Best Sump Pump Discharge Hose Review in 2021

Discharge hoses for sump pumps are mostly used to discharge water out of the sump pit basement to a safe location outside. Since these hose pipes are bigger than a normal garden hose, they can move a lot of water faster.

If you want your sump pump to perform and pump out water as the manufacturer intended, you will need to use the best sump pump discharge hose. Most sump pumps are designed to use 1-ΒΌ-inch to 2-inch discharge hoses.

The length of the hose starts from 24-ft and can go all the way up to 96 ft. Normally, you will see two types of discharge hoses. There are hoses that are corrugated, and some have a lie-flat design.

A discharge hose kit will include all the accessories needed for a proper installation. This means you will get barb adapters, couplings, hose clamps, and many more included in the kit.

Whether you want to empty the pool or pump out excess water from one place to another, you will need a heavy-duty sump pump discharge hose.

Top 5 Best Sump Pump Discharge Hose

Here are some of the best discharge hoses for a sump pump that should pump out water faster than your garden hose.

1. Superior Pump 99621 Lay-Flat Discharge Hose Kit

This is a 25-feet discharge hose kit from Superior Pump that is designed to work with most utility pumps and sump pumps. If you have a pump that has a 1-1/2 in. NPT or 1-1/4 in. NPT discharge size, you can easily connect this hose to your pump and discharge water.

It is a four-piece kit that includes a 25-ft hose which has a lay-flat design, a hose clam that has a high-quality stainless-steel construction, a thermoplastic constructed coupling adapter, and a 1-1/4 in. NPT adapter. Both of the adapters are male adapters, so you will have to buy two female adapters separately.

Let’s talk about the hose design for a moment. This hose is more of a temporary connection that is ideal for everyday pumping jobs. But you cannot use it as a permanent discharge pipe. However, this gets the job done when you want to have a hose on hand in case of an emergency.

The hose itself is 25 feet long and lets you direct the water to a safe spot outside of your basement. When you are done with it, you can easily roll up the hose for compact storage. You can also make different adapters on your own to connect with different sump and utility pumps.


  • Reinforced PVC constructed hose
  • Lay flat design for easy storage
  • Thermoplastic constructed adapters
  • High-quality stainless steel hose clamp


  • It doesn’t come with female adapters

2. Red Lion 599304 Flexible Sump Pump Discharge Hose Kit

Red Lion is a brand that has been making and developing components that move water since 1935. When it comes to making hose kits for sump pumps, they have years of experience under their belt. Whether it is a utility pump or a sump pump, this discharge hose kit is designed to work with them all.

If you have a sump pump that has a discharge size of 1-1/2-inch FNPT or 1-1/4-inch FNPT, you can easily connect this hose. This polyethylene hose is 24-foot long and corrugated. As for the accessories, this kit includes a galvanized steel clamp and thread/barb adapters.

It is an ideal solution for pumping out water from the basement sump into a safe area away from the house. The hose diameter is 1-1/4″. Also, it comes with two adapters. There are two adapters, and one has 1.5″ NPT threads, and the other has 1.25″ NPT threads.

Both adapters have a barbed end that fits inside the hose. While it is good for a temporary solution, I wouldn’t recommend it for permanent use as the hose isn’t very durable. Only use it in case of an emergency. The composition of the hose is somewhat lightweight, but it works well.


  • Good for emergency pumping situations
  • Flexible, corrugated hose
  • Easy to connect to sump pumps
  • It comes with threaded and barbed adapters


  • Thin hose, not very durable

3. Little Giant SPDK Sump Pump Discharge Hose Kit

Up next, we have another discharge hose kit, and this time it is from Little Giant. Fun fact, both Red Lion and Little Giant have the same parent company. Before you get this one, keep in mind that this hose is only good for emergency situations. You can’t use it as a permanent discharge pipe.

Also, you cannot attach two hoses together because this kit doesn’t come with any attachment adapters. That being said, you can easily buy a rubber 1 1/4 attachment and connect two hoses to increase the hose length.

Also, the adapters that come with the holes will only fit sump pump outlets. This kit comes with a check valve, a good amount of fittings, and a hose clamp. Most of the negative reviews of this product came from people that bought the wrong product for the wrong pump.

