I had the green egg shaped ones with the teacher weight on the wire. I have a 230v pump with dual or double float set up ( both up = ON, both down=OFF ) the upper ( on ) switch would stop working within a few months to a year. It drove me nuts why they wouldn't last so I switched to these sludge boss type and they have been working great. I'll update my post in a yr or so to follow up on how they are still doing but so far...... they are great and have fixed my issue. Review: Three wires for filling or emptying.

As you mentioned, we rate the Sludge Boss float switch at 1/2 HP 13 amps 120VAC. A 3/4 hp pump will run nominally at 8.5 Amps @ 110VAC, but at startup or under load, the amperage draw of the pump will exceed the circuit rating of the float switch, which will cause premature failure of the float switch wiring and the Honeywell microswitch inside the float. The easiest work around for your application is to use a contactor or relay. Please contact us directly for more information on our Sump Alarm website, or @ customerservice@sumpalarm.com We have a contactor we can recommend to install in parallel with this float switch to accommodate your 3/4 hp or larger pump in addition to a wiring schematic.

Kyle H Applications Engineer, Sump Alarm EI, BSME '17 **Q: Will this float work in place of a septic products inc (spi) 20a702 pump down float switch?** A: According to the Spec sheet for the 20a702: | 20a702 | SludgeBoss | ---------------------------------------------------------------------------------- Cord Length | 10' | 16' | Operation | Pumps Down | Pumps Up or Down | Counterweight | External | Internal | Technology | Mercury | Microswitch | Environmental | No | Yes | Max Amp Rating | 5 AMPS | 13 AMPS | ---------------------------------------------------------------------------------- The float referenced from SPI is a control duty float that is made to be tethered. The Sludgeboss is internally counterweighted and does not require a tether. For the Operation to Pump Down, cap the blue wire coming from the sludgeboss. Let us know if this answers your question. **Q: I used this to replace my "high" float in a 3 float system (high, low, alarm). the affluent level never reaches the low float. replace both floats?** A: If it doesn’t reach the low float you may have other problems **Q: I have a Berkeley lift pump 5 horse 240 volt ,will this work for our application?** A: In that application, you need the Sludgeboss to control a relay or starter, and the relay or starter will control the pump. 240 volt applications have 2 hot legs, each 120V. Thats how they make the 240 Volts. Its really -120V and +120V, the difference between the two is 240 Volts. You need both those HOT legs to be opened and closed at the same time. Search amazon for B001KGSJ74. Also if it is an existing pump, your pump likely already has a contactor or starter on it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed my double float issue that kept failing *by T***A on March 28, 2026* I switched to this style after having many of my type that came with the house fail.
