Do water powered sump pumps really work?
In multi-day power outages, this might mean the difference between a dry or flooded basement. The Basepump water powered pumps that we sell are very efficient, as well, removing 2 gallons of sump pit water, for every 1 gallon of city water used.
How do you test a water powered backup sump pump?
In order to test that your water-powered sump pump is working properly, you first need water in your sump. The easiest way to do this is simply unplug your primary electric pump until the sump fills with enough water. If the water inflow is too slow, you can manually add additional water to speed up the process.
How does a Basepump work?
Basepump® Theory of Operation A float is mounted in the sump pit above the normal high water mark. Your primary electric sump pump will handle all the normal pumping duties. When water rises higher than normal, the Basepump float in the sump is lifted and hydraulically activates the Basepump Ejector on the ceiling.
How does water flow into a sump pump?
There are a few ways the water may enter the sump pump: it enters by funneling into the pump through the designated perimeter drains in a basement's system of waterproofing, or by gravity because of groundwater or rainfall, if the basement happens to be below the water table level.
Which is better battery or water backup sump pump?
If the power outage outlasts the battery charge, you will effectively have no pump and your basement can quickly flood. However, water-powered pumps will run for an unlimited amount of time.
How much water does a water powered sump pump use?
A water powered sump pump uses 1 gallon of your city water to pump out either 1 or 2 gallons of water from your sump pump basin. Using the ratio of 1 to 2 at 1,000 Gallons Per Hour (GPH), this system will use 5,000 gallons of water to prevent 10.000 gallons from flooding the basement.
How high does water get before sump pump turns on?

