I Tested And Reviewed 10 Best Sump Pump For Crawl Space (2023)

I recently purchased the PumpSpy 1/2 HP Cast Iron Sump Pump with Corrosion and Rust Resistant Housing, and I must say, I am extremely satisfied with its performance. As someone who repairs swimming pools, I occasionally need to drain them, and this pump has proven to be a reliable and efficient solution.

The build quality of this pump is impressive, with its solid and heavy construction. While other brands may have a more elegant design, this pump's smooth, enameled metal housing is both durable and aesthetically pleasing. It gives me confidence that it will withstand regular use without any issues.

Installation was a breeze, with the only challenge being the removal of the old pump. The included manual provided clear and easy-to-understand instructions, making the process hassle-free. Once installed, the pump worked like a charm, quickly fixing the problem in my basement. Its powerful performance ensured that the water was efficiently pumped out, effectively resolving the issue.

I also appreciate that this pump is equipped with a vertical float, which allows it to lift water up and out of my sump well onto the street. With a 40-gallon sump, this pump is able to empty it in just 10 to 15 seconds, shooting a jet of water about 2 feet from the discharge line. This level of efficiency is impressive and gives me peace of mind during heavy rainstorms.

In terms of longevity, I have high hopes for this pump. The cast iron construction, coupled with the vertical float design, leads me to believe that it will last for at least three to four seasons. Of course, only time will tell, but so far, I have had no issues whatsoever.

The Little Giant system is incredibly easy to install and comes with clear instructions that make the process a breeze. It operates quietly and has a quick response time when it comes to pumping water. All the necessary pieces are included, so there is no need to make additional purchases.

I have had this bucket and pump installed in my yard for two years now and it has been a reliable solution for moving ground water away from my swimming pool and back patio. I have even connected some of my gutter downspouts directly to the system, which has worked flawlessly. The pump is able to handle a large amount of water despite its small size.

One tip I have is to clean and lubricate the switch every 6 months to ensure smooth operation. While the flexible tubing that comes with the system is suitable for temporary use, I would recommend upgrading to PVC pipe and a Wayne or Zoeller check valve if you plan on using it in your home to protect against flooding.

I also buried this tank and pump in my yard 3 years ago to address poor drainage in my backyard. Since then, the system has been working flawlessly. In fact, I recently purchased a backup pump just in case the old one fails, particularly during the spring rains. Thanks to this system, I no longer have issues with my septic tank backing up when the ground becomes saturated with water. This has saved me from having to spend hundreds of dollars on septic tank pumping.

I have also installed this pump in my crawlspace a few months ago and it is still working perfectly. My only complaint is that it doesn't pump until the water level is a bit lower, but overall, it has been a reliable and efficient solution.

I recently purchased this pump and I must say, it exceeded my expectations. I was initially hesitant to hire a pool guy for draining my pool, so I decided to give this pump a try. And boy, am I glad I did!

Setting up the pump was a breeze. I didn't even need to read the directions, as it was very straightforward. All I had to do was buy a hose and clamp, attach it to the pump, drop the pump into the pool, and plug it in. I did have to use an extension cord, but that was a minor inconvenience. It's important to make sure the clamp is tight on the hose, as this pump is incredibly strong. I used a 100' 1.5" hose and it worked perfectly for me.

The speed and power of this pump are truly impressive. It was able to remove 2-3 thousand gallons of water per hour using a 1.5" backwash hose. I couldn't be happier with its performance. I highly recommend this pump to everyone in need of a reliable and efficient solution for draining their pool.

In fact, I was so impressed with this pump that I decided to order two of them. The alternatives I found in local stores were priced at up to $300, so purchasing these pumps online was a much more cost-effective option for me. I had drainage issues in both my driveway and backyard, and I needed a solution to divert heavy rainwater away from my home. I came up with a creative solution using heavy-duty 5-gallon buckets with lids.

I drilled holes in the sides and top of the buckets to allow water drainage and to accommodate the power cord and output hose. I attached landscape fabric to the sides of the buckets and buried them slightly lower than where the water accumulates. I placed the pumps in the buckets and connected them to 1.5" plastic discharge hoses that I purchased locally at a reasonable price. I ensured that the power cords had dedicated sources and placed the discharge hoses in shallow trenches leading to drainage ditches.

To test the system, I used a water hose, and both pumps worked flawlessly. When the water filled the buckets, the floats went up, and the pumps automatically turned on, quickly eliminating the water. Once the water was gone, the pumps turned off automatically. I was impressed with the efficiency and reliability of these pumps.

To give the setup a more professional look, I covered the discharge hoses in the trenches with white landscape rocks. Overall, I am completely satisfied with the performance of these pumps and would not hesitate to recommend them to others in need of an "automatic" drainage solution. While only time will tell their long-term reliability, as of right now, I am confident in their effectiveness.

