In this case, we are going to have a look at the filter cartridge you use in cleaning water in your swimming pool.

The first step is collecting all the relevant tool s that you will need for the job and turning off the flow of water.

After that, remove the pleated filter cartridge from the place where you had made the installation.

It will probably have a cover or a canister to protect it from external damages.

Remove the cover so that the filter cartridge can be exposed and easy to access.

Remove the filter cartridge from the canister in case it was attached to it and inspect the level of dirt on it.

Using a garden hose pipe, rinse any form of debris that might be on the pleated filter cartridge before it dries up.

If it is allowed to dry, the debris may settle on the filter cartridge making it difficult to clean later.

You can now place the filters in bright sunlight so that they can dry up thoroughly.

Sunlight has algaecide properties that are very important in the cleaning process of the filter cartridges.

After that, remove the loose particles from the filter using an air compressor or simply shaking.

You can also remove the loose particles from the cartridge by tapping it against a surface or using a brush.

Cleaning one pleated filter cartridge is not economical so you will collect a number of cartridges and clean them together.

Place the cartridges in a bucket before bringing in and pouring the cleaning agent into the bucket.

You will use a chlorinator to clean the cartridges so prepare the solution well.

The solution will require “one-part pool chlorinator to six parts water” for the soaking of the filters.

Pour the solution in the bucket and cover the lid to allow it to soak properly.

Soaking the filters will kill all the micro-organisms and break down any form of organic contaminants on the cartridge.

You will soak the cartridges in the solution for a period of three to five days to get the best results.

Remove the pleated filter cartridges from the solution and rinse in clean and fresh water.

Hang the filters in sunlight and allow them to dry thoroughly, then, shake off any dust particles on the cartridge.

After that, soak the filters again in water and muriatic acid solution to dissolve minerals in the filter media.

Immerse the cartridges in the solution and ensure that the solution is not bubbling any more before rinsing it in water.

Bubbling is the indication that the solution is reacting with the acids thus proof that it is cleaning.

Use plenty of fresh water to help you in rinsing the cartridges.

Allow the cartridge to dry up then shake off any dirt on it before reinstalling it to its normal position.

A Step-by-step Pleated Filter Cartridge Replacement Process

The process of filtration will require you to make certain adjustments to increase the efficiency of the device.

Filtration process

Among the changes, you will be making include the replacement of the pleated filter cartridge.

Continue reading as I explain to you the process of replacing a pleated filter cartridge.

The wide surface area of the pleated filter cartridge makes it have a longer life serving as a filter.

The manufacturers make it in such a way that you can wash and use it again.

At some point, you will have to replace the pleated filter cartridge especially if it is damaged.

The process of replacing the pleated filter cartridge will depend on the application you were using it for.

In this case, I will take you through the process of restoring a pleated filter cartridge you use in your houses.

First, you will have to prepare well for the whole process of doing replacements.

You can do this by having a checklist of all the materials you will need as you replace the filter cartridge.

Go through the list checking out all the elements that you have in place till you confirm everything is in order.

The preparations will include turning off all the waterways in the house preventing the flow of water out of proportion.

The materials you are to have at hand include a filter wrench, strap wrench, replacement filters, silicon grease among others.

Do not forget to have a replacement O-ring, Teflon tape, a bucket and some rags for cleaning in case of a spill.

The second step is usually turning off the water and releasing the pressure within the system and the pipes.

Fill up a bucket or a sink with water which you will use in rinsing the other parts of the cartridge you are replacing.

The third step will involve opening the canister where the canister is using the filter wrench to expose the filter.

Many have had problems opening the canister but when it is done carefully, it will open up easily.

Make sure you release the water pressure in the canister that may make it very tight and difficult to open.

After opening the canister, you will expose the pleated filter cartridge thus making the work of replacements easier.

Inspect the old cartridge making sure that it requires replacements or not because others may need cleaning.

You will clean the canister to rid it of the impurities that may accumulate during the filtration process.

Apart from that, make sure that the cartridge is worn out and will require replacements.

If not, will clean the cartridge well and put it back to its original position for further use.

If it is worn out and you cannot use it again, you will have to replace it with another cartridge.

While you are at it, scrutinize the O-ring and replace it according to the right specifications.

The O-ring is unique because it is the seal between the filter and canister helping in the prevention of licks.

Be careful when inspecting the O-ring and try not to stretch it because you might end up using it again.

After that, put the plumber tape around the threads surrounding the neck of the canister that will contain the cartridge.

The process is not as important, but it can help you especially if you are running into accidental leaks.

Make sure you do it well the first time because you will have to repeat the whole process if it fails.

Before you put back the canister, you should replace the old cartridge with the new cartridge if need be.

Perfectly center the cartridge in its normal place making it easier for you to put back and to increase its functionality.

After that, put back the canister to its original position and tighten using your hands making sure it sticks well.

Finally, pressurize the whole system again so as to enable the whole system to run well.

After that, you can open up the water again to allow it to flow through the filters.

As the water flows through the filter, it becomes clean and therefore good for domestic use.
