Best Water Powered Sump Pump: The Buying Guide

Here are a number of factors that you have to check when you are out looking for such a sump pump.

The Requirements of your basement

As much as we would like to believe otherwise, water powered sump pumps are not suitable for all the houses out there. In fact, experts suggest that you only use it as a backup unit. It should come as no surprise that water powered sump pumps are way less powerful than the electric ones.

Therefore, if your basement is small and the flood in your area is not very frequent then a waster powered pump could act as your main one. Otherwise, it is better as a backup if you are looking for one.

But, you just must consider what your basement faces and requires before diving into a water powered sump pump amazed by its creativity.

The Way of Installation

Installing a pump is never easy unless it is a battery powered one that does not need much. When it comes to a water powered sump pump, you have more to do. In fact, you will have a lot of plumbing job to do and may need the help of professionals.

The problem however is not the difficulty but the compatibility for installation. In fact, there are houses that cannot connect the sump pump to a municipal water line. Therefore, buying a water powered sump pump will be absolutely pointless in this case. No matter how hard you try, you won’t be able to get what you want from the pump.

So, make sure that your house can have a water powered sump pump in it. Secondly check that the installation process does not ask too much of you.

The Gallons per hour (GPH) requirement

If you know how sump pumps work, you know that they usually have to lift the water to a certain height to get rid of it. In this case what matters is the width of the pipe and the speed at which the pump pumps water. You want this speed of the pump to be fast enough to deals with the water in your basement at the perfect rate.

However, water powered sump pumps, as you already know, are not the most powerful. Thus, it is necessary that you check the speed of the pump is good enough for what your basement requires. Or else, it won’t be able to pump water at the perfect rate or time.

The municipal line requirements

The water flow through the municipal line should also be able to meet the needs of the sump pump. Since it is going to be source of the sump pumps’ power- it has to have enough mechanical energy in it to power the pump. Therefore, you have to contact your municipal water line authority to know the speed at which the water can reach your sump pump.

Judging on the basis of that you can choose a sump pump that can run on such power and speed.

The Control and other features

You do not only use the sump pump to deal with the water in the basement but you do so to always be aware of trouble in the basement. Therefore, a sump pump usually comes with a number of features that help you be in peace when you are up out there working and minding your own business.

Just because it is powered by water does not mean the sump pump is free of such responsibilities. Firstly, the sump pump should have a good and effective alarm system. The alarm system should aware you right when trouble occurs and it should be loud.

There are other ways you could get this feature. Many sump pumps connect to the internet and send you notifications, texts, etc. about the status of the sump pump. But, yes, you can expect these sump pumps with such extra features to be more expensive.

Apart from that, the control of the sump pump should be very easy. In most cases, sump pumps start automatically thanks to the float switch. You should check that the type of float switch the sump pump comes with satisfies you.

Also, it is necessary that you check through other reviews that the float switch works well. Consider all these important features and also extra others if you feel like you need any.

The Build of the sump pump

A water powered sump pump will continuously deal with water. The humidity can damage it and so can the other conditions. Thus, you want the pump to be made of such materials that resist rust and corrosion.

Furthermore, you want it to be strong and sturdy in the face of pressure. It should come with no flimsy parts. Pumps like these are usually made of plastic, cast iron or stainless steel.

The Noise Level

The sump pump may have to run at any time, even in the middle of the night. And, you do not want it to make so much noise that it hampers your flow of life. So, make sure that it isn’t noisy.
