How Pool Plumbing Works
Learn how pool plumbing works. Here are the parts of your pool’s plumbing. A main drain is similar to a skimmer, but instead of actively sucking in water, it draws water through a pump and filter. The water then passes through a filtration system, which cleans it of microscopic debris. The pipes then return water to the pool through multiple inlets. Generally, a pool has two main drains, while a small one may only have one. A main drain is located at the deepest point of the pool. how pool plumbing works
A three-port valve connects the pool’s suction line with the spa’s return line. The diverter will determine which line is connected to the stem, which continues to pump water back to the pool, and which line goes to the return. The other two arms of the valve connect with the skimmer and filter, and they may also be used for step jets, fountains, or water features. The diverter can be set so that water is evenly split between the two arms.
A pressure-relief valve, or P-V, prevents water from draining out of your pool. Groundwater can build up under your pool and exert tremendous upward pressure, known as hydrostatic pressure, which can crack your pool. A one-way valve can relieve this pressure. If you are using one, make sure to check the groundwater in your area first to prevent it from affecting your pool. A one-way valve is especially important if you live in a rainy area or suspect that groundwater is nearby.
A main drain is the most common cause of drownings in swimming pools. These drains provide a high suction force that can easily drown small swimmers. They can even be a hazard to small children. Luckily, newer pools are designed with safety in mind, and most have two main drains. These main drains are often accompanied by a water level regulator, which cuts the suction power in half.
The main drain should be plugged before closing your pool for the winter. If not, water will still leak into the system even when the pump is turned off. The circulation system in a pool depends on a considerable amount of suction, so cracks in the pipe could lead to serious problems. If not treated early, cracks can lead to a total burst. When this happens, you could end up with a pool that is unusable.
In addition to the main drain, you should also be aware of how the other parts of the plumbing system work. You can install automatic cleaners, or hire a professional to do the cleaning for you. Automatic cleaners, for example, will keep the walls and floors of your pool clean. Many users report positive results from using this type of pool equipment. The Blue Torrent MyBot Inground Robotic Cleaner is a good example of an automatic cleaning system.
In addition to plastic pipe, swimming pool plumbing may also be made of metal pipe. These are joined together by connection fittings. The plastic pipe is called the “male” and the male is attached to the female opening of the connection fitting. Connection fittings are made of plastic pipe called PVC, which has different strengths. Each PVC pipe has a schedule number; the higher the number, the stronger the pipe. Generally, pool plumbing is made of schedule 40 PVC.
