What’s Wrong With Water Powered Sump Pumps?
Well, a lot actually! Not only are they very limited in their capacity to pump water, they require an expensive backflow preventer in order to protect your plumbing system from contamination. Every plumbing inspector I’ve spoken with wants to see water powered sump pumps banned, and there are groups who are working hard to achieve that goal.
At first it sounds like a great idea… Why worry about electricity, when a water powered pump can function without it? It’s true – the energy that a water powered pump uses to operate comes from the water pressure in your pipes (provided by the municipality). This advantage is far outweighed by the many problems with water powered pumps:
- They waste water, our most valuable natural resource. Fresh water is thrown away (pumped out with the ground water) every time the pump runs.
- They can’t pump water very quickly. An average model pumps only around 8 to 16 gallons per minute (GPM) at 10’ lift. Our Pro Series 2400 backup pumps 40 GPM at 10’ lift, as much as many primary pumps. You don’t want a weak backup to be overwhelmed by ground water during a storm!
- An expensive RPZ backflow preventer is required by code to connect a water powered pump to your domestic water piping. Worse, this device requires annual testing – a never-ending expense.
- Water powered pumps have no means for sounding an alarm, so you won’t know that you have a problem.
Don’t waste your time (or risk your home and what you own) with a water powered pump. They’re more trouble than they seem, and they don’t do a very good job of providing a reliable backup and warning. As I’ve said many times before, you need a good battery backup sump pump system in your basin. If you don’t have a good backup sump pump, you don’t have a sump pump at all!