The fittings must be adapted/modified to fit with a fitting. Also, the hose comes pre-segmented. This means you can cut the hose to a shorter length. The hose is stiff at first, but you can make it flexible after a minute of flexing.


  • Durable and sturdy hose
  • It fits well with additional adapters
  • Includes two barbed adapters
  • It won’t crack or leak anytime soon


  • Difficult to connect with some models of sump pumps

4. WAYNE 56171 1.5-Inch Sump Pump Discharge Hose

The Wayne discharge hose kit is undoubtedly the one you should take a closer look at if you’re looking to buy a discharge hose kit that’s designed to last you quite a while. You might want to take a closer look at this discharge hose if your sump pump didn’t come with one.

If you have a sump pump that has a 1-1/4 discharge tapping, you can use the clamps with the kit. As far as compatibility is concerned, there is nothing to worry about. Hose clamps are included with this pump and can easily be used to attach the hose.

It fits discharges measuring just 1-14 inches and is 24 feet in length. There is no way around this adapter since the kit includes one specifically for this size. If the sump pump is equipped with a discharge of 1-12 or 2 inches, it won’t work.

In terms of equipment, this kit contains pretty much everything you’d need to make use of it without making further adjustments. It is easy to adjust the tube’s shape to suit your needs, and there is no need to worry that it will break.


  • A sturdy hose that won’t break easily
  • 24-foot-long hose length
  • Works well with Wayne submersible water pump
  • A lot better than a garden hose


  • It only includes a 1-1/4″ adapter

It is a versatile hose that can be used to drain water from your pool and also clean wastewater from the filter. It is also very easy to connect and use. The hose connects easily to the filter’s backwash port, which is equipped with a tapered fitting.

Or you can use adapters to connect to your sump pump. Keep in mind that you will only get a hose clamp with purchase. You won’t get any adapters or check valves.

How To Pick The Right Sump Pump Discharge Hose?

Typical sump pumps include a built-in fitting that is designed for the intended discharge pipe size. This is usually 1.25″ or 1.5″ in diameter. PVC is commonly used for sump pump discharge tubes, so determining their interior diameter is important. It is important to keep this factor in mind when purchasing a discharge hose.

The outside pipes are likely to be 1.5 inches and 2 inches in diameter, respectively. In order for a sump pump to perform as intended, its discharge pipe must be of proper size. That is why you should use PVC pipes as adapters if you can’t fit a hose.

That being said, there are other factors to look out for if you want to pick the right sump pump discharge hose.


It’s very common for discharge hose kits to come with all the accessories needed for a complete installation. It is safe to say that you will get everything included in the box, from hose clamps to adapters.

However, these hose kits aren’t made to be universal. You can’t just buy a hose and assume it will fit every discharge size. The average residential sump pump comes with a discharge that is 1, 1-12, or 2 inches. Make sure you choose the right kind of hose for your pump.

Also, a lot of the time, you will have to buy additional male or female adapters for the hose to connect your pump. If you are familiar with handy tools and know a thing or two about plumbing, it shouldn’t be a big deal for you.

Hose Length

I would recommend considering your specific use case and application before you determine the hose length. For most normal applications, a 24 or 25-foot length should be more than enough. However, if your sump pump is installed in a location where a 24-foot hose won’t be enough, you will need a longer hose.

A problem with these discharge kits is that the hose isn’t very long. And if you need to extend the length, you will have to buy two of them and merge them together. A bigger or longer hose isn’t always better. A discharge hose that is too long might cause more problems down the road.

Since discharge hoses are more of a temporary solution, it is better to buy two just in case if you need to extend the hose length. Additionally, you can even find hoses that are 75 feet long.

Construction Material

Various materials are available for making discharge hoses, which is why choosing the perfect one can be a bit of a challenge. Polyethylene is the most common type of material that is used to make discharge hoses. You can also find hoses made from reinforced vinyl.

However, there are different hose materials that are suited for a more permanent solution. In that case, those hose pipes are somewhat difficult to move around.

Accordingly, the most significant difference between a flexible hose and a non-flexible hose is that some hoses offer some degree of freedom, but others do not.

