It happens after every major storm. Scores of basements get flooded because there was no electricity for the sump pumps. Homeowners rush out to buy out all the puny backup sump pumps on store shelves. Battery-powered. But after the next big storm, some basements get flooded again – the batteries did not last or the cheap backup pumps failed.
During a severe thunderstorm or a big snowmelt, you don't want to worry about your sump pump (Top 10 reasons why sump pumps fail) and power outages or about the battery on your back-up sump pump. You may be away while your basement floods and mold infestation starts in just a few days. The backup sump pump is your "last line of defense" against basement flooding and thousands of dollars in damages. Its reliability is critical!
For the highest possible reliability, get Hi & Dry Water-Powered Backup Sump Pump! It does not depend on electricity or batteries because it is powered by municipal water. And as long as water is available, they can run infinitely! There is no impeller or motor – there are no rotating parts to break or wear off. No cleaning or maintenance required.
This simple and elegant design uses an old, well-proven principle. Pressurized water pushes through the pump and as it speeds up through a narrow Venturi nozzle, its pressure drops. This creates suction – that’s how they make vacuum in school labs. The emergency sump pump ("ejector") draws water up from the sump pit and pushes all the water out through a discharge pipe.
Location, location, location! They are not submerged inside a filthy sump pit like other back-up sump pumps. Hi & Dry™ pumps are mounted "high and dry" on the ceiling. They draw water from the sump pit by suction just like through a giant soda straw and push it out through a discharge pipe. This unique ceiling-mounted design has inherent advantages:

Hi & Dry pumps have by far the highest pumping rates among water-powered emergency pumps due to their unique "ceiling-mounted" design. Highly efficient – one gallon of city water pumps out about two gallons of sump water.
The pumping rate of all pumps depends on municipal water pressure and the needed lift from the bottom of the sump pit to the discharge. The higher the water pressure, the higher the pump output. But the higher the lift, the lower the pumping rate although it does not decrease dramatically until above 15-ft.

If your primary sump pump has to handle lots of sump water, you will need a larger emergency pump. If interested, you can calculate the actual water inflow into your sump. IMPORTANT! Before selecting your pump model, you must first check that there is sufficient water pressure and flow for the pump size (the "Bucket Test")!
The pump operation is fully automatic – it works whether you are home or away. The backup pump has its own float switch, which activates the pump when water level in the sump pit rises too high – above the level normally allowed by the primary sump pump. This also activates an audible high water alarm to let you know that you have to check the primary sump pump and its power supply. The alarm is a must but other manufacturers do not include it.
SUCTION PIPE – The suction PVC pipe (not included) reaches down to above the bottom of the sump pit and is connected to a check valve (included) just below the pump.
DISCHARGE HOSE – A flexible discharge hose (included) takes the water from the pump through the basement wall to a separate discharge, which is the recommended setup. In case the discharge pipe freezes up, the included pop-up pressure relief valve will spill the water onto the backyard, allowing the backup pump to still operate. If the pump discharge leads to the municipal sewer, leave an air gap of at least 1" to protect against backflow.
Alternatively, the discharge hose can be connected to the main discharge pipe from the primary pump using a T-connector (included). In this case, install the pop-up valve on the main discharge pipe to protect against freeze-up. Make sure that your check valve above the primary pump is in good working order to prevent backflow into the sump pit.
ADJUSTABLE HYDRAULIC FLOAT – This hydraulic (not mechanical) tethered float switch is not dependent on electricity or a battery. Its activation elevation is fully adjustable. It is a sophisticated grapefruit-sized On-Off switch to start or stop the pump that it will not allow water to wastefully "bleed." To help with the limited space inside the sump pit, the minimum needed lift of the float is only about 1". It does not need to fully drop down to its lowest position to turn the pump off. It is connected to the pump by flexible pressurized tubing that is clipped onto the suction pipe. There is an adjustable timer screw on the pump which allows you to adjust how long the pump works after the float drops in each pumping cycle as needed to empty the entire pit (typically set at 20-30 seconds).

