use to send me an alarm when the switch is closed?** A: Thank you for your interest in Little Giant products. I think what you are looking for is our High Water Alarm.

This is a switch. It turns the pump on and off. It doesn't actually pump the water. This switch is designed for pump 1/2 HP or less with a maximum 13 Amps.
