Two Reasons You Need A Main Drain In Your Above Ground Pool!
What is a main drain? A main drain is a suction port installed in the center of the bottom of your pool. A line is plumbed into the drain and ran back to the pool pump. Having a main drain in your above ground pool can be an extremely beneficial thing to have. Two of the most beneficial aspects of a main drain are discussed below.
Having a main drain installed in your above ground pool will greatly increase the water circulation in your pool. Most above grounds are installed with just the skimmer to act as the suction side of the filter system. This means that the water pulled into the pump will come from the water that enters the skimmer. The skimmer is located at the top of the water level, so it will only pull water from the top of the pool.
Installing a main drain will allow you to pull water from the bottom level of the pool. So instead of just having the skimmer pulling from the top, now you can pull water from the top and bottom of the pool. This allows for better water circulation and helps with the overall maintenance aspects of the pool.
We have found installing a main drain will greatly reduce the time you spend vacuuming your pool. Dirt and debris will naturally end up on the bottom of the pool. With the main drain pulling water from the bottom of the pool, a great deal of dirt and smaller debris will be pulled from the pool to the filter system.
With larger debris such as leaves, they will end up either on or near the main drain. Since they are in one place they are easier to clean up.
In some instances pool owners almost never vacuum their pool. They find that with normal swimming and the main drain working, most of the dirt will be filtered off the bottom of the pool automatically.
There is no doubt that a main drain is a great thing to have on your above ground pool. With the added circulation your water will stay cleaner with less chemical use. Add in the benefit of less vacuuming and you have a winner!
