How To Best Water Powered Backup Sump Pump

Even though we are aware of the advantages and disadvantages of a water-powered sump pump, there are still several factors that you need to know before deciding to purchase one.

Town water or well?

You must be connected to a municipal water line to use this device. This is because if you have a well, you will not be able to use a water-powered sump pump.

Water pressure and pressure settings

The water pressure of a water-powered sump pump is similar to that of a showerhead. If you point the showerhead in an upward direction and direct the water away, the more pressure you apply, the higher and further the water is pushed away.

As the sump pump pit is often situated at the lowest point of a basement, the pressure must be high enough for the water to flow up the pipe and away from your home. On most sump pumps, the pressure is measured in meters or feet.

Gallons per hour (GPH)

One of the essential elements of a water-powered sump pump is how much water the device will pump in gallon-metrics for an hour. So, you need to figure out how much water needs to be taken out of the basement. For instance, in a regular 18 inches diameter sump pump pit, one inch of water is equivalent to a gallon. On a rainy day, when your electric pump stops operating, you can take a yardstick and hold it in to check the rising water level.

The change in this level has to be multiplied by sixty. In this way, you can assume the gallons of water flowing through the sump pit every hour.

Installation

Installation is a natural process if you are familiar with a tool kit, but if you aren't, then it's wise to take the help of a professional. However, most of the people choose to do it themselves since the instructions are pretty clear. Although each model of the sump pump device has its own particular instructions, generally, it is the same.

Still, water-powered sump pumps are tricky to install, as they go into the plumbing of your basement. We’d recommend taking expert help if you’re not sure about how to install a water-powered sump pump.

Drainage

Drainage is another important factor because the ability to drain the water to the outdoor area efficiently is a vital feature of a water-powered sump pump. There are two methods regarding drainage.

You can tie the sump pump in your current discharge pump, which will make the installation process more accessible, or you can keep it in a separate discharge pipe only for this pump, which, albeit useful, might complicate the process.

Basement and sump pit size

There are different types of sizes when it comes to a water-powered sump pump; some are only suitable for small basements; some require a specific sump pit size while others are ideal for basements of all sizes.

Therefore, you need to keep in mind the square footage of the basement and the sump pit's size before choosing a sump pump.

Noise Level

Different models of water-powered sump pumps come with varying levels of noise. Some of them are noisy, and some are quiet, but none of them are extremely loud.

Most people prefer to choose the one that makes a loud noise because this gives them an indication of whether the pump is operating or not, while other people want a pump sump that promotes less noise. Fortunately, they can be tested so you can decide which one works best for your home.

Construction quality

Before buying a sump pump, you need to know about its design and construction quality. It goes without saying that you have to choose a pump that is made of durable and sturdy materials that can last for a long time.

Since the device will be continually surrounded and immersed in water, you should choose a sump pump that is resistant to corrosion and rust.

Warranty

It is better to purchase a water-powered pump sump that has a warranty than one that does not. However, the policies vary from one to another in different models, so choose one that works for you.

Alarm

Most of the water-powered sump pumps come with an alarm feature while others do not. The alarm is usually built-in to let you know when the main pump has stopped operating and when the sump pump is supposed to be activated.

We would suggest you get a pump with an alarm system, which makes it easy to keep track of its operation.

Check valve

A check valve on the pump’s discharge line prevents the water from coming back in the sump pit when the device switches off. It is sometimes called a ‘one-way’ valve. This is because it only allows water to flow in one particular direction. Without a check valve, the device will turn off automatically after a specific amount of water is taken out of the sump pit.

The remaining water in the discharge pipe will gather in the sump pit, which might cause the sump pump to dysfunction prematurely. Hence, it is better to choose a sump pump with a built-in check valve.

Efficiency

Another main factor is efficiency. Naturally, all water-powered sump pumps run efficiently, but you can compare the description of the different models and pick the one that meets your needs. Most sump pumps use a gallon of water to discharge about two gallons of pump sump water. You need to keep in mind that you are accountable for the town water, so you need to adjust your water bill accordingly.

