Our most reliable sump pump system, the TripleSafe™ Sump Pump System, provides three levels of protection for your basement and your peace of mind.

For normal functioning, the TripleSafe™ has a powerful, cast-iron Zoeller® ⅓ horsepower sump pump set at the lowest level. For heavy volumes of water or in case of primary pump failure, a second, more powerful Zoeller® ½ hp pump set a bit higher in the liner will take over.

In case of a power outage, our UltraSump® battery backup sump pump, set at the highest level, will pump 11,500 gallons or more on a fully charged battery!

Hi There, I would like to have your input on the horizontal crack found in the unfinished basement foundation for this house. I am in the process of buying this house, and during inspection, a horizontal crack in the basement foundation is pointed out. Please find the below image and would appreciate if you could let me know how serious this is and estimated range cost for repair as this would help my decision on completing the purchase or not moving forward.

We have a pair of existing sumps with two check valves merging into a single outlet pipe. I replaced the main sump a couple years ago (proactive, but getting older) and have noticed we are not getting the run time out of the backup pump when the power is out that we require. I have two deep cycle batteries (only one connected at a time) and each one drains in 4-6hrs. Since one of the batteries has only seen light use and is less than 3 years old. I'm assuming the problem is an aging pump because my neighbour gets 5+ days on a single charge from a similarly spec'd battery. I'm interested in the following changes: - Replacement of the backup pump and BMS - Adding stop valves above the check valves to simplify maintenance

Occasional small amount of water in the basement (2-3 times in 6 yrs). In the process of finishing the basement and would like it fixed, so no future problems would arise.

Hi there, I have a number of cracks in my basement foundation and one going up a foundation wall that I would like to have checked, possibly fixed. I can tell based on other areas of the house that there is a lot of shifting/settling happening and want to ensure there are no issues with my foundation. Thanks

Hello. Just bought a radon detector and it is reading about 8.04 pCi/l in the basement. I am testing in other areas of the basement but would like you guys to come in and give me a more accurate reading and possible mitigation method/estimate. Appreciate you getting back to me by email please.
