How to Buy the Best Sump Pump for Your Needs?
If you live in an area where heavy rain and angry storms are the norm, then you probably rely on a sump pump already. If you are on the market to buy a new one or the first one, you need to know some things. Let’s see a short buyer’s guide when it comes to getting the best pump for a home or a business.
Type of Sump Pump
- There are two types of pumps: submersible and pedestal. On this list of sump pumps reviews, we had one pedestal sump pump and plenty of submersible ones.
- Pedestal sump pumps make a good choice when you want easy access to their above-ground motor. They are noisier than the submersible ones, but easier to repair and maintain. Not all of them can move massive amounts of water, however.
- Submersible sump pumps are quieter – as they go deep inside your sump pit. However, they are harder to reach, maintain, or repair. Their major advantge is that they can stand floods or extreme weather events better than their counterparts.
Sump Pump Motor Size and Water Flow
Another critical criterion for your purchase decision of the best sump pump for your home is the motor size and, consequently, the water flow. As you can easily figure out, the more powerful the motor is, the more water it can move.
If you live in an area with moderate rainfall and few to none extreme weather events, a mid-range powerful pump with lower water flow may be the best for your needs. However, in climates marked by heavy rainfall, hurricanes, extreme storms or heavy snowmelt, we recommend a heavy-duty sump pump with powerful motor and above 5,000 GPH water flow.
Alternative Power Source
In hurricane-vulnerable areas, you know that power outages are also the norm, besides heavy rain and general panic. In this case, we recommend you get a sump pump that comes with a power back-up (on batteries) that can still pump out water from your home even if you don’t have electricity. Such units are also very useful for hospitals and medical offices/clinics, kindergardens, restaurants and cafes, small businesses, and so on.
Nobody wants a lake in the basement to ruin lives and businesses, even if the power is out. Our recommendation is to consider a sump pump brand that offers battery back-up as well to the main pump.
If you have moderate rainfall and extreme weather phenomena in your area, you should look for a mid-range pump that will hold for years with no problems. Nevertheless, if you live in frequent storms’ area, you should consider a pump that won’t let you down when you need it the most. Look for pumps tested on tens of hundreds if not million cycles. Also, look at their warranties. The best one – catastrophe-wise – is the one featuring 3 and more years of warranty.
Best Sump Pumps: FAQs
What HP Sump Pump do I need for my Home?
For a medium-sized home in an area with moderate rainfall and weather phenomena, a 1/2 HP sump pump should be enough. If you own a larger home in an area with high water tables, 1/3-HP to over 1-HP pumps may be the best choice.
How often should I replace my Sump Pump?
According to the US Department of Housing and Development, the average life expectancy of a sump pump is 10 years. Of course, you should replace your sump pump immediately if it breaks.
How do I know my Sump Pump is going to break?
You know your sump pump is going bad when it shows one or more of these signs:
- The pump starts going through constant cycles of on and off;
- It emits new noises or stars to be noisier than usual;
- You know it closes in towards its 10-years life expectancy threshold;
- Sump pump runs constantly while consuming more energy than usual;
- You need to fix small things or replace small parts.
Sump Pumps – The Ultimate Guide
Approximately 60% do U.S. homes have underground moisture problems. This is the cause of $1000/inch being the average cost that the people of this country have to pay for damage by floodwater.
Sump pumps were introduced in the market to contain the damage caused by such reasons. Sump Pumps are submersible pumps installed at the lowest point of a basement or crawl space.
A sump pit is dug at that lowest point where the pump is installed. The sump pump that removes the water in the pit by pumping it out to the closest detention point. This could be a storm drain or a dry well. A float switch triggers the sump pump. That switch turns on only when the water being gathered in the sump pit reaches a certain trigger point. Prior to the commencement of the entire procedure, this trigger point has to be determined.
Should I have an Alarm?
You may not necessarily need an alarm to operate these sump pumps as they are usually hardwired into the electrical system of a home. They may even have a battery backup.
Nowadays, all newly built homes consist of these pumps whereas owners of homes that are older need to have this system instated into their homes to avoid unforeseen events like basement flooding.
Common Problems with Sump Pumps
Apart from a storm drain or a dry well, these pumps might discharge into sanitary sewers in older installations. This type of discharge was once an acceptable practice. In today’s world, this practice is considered to be a violation of the plumbing code as well as the municipal laws. This practice has become a violation due to its ability to overwork their sewage treatment system.