I recently used this pump for the first time and it exceeded my expectations. I needed to run vinegar through a boiler and the pump worked flawlessly for this task. I was able to easily connect the washing machine hose to it using the included adapter and my quick connect brass adapter. I left it running for about an hour and it did the job efficiently.

I actually bought two pumps as I had a pool filled with water, dirt, leaves, wood, and other debris. However, I found that using just one pump with sump pump tubing was sufficient. I also used a milk crate to help filter out the larger debris.

In addition to the boiler and pool tasks, I also used this pump to move water from a collection tub to a rain barrel. Initially, it didn't work as directed because the release position with the auto float was higher than the stated instruction position. However, I replaced the tub with a taller container and the auto action worked correctly.

I had to exchange the first pump I ordered as it stopped working, but the process was easy and I received a replacement. I stored the replacement without using it until last week when I needed to drain the above ground pool of all the muddy water from the winter. The pump did an excellent job and I was impressed with how well it worked. I made sure to clean it with fresh water after use and let it dry before packing it up again.

After using this laundry pump for a while, I feel compelled to share my thoughts on it. Two years ago, I moved my laundry to the basement and needed a pump to elevate the water. I initially bought an all-in-one solution from a local home store that claimed it wouldn't fail and had an "internal check valve." However, I soon realized that I made a naive choice.

The pump included in the solution was made from low-quality materials and quickly failed when it became submerged in water. Frustrated, I started searching on Amazon and came across Zoeller, an American family-owned company. Intrigued by their promises and reputation, I decided to give their laundry pump a try.

Installing the Zoeller laundry pump was straightforward, and I have been impressed with the results. It has been quiet and reliable, never faltering under pressure. Even when running multiple devices simultaneously, such as a heat pump vent-less dryer and a dehumidifier, this pump handles the workload effortlessly.

Some might argue that it's only managing a few devices and that it needs to handle more to be truly impressive. Well, let me tell you, my municipal water is extremely hard with high calcium content. To prevent any issues with my pipes, I added a water softener to the system, and this pump handles the brine with ease. It has proven to be reliable and efficient, even with the added challenge.

I can confidently say that this laundry pump is the Tom Brady of its kind. It performs consistently well without any hiccups, just like the legendary quarterback. It is the GOAT (Greatest of All Time) in its category, and I highly recommend purchasing it for your laundry needs.

This submersible water pump is an excellent investment for anyone in need of a reliable and powerful pump. Whether you're dealing with a flooded basement or excess rainwater in your backyard, this pump will get the job done efficiently and effectively.

One of the standout features of this pump is its ease of use. Simply plug it in and watch as it quickly and consistently pumps water out of your desired area. It's a hassle-free process that requires minimal effort on your part.

The pump's performance is impressive, pumping water fast and effectively without any issues with tiny debris or clogging. As long as you remove larger debris like leaves beforehand, this pump will handle the rest with ease.

However, there are a couple of concerns to address. One user discovered a rusty bolt holding the propellers on, which raises questions about the overall durability and longevity of the pump. Additionally, there are no instructions provided on how to remove trapped water from the housing, which may lead to potential rusting if not properly addressed.

Considering the concerns mentioned above, it's understandable that some may question the long-term reliability of this pump. However, it's important to note that the pump worked exceptionally well during its initial use. The power and efficiency it demonstrated were highly commendable.

For those who require a one-time solution or are willing to perform regular maintenance and cleaning to prevent potential issues, this pump is a cost-effective choice. However, if you're seeking a more durable and long-lasting option, it may be worth exploring other alternatives.

I recently started using these pumps for my company and I must say, they are excellent. If you have a small sump in diameter, this is the perfect pump for you. One thing to note is that a check valve is needed in such a pit to prevent constant cycling. Without a check valve, the pump would cycle every 30 seconds as 3/4 of the water pumped would make its way back to the pit. However, a simple trip to a local plumbing supply store for a 6 dollar check valve resolved this issue completely. I was just in time as heavy rains were expected tonight. I also recommend elevating the pump slightly in the pit for optimal performance. These pumps have a great track record with long documented life, so look no further, especially if you have a small space to work with.

One of the standout features of this pump is the diaphragm switch. It allows the pump to work with a low profile, unlike those with a large float. The diaphragm switch detects 7-10 inches of water to activate, making it efficient and reliable. I recently replaced the original pump installed by the installer 25 years ago with this Little Giant pump, and it has been working flawlessly. I have attached a photo showing the old Little Giant 6-CIA pump and one of the barrel pits.