However, most people are willing to pay a higher water bill just to keep their basement dry.

Methodology

The town water for your sump pump must be stored in a large vessel or container. It can either be a reservoir or a tank. This water flows through various small sets of pipes to individual residences.

Due to this limitation, the water travels faster, which then results in a reduction of pressure. Consequently, the pressure reduction channels out the water from the sump pit through suction.

Cost

The cost of a product is one of the critical factors. Before setting out to buy a water-powered sump pump, you need to set a budget for the device. Some of the sump pumps in the market are more expensive than others, so keep this in mind as you look for the right one. However, the expensive ones might not necessarily be the best, or the cheaper one might not necessarily be the worst.

Therefore, you need to choose a sump pump with all the features and benefits you are looking for within your preferred price range. The products listed in our article vary in quality and price; you’ll definitely find that fits the bill if you read the in-depth reviews.

Advantages of the water-powered pump sump

Usually, at first glance, a water sump pump might look like a complex device, but they are quite easy to operate. Most people ignore how powerful water pressure can be, so they underestimate the power of these pumps. However, there are few benefits of using a water-powered sump pump, some of which are:

Unlimited run time

Since your property's municipal water pressure operates these devices, the sump pumps will be able to run for an unlimited amount of time until the water is available. And we’re all well aware that municipality never runs out of water, except for rare circumstances.

Doesn’t rely on electricity

Also, during extreme weather conditions, the electricity supply is likely to be cut off, and this is where having a water-powered sump pump comes in handy because it doesn't need electricity to operate. It’s a god-send when you’ll be out of electricity for hours at a stretch.

No need of a battery

In a water-powered sump pump, you don't have to bother about checking, maintaining, and replacing a battery or even keeping an eye on the charger to monitor its usage. It’s super convenient.

Water-powered sump pump disadvantages

Cost

The amount of water that is needed for the device to function adequately is quite massive. This will cause a rise in your water bill because of the operating costs.

Installation

Compared to battery-powered sump pumps, this type of pump is a bit more complicated to install. Since the water-powered sump pumps are connected to the house's water supply hose, they must be properly installed.

Using water powered sump pump

Water-powered sump pumps are designed to prevent flooding in your basement. The sump pump is situated at the lowest area or hole known as ‘pit’ within the basement. It is essential that you install it at the lowest point of the property.

The pit works in two ways: it works as space for the water to drain into, and it activates the pump when there is sufficient liquid in it. Next, the water is carried from the pump to a set of pipes, in an area where the water can safely be drained.

By safe area, it means a place where the water cannot damage the furniture or any other object kept in your basement. The set of pipes operate with the help of a check valve so the water can only travel one way, which is away from the sump pit. This decreases the risk of the water coming back through the pipes.

For instance, during heavy rain or storm, water will start to fill up the sump pit. The heavy rain causes a power outage, which, in turn, shuts off the primary sump pump.

If you have installed a water-powered sump pump, then the water in the pit will travel above the inactive float of the main pump and, at the same time, trigger the device's float.

The activation of the float causes a tap to open inside the pump, which is usually installed above the sump pit. Then this valve sends the water from the house's municipal water supply by the pump ejector.

The water is then safely discharged outdoors. In this way, the device completes its process each time the water level crosses the normal range.

Final Words

Water-powered sump pumps are the perfect backup pumps for houses that are connected to city water. These devices are quite efficient and robust and will be able to last you for a long time.

It might be a little overwhelming while choosing the best water powered sump pump out of the many available in the market. Still, we hope that the information and reviews provided in this guide will help you make an informed decision.

To round it up, you can go for the Liberty Pumps SJ10 if you have some money to spare. It has amazing features, and well worth the investment, it’s a clear winner as it stands out against other products.