Models RB750-EZ and HB1000-PRO come with these pre-assembled accessories:
Also included is a Brass Push-fit Tee to install into an existing water supply pipe. No soldering is needed – just push the pipes in.
The standard Dual Check Valve is a generally accepted backflow prevention device. It contains two internal check valves for redundancy, or a "fail-safe" condition, which allows water to flow in only one direction. Meets ASSE listed #1024, CSA Certified B64.6.
Although you have to buy the PVC suction pipe and water piping locally, our pump kits are quite complete compared to other pumps. Cost Comparison of Accessories with competition.
Models RB750-EZ-V and HB1000-PRO-V are the same except that the backflow preventer is a Dual Check Valve with Vacuum Breaker Vent as approved by the State of Illinois. The standard dual check valve has the added protection of a downstream vented vacuum breaker as required in some jurisdictions. Meets ASSE listed #1012, CSA Certified B64.3. State of Illinois Approval #890-1140(k).
A 10-ft. length of tubing for drainage into the sump is included.
You should first check with your water company on any special requirements for backflow prevention.

Most of the advantages just result naturally from the unique ceiling-mounted design which cannot be matched by the old inside-the-pit design:
"After fearing for my man cave's fate during hurricane Sandy last year I decided I needed a backup sump pump. After much consideration I decided to go with a water powered unit. I purchased the RB-750 and finished installing it this past weekend. Went together great and I was very pleased with the quality of the pump. Also it came with the additional connections which added to the flexibility of the install..." – John V., MD
"Just completed installation of a RB-750 and everything went smoothly. I was pleased to see that everything necessary was included and the instructions were clear. Pump operates normally and works as advertised. Also, I want to thank you for using environmentally friendly packing material..." – Michael B., IL
"I installed the backup sump pump RB-750 myself and I am just a software engineer. It took me about 3.5 hours and it was not difficult at all. The hard part was..." – Brett R., IN
"I moved into a home in July which had a finished basement and I was disclosed that the sump pump system was "newer", but the previous owner did not install a backup system. Well it began with a massive weather system that dumped over 7 inches of rain on Halloween day 2013. All day and up to this point the main sump pump system was working and keeping the basement dry. However around 7pm there was a power flicker and this was the straw which broke the camel's back.. It shut the main sump pump off,..." – Chris R., KY
"...the first time the water was turned on and the water in the sump lifted the float I actually got very worried because it was quiet and I didn't think it worked. Then, I noticed the water going down in the sump..." – Philip B., Ohio

Every water company receives each month several calls from homeowners complaining about "blue water" from their faucets. They and perhaps also their neighbors have been drinking their own toilet tank water which has been colored by toilet bowl cleaner! Instead of a "plumbing code approved" toilet flush valve, they had bought a cheap one.
If a nearby fire hydrant is turned on or a water main breaks, the sudden loss of water pressure may cause "back-siphonage" and draw contaminated water into the potable water system. If your neighbor is using a garden hose to fill a swimming pool or to spray pesticides on his lawn, it may end up in your drinking water during a sudden backflow. And according to an US EPA study, a majority of homes have a water cross-connection to a health hazard.
In spite of regulations and building codes on backflow prevention, many products sold in stores to trusting homeowners do not meet them. Conspicuous among them are the old-school water-pressure pumps located in the sump pit. Their vertical discharge pipe and suction pipe are filled with sump water and they are likely to contaminate drinking water during a sudden loss of water pressure. The homeowners might be exposed to lawsuits for contaminating the city drinking water.
Their manufacturers state that the homeowner must buy a backflow prevention device but it is well hidden in Instructions. Liberty Pumps recommend an RPZ Backflow Prevention Device (Reduced Pressure Zone), which costs more than the pump itself, restricts water flow to the pump, and requires annual certification (about $60–80 each year). However, most plumbers ignore it.
