Needless to say, a pool vacuum employs the force (vacuum force) to clean the pool. The circulation pump generates vacuum and it is this vacuum that goes behind pulling water into the skimmer lines and also back to the pump as a result of negative pressure.
Wondering what effect does positive pressure have? Well, it is because of positive pressure itself that the water is pumped through the sand filter. Well, it doesn’t end there. Water gets conveyed back to the pool through the return lines as well.
Talking about the operation, the first step starts with filling the vacuum hose with water. Following this, the hose is fitted into the skimmer inlet. This gets the skimmer into action. It pulls the water through the vacuum tool. The dirt, debris, leaves, etc. get sucked up when the vacuum makes its way over the bottom as well as the sides of your pool.
You have nothing to worry about the collected debris as all of this is conveyed to the sand filter by following the path of the skimmer and the pump.
When you are vacuuming your pool with a sand filter, extra attention has to be paid to the settings. What you choose should depend on the amount of dirt present in your pool.
A filter option should be good to go if yours is a residential pool and a normal level of debris and dirt is to be addressed. When you choose this option, the vacuumed water is directed to the filter and then back to the pool using return lines. All the debris that’s collected by the vacuum is removed from the water by a bed of sand filtration media that’s present inside the filter. The fact that some amount of all the debris trapped might get accumulated on the sand filter cannot be overlooked, extra care has to be taken in this aspect as well. What you can do is perform backwashing here to get rid of any accumulated debris. Now, do not get worried about how to proceed with this. Just refer the manual that you are provided with. There, you’ll find all the steps to be followed. Following them step by step (without missing out on any) will help you deal with this. If your guide doesn’t mention anything regarding this, you can always take help from a professional or an expert.
Also, there are some cases when vacuuming a pool with a sand filter is not recommended. Some of them are when the pool is full of algae, a thick layer of debris is settled at the bottom, the pool has been unused for quite a long time, etc. So, for best possible results and to be sure whether the pool is in a condition to vacuum it using a sand filter, always consult an expert.