Where does water from a sump pump go?
Unless you or your builder have made an error when connecting the sump pump, most homes will discharge water from the sump pit through a pipe in the wall of your foundation into either the yard or the storm drain.
Why is sump pump running with no rain?
The most common reason for your sump pumps keeps running while it is not raining is an increase in groundwater. Groundwater can come from many sources like nearby rivers or lakes, a broken pipe or nearby construction.
Why does my sump pump keep filling up with water?
The reason your sump pump keeps filling with water might be because it has a limited size or capacity. A stuck pump switch, check valve missing, high groundwater levels, and a clogged drain or valve could also be the cause. Solutions include upgrading, manually turning the switch, or replacing the valve.
How does a jet pump work?
A jet pump works by pulling the the water toward the surface instead of pulling it like submersible pump . It is a self-priming pump with no moving parts. This pump creates a fast jet of almost any liquid and drives another liquid by driving the pressure recovery in the diffuser.
How does a downhole jet pump work?
Downhole jet pump. The jet water pump uses unbalanced air pressure in its working. Its working is very similar as liquid sucks up by a straw. First of all, the pump fills with water. After coupling, the pump impeller rotates and lets water and air bubbles through.
How many suction pipes does a jet pump use?
It also uses when the pump is above the water source. The convertible jet pump uses two suction pipes to pump water out of the well. As the name of this pump suggests, you can connect the jet assembly to a suction tube and convert it into a shallow bore jet pump.
Why is the efficiency of a jet pump lower than that of a normal centrifugal pump?
The mixture of the velocity and the in let pressure of the gases or fluids causes the medium to flow out of the pit, storage tank, or well through the pump up to the outlet point. Due to some reasons like friction loss , the efficiency of the jet pump is lower than that of a normal centrifugal pump.
What is a turbine pump?
A turbine pump is a centrifugal pump that is essentially installed underwater and connected to an electric motor (install on the water surface) with the help of a shaft. Turbo pumps have high efficiency and mainly use for large pumping functions.
How does the Venturi effect work?
The pressure difference created by the Venturi effect draws liquid from the reservoir to the jet pump. Venturi can be separated from each other by a certain distance. The drive fluid and the stored fluid mix, and the pressure rises with decreasing velocity through the flow path of the increasing area.
How deep can a jet well pump be?
The convertible jet well pump can pump water from a depth of 70 feet. It is called a “convertible” pump because it can use as a shallow well pump for water sources up to 25 ft deep and a deep well pump for water sources up to 70 ft.
How does a well pump work?
How It Works. Jet water well pumps work by suction. The suction is created by producing a vacuum. An electric motor drives an impeller that forces water through a small opening, or jet. This increases the velocity of the water, and when it exits the jet it creates the vacuum that creates the suction. Just behind the jet is a Venturi tube, which is ...
What is the most common well pump?
Jet pumps are the most common for home water wells. Many people rely on water from a well to supply their homes. For thousands of years, manually operated pumps have been in use--and continue to be used in many parts of the world. In locations with electricity, well pumps commonly have electric motors. The most common well pumps today are jet pumps.
How deep can a well be pumped?
Depending on local atmospheric pressure, the limit is approximately 25 feet. Shallow wells can use a single drop setup.
Do jet pumps need to be primed?
Since jet pumps use water to create suction and move water, they must be primed, meaning that there is always some water in the pump. One-way valves in the pipes make sure that water will not drain out of the system.
What is a sump pump?
A sump is a naturally constructed pit, usually a hole carved below the main surface of your basement floor. This pit, known as a basin, holds the sump pump. The pump is equipped with valves that sense escalating water levels or pressure.
Why is my sump pump float switch jammed?
The float switch can also become jammed if the sump pump shifts within the basin and the float switch becomes pressed against the walls of the pit.
What is a pedestal sump pump?
Unlike a submersible sump pump, a pedestal sump pump consists of a separate motor and pump. The motor sits on a pedestal above the basin, with a hose running to the basin where the pump is placed. The pump sends water through the hose and out to your designated drain area. Because the motor is not submerged, it often has a higher lifespan than other sump pumps and can be accessed easier for maintenance issues. However, it also means it can be louder and take up more space than the submersible pump.
Why does my sump pump make a loud noise?
Loud noise can also indicate a damaged impeller. If the sump pump's impeller has become choked by debris like leaves, dirt, and sticks, the pump will screech and rattle as it attempts to suck water out of the basin. If the impeller becomes broken or otherwise damaged, it can make loud rattling noises when in use.
Why are submersible pumps quieter?
Because submersible pumps are completely submerged in the water basin, they are often quieter, save space in your basement, and clog less than a pedestal. However, due to the effects of water submersion, they may not last as long as other sump pumps. This is still the best option for homes with major flooding concerns.
How does a pressure switch work?
Below are several types of switches and how they work: Pressure switch: A pressure switch senses the amount of pressure in the water as it rises and triggers the action of the pump at a certain degree. Float switch: The float switch is essentially a float attached to the pump that sits on the surface of the water.
What is the switch that kicks on the pump?
As the water level rises so does the float and the pump kicks on. Diaphragm switch: This switch operates much like your diaphragm, flipping concave as the pressure rises and the back when it lowers, in and out. It is the most commonly used because it rarely gets stuck on or off.
What are the benefits of a water powered sump pump?
There are several important benefits that water-powered backup sump pumps have. 1. Water-powered sump pumps will never lose power or have reduced pumping rates. Battery backup sump pumps have a finite run-time (with a fresh battery, usually 5–7 hours of continuous use and longer if only run ...
What does rising water do to sump pump?
Rising water in your sump lifts the float, automatically opening the valve and allowing municipal water to flow through the pump’s ejector jet. Inside this jet is a nozzle and chamber that converts the water pressure into a vacuum.
How long does a sump pump last?
Battery backup sump pumps have a finite run-time (with a fresh battery, usually 5–7 hours of continuous use and longer if only run intermittently). Water-powered sump pumps, on the other hand, require no batteries and have a much more reliable source of power–your home’s municipal water pressure.

What is a check valve on a sump?
Also, a check valve on the suction pipe ensures water does not flow back into the sump. In many areas, a backflow preventer (dual check valve or Watts 9D style) is required on the water supply line as well. Within the sump itself, a float switch is attached to the suction pipe.
When do sump pumps run?
Water-powered sump pumps are emergency backups, so they only run when you need them most during power outages or primary pump failure. For an entire year, the amount of water required for an average homeowner would be comparable to running your lawn sprinkler for just several hours.
Can you use a water pump as a backup?

How does city water flow through a basement?
The city water flows through a constricted area , and is forced through an ejector. At that constriction water speed increases causing a pressure reduction. This pressure reduction literally sucks water from the sump crock. Sump water then combines with the flowing city water and exits your basement via a discharge line.
Can a sump pump work off a well?
For this reason it will not work off of a well unit during power outages. One major drawback to the water powered sump pump is that it costs considerably more money to run over a specific time period than an electric sump pump, since it is less efficient considering the cost of water. This is why it is intended for use as an emergency pump.
