Water-Powered Sump Pumps: The Ultimate Buying Guide

Water-powered sump pump protects you from flooded basements and our buyer’s guide will offer you all that you need to know before getting one for yourself.Water powered sump pump

Is it better for the town water or well?

If you are wondering whether it is good for town water or well, we can say that if you have a well, this pump is not for you.

This kind of pump requires having the constant water pressure from a town water supply.

How can I measure water pressure?

In order that you pump works, there has to be a required minimum amount of water pressure.

It will do more work for you if you have higher water pressure.

So as to know how much your water pressure is, you should call your water supplier and get this information or measure with an inexpensive gauge found at any hardware store.

The required pressure is usually between 20 and 40 minimum PSI.

How does the pump functions?

If you are thinking about how this pump functions we will tell you that your town water starts in a large container and is directed through pipes to your house.

This constriction usually forces the water to move faster and reduce the pressure.

That way, the water from your sump pit is sucked out, so the sump water joins the town water in a discharge pipe and shoots out of your house.

Their aim is to keep on pumping during a power outage or electrical pump failure.

What does GPH stand for?

The abbreviation stands for Gallons per hour being one of the most important features of a water-powered sump pump.

This number shows how much water the pump can eject in gallons in an hour.

That way you can calculate how much water you need to get out of your basement.

So as to get a rough estimate you should take a look at the following:
In a 18” diameter sump pit, an inch of water equals about one gallon.

On a rainy day once the electric pump turns off you should stick a yardstick in and hold it still for exactly one minute.

The water level will change and you should note it.

If you then multiply the rise in water level by 60 you will get a rough idea of how many gallons enter your sump pit in an hour.

How important is the efficiency?

Efficiency is what you expect from your pump.

Most pumps use one gallon of municipal water so as to be able to remove somewhere between one and two gallons of sump water.

This municipal water is paid through bills and the majority of users accept to pay a little extra if their basements will remain dry.

What about installation?

In our descriptions, we spoke a lot about installation issues.

There are some types of pumps which can be installed by any homeowner, but there are also those which require a plumber or at least an experienced user when it comes to installation process.

Concerning the installation, you can find YouTube videos explaining everything related to the installation of the top three pumps on our list.Water powered sump pump

Where does the water go?

The good question is where the water goes, and there are two options.

The pump can be tied into your existing discharge pump, which is the easier solution, or you can put in a designated discharge pipe just for this pump, which is a little bit complicated.

Have in mind that the majority of users prefer the designated discharge.