Although the Municipal Department strongly urges homeowners to renovate or rebuild their sump pump system so that the discharge may be disposed of away from these sanitary sewers. They have even implicated fines for non-compliant citizens.
Once you get a sump pump installed in your home, you may need to test it regularly to make sure that it works perfectly when the next big downpour occurs. To test your sump pump, follow these simple steps:
- Fill the sump pit till its trigger point with a bucket.
- Once the water triggers the indicator, the sump pump would turn on automatically.
- When the pump turns on, water may start draining from the pit.
- After the sump pit is empty, the sump pump should turn-off by itself.
What type should You buy?
Typically, there are two types of sump pumps. Location of the motor is the only difference in both these sump pumps.
Pedestal Type (Column Pump) – Motor of the Pedestal pump is located above the sump. It consists of a long drive shaft connecting the motor & the hydraulic portion. This is the exact location of the impeller.
Submersible Type – On the other hand, the submersible pump is relatively shorter. The location of the motor is right above the hydraulic portion. It can be immersed without causing any damage to the pump.
How to properly Size & Locate a new Sump Pump?
Sump pumps are commonly sized in accordance with horsepower. The plumber’s experience is the most important factor to consider while sizing the pump. Nonetheless, estimation of flow rate & total dynamic head (head requirements) are the basis of technical guidelines for sizing sump pumps. Similarly, an estimation of the flow rate is established on the area of the basement or wherever the sump is located. Another considerable factor is the type of soil (either sandy or clay).
To find out about the head required for the pump, calculations by taking measurements of the static head, friction head and operating head.
- The height difference between the level of water present in the sump and the top-most point inside the discharge pipe.
- The basis of the friction head is the entire length of the discharge pipe as well as the quantity of fittings.
- Pressure at the point of discharge, also called atmospheric pressure for the majority of installations is the operating head of the pump.
- These head requirements as well as the flow rate are used for selection of a compatibly-sized pump with the help of manufacturer’s pump performance curves then.
- Undersized pumps would be unable to discard enough incoming water.
What Tools & Supplies are needed to setup a Sump Pump?
While reviewing installations of sumps, there are five key features that require consideration.
An outlet for Ground Fault Circuit Interrupter (GFCI)
GFCI outlets are commonly used in kitchens and bathrooms in the U.S. This outlet has been made mandatory by the National Electrical Code (NEC) for installation of sump pumps. If a GFCI outlet trips, then the pump wont function. Excessive debris in the sump may lead to a clog in the pump inlet. The clog may reduce the pump’s capacity or jam its impeller. This would result in a “locked rotor” condition. To help lessen the quantity of debris in the sump, a basin made up of compatible material (concrete or plastic) and a cover would be the appropriate choice.
Debris present in the Sump
Installed in a pump discharge pipe, a check valve is used to stop the water from flowing back into the sump when the pump stops. This prevents the pump from a rapid cycling situation in which it pumps water that flows back from the discharge pipe constantly. Rapid cycling decreases the pump switch’s life.
Presence of a Check Valve
Check valve is a requirement for most sump pump manufacturers. It is very important to keep the check valve while conducting a sump pump installation analysis or to take a photograph of its presence for the record.
Reviewing the Float
Reviewing the float to make sure that it is free to move around is also very important unlike the pumps that have a switch instead of a float. A popular method of controlling a sump pump is with the help of a float. If the float touches the sump basin when installed initially, it might be able to operate in a proper manner.
Presence of an Air Release Hole
With the passage of time, accretion of mobile mineral deposits would lead to an increase in friction. This friction might end up blocking the float from moving entirely. This can result in a delay with the motor’s activation or it may even result in the continuous running of the pump. When something like this happens, it may even shorten the life of the sump pump.
Floats are usually controlled by a float switch in tether length. Usually, the float switch is 3.5-inches in tether length. Float switches have switch cords. These cords are prone to loss of ductility overtime and may be unable to activate right away. The heat emission from a pump that runs for long durations is the cause of loss of ductility.
Lastly, the most critical part of a sump pump is the often overlooked air-release hole. It is vital to have on pumps that have an aligned strip of water below the impeller at the rare end of the pump. The presence of an air-release hole is important as it allows the air to escape from the hydraulic section.
If the air remains to be in the pump, the pump’s impeller would not be left with enough force to carry the flapper to the check valve. Due to this reason the pump will not be able to discard water. The sump pump will then start to work more like a fan causing an air-locked condition.
