Answer: 
The float switch is a small sealed reed-valve (magnetic) unit that attaches to an L-shaped metal bracket about 4 inches long. The manufacturer supplies cable zip ties to attach the float to the vertical drain pipe. The float should be positioned about 10-14 inches above the sump floor, and more importantly, in a position where the backup pump will turn on once the water level is 1 to 2 inches above where Read More
The float switch is a small sealed reed-valve (magnetic) unit that attaches to an L-shaped metal bracket about 4 inches long. The manufacturer supplies cable zip ties to attach the float to the vertical drain pipe. The float should be positioned about 10-14 inches above the sump floor, and more importantly, in a position where the backup pump will turn on once the water level is 1 to 2 inches above where your primary pump would normally turn on.
When the backup pump is actuated by it's float switch, it runs for a timed 20-25 seconds to empty the sump. This is because the float switch travel is only about 1 -2 inches. I have found this setup works very well, it was well thought out by the engineers designing the system. I attached the float switch to the drain pipe using a normal hose clamp, it is sturdier than the zip ties in my opinion. Read Less

Answer: 
There are zip ties included in the system, and you just zip tie the float with the L bracket onto the discharge pipe. (the drain pipe)

Answer: 
Yes, this pump will run if the A/C power (to charge the battery for this pump) is off or on. This pump always runs off of the 12-volt battery. In other words, if your main pump fails (for any reason) but power is still on, this pump will run. If the power is out, this pump will run as well. It is designed to run with A/C power off or on.
Also, this pump can run if your main pump can not keep up with the Read More

In other words, if your main pump fails (for any reason) but power is still on, this pump will run. If the power is out, this pump will run as well. It is designed to run with A/C power off or on.
Also, this pump can run if your main pump can not keep up with the inflow of water. What you do is set the float for the backup pump to turn on when the water is 1-2 inches above where your main pump would normally turn on. So, it is an assist pump for hi flow situations and also a backup if your main pump fails for any reason, including (but not limited to) power loss.
The only reason this pump would not run is when the 12-volt storage battery is depleted and/or reached its end-of-life. Read Less

Answer: 
I installed the entire pump at the bottom of my sump next to the existing 120v standard pump. You will probably have enough room to do the same; it may require a little push of the existing piping to place one pump next to the other.

The difficulty with installation is the PVC connection to the existing drain line of your original system. This will be the rate limiting step no matter which system you buy. I live in an area where we don't see regular heavy rains so the pump hasn't fired yet. It does test well so I feel confident that if the need arises, it will do the trick.

Rated 3 out of 5 by from Some issues encountered after 10/10/2010 We have had this unit since 2010 and we recently had an alarm which was sounding on the system. I then took out the marine battery and brought it to an auto parts store to fin out that it was not holding a charge (Not to bad for 4-years on a battery). Anyways, After replacing the battery, I found that the charger was not working correctly as it kept alerting after the battery replacement which should only happen for about 30-seconds and then result in a reset. This however did not happen and I let the thing whine for about 5 hours. The next day I took the control unit apart and found the source of the issue which I think is the same thing that a lot of people have been giving it negative reviews for. It seems that when the board was constructed, they used a 470uf Electrolytic Capacitor @ 35v. This component was built in the same batch as some of the other bad capacitors out there so in turn it ended up boiling and eventually bursting or doming over. I was able to pickup a new 470uf@35v Cap from my local electronics store and with some simple solder work, I was able to de-soldier the old bad CAP and replace it with the new one. The system has since been working fine ever since. It seems they should have went with a better sealed capacitor and not a standard Electrolytic.

Rated 4 out of 5 by from Instantly adds peace of mind Installation was super easy once I had all the right components. Instructions on how to install the unit were adequate but knowing what components are required to join the pump to the plumbing/pipes were lacking. FYI... When pump is in use, there is water that spits out the base of the pump. If you mount the switch too low, the pump will remove all the water and spray water onto the side and splash out of the sump. When purchasing, keep in mind that Home Depot (Canada) does not sell the battery recommended for this unit. Comparable batteries are very expensive (+$200) or more for a good one. I purchased a 90Amp/h (45 to 70 recommended) Sealed AGM Marine battery which should give me about 10+ hours of use.

Rated 5 out of 5 by from LET IT RAIN, LET IT RAIN, LET IT RAIN. Installed and tested several times and backup system works like a charm. I feel a lot more secure that I have this system. Now after 15 years I feel I can finish my basement and not get flooded again.

Rated 1 out of 5 by from mr. wayne back up sump will need a back up I bought this pump to replace the back up that had been in place for 3 years and had worked well the few times it was needed. Went all through the set up in a cramped and not all that pleasant hole only to find on testing that the pump leaks around the gasket when activated. Since it is working better than nothing and the inconvenience of redoing the whole job and trying to go through the hassle of returning the pump to a store seems like a huge hassle I guess I will live temporarily with this poorly made and obviously not tested product.
