Customer Questions & Answers

Can I use this with a 3/4 hp pump?

Asked by: microangelo
Hello microangelo, I’m Chris from the Home Depot’s how-to Community. Thank you for your question. Maybe. If your current sump pump has 2 power cords, then you can attach this switch to the pump top and not use the cord from your current switch. All is well. If your pump has only one cord, that means that your existing float switch has its electrical contact inside the top of the pump housing and cannot be bypassed. In that case this switch will not work for you. I hope this helps, Chris. .

Rated 5 out of 5 by from Worked as expected. It has an 810' long power... Worked as expected. It has an 810' long power cord which was nice. Most other units only have 8'.

Rated 5 out of 5 by from A good quick fix I have an expensive Flotec sump pump with the vertical on/shutoff switch similar to the Model # FPSC4550A. It's 3/4 horsepower and does a really great job. The problems is that the shutoff switch just doesn't work all the time, and the pump will run continuously. I had a Rigid pump that had the same problem and it burned itself up. Even though this is a completely different type of switch, it solved the problem of a pump that will not shut off. You just plug it in between the pump's cord and the electrical outlet. Run the float into the sump, attach it to something, and adjust it so that it shuts the power down before the water reaches the level where nothing is being pumped. Much cheaper than replacing a good pump that just doesn't know when to quit. It also make it quieter because even when the original switch was working, it would be loudly sucking air at the end of the cycle. I could buy 4 or 5 of these for the price that I paid for the pump.

Rated 4 out of 5 by from Easy to Replace, But Is There a Quality Concern? Approx 2 years ago, I replaced my sump pump with a FLOTEC FP0S3200A-09, which came out of the box with a FP18-15BD Float Switch attached. My sump runs frequently (18-24 times per day). The pump continues to run perfectly, however, after only 2 years, the Float Switch failed and would not turn the pump off. I purchased a replacement FP18-15BD, but now know I need to keep an eye on it. The hardest part about making the replacement was removing the old corroded 1/4" screw that holds the cord retaining clamp to the top of the pump. If the first switch would have lasted longer, I'm not sure there would have been enough screw head left to be able to remove it (easily). Overall, replacing the Float Switch was quite easy and quick (and about $90 cheaper than replacing the entire sump. As stated earlier, my concern is Quality, if the first switch only lasted 2 years.

Rated 5 out of 5 by from on the switchs to those of you who had failures with this switch, i know from what i have read on the reviews that there are different styles of pumps used. this float does not have to be hooked up by the book, or how the original was hooked up. the least you can get the pump to run, the less wear you will have on the pump. i worked in a steel mill in the utilities section and we used a lot of these types of pumps and switches, check to make sure your switch is not being exposed to any chemicals in the water that could cause the rubber sealing the switch to leak, if need be run a bead of silicone sealant around the chord to the switch, this would be an added protection to the switch. then again replaceing this this switch again is still cheaper than going for a new pump, like i said in my rewiew- my pump is all cast iron including the impeller and will last longer than my house, also make sure if your sump has the horsepower to pump the sump out with out having to run all the time and to use a check valve that is in line if you can. this will prevent the discharge from running back into your sump. i have to pump from the sump to about 18 feet, with the inline check valve in keeps the pump from running all the time. thus a less amount of fluid in my sump well,

Rated 5 out of 5 by from So Far, So Good :) This is a great replacement Float Switch for my sump pump. Old one gave out after only 2 years. Direct replacement, straight forward installation in less than 5 minutes using only a #2 Phillips Screwdriver.

Rated 4 out of 5 by from Great purchase I had a sump pump failure and it was due to the floating switch. After looking around i found that Home Depot carries this unit so i purchased it and after a couple of hours, the sump pump is up and running. The price was about half as much as from the contractor and it was convenience since i am close to Home Depot. Thanks goodness for Home Depot. It makes DIY projects easy and convenience.

Rated 5 out of 5 by from Easy Fix for Sump Pump that Wouldn't Stop Pumping! I came home one evening and heard a very loud noise coming from the sump pump. It was continuing to pump with little water in the pit. My husband ,who is the handy one, was out of the country . It was raining, so I was envisioning a Saturday evening call to the plumber and $$$. My teenage son started googling. We determined it must be the sump pump switch because the float was moving up and down unobstructed yet it didn't turn off. I still didn't think I wanted to fix a "switch". That sounded like opening up the unit and doing something electrical. I came here to the Home Depot website and found this product that looks like the one we have. Thanks to others for the helpful reviews and to Home Depot for telling me which store had it in stock and exactly where in the store. I was in and out in 10 minutes. It is extremely easy to install. Ran the sump pump to remove the water in the pit. Unplugged it and cut the plastic tie that held the old float against the pump and removed it. Put the new float in the same position as the old and attached it with the plastic tie included in the kit. Plug the float into the outlet, then the sump pump into the float plug and watch to see that it works. Done.
