How a pool purifier works
Operating process of a pool treatment plant:
- The operating process of a pool purifier consists of: suck the water through the skimmers, drains or pool cleaners through the self-priming pump.
- The water reaches the filter, which is the mechanism for cleaning and purifying the water, where dirt is retained.
- Clean water is returned to the pool.
- When we have filtered the entire amount of water contained in the glass, it is considered that we have completed a cycle.-
- The pool must be filtered through filtration cycles.
- Above all, it is essential to start the pool filtration during the sunniest and hottest hours.
- From when the water temperature is higher than 28ºC, it must be filtered continuously.

How to install pool filter
Steps for installing a pool filter
STEP 1 Purifier installation: Purifier base
- The first step is to place the base of the purifier on the ground and fit it with the sand tank. (tank support).
- This entire procedure is carried out with two plastic anchors.
- Using the size 13 open-end wrench we will also secure the pump to the support with screws.
- Next, if it exists in the pool purifier model purchased, we install the pool pre-filter by screwing it onto the pool pump.
STEP 2 Purification installation: Crepina
- Then, the crepine is mounted which make up the entire interior part of the pool treatment plant.
- The main function of the nozzle is to facilitate the entry of water so that it can be filtered and at the same time not allow it to retreat once inside.
STEP 3 Purification installation: We fill the tank
- In this step, it is very important to remember that before filling the pool purifier tank we must cover the nozzle tube.
- Next, we fill the pool purifier with sand or with pool glass (again we recommend that glass is the option we recommend).
- Reminder: The filling of the filter load is distributed evenly inside the container, leaving the last 15 centimeters empty until the closure.
- Next, we uncover the nozzle tube.
STEP 4 Purification installation: Selector valve
- We mount the selector valve placing a gasket to prevent water from escaping.
- Check that the valve fits with the nozzle.
- Finally, we secure the valve to the tank with the clamp.
STEP 5 Purification installation: Manometer and air purge
- We remove the plastic cap located on one of the sides of the valve and we installed the pressure gauge and air bleed there.
STEP 6 Purification installation: Water pipes
- Firstly We connect the pipe that connects the pool pump to the purifier.
- We fix the respective clamps and tighten them.
- We connect the pool pipes to the pump and the filter to the pool glass.
Step 7 Debugging installation: Local
- We secure all connections with a metal clamp using Teflon tape to properly seal pipe threads.
Monoblock filtration equipment installation video
Next, you can watch a video showing the installation of a monoblock filtration unit and also explaining its operation.
Where to place a pool purifier
Indicated location for pool purification installation (pool filter): site with good ventilation, avoid rain, avoid low temperatures, avoid humidity and install it with a flat and firm base.
Next, place the pool strategically, that is, according to the surroundings., since if there are trees, natural grass, sand in the vicinity of the pool... all these elements will fall into the pool causing alterations in the pool water and generating more maintenance.
Pool filter maintenance
The maintenance of the pool purifier will be the key in order to extend its life and to ensure clean pool water.
Likewise, we suggest you read of our pool maintenance blog and especially the entrance of How to clean a pool.
Sporadic checks for the maintenance of pool filters
Sporadic checks for proper functioning of the pool purifier
- Verify that there are no losses due to any breakage
- Verify that no sand accumulation at the bottom of the pool.
- Check that at the top of the tank the sand is not oily.
- Examine that in the filter tank there are no cracks.
- Examine the diffuser status.
- Check the status of the vertical tube.
- Check that when we turn off the pump the filter indicator does not stay at zero.
- Check that There is no obstruction before or after the filter.
Pool purifier precautions
Precautions and actions for proper functioning of the pool purifier:
- Approximately every 3 years (depending on many variables) the sand in the filter should be changed since it rounds, clumps, etc. and retains much fewer particles. We recommend consulting the pool sand purifier for further clarification.
- As minimum, Once a year, the filter system must be disinfected. so that it does not calcify and the sand does not turn into sandstone.
- Maintain the level of water from the pool glass ¾ of the skimmer.
- Check water parameters regularly.
- The hose we use has to be the diameter of the filter inlet/outlet pipe.
- Therefore, it is necessary regularly clean the pre-filter basket.
Reduce pool filter pressure
The filters decontaminate the pool from impurities. As the water passes through the body of the filter, the dirt is removed and the water is returned clean and ready to enjoy.
But Sometimes the air stays in certain parts of the pool filter and pressure builds up.
In addition, it is important that the filter does not have air so that the water pressure is always correct.
Most common circumstance why the pool filter has air
The most common case in which the filter can catch air is that the pump or circuit has caught air.
In that case you will see that the pump is empty, it will make a different noise than normal and you will also see a bubble in the filter.
Steps to lower pressure accumulated in the pool filter
- Al activate the relief valve In its upper part, the air leaves slowly and the excess pressure is corrected.
- Then, filter operation is activated in its configuration and check its pressure with the pressure gauge at the standard system pressure values, depending on the size of the pool.
- The filter is operated and the valve is opened to bleed the air, you can tell that it is fulfilled when there is a hissing sound from the air coming out of the valve.
- Then, The water comes out of the valve and is closed to read the indicator pressure with the filter working.
- When the pressure has not yet equalized, the discharge valve is opened again to eliminate any air left in the filter.
