How does a pool weir work




















Not quite true. Too low and you start to get gurgling sounds which are telling you that your pump is working way too hard at trying to keep the water flowing. Too high of a water level will still let water flow but cuts down on the efficiency of the skimming action that the weir helps to provide. In fact, allow your water to exceed the top of the skimmer opening and you will prevent most of the surface debris from ever entering the skimmer, since water will be drawn in from below the surface.

At this point the pool will still circulate and filter, but the skimming effect will be lost. On to the skimmer basket! OK, so how often do you check and empty your skimmer basket? It takes seconds to do but many of us miss this important detail. In fact the same principle applies to cleaning the pump basket as well. A basket full of debris greatly reduces water flow, adds strain to the pump, and hinders adequate filtration. Although it's generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time.

A proactive, productive and energy-saving maintenance activity is to remove the debris floating on the pool surface with a hand-held skimmer. A skimmer is a necessary element of keeping a pool clean. The skimmer sits at the waterline and catches leaves, bugs and trash so they do not clog the filter. Skimmers with a second hole help keep the pump from running dry if the water level is unstable. Look for excessive air in the pump or a lot of air in the filter when you open the air bleed at the top.

As for the basket floating , just use a rock to keep it down. The 'flying saucer' is to protect your plumbing in case your water level gets too low.

Add a few drops of red food coloring into the water at the skimmer box and watch to see if the water is flowing. A weir is a small barrier that is built across a stream or river to raise the water level slightly on the upstream side, and is essentially a small-scale dam. Weirs allow for water to pool behind them, while still allowing water to flow steadily over top of the weir itself. Probably the most important thing this skimmer float valve does is regulate how much circulation gets split between the main drain and skimmer.

If the water gets low in the Pool The Float inside will fall down and shut of the skimmer and only pull water from the drain. Look for a part number on the underside of the skimmer lid or on the rim of the skimmer basket. The part numbers will help us identify the correct skimmer. When discussing skimmers in regard to your pools and spas , we usually use the term to refer to two different things: A mesh basket attached to a utility pole used for scooping up surface debris. The devices installed at the surface of the pool to help with circulation and cleaning of the pool and spa.

Pool skimmers are important for both above ground and inground pools and are installed near the surface of your pool to catch floating debris before it sinks to the bottom of your pool.

The most common pool skimmer parts include skimmer baskets, skimmer cover, and the skimmer weir flap over which water flows.

During cleaning, a proper inspection of the weir, basket and lid condition should take place. If there is any damage or improper function, the skimmer should be repaired. The skimmer serves a very important role in keeping the pool clean and protecting the equipment. Start service today. Facebook Instagram. A skimmer also provides a conveniently located suction line for vacuuming.

Many pool circulating systems have at least two surface skimmers connected to the pump. While most skimmers are built into the pool, some types are designed to hang on the side. Most are molded, one-piece plastic units. Older pools often have built-in-place concrete skimmers. For the most effective collection of debris, there should be one skimmer for approximately every square feet of pool surface.

Newer models include floating automatic or robotic skimmers, some of which are solar-powered. This kind of skimmer connects to an automatic pool cleaner vacuum , while the solar model floats independently along the surface of the pool, collecting all types of debris. Both models are designed to keep a pool cleaner, cut down on your time and energy spent maintaining the pool, and save money and energy by not putting so much strain on the pump. Most skimmers consist of a tank with a projecting throat-like device on its upper side.

There, a self-adjusting weir or floating weir performs the skimming action by regulating the amount of water that enters the skimmer. Because it adjusts to allow only a thin sheet of water to spill over, velocity, not volume, is the key to good skimming action. It must have an equalizer line—a pipe that extends from the bottom of the skimmer about 12 to 18 inches through the pool wall into the water—to prevent air from being sucked into the system when the water level is low.
