DIY Pro Sump Pump Kit includes a 18″ x 22″ Structural Foam Basin with Gas Tight Cover, 1 1/2″ Check Valve and Zoellar M-53 1/3HP Submersible Pump.
Sump pumps are the heartbeat of any basement waterproofing project, therefore, a quality pump is your best choice. Cast iron housing is the industry standard — they are heavy, durable and dissipate heat well.
When choosing a pump, consider the switch type. The diaphragm switch tends to be the least reliable. Tethered float switches do work well, until the tethered device comes in contact with the side of the basin leaving it unable to function correctly. Choosing a sump pump with a caged arm float switch is the favorable choice in the basement waterproofing industry, as they are protected from contacting the basin wall.
With most waterproofing systems, a 1/3HP pump is sufficient, if needed, you may upgrade to the ½hp pump to do the job. The standard sump basin measures 18” x 22”. There are basins designed to house up to three pumps, however, only one in five thousand homes have the need for a three pump system. Consider using a quality High Water alarm in lieu of spending a fortune on a multi pump system. Your best protection is an alarm system that will call you when the system fails. This gives you the ability to address the problem as soon as it is necessary.
