Water-Powered Backup Sump Pumps for the highest reliability!Unbeatable reliability and performanceReliability of the primary sump pump is very important but it is absolutely critical for the backup sump pump, which is the "last line of defense" against basement flooding. No electricity or batteries needed. During a heavy rainstorm or snow melt, you do not have to worry about a power outage or sump pump failure, or about batteries on a battery back-up sump pump. When called upon, the water-powered backup pump can run infinitely, as long as municipal water is available – not limited by a battery charge. This pump requires no cleaning or maintenance. There is no impeller or motor – no rotating or moving parts to break or wear off. It is constructed of heavy duty, corrosion-resistant materials (Schedule 80 polypropylene) for practically unlimited longevity. How a water-powered pump works
Backup sump pump operationThe 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 simultaneously activates an audible alarm (needs a 9V battery) to let you know that it is operating and that there is something wrong with the primary pump or the power supply. The hydraulic (not mechanical) tethered float switch is not dependent on electricity or a battery. Its activation height is fully adjustable. It is connected to the pump by flexible pressurized tubing, which is clipped on to the suction pipe. To help with the limited space inside sump pits, the minimum needed lift of the grapefruit-sized float is only about 1.5–2 inches. It does not need to drop down to a vertical position. There is an adjustable timer on the pump, which sets how long the pump works in each pumping cycle as needed to empty the sump pit (typically set at 20-30 seconds). The best value among water-powered back-up sump pumps!Location, Location, Location! What makes our pumps particularly unique is their location outside the sump pit:
These are the most reliable pumps on the market – backed up with a 3-Year Manufacturer's Warranty, the longest in the industry (and longer than the typical life of some pumps). How to choose the right pump sizeThe volume of water drawn by the ejector depends on the city water pressure. The higher the water pressure, the higher the pumping rate. Pumping rates in GPH (gallons per hour) for all models based on a 10-ft lift:
The higher the needed "lift" from the bottom of the sump pit, the lower the pumping rate. But up to a 15-ft. lift, it does not decrease dramatically. Choose your installation optionThe standard classic set-up has its own suction pipe from the sump pit and its own discharge hose, which can lead to a separate discharge or be connected to the primary pump discharge pipe. The suction pipe is straight and its stainless steel suction screen protects the pump against debris. A separate discharge avoids the risk of a clogged or frozen primary discharge pipe but in case the backup discharge pipe freezes up too, the included pop-up pressure relief valve will spill water onto the backyard, allowing the backup pump to operate. If the discharge hose is connected to the main discharge pipe (using a Y-connection), install the pop-up valve on the main piper and make absolutely sure that the primary check valve is in good working order. The Easy-Install Kit greatly shortens the installation time – by about half, according to experienced plumbers. It uses the already existing discharge pipe from the main sump pump for suction and discharge. It draws water through the primary pump, which modestly increases the pressure drop but it is great for tight pits. The backup pump and the installation kit can be quickly assembled on a table and then, inserted into the existing discharge pipe. This option is available for all our models and there is no price extra.
How the Easy-Install Kit worksWhen the primary sump pump operates, the discharge water flows through the discharge piping as usual. It cannot force its way through the backup pump because the loop includes a check valve.
When the primary pump is turned back on, the float of the backup pump stays down and the backup pump is on standby again. A complete kit for do-it-yourself installationThe illustrated pump and accessories kit is for the classic set-up with separate suction and discharge pipes. (The Easy-Install Kit is just as complete but some accessories are different.)
The pump is mounted on the ceiling joist above the sump pump. The flexible 6-ft. discharge hose allows for various arrangements for taking it through the exterior wall. Alternatively, the discharge hose can be "teed" into the primary pump discharge. The included high water alarm provides an audible warning that the backup pump is working and there is something wrong with the power supply or the primary pump. You will need to purchase locally the needed copper, PEX, PVC or CPVC piping, as approved in your area and fittings to "tee" into the municipal water supply pipe and bring water to the pump, as well as the PVC suction pipe. As an example, check out an actual installation of the RB-750 pump by a homeowner - layout, connections, and discharge. Do-It-Yourself "Push-On" Plumbing Kit
These state-of-the-art push-on fittings make connecting the backup pump to your 3/4" water service quick and easy. Just push a tube into the fitting until it reaches a positive "bottom" and it is sealed! Fast and easy secure connections. No frustrating leaks. If needed, you can turn the fittings to line them up properly. Each connection can be disassembled if needed. The kit includes:
You need to buy straight lengths of 3/4" tubing – PEX or CPVC or copper piping. Using flexible piping, PEX or copper, reduces the number of needed elbows. Feel free to mix copper or PEX tubing. PEX has flexibility and a low price. One push-on elbow is included and you can order extra elbows if needed. The flexible stainless steel tube means that "close is good enough" when bringing in the water piping – it greatly saves on elbows and time. There is no extra shipping cost when ordered with the pump. Unlike store-sold products, these fittings are the latest design – all-metal (brass), without plastic parts for maximum durability. Backflow prevention is about safe waterEvery 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 hydrant is turned on or a water main breaks, the sudden loss of water pressure may cause "backsiphonage" and draw pollutants or contaminants into the potable water distribution. If your neighbor is using his garden hose to fill a swimming pool, or to spray pesticides on his lawn, or to flush his radiator, the contaminants may end up in your drinking water due to a sudden backflow. According to an US EPA study, a great majority of homes have a cross-connection to a health hazard. In spite of regulations and building codes regarding backflow prevention, many products sold to trusting homeowners do not meet these standards. Conspicuous among them are the old-school water-powered pumps that sit inside the sump pit. Avoid them! Submerged in sump water and with a discharge pipe filled with water, they are sure to contaminate the drinking water during a sudden loss in main water pressure. Just check with your local Building Department. Our pumps have built-in backflow prevention. When hanging on the ceiling with suction and discharge pipes dry, they do not hold any sump water. The main ejector valve has a solid rubber diaphragm, which reliably isolates sump water from the municipal water, and a patented integral check valve which closes the main valve drip-tight by using the pressure of municipal water.
Sufficient water flow to the pumpInsufficient water pressure or flow will reduce the pumping rate of the pump or it may not operate at all. Minimize the length of piping and number of elbows to the pump. if you are on a private well, the water pressure is not sufficient and you have to use a battery back-up pump.
The "Bucket Test" of water flow: The water line to the hose spigot is usually only 1/2" and the spigot itself further restricts the flow. But these restrictions are similar to those inside the pump. (Do not test at the laundry tub, which often has smaller supply tubes and a more restrictive faucet.) You must be able to fill the bucket within the following maximum time for each pump model:
Prices and shippingEach pump is available in the classic design (separate suction and discharge piping) or with the optional Easy-Install Kit at the same price.
