Step-by-Step Guide to Backwashing Your Pool Pump

If you have a swimming pool, then it's important to keep the pump clean. Not only does a clean pump run more efficiently, but it also helps to prevent clogs and other problems.

In this step-by-step guide, we will show you how to backwash your pool pump using simple steps that anyone can follow!

Benefits of Backwashing a Pool Pump

Pool maintenance can be an intimidating prospect for many homeowners, but there are certain practices that are easy to master and bring huge benefits. Backwashing a pool pump is one of these.

Not only does backwashing effectively remove dirt and debris from the water, it also helps extend the life of the filter system by breaking down particles which accumulate in the sand bed. This process is not time consuming at all, usually taking less than five minutes to complete, so even when there isn’t much time available it can be done quickly and efficiently.

Additionally, it is a simple practice that doesn’t require any expensive or specialized equipment – all you need is a garden hose and a few pool accessories. By performing regular backwashing, you can keep your pool clean and sparkling without significant effort or expense.

What is the Process?

Backwashing a pool pump is an important step in ensuring the filtration system runs effectively. Starting by turning the filter valve to “backwash”, one can then turn on the pool pump, allowing it to run for 3-5 minutes. This allows dirt and debris from the filter bed to be discharged through a waste line or into a grass area away from the pool.

Once backwashing completes, it’s recommended to clean out any debris from both the skimmer and strainer baskets in order for proper flow of water. To complete this process turn off the pump, switch the filter position back over to “filter”, and restart the equipment. Through following these steps those looking after a swimming pool can ensure their filtration equipment works at optimum efficiency.

Step-by-Step Guide to Backwashing Your Pool Pump

Turn Off The Power and Disconnect The Hose

Turning off the power and disconnecting the hose are simple yet important steps to remember when performing maintenance on any machine. Taking this precautionary measure can save time and money, as well as ensure the safety of yourself and anyone assisting in the operation.

It is also crucial to following manufacturer instructions for disassembly as detailed in user manuals. Taking all these precautions can help you be sure anything operating under pressure will remain safe and secure during any maintenance procedure.

Loosen the Filter Cap & Remove Basket or Grids

Before backwashing, the filter cap must be loosened to allow water to escape through the waste line. The basket or grids can then be removed after the cap is unscrewed and set aside until needed again. This step is important as it will ensure dirt and debris are effectively removed from the filter bed via backwashing.

Connect the Backwash Hose

Connecting a backwash hose is the next step in the process. This allows water to escape from the filter and direct it away from the pool area. The garden hose should be securely attached so that it won’t come loose while running. It’s also important to ensure any excess water is effectively discharged away from your pool.

Open the Valve to Allow Water to Flow Out

Open the filter valve to “backwash” and turn on the pump. This will allow dirt, debris and any loose particles from the sand bed to be discharged through the waste line or into a grassy area away from your pool. It is important to keep an eye on the level of water in the filter during this process as it should not exceed two-thirds of the maximum capacity.

Let the Water Flow Until it is Clean and Clear

Allow the water to flow from the filter until it is clean and clear. This should take around 3-5 minutes, but be careful not to run the pump for too long as this may cause damage to the equipment. Once done, turn off the power and close the valve.

Shut Off the Valve & Reattach The Filter Cap/Grids

Once the backwash is finished, shut off the valve and reattach the filter cap or grids. Make sure everything is secure before turning on the power and restarting the pump. It’s important to ensure that all parts are properly attached in order for your pool filtration system to operate effectively.

Turn On The Power and Recheck Connections

Finally, turn on the power and recheck all connections. Make sure that everything is secure and running correctly before leaving the area. This will ensure that everything runs safely and as expected, allowing you to enjoy a fully-operational filtration system.

Refill and Balance The Pool Water (optional)

If you have removed large amounts of water during the backwashing process, it’s important to refill and balance the pool water. This can be achieved by adding fresh water to the pool and using a chemical test kit to check that all levels are in balance before swimming again.


In conclusion, backwashing your pool pump is an important part of routine maintenance that should be done on a regular basis.

By ensuring all steps are followed correctly, you can ensure your filtration system operates at its optimal efficiency and help extend the life of the equipment.

Keeping a clean and healthy swimming pool requires diligence and attention to detail, but the results are well worth the effort!