It’s difficult to determine the durability of a product simply based on what’s used in its construction. Some hoses are best suited for occasional use, while others can be used continuously.

How To Replace Sump Pump Discharge Hose?

Sump pump hoses typically have a diameter of 1 1/2 inches. Threads run from one end of the hose to the sump pump body, while the other end is for draining. When you notice a leak on the hose, there are two options. You can either repair it or replace it.

If it is absolutely necessary, you can wrap a small piece of duct tape around the break just to keep the water flowing, but this is only a temporary fix. If you don’t want to go through all the troubles of repairing, or if the hose is beyond repair, you can buy another one. Here is how you can replace the sump pump discharge hose.

  1. First of all, you should choose a compatible discharge hose kit. Make sure it fits into your sump pump. If you don’t need a long hose, don’t go for it. Go with a standard size hose which is 25 foot and buy two of them.
  2. Your previous discharge tube is going to have a clamp on it. You should remove that first. Make sure the motor is turned off. To undo that clamp, you will need a flathead screwdriver.
  3. Once you undo the clamp, pull the hose using your hands. It might be a bit tight, but the hose will come right off if you twist it a little.
  4. Now, take out your new hose and install it just like the previous hose. Make sure it fits. If not, you will have to make some couplings using PVC pipes. There are plenty of guides online on how to make couplings using PVC pipes. Check them out.
  5. One thing you want to make sure when you put the clamp on is that it is on the smooth side. You should never put the clamp on the ribbed side because that can make a leak. Also, push the hose down as far as possible in order to create a secure fit.
  6. If you want to increase the hose length, do so before you install the hose. There will be points on the hose where you can cut the pipe to make it shorter.

Frequently Asked Questions

1. Can you use a garden hose on a sump pump?

Yes. But it will exert a lot of pressure on your pump because a garden hose is usually smaller. Too small a discharge hose causes major problems.

Reduced pump performance and efficiency result from discharge pipes that are smaller than recommended.

Due to the small size of the pipe and the increased friction, the pump cannot push its rated volume of water. The resulting backpressure makes the job even more challenging. Basically, stay away from garden hoses.

In addition to reducing the pump’s life, undersized discharge tubing will make it run longer each time the pump starts. This can also decrease the overall lifespan of the pump.

There are exceptions when it comes to smaller pumps with garden hose adapters.

2. What do you do with a sump pump hose in the winter?

It is possible for the discharge hose to freeze when the temperatures drop. This may result in your pump turning on and the water having nowhere to go. A deadhead could result from this. The electric motor may break down or even catch fire if this happens.

During the winter months, make sure to check your system periodically. It is possible to damage your home when a sump pump freezes. Unplugging your pump should be your last step. In order to prevent a frozen pipe, you should install a discharge point that has a larger air gap at the top.

In the winter months, the larger hose is normally covered in snow. It costs around $10 to purchase 10 feet of the black drain hose. That is what you should use during winter.

With a piece of wire and a pipe clamp, fasten the larger hose and take out the smaller one.

Removing the hose from the sump pump’s discharge pipe is the best course of action when freezing weather is approaching your area. Wait until the weather becomes warmer before turning it on. A hose containing frozen water wouldn’t be usable until it thaws – and could be damaged as well.

3. Where should my sump pump discharge?

Sump pumps should be discharged as far away from your foundation as possible. At a minimum, there should be a distance of 10 feet. Typically, discharge pipes are attached to basement pipes by a flexible hose.

It should send any ejected water downhill, away from your foundation, far from your sump pump system. Your foundation will be flooded with water if your sump pump pumps out water to the ground near your house.

Final Words

The best sump pump discharge pipe is the one that comes ready to install out of the box. Also, make sure it is durable, comes with all the proper fittings, and has a larger diameter. As for the length, I will leave it up to you.

Most of the Discharge Hose Kits on this list come with everything for fast, easy installation. If you want a heavy-duty hose that has a larger inside diameter, I recommend you take a look at the Blue Devil 2-Inch Sump Pump Discharge Hose.

Just make sure to get the right barbed fittings. You can get them in any local hardware store. Although there is a bit of DIY process needed, the result is worth it.
