Q: I currently have a 1 hp sump with an electronic switch built in. I assume I can not use this item with my current pump, but would have to buy a 1/2 hp regular sump pump. Would I be able to install this switch myself, and how would I go about that. On bad days my pump runs every 10 seconds due to high water springs and deeper than normal basement.
by Norman Toncre from Ohio on July 02, 2016

A: Norman,

The level guard float switch works with pumps up to 1/2HP. This switch is installed on your discharge pipe with zip ties. The install on this is not that hard. The switch can be mounted at whatever height you need it to be for your desired activation level.

If you have any other questions, please feel free to ask.
by Jim, Product Expert
Q: Thanks for replying - the total basin is 23' wide x 29' high but the inflow line is at 16" high so the water would not get higher than 18-19".

Thanks

by Marc Shaw from Oregon on June 30, 2016

A: Marc,

With that size basin, you should absolutely be able to use two different pumps with the level guard switches.

Please let us know if we can help with anything else.
by Jim, Product Expert
Q: Can I use two of these in the same sump pit (ie. one for a main pump and one for a backup) or will they interfere with each other?

Thanks

by Marc from Oregon on June 30, 2016

A: Marc,

What is the size of your basin?

Q: If I have a Zoeller M53 with a vertical float. I have read that the switch is the weak point of this pump so if I wanted to add a level guard to this pump would it work? Additionally would it add a redundancy to the existing float switch or would it complexly replace the float switch?
by Adam from Michigan on February 01, 2015

A: There is no possible way to add an additional switch to your current sump or sewage pump. It would simply not work. Your only option would be to replace the current switch. In the case of the Zoeller model M53 or with any other automatic pump with an integrated float switch, you would need to rig your current pump switch in the "ON" position and insure that it NEVER slips out of that position. Once that is done, you can add the LevelGuard and connect it to your pump via the piggyback connection on the LevelGuard power cord plug.
by Jim, Product Expert
Q: When I installed my LevelGuard, it did not empty all the water from the sump pit right away. The pump ran several times until finally the water level went below the lower switch point line. Is something wrong?
by Francis J from Illinois on July 31, 2014

A: No. When the LevelGuard is first plugged in, it initiates a 'sump calibration routine'. This runs as follows assuming the sump pit is full of water:

Runs pump for 15 seconds, then stops.
Runs pump for 16 seconds, then stops.
Runs pump for 17 seconds, then stops.
This continues, increasing the pumping time in 1 second increments up to 99 seconds or until the bottom sensor is reached.
The purpose of this routine is to protect the equipment from running continuously in the event of a failure of the LevelGuard to detect a change of state by the lower sensor. This might occur if buildup of foreign material on the LevelGuard occurs or an object such as a sock falls into the pit and clings/covers LevelGuard's sensor area.
by Jim, Product Expert
Q: The side of my sump pit gets covered with a scum build up that can get up to two inches thick. Will this cause a problem with this field sensing technology?
by Kurtis Y from Iowa on July 15, 2014

A: Thank you for your interest in Sump Pumps Direct. I brought your concerns up with the folks at LevelGuard and received the following response.

Yes, build up like that can definitely prevent activation of the LevelGuard sensors. This could particularly be of concern if the sump was filling and the LG fails to sense the rise in water level. Heavy build up of material on the LG surface can also cause false activation of the sensors but this is less of a problem due to the pump run-on prevention feature built into the software.
Regarding their "Peanut Butter Test" Video that we show on our site:
While this seems like a straight forward question the answer is highly dependent upon what the build-up material consists of. For a non-porous, non conductive material such as peanut butter the thickness would be 4 to 5 mm. For a material that soaks up water as it sits it would be considerably lower.


In addition, all manufacturers do recommend that you inspect your pumps, switches, batteries (if applicaple) and basins every 3-6 months to insure that the pumps and switches are operating correctly and there is no debris that might impede their operation. In addition, batteries should be checked for acid levels and terminals should be clean.
If you have additional questions, please let me know.

Q: How does the level guard switch work
by Gary R from Ohio on May 03, 2014

A: Thank you for your interest in Sump Pumps Direct. The LevelGuard switch works based on Field Effect sensing technology that was developed by TouchSensors, Inc out of Wheaton, IL.
Field-Effect sensors are digital, solid-state electronic devices that can detect conductive materials such as water or the human touch. The sensor’s cell design uses an integrated circuit (IC) that switches its output state when the conductive target is sensed. A Field-Effect cell is comprised of three main elements, the IC, a unique sensing electrode geometry, and two tuning resistors. Moreover, Field-Effect requires no moving parts, floats, software, or any other mechanism to operate.
When 5 VDC is supplied to the sensor, a low power, invisible field is created. The field emanates directly through any protective dielectric barrier such as plastic or glass that may surround or cover the sensor. When a conductive object or material enters the field, the sensor detects the change and indicates an event has occurred with a corresponding output signal. The input stimulus to the field is typically water in most liquid level sensing applications, as is the case in TouchSensor’s™ LevelGuard Home Sump Pump Control product line.
by Jim, Product Expert
Q: Can the Level Guard be used with any system?
by Jason from Minnesota on February 12, 2014

A: The LevelGuard Z24800A1Z - Electronic Sump Pump Switch, is designed for sump pump only, rated up to 1/2 HP (12A Continuous - 30A Fused or Surge).

Really Like This Switch, No Moving Parts
I don't have a lot of room in our sump pump crock, this switch is perfect for what I need. It doesn't have a float to get caught or hung up, and takes up very little room. It's also very simple to adjust.
Pros: Reliable, I'd Buy It Again, Easy To Use, High Quality

Level Guard Is A No Brainer!
After my sump float failed and basement flooded, I was looking for a switch without mechanical components and failures. The Level Guard system was the perfect solution! Solid state electronics sense water level and turns on pump, then shuts it down. It was easier to install than a float. I wish I would have known about this before the flood. I plan to replace the floats in my lift station with LevelGuard.

Easy To Install And Has Been Running Great
I have a 1/2 horse sump pump that runs every 30 min or so, all year long. I was very concerned about the float going bad or getting jammed up, so when I found this product I was a little excited to see it has no moving parts. The product was very easy to install and Its a little early to say the product is great but Sump Pump Direct was. I am looking at getting an other back up sump pump system and for sure will be getting it form them.
Pros: Reliable, I'd Buy It Again, Quiet

Easy Replacement For A Mechanical Float Switch
I ordered this on the recommendation of one of Sump Pump Direct's technical folks (I had called about the warranty on my failed mechanical switch). At just $30 or so more than the mechanical float switch, it carries a five year warranty and is promised to be more reliable. One feature I like is its switching off the pump after a maximum 60 seconds after the low level limit is reached. This prevents my pump from running dry, which was what I awoke to the morning my mechanical switch failed. ... more

Would Recommend With Qualifications
The switch works as advertised and designed. It is well made and an interesting solid-state design. I got it primarily because of the solid-state design. There are two things to bring to attention. First there is a calibration process described briefly in the manual. If the pump cycle is regular this process in not an issue. If the pump cycle is very irregular as mine is the calibration process can take a long time. Unplugging/re-plugging the electric cord re-initiates the calibration process. more
Pros: Easy To Use, Quiet, High Quality, Solid-state design
Cons: Fixed ON/OFF Range