I also found another use for this pump – pumping water off of our in-ground pool cover. Instead of using a bucket, I had to do a little rigging to ensure the pump wouldn't tip over or try to suck up the cover. I attached it to a metal basket to keep it in place. Despite the hose having to come up over the side of the pool, I have had no issues with backwash. I didn't opt to use the auto on/off feature, as I wanted to control it from my deck. So, I used an extension cord plugged into a remote control outlet, similar to those used for Christmas lights. In the other outlet, I plugged in a night light to easily tell when the pump was on or off. This setup worked like a charm, especially since the pump is extremely quiet. This is actually my second Little Giant pump, as the first one still works fine, but I wanted a little more power and speed. I highly recommend this brand.

I recently purchased this pump due to concerns about potential flooding and it has exceeded my expectations. What immediately caught my attention was its unique and stylish design, which stands out from other dull and plain black pumps. Additionally, the pump's heavy and sturdy appearance instills confidence in its durability.

The standout feature of this pump is its automatic switch function. It automatically starts pumping when the water level reaches 1-1/2" and shuts off when the water level reaches 1/4". This not only saves the hassle of constantly monitoring the pump but also ensures efficient water removal. Furthermore, the pump operates quietly and efficiently, quickly draining water without causing any disturbance.

I also appreciate the versatility of this pump. Apart from preventing flooding, I have been using it to keep the end of my driveway parking area dry during heavy rains. In this regard, it outperforms other pumps I have tried in the past. It activates with a significantly lower water depth than most other pumps, making it highly effective. Moreover, its compact size allows it to be inconspicuous while still providing ample power to handle heavy downpours.

One noteworthy feature of this pump is its built-in screen, which effectively prevents leaves and larger debris from entering the pump. This proved to be extremely useful when I used it to empty my pool, ensuring a hassle-free experience.

Although it may take slightly longer to remove water compared to other pumps, this is a small tradeoff considering the pump's effectiveness and convenience. It utilizes a water hose for operation, making it suitable for a variety of tasks.

I recently purchased the Superior 1/3 hp 92341 Cast Iron Sump pump and I must say, I am extremely impressed with its performance. As someone who is not particularly handy, I was a bit skeptical about my ability to install and operate a sump pump. However, the manufacturer deserves praise for creating a simple and efficient product.

Living in Texas, I have experienced an unprecedented amount of rainfall over the past month. As a result, my driveway turned into a pond. After a costly call to the plumbers to fix the poorly designed drain system, I decided to take matters into my own hands and purchase a sump pump. After some research, I settled on the Superior 1/3 hp 92341 Cast Iron Sump pump.

I have been using this pump for the past four weeks, and I must say, it has exceeded my expectations. Even during the heaviest downpours, this pump has held up and discharged the water incredibly quickly. It has proven to be a reliable workhorse, which is exactly what I needed.

One piece of advice I would give is to invest in a larger drain hose. Initially, I tried using a garden hose adapter valve and PVC pipe with couplings, which worked fine for general use. However, during heavy rainfall, I found that I needed a larger hose to handle the increased water flow. I ended up purchasing the Flotec universal 24ft hose kit with a 1 1/2 adapter, which has been working beautifully. The larger hose has significantly improved the draining process.

In hindsight, I realize that I spent unnecessary time and effort on couplings and extending PVC pipes. All I really needed was the 1 1/2 to 3/4 inch garden hose adapter. I found some of the reviews mentioning additional couplings and backwash valves to be a bit overkill for my situation. The basic adapters have worked perfectly for my driveway flooding issue.

Additionally, I took the precaution of wrapping a wire mesh screen around the base of the pump to prevent debris from entering. This has worked well for me. I also placed the pump in a plastic crate for storage purposes, but I have found that it works even better when it's outside of the crate. The crate provides an option for quick use and storage, and I lined it with wire screen for double filtering if needed.

The before and after photos of the sump clearly show a big improvement in handling rainwater. The pump was installed in an old root cellar beneath a farmhouse built in 1880, which used to hold water whenever the ground was moist. Previous small pond pumps couldn't handle the amount of water, but this pump kit proved to be extremely powerful. After installation, it quickly cleared out the remaining water in a matter of seconds. Its power suggests it would work well as a sump pump or for draining a swimming pool. Although it has only been a week since installation, its performance so far has been impressive.

This pump is truly an awesome product. The anticipation for the first rain with the new pump was met with perfect results. The customer is grateful for such a valuable product that delivers on its promises.

The customer needed a pump for a grey well at their cabin, and this pump has been performing well so far. They are hopeful that it will continue to last for a long time.

Not only does this pump look great, but it is also easy to set up and was shipped quickly. The customer has been using it for a month now and has experienced no issues at all.
