Water outlets are any pool opening where water goes out of the pool for circulation, some examples are:. It is critical that the skimmer be in good operating condition and functioning properly; the skimmer basket must be in place at all times and free from damage and the skimmer weir, flap in the throat of the skimmer that maximizes skimming action , is in place and working freely. The skimmer is the place we recommend that you use to vacuum the pool to insure any large debris that may be vacuumed up is caught in the skimmer basket thus avoiding a potential plugged circulation line. Main Drain: The main drain is typically located at the deepest point of the pool and is used to lower the water level, however its primary purpose is to circulate water from the bottom of the pool. Some residential pools do not have main drains, instead relying on a deep water outlet to drain the pool and for extra circulation.

Pool Troubleshooting: Bottom Drain Clogged
Swimming pool water can get bad over the years — so bad that chemicals lose their effectiveness. To drain and refill your swimming pool, start by renting a submersible sump pump from a home improvement store, if you don't already have one. Then, you should connect the clean out pipe from the sump pump to the sewer, if your municipality allows that amount of drainage, or direct the water to irrigate your plants. After the pool is drained with the sump pump, clean the pool with a hose and scrub brush. Finally, refill the pool using 1 or 2 hoses and wait for the water to settle before adding chemicals.
We've already seen that the water in a swimming pool needs to circulate through a filtering system, to remove dirt and debris. During normal operation, water flows to the filtering system through two or more main drains at the bottom of the pool and multiple skimmer drains around the top of the pool. The main drains are usually located on the lowest point in the pool, so the entire pool surface slants toward them. Most of the dirt and debris that sinks exits the pool through these drains.
