The Basement Watchdog Combo Preassembled Primary & Battery Backup Sump Pump System w/Monitoring Controller (CITS-50); Copper-Wound PSC Motor; WiFi-Capable w/Add-on Module

The Basement Watchdog Combo CITS-50 is a reliable sump pump system designed to protect crawl spaces and basements from flooding. It features a ½ horsepower primary pump with a durable cast iron body and a plastic backup pump, providing strong performance with a flow rate up to 73 gallons per minute for the primary and 48 gallons per minute for the backup. This means it can quickly remove water, which is crucial in preventing water damage. The system comes preassembled, making installation straightforward even for those not familiar with sump pumps. One standout feature is its energy-efficient copper-wound motor that helps reduce electricity costs while ensuring long-lasting operation.

The backup pump runs on a 12-volt battery and can provide days of intermittent pumping on a single charge, which is great for power outages or heavy rainstorms. It also includes a built-in monitoring controller that sounds alarms and shows warnings if there’s a problem, helping you stay informed about pump or battery issues. Plus, if you purchase the separate WiFi connect module, you can get real-time alerts on your phone, adding convenience and peace of mind. The pump’s maximum lifting height of 25 feet suits most typical crawl space setups.

One minor downside is that the backup pump is made of plastic, which might not be as durable as cast iron over time, but it’s designed to be reliable in emergencies. This combo system is well suited for homeowners seeking a dependable, easy-to-install sump pump with smart monitoring and a strong backup solution to keep crawl spaces dry.

The Wayne 1/2 HP sump pump with a built-in vertical float switch is a solid choice for homeowners needing reliable water removal from basements or crawl spaces. Its half-horsepower motor provides a strong flow rate of up to 5,100 gallons per hour, effectively handling heavy water buildup during rain or melting snow. It has a maximum lift height of 20 feet, allowing it to push water vertically to a good distance, making it suitable for many typical basement setups.

One of its standout features is the battery backup capability, allowing the pump to run even during power outages, which can be crucial in storms. The backup battery is sold separately, so you’ll need to purchase that to take full advantage of this feature. The pump is made from durable polypropylene, offering decent resistance to wear and corrosion, and it is designed for indoor use only. Installation is user-friendly since the pump comes preassembled and fits in a standard 16-inch or larger sump basin, with no special drilling required. It also operates quietly, which is a bonus for indoor use. The 3-year warranty adds peace of mind regarding its durability and performance.

The pump excels in flow rate and backup readiness but is not intended for outdoor or harsh environments. Because the battery isn’t included, you should factor in that additional cost. Its relatively heavy weight (44 pounds) means it isn’t the easiest to move around, but that’s common for pumps with this power level. This Wayne sump pump is well suited for homeowners looking for a dependable, powerful pump with backup options to protect their basements or crawl spaces from flooding, especially in areas prone to power outages.

Buying Guide for the Best Sump Pumps For Crawl Spaces

Choosing the right sump pump for your crawl space is crucial to prevent water damage and maintain a dry, healthy environment. A sump pump helps to remove accumulated water from the crawl space, protecting your home from potential flooding and moisture-related issues. When selecting a sump pump, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specifications will help you make an informed decision and choose a sump pump that effectively meets your requirements.
Pump TypeThere are two main types of sump pumps: submersible and pedestal. A submersible pump is designed to be placed underwater in the sump pit, making it quieter and less obtrusive. A pedestal pump has a motor that sits above the sump pit, making it easier to access for maintenance but potentially noisier. If your crawl space is prone to frequent flooding, a submersible pump might be a better choice due to its efficiency and quiet operation. For less frequent use or easier maintenance, a pedestal pump could be more suitable.
Horsepower (HP)Horsepower determines the power of the sump pump and its ability to move water. Sump pumps typically range from 1/4 HP to 1 HP. A 1/4 HP pump is suitable for smaller crawl spaces with minimal water intrusion, while a 1/2 HP pump is more versatile and can handle moderate flooding. For larger crawl spaces or areas with significant water problems, a 3/4 HP or 1 HP pump may be necessary. Assess the size of your crawl space and the severity of water issues to determine the appropriate horsepower for your needs.
Flow RateThe flow rate, measured in gallons per hour (GPH), indicates how much water the pump can move in a given time. Higher GPH means the pump can remove water more quickly. For small to medium crawl spaces with occasional water issues, a pump with a flow rate of 2,000 to 3,000 GPH should suffice. For larger spaces or areas with heavy water intrusion, look for a pump with a flow rate of 4,000 GPH or more. Consider the typical water volume in your crawl space to choose a pump with an adequate flow rate.
Head PressureHead pressure, or maximum lift, refers to the height the pump can raise water from the sump pit to the discharge point. This is important if you need to move water vertically over a significant distance. Sump pumps typically have a head pressure range of 10 to 25 feet. For crawl spaces with a short discharge distance, a pump with a lower head pressure will be sufficient. If you need to pump water to a higher elevation or over a longer distance, choose a pump with a higher head pressure to ensure efficient water removal.
Switch TypeSump pumps use different types of switches to activate the pump when water levels rise. The main types are float switches, diaphragm switches, and electronic switches. Float switches are the most common and reliable, using a floating device to trigger the pump. Diaphragm switches activate based on water pressure changes, while electronic switches use sensors to detect water levels. For most crawl spaces, a float switch is a dependable choice. If you prefer a more advanced system, consider a pump with an electronic switch for precise water level detection.
Material and DurabilityThe materials used in the construction of the sump pump affect its durability and longevity. Pumps made from cast iron or stainless steel are more durable and resistant to corrosion, making them ideal for long-term use in wet environments. Thermoplastic pumps are lighter and more affordable but may not last as long. If your crawl space experiences frequent water issues, investing in a durable pump made from high-quality materials is advisable. For occasional use, a thermoplastic pump may be sufficient.
Backup SystemA backup system ensures that your sump pump continues to operate during power outages or pump failures. Battery backup systems are the most common, providing power to the pump when the main power source is unavailable. Water-powered backup systems use the home's water pressure to operate the pump. If your area is prone to power outages or you want extra peace of mind, consider a sump pump with a reliable backup system. This will help protect your crawl space from flooding even during emergencies.
