Most pool owners prefer using the sand filter for water filtration as it has a compact design and lower acquisition costs. Anyone looking for an above-ground or permanently integrated filter system for the pool is well advised to use a sand pool filter. However, like any other pool filter system, a sand filter system has to be maintained regularly. And the most important thing in the maintenance of a sand filter system is backwashing. To backwash water, the pool discharge hose is the most essential tool you need.
Getting the best pool backwash hose helps get rid of the dirty build-up that may have accumulated in the filter easily and quickly, which is why in this post, we’ll be seeing what exactly the function of a backwash hose is, show you what’s the best pool backwash hose for you, and how to use it.
What Is a Pool Backwash Hose Used for?
The filter medium (quartz sand, Aqualoon, Fibalon, glass, etc.) of the filter system catches the dirt in the pool water. Over time, more and more dirt accumulates in the filter tank, as a result of which the water can flow increasingly poorly through the filter medium. This manifests itself in a decreasing circulation capacity and increasing pressure, which you can read on the pressure gauge. The backwashing process with the use of a backwash hose transports the dirt out of the filter system and loosens the filter medium by pushing the water through the filter tank in reverse, i.e. from below. You should backwash with a hose about once a week.
While backwashing with a hose, the direction of flow of the pool water is reversed, this cleans the filter material of the sand filter system. The backwash speed is a multiple of the normal filtration speed so that the filter material (e.g. quartz sand) is loosened and the dirt particles deposited in the filter bed are removed.
The backwash ensures that dirt particles escape from the filter system and that the filtration of the pool water can continue with constant performance. If the filter system is not backwashed regularly, this can lead to sticking and contamination of the filter material and ultimately to poor water quality.

Features to Choose the Best Backwash Hoses
Pool backwash hoses, also commonly called flat discharge hoses, backwash hoses, construction hose, pool pump hoses, or flat hoses, are perfect for discharging and backwashing swimming pool water with light chemicals. They can also be used for other industrial, agricultural, irrigation, mining, and construction liquids. Due to their versatile application and heavy-duty requirement, finding the best pool backwash hose may not be so easy. But by following our buying guide to the letter, you should be able to find the best pool backwash hose that can last for several years, based on the hose material, accessories provided, the size, and other criteria.
Material of construction and durability
The best-quality backwash hoses are constructed from heavy-duty PVC or vinyl and have continuous high tensile strength polyester fiber woven to provide reinforcement.
Because they will be handling large water flows, the hose needs to be very durable in its manufacturing design. This was a significant factor for us when selecting the products on our pool backwash hose reviews.
The most durable flat hoses in the industry are designed with heavy-duty materials to be suitable for residential, construction, industrial, and utility applications.
The problem with poor quality hoses isn’t usually with their material of construction. They withstand water pressure, chemical, acids, and other elements during their first uses. But after a few days or weeks of exposure to the sun, they start cracking, fading, and leaking. That’s why your new pool backwash hose must have a coating that is protective to harmful UV rays.
A discharge hose formulated with a UV protector can withstand outdoor conditions and will be ideal for use in swimming pools, spas, and other external use.
Weight & storage
Because of the length and thickness, backwash hoses are usually relatively heavy, between 3 to 10 pounds.
Nonetheless, this shouldn’t be a deal-breaker when purchasing. A heavy hose generally means it’s of high quality, something that should always take priority. When it comes to storage, it is better if the model has a flat design. Lay flat hoses allow easier storage, requiring very small storage space.
Fortunately, very little hose maintenance is required with these products. They are almost self-cleaning – clean water will pass through and discharge once it has done its job. Still, be sure to clean it of dirt and debris before storing it.
Length and diameter
The length and diameter of the pool hose chosen are always dependent on the application and the distance of the pool filter pump to the sewer system. Generally, backwash hoses are designed in 25, 50, and 100 feet long. So, measure the length you need and choose accordingly.
The diameter of pool backwash hoses is also usually between 1.5 to 2 inches. However, you can also find one-inch, three-quarter-inch, and five-eighth-inch pool hoses. Again, the choice here depends on the size of your hose adapter. But the standard diameter is 2 inches.
Although most of the hoses are quite durable, it is always advisable to choose one with warranty coverage just in case something goes wrong. The warranty coverage gives you some confidence in the product’s reliability, showing you that the manufacturer believes in the quality of manufacturing of the hose. The best pool hoses come with 1 to 2 years of full warranty coverage for worry-free use.
Commonly Asked Questions
What size backwash hose do I need?
The size of your backwash hose will depend on your PVC pipe size, pool filter outlet, and hose adapter. So, ensure you measure before purchasing. On the market, you’ll find 1.5 to 2 inches of hose diameter. The distance of the swimming pool filter pump to the sewer should also determine the hose length. The most common are 50 feet but you can find 100-foot long hoses.
How to measure pool backwash hose?
You can know the diameter of your backwash hose or know the size of the hose you need. You only need to measure the distance across the opening of your hose adapter, pipe opening, or the hose opening with a ruler. Standard pool filter outlets measure around 1.5 to 2 inches.
How to install pool backwash hose?
To install your backwash hose, you need to turn off the swimming pool filter pump. Then, attach a suitable hose to the backwash opening of the multi-way valve and place it, for example, in the sewer (attention: if applicable, observe local regulations for the disposal of pool water!). Set the lever of your multi-way valve to backwash. Switch on the filter pump for approximately 5-10 minutes. Then, turn off the filter pump. Set the multi-way valve to rinse. Switch on the pump for about one minute. Turn off the filter pump again and set the multi-way valve to filter.
If you want to enjoy your pool for a long time and cool off in crystal clear water in your garden in summer, you should ensure that the pool filter system works properly. Pool maintenance includes regular backwashing (at least once a week. However, there’s no backwashing without a good pool backwash hose.
The process loosens the filter material and detaches the dirt particles from the quartz sand. The water running off in the opposite direction of flow, picks up the dirt particles and finally ensures the filter material is cleaned.
