Pool filtration, what should you know about them?
Customers often ask us about pool pumps - among other things, what are the differences, how to replace them and what will be their optimal performance. We have prepared a clear guide especially for you, in which we answer these and other questions.
- The filter pump is one of the most important pool accessories. It is important that she works several hours each day.
- How does it work? The water in the pool circulates in a closed system: one hose enters the pump where it is cleaned, while the other hose allows it to return to the tank.
- The pump needs electricity to run, so for safety before using the pool, make sure it has been turned off before.
- Frame and expansion garden pools are equipped with holes in which the pump is mounted. On the other hand, inflatable models do not have this option.
- Filter pumps are available in two versions: with a paper filter or with a sand filter.
Paper filter pump or sand pump? What's the difference?
Paper filter pumps are devices that are cheaper than their sand counterparts. They filter the water using replaceable paper filter inserts. They do this efficiently, but the paper filters clog relatively quickly, which means they need to be replaced often. It compensates for the mentioned affordable price.
When the filter needs to be replaced or cleaned:
- Disconnect it from the power source
- Remove the case ring and cover.
- Pull out the filter
- Rinse the dirt and wash the pad under running water.
- If the filter is damaged, replace it
- Paper filters don't last long: they range from a week to about a month.
Sand filter pumps are by far the most durable and efficient solution that - given the price higher than paper filter pumps - to the user pays off.
Filtration in this type of pump takes place thanks to quartz sand, through which water flows under pressure. Thanks to its properties, it effectively stops any pollution, including the smallest ones, which the paper filter cannot handle. Another advantage over a pump with a paper filter is that the sand filter does not clog and you have to change it every 2-3 seasons.
Remember that proper pump operation requires systematic equipment maintenance, so the filter should be cleaned regularly. It is best to do it about once every 1-2 weeks. How? It's very simple - just rinse the filter. It is also necessary to do this before storing the pool after the summer season.
However, it should be noted that the life of the filter also depends on the pH level of the water in your pool, so you should pay attention to it as well.
So which one to choose?
More and more pools are equipped with a filter. However, if you need to buy the equipment separately, you should first pay attention to the volume of your pool and the diameter of its outlets. The outlets are usually 32 and 38 mm. Therefore, we choose a pump with a hose and a thread of the same or larger diameter as the hole in the pool to ensure free flow. In the latter case, you will also need a 38-32 mm reducer.
Pump manufacturers usually describe in the parameters the range of capacities with which a given pump should operate without error. It is also recommended that the upper limit of this value be at least 10% greater than the actual pool volume .
At least once a day , all pool water should flow through the filter. A pump that is too weak clears the water much more slowly than the proposed model, so the whole process can take a long time. In this case, it is also possible that the pump will not be able to draw water from more distant parts of the pool and will only pump water in the immediate vicinity of the outlet, thus not being able to clean the entire tank.
