If you believe that the most important part of a swimming pool is, well, the part that holds the water, then you can think again. The real heart of any swimming pool is the sand filter pump, which maintains the water as clear as crystal. In this way, when combined with other features such as the disinfectant (which kills the bacteria and smaller organisms), the water needn’t be changed on a daily basis.
And while you can purchase new sand filter pumps from us, here is the most important thing you need to do in order to prolong the life of your already bought pump: just backwash it from time to time, in order to remove all the impurities gathered in it.
This isn’t such a difficult job and you can do it yourself, without the help of any kind of professional – any kind of sand filter pump is low maintenance, from this point of view. Find more info.
There are two types of backwashing which can be used in order to clear the impurities and prolong the life of the pump – and these types of backwashing depend on the valve the pump uses. However, before beginning, you should make sure that the pump is turned off.
If the pump has a side valve, unlock the T handle and put the air bleeder in the open position. With a hose, start pumping water in it – it takes about 3 minutes until the water becomes crystal clear. However, if this doesn’t happen from the first try, repeat the process. Once the water has become clear again, turn the T handle in its initial position and start the pump. The time needed for cleaning the pump depends on the dimension of the pool.
But how can you know that the impurities have been released, other than the quality of the water? Well, if the pressure is high, after turning the T handle to its initial position, then there are still impurities which block the water – so the process needs to be repeated. If the water pressure is low, then the sand filter pump is already clean and you can use the pool once again.
The other type of backwashing comes when the pool has a multivalve pump system. In this case, the T handle should again be turned and the water should again flow. Afterwards, the valve should be turned in a different position, so that the backwashing may happen.
You can realize if you were successful by either verifying visually the clarity of the water, or by either verifying the pressure of the water. Once the pump was cleaned by all its impurities, you can turn the T handle and the valve in their initial positions.
As said, these types of pumps are low maintenance – however, they do have a life expectancy of their own. In such cases, it may be useless to try backwashing. So, if the pressure is still high no matter how many times you tried backwashing, you might just have to replace the sand from thesand filter pump or even the pump itself. In such cases, rest assured – it will be quite a small investment.
