        Answer This Question

        A:  Derp- It does vary by personal choice. A vertical switch is fixed and cannot be adjusted. However, it may run more times as the basin wouldn't fill up as much before starting. A tethered switch can be adjusted to allow basin to fill with more water before starting. However, tethered switches also have a tendency to get caught on something which could affect how pump starts.

          sump with vertical switch
          Pros: - vertical switch which is less likely to be obstructed by the side of the crock - switch is hardwired into the pump circuit, not an extra cord coming up the to the receptacle - discharge is 1.5" with a bushing for 1.25" - intake above impeller so hard debris should settle to the bottom of the crock and not get sucked in to ruin the pump - rust free aluminum motor housing Cons: - plastic base which seems thin and unlikely to withstand any impact, be careful during installation - plastic discharge threads, use caution when tightening the discharge pipe - intake is above the impeller so there will always be at least that much water in the bottom of the crock - plastic impeller could break if debris is sucked into the pump

          Aluminum Sump Pump
          This K2 - 1/3 HP Aluminum Sump Pump with Vertical Float Switch functions just as described. I use this one under my house in a crawl space because it performs well in narrow sump pits with diameters of 10” or larger. I have a narrow holding area that is about the size of a large bucket. Constructed of non-corrosive reinforced thermoplastic material makes it ideal to leave in a place where it requires little or no monitoring. The pump moves water up to 3450 GPH at 0 ft. with a maximum lift of 26 ft. What I like is the fully adjustable automatic float switch that accurately turns the pump on and off as needed. Energy-efficient PSC oil-filled motor and the Top suctions design filters debris and handles up to 1/4 in. Solids.

          Long lasting - Aluminum Sump Pump
          This Sump Pump by K2 is a great product with nice features. First it is made out Aluminum that resists corrosion. The vertical switch is works freely and is less likely to get caught on the sides of sump well. The epoxy coated aluminum housing and oil filled motor provide for longer pump life. This pump has a top suction intake to limit debris that might be present. This pump is strong...pumping capacity is 3450 GPH and has a maximum lift of 26 feet.

          Lightweight Pump Does The Job!
          Let me first start off by saying this sump pump is much lighter than my previous Ridgid sump pump which was made of stainless steel motor housing and cast iron base. This K2 pump has an aluminum motor housing, but the base is plastic. I do prefer the cast iron over the plastic, but as long as it holds up to father time like my Ridgid (8yrs) then I’m ok with that. I do like the fact that the inlet was built on top of the base and not underneath which will minimize bottom debris collection. I also prefer the vertical float switch pumps like this one has over the in-direct floats as a personal preference. Overall this lightweight pump works just as good as my Ridgid so far. My only concern is the plastic base, but only time will tell.

          Very well design float switch, nice pump
          So far I'm impressed with this pump. We have a gravity septic system that requires the final (clean) water to be pumped 10 feet to the surface so it can evaporate or be soaked up by vegetation. We swapped the pumps out as a preventative measure (the old one was almost 6 years old) and so far this one has been humming along without incident. I am slightly concerned that the housing is a thin aluminum and not the heavy cast iron I am used to, however I suppose aluminum dissipates heat better and it was much easier to raise and lower into the pit. I love how this pump has a plastic "lift" attached to the base, it provides just a little extra room for debris to settle out of the water and keep the pump impellers free. Probably the best thing about this pump though is the float. It's a vertical float and feels incredibly well designed and solid. Rising water causes the plastic bubble to lift, which hits a nut and pushes the shaft up. When the shaft makes trips the switch inside you can really feel how rugged the switch is. The vertical float takes up much less room in the tank than the old "toilet bowl" style floats. The pipe connections were a breeze, it's all your standard pipe threading and PVC sizes. I was able to screw the pipe from the old pump directly into this one and reuse the entire assembly. All around a very well built and designed pump. Time will tell on that aluminum housing but I have high hopes.

          1/3 HP Sump Pump
          This 1/3 HP Aluminum Sump Pump features an adjustable vertical float switch. With its aluminum body in combination with its thermoplastic parts, this sump pump is designed to last. This pump is equipped with an energy efficient PSC motor and the vertical switch it uses has been tested at 1 million cycles. The switch is very important and is the number 1 cause of failures of a sump pump. This pump has a maximum lift of 26 feet. Maximum discharge of 3450 GPH is possible with little lift. The higher the lift needed reduces the GPH that the pump can do. Pump has a 10 foot power cord. This is a great sump pump, and for the price, it is a bargain.

          Great size and design
          I would give this five stars if it were a cast iron bottom, but this is a perfect design for my needs. I has a single cord, can fit into a five gallon bucket, fits two sizes of PVC pipe and the float is a fixed switch rather than floating from a cable. I use these in my window wells, as they always flood in the rainy season. And being subjected to harsher outdoor climates and dirty water, I bury them in 5 gallon buckets (which I drill weep holes into) in the bottom of the wells. That is the reason I prefer cast iron, but the aluminum and plastic should hold up just as well. This model has plenty of lift for the plumbing distance and the single power cable makes it easier to run power to the outdoor location. The motor is also reasonably quiet and probably can't be heard from another room.

          Compact 1/3 HP pump
          My sump stays dry most of the time, but during very heavy rain downpours it can fill up - and quickly. In 30 years at this house I've flooded twice. The first time was during a NorEaster when the power went out during a deluge - after that incident I purchased a generator. The 2nd time was a tropical storm, when the generator worked but the pump died mid-storm. Since that time I've always kept a spare pump at the ready, just in case. This K2 pump seems perfect for my spare - it is compact, it's fairly lightweight, and my quick test run demonstrated that it'll handle all but the most catastrophic deluges. I nit-picked and gave it 4 stars instead of 5 because there does not seem to be a way to adjust the float engagement point... but normally that should not be an issue.

          Good construction
          I received the K2 1/3 hp aluminum sump pump in good condition. The unit appears to be well-made. It is made in China. This type of sump pump has a vertical sliding float which activates a switch at the top of it’s travel. The pump stays activated as the water level drops until the float hits the bottom of it’s travel. The top switch has a protective rubber boot. In testing, I found the switch and pump to be functional, and it did not fail in my limited experience with it. I have not had a chance to install this pump since all my sumps are currently working. I cannot speak to longevity or durability. The pump is CSA approved. Given the apparent build quality, I expect that once installed this pump will provide good service for years. The sump pump has a one year warranty.
