Z2480AA1Z Solid State Sump Pump Switch

The switch itself is great (it has worked flawlessly so far), but I also want to call out the customer service and how amazing they are.When I initially received the switch, I noticed that it looked used. No problem, these things happen. I reached out to the seller (TouchSensor Technologies) and a rep named Thresher replied promptly. The rep apologized, and asked for some pictures of the switch. After reviewing them, they told me that something obviously happened and made it clear they intended to make it right. To make up for it, they sent me another new switch, and overnighted it so I would receive it the very next day. And yes, the switch I received was brand new.I completely understand that mistakes happen, but it's how these mistakes are handled that ultimately matters. And from that perspective TouchSensor was absolutely great to work with. Thank you again Thresher!

Purchased this unit for level control in a custom sized condensate tank for my furnace. I wanted to maximize the high to low range for the given tank and found the normal operating range of typical floats was excessive. The other issue with floats is to meet california guide specs you cannot have mercury switches hence most float manufactures have converted to the mechanical type which have a limited cycle life. Mercury float switches are available online but not in most big box stores. This unit has about a 8 inch normal operating range which worked perfectly for my application. I selected this as it is totally solid state but was concerned about a few reviews that mention that the max pumping time is limited to 60 seconds. You can only get that info from the manufactures website. This is true and given my pump and piping size the high to low pump time was 90 seconds. To mitigate the issue I changed the pump output line size from 1/2" to 3/4", and that put the pumping time from high to low at 45 seconds, well within the limit of 60 seconds. It has operated OK so far. My furnace puts out about 12 gals a day of condensate so it will cycle about three time a day.Update after one year: Still working good!

I have bought my second one of these, since my house has two sump pumps. The first one has seen heavy use for about a year and working great. Got the second to replace a failing float switch in my second sump. These are not cheap but I trust they will work a long time based on technology and design quality. I don't write many reviews but feel it's needed to offset the few negative reviews. It seems in some cases these didn't fit the use case of a residential sump pit, or they got a rare quality control issue. A few top online sump pump suppliers sell these as part of high dollar kits and I understand why. For $100 I believe it's a 5-10 year solution vs 3-5 for other float styles. I paired them with Zoeler pumps without built in switches since that's a common failure point of those, and one of mine failed at 10 years. I replaced a Hydromatic that lasted 15 years and looked like it was in a shipwreck from 100 years ago when it died (rust ball) but was still pumping. Those are the top end in my book, but for $400 for that I went with a similar Zoeler for 3/4 the price since I needed two.

I had to replace my pressure style piggyback switch which was almost as costly with this new sensor. As an electrician, I picked this particular switch because it had a higher amperage rating and was for sewer application. I am using this though only for my grey water sump. I figured that since I have a half horse effluent pump as a sump, this would be strong enough to handle the load, and not fail due to getting dirty. I was pleasantly surprised to watch it work for the first time. My original pressure switch would allow the pump to cavitate when it fully emptied the pit. This switch shuts off just before it completely empties, thus preventing that harm to pump and extra noise. The other main reason for going with this style switch is that my pressure style switch started to fail by sticking on like the last one I replaced. Hopefully this new switch will add more lifetime to my pump with its new cycling habits. I am impressed so far. I like the no moving parts aspect the best.

Decided to upgrade to the sensor style after trying a few different float styles over the years. Between floats catching on the way up or down and either burning out the pump or flooding the basement I tried a better float system. After dealing with mechanical failures with better floats, I decided to perform my due diligence and start researching a better system. At first I was a 'bit turned away by the cost of these sensor systems, but you really have to ask yourself, what is $100 or so for something that is going to save hundreds of dollars worth of pump, or thousands of dollars worth of flooded basement? So far, this sensor system has performed flawlessly. It fits better in the pit, it turns on and off at better points (adjusts automatically after a few cycles!), running the pump through less cycles, not running the water too low so as to run the pump dry and not letting it get too high in the pit. All the research I have done (consumer and contractor reviews) shows that these sensor systems last much longer than the float systems, and are the way to go unless you like have a swimming pool on your bottom floor.
