Sludge Boss Septic Float Switch, Heavy-Duty Sewage Pump Switch for Viscous Liquids and Suspended Solids in Wastewater, Mercury-Free Self-Orienting Tank Float for Septic Pumps to 1/2 HP (20 Ft Cable)

I switched to this style after having many of my type that came with the house fail. 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.

Excellent floats. Good build quality. I've replaced one of my older floats with this and can tell it's made to a higher standard. Instructions are clear cut and can be wired to trigger for fill or for empty. Very happy with this product. Being used on a 220v, 1 hp residential grinder pit.

Built to outlast whatever you're connection it to! Versatile 3 wire connection for turning on something when the liquid gets high or or turning on something when the liquid gets low.

Item is as described. It came with wiring instructions for “filling tank” (normally closed), and “empty tank” (normally open). Float was put into place and operated just like advertised. Very happy with the product.

Excellent switch/float … the next star if it lasts more than 10 years. Look good thx

Replaced failed float switch installed by septic contractor commonly found in big box stores. Quality product and obviously far more durable than what was previously installed.

Nice! A heavy duty float switch at a competitive price. Better than Alderon float switches.

I bought this float because it was supposed to be "heavy duty" and I needed it to switch a 1/2 HP pump. Well it looks heavy duty, but looks are deceiving. The description stated that it could handle 13AMPs. Well after it failed In the ON position, my $1250 pump was nearly ruined because it was running for who knows how long. Luckly, I heard it cavitating and was able to shut it off at the breaker panel. After removing the float I decided to determine why it failed in such a short time period. The answer is that the internal switch used appears to be rated for ONLY 10A!(see photo) Its no wonder it fused internally to the ON position. Buyer should be also aware that the float is mearly a repackaging of another piggy back float switch, and the outter red plastic container is NOT WATER PROOF It was filled with water. This may throw off the float on/off levels you established when installing because the filled red bulb is heavier when filled with water. The red bulb also has an extra weight and styrofoam in it as well, so the styrofoam indicates to me that the design did not expect to be water proof. In conclusion, don't use this for 1/2HP pumps, it may be good enoguh for 10A at most.