Manufacturers who produce rare inlet designs recommend that consumers should drill an air-release hole in the discharge pipe right below the check valve to avoid air-lock situations.
What is the Cost of a new One?
The average cost of a new sump pump ranges around a thousand dollars, which most homeowners pay including installation. Costs of these sump pumps depends on a number of factors.
On the other hand, replacing a sump pump is far more cost-effective than having a new one installed. Mostly, replacing a sump pump excludes the manual labour of digging, plumbing costs or electrical upgrades. In addition to that, homeowners prefer replacing their own sump pumps which cuts their cost of replacement as high as $700.
Factors that affect the Price of Sump Pumps
Whether it is an installation of a new pump or a repair job of an existing one, the geographic location of the pump is going to directly affect the cost of your project. Similar to variations in home prices in different cities, sump pump costs vary in the same manner.
It may cost more to have a sump pump installed in Illinois, but a lot less in Denver. The most constructive way would be to get quotes from multiple service providers.
Besides new installations & replacements, there are a number of other factors that may substantially affect sump pump prices.
When should I hire a Pro?
Seemingly, the installation cost estimation of sump pumps is above a thousand dollars, then consider the fact that you may want to hire a professional to do this job for you. You may not be able to comply with everything that replacing & installing a sump pump may require. Follow this link to find a professional to do this job for you.
How to know if your Sump Pump is dying?
Just like a dishwasher with a broken motor, there are a few signs that indicate an appliance is broken. With sump pumps, if there has been a case at your home of a basement flood then evidently, your sump pump is either broken or too small to handle the pressure.
What are the Signs that I need to replace One?
Apart from flooding, other factors that also hint towards you getting a replacement for your sump pump include:
- Electricity – To operate, a sump pump requires power. If every electrical appliance in your house is working except your sump pump, then there might be an electrical issue inside of it. If that is the case, then it is strongly suggested that you do not attend to the matter yourself. As water and electricity do not go together, it is safer to have a pro look at it and fix it if possible.
- Noise – Sump pumps do not make a lot of noise while running as they do not have many parts. If strange noises start coming from the sump pump, there is a chance that the impeller is bent. If that is the case, you will not be able to move the water and chances of a flood become imminent. Henceforth, if your sump pump is making too much noise, you might have to consider getting a replacement.
What is the Cost of Replacement of a Sump Pump?
Fortunately, the average cost of replacement of a sump pump is around $1,022, which is relatively cheaper as compared to other plumbing projects.
Can I replace my Sump Pump myself?
Nonetheless, if you choose to make it a DIY project, you may be able to save a huge amount of money as the cost of a new sump pump is roughly around $300. In addition to that, you may need necessary permits to attempt such a task. However, working with cement and electricity are difficult tasks and should be given serious thought before you start to work with them.
How often do You need to replace?
Sump Pumps are created in a way to endure heavy workload. They end up covered with dirty water & have to deal with perpetual gathering of debris and other objects. The sump pump has an average lifespan of five to seven years.
How to maintain a Sump Pump?
You may be able to increase the lifespan of your sump pump by conducting periodical maintenance procedure. The periodic maintenance includes the following items.
- When the weather is dry and there is no possibility of usage of the sump pump, pour enough water into the sump pit so that it runs a full cycle.
- Pour vinegar through the pump’s pipelines to discard any build-up.
- Make sure of the float not being choked and moving properly.
- Make sure that the pumping-out of water is smooth.
- Pumps with battery back-ups need a replacement once in every three years.
- If the pump’s motor doesn’t shut off, listen carefully for any weird motor noises.
Would You require a Back-up Sump Pump?
Basically, you do not need a back-up sump pump but you should consider having one. A back-up sump pump would reduce the possibility of overflowing water into your sump pit. It may also reduce the chances of occurrence of a complete basement flood. By any unfortunate chance that your power goes out due to which your primary sump pump would stop working, a battery operated or water powered back-up sump pump would prove to be of great use.
To sum it all up, the maintenance of a dry basement has become very easy with the presence of sump pumps. These pumps are a very useful appliance. If properly maintained, the may last for ten years of smooth running at the very least.
With how well they perform at keeping areas dry and free from flooding and mold development, it’s clear that sump pumps are ideal to own.
Some are more affordable than others, but regardless of what you pay for it, it’s important that you have one. The best sump pump should last more than a couple of years, and it should be easy to use and reliable. You should also look at the best submersible well pump for more options.
