Customer Questions & Answers

for the float switch, what is the maximum depth of liquid to cause the pump to come on? I am building a tank and I need to know how deep to build it.

This information is not listed in the product specifications.
Asked by: Harold
I think you mean what is the minimum depth to float the switch. The float has its own cable and comes set for 14 inches or so. But with the flexibility of the cable the float can be repositioned lower if necessary. The deciding factor is the amount of room around the pump to allow for free movement of the float.

My float switch has a crack in the float, can I change out the piggyback mechanical float switch with float and if so where can I order it? I discovered this while trying to chase down why my GFI was continuously tripping. Pump works without tripping GFI only when the piggyback is plugged in does it trip. My original purchase was Model 9S SMPX-LG. If I can't change out the switch is this one a suitable replacement pump for the one I have.
Asked by: budgetDYI
The float switch on that comes with this pump and in fact the vast majority of pumps is not proprietary. Little Giant does not manufacture float switches they source them from others. So you can use use any float switch that is appropriate for the pump you are using. You want to make sure the float switch you choose is for the correct voltage and amperage for your pump. Also that it is set the the correct angle. Most floats are designed so that the pump receives power when the float, floats up to 90 degrees of where it was originally hanging. I mention this because I have run into floats set for different angles. But the majority are 90 degree. Installing and adjusting the new float so that the pump comes on and off when you want it to is critical to the long term operation of the pump.

The picture in the installation instructions show the tether to the pump adjusted so that the pump would not switch off until much of the pump was above the water level. Since pumps last much longer being cooled by being under the water, wouldn't it be better to secure the tether so the pump would never run above the water line, especially in a large capacity tank?
Asked by: Rocky
Great call. You are absolutely correct. In fact in most of my installations, when possible, I install the float or floats in some cases so that the pumps are always under water. Meaning if the chamber is large enough, I only remove the water that is above the pumps so that they are always submerged. Yes this does help in cooling but the real reason is corrosion. By having them submerged they never dry out. Repeating cycles of wet and dry result in more rust. For the most part over heating becomes an issue when the floats get hung up and the pumps run continuously for days. Eventually the cooling oil in the pump super heats and runs out of the pump and it fails. Proper and thoughtful placement and installation of floats is the biggest factor in pump longevity.

Difference between 9S-CIA-RSF and 9SN-CIA-RF

My simplex basin calls for a 9S-CIA-RSF pump assembly, you sell a 9SN-CIA-RF Can you tell me the difference? Thanks!
Asked by: Tony
There has been a numbering change to indicate the change to a split capacitor motor which is more energy efficient. Assuming the voltage and phase are correct this should be a good replacement.

9SN-CIA-RF 4/10 HP Submersible Sewage Pump with Piggyback Mechanical Float Switch is rated 4.3 out of 5 by 6.
Rated 5 out of 5 by from Pump has been in septic tank for over 1 month,... Pump has been in septic tank for over 1 month, absolutely no problems what so ever! Much quieter than the original. There are only 2 residents in the house so the pump does not see extensive use, but it has been flawless so far. I highly recommend this pump.

Rated 5 out of 5 by from Great replacement pump This is a replacement for an 18 year old Little Giant pump that finally died. Installation was a breeze. Had the old one out and the new one installed in less than two hours. If this pump last half as long as the original it will be a great value.

Rated 5 out of 5 by from Easy purchase, great product, free shipping replaced a failed liberty pump (less than 3 years old). needed a reducer but other than that the pump went right in. pumped off the effluent in minutes much better than what I had before. very sturdy pump, I hope it lasts longer than the liberty. Not fun messing with the septic. the specs on home depot's site are off. they are showing GPH and the rating is actually GPM. That makes a big difference. The manufacture has detailed specs available. The starting and running amps were important to me (low) because I didn't want to have to change anything on the electrical to the house. The old pump was on a 15 amp circuit. BTW this is a continuous duty pump. We had 2 months of rain in FL (water table was way up) and I think that pressure burnt the old pump before it should have.

Rated 5 out of 5 by from Good price great delivery The new pump replaced the old model perfectly. No adjustments for outlets or heights were necessary. I took the old one out and dropped the new one in.
