Water-jet sump pumps or "sump-jets" as they are sometimes called, can be a reliable back-up to your standard sump pump in the event of a power outage or pump failure during extreme weather conditions.
A small volume of municipal water at high pressure is used to spin the pump and eject water from your building sump, typically at about 300 to 500 gallons per hour depending upon the pumping height and distance.
Small water-powered sump pumps suitable for the average home vary in price, from about $250 to $400 or more, and are available at most hardware stores, building centres and big box stores.
The discharge pipe for a water-powered sump pump is plumbed in parallel with your pre-existing sump pump, and the water supply to power the pump comes from your municipal water main.
The installation of a reliable back-up sump pump system can provide discounted insurance premiums with many companies. Talk to your insurance broker today.
Plumbing codes vary from place to place, and you should first check if this kind of pump is permitted in your municipality.
