Maintaining a proper swimming pool water level is important when it comes to skimmers to ensure that they are working properly. Since the skimmer helps keep your pool clear from debris by pulling them in before they sink to the bottom, it is best to make sure you have the right amount of water in your swimming pool.
The level at which the swimming pool skimmers operate best is between one third and one half of the way up the opening of the pool skimmer. If the level is too high, the water moving into the skimmer will be going too slow and the debris may pass by the opening without being pulled in. If the pool water is so high that it covers the skimmer opening completely, floating debris can’t get in.
If the water is too low the skimmer can bottom out, thereby sucking air into the system which can result in losing the prime and possibly result in burning up your swim pool filter pump motor. With low water levels, the skimmer won’t be able to properly catch debris and it will make a noise caused be the air flow. This can cause your skimmer’s lifespan to decrease, and you will also need to restart the system.
If your swimming pool filter system requires backwashing, be sure to add water before backwashing and vacuuming the pool because this will lower the water level.
