The skimmer is the device that is mounted at the top of the wall of the pool that catches debris like leaves, bugs and oils off the surface of the water before they sink. It is the first line of defense against pool contaminants. This will be done through a small flap, called a weir, which controls how the water flows and allows only the surface layer to be extracted.
How Does a Skimmer Work?
When the pool pump is on, water is drawn from the pool into the skimmer. A barrier-type flap (the weir) allows the water (with floating debris) to flow into the basket and regulates the movement of the placed water. A removable basket inside the skimmer catches the debris, which makes cleaning the pool system easier and keeps the filters unclogged.
Types of Skimmers
There are different kinds of skimmers based on the type of pool or users' needs.
1. Wall-Mounted Skimmers
The most common type is a wall-mounted skimmer. They are integrated into the edge of a pool, with their opening being box-like. These skimmers use a weir mechanism that allows surface water to flow into a basket that collects debris. It can easily access the basket from the pool deck to clean.
2. Overflow and Infinity Skimmers
These systems have become common in contemporary pool designs. In an overflow system, water spills over the edge of a pool into a collection channel. The continuous line of water is not only an aesthetic but also an effective way of collecting debris from the surface of the water. But they can be trickier and more expensive to install.
3. Robotic and Floating Skimmers
Newer models of robotic skimmers have been developed that operate independently of boats, powered by batteries or solar energy. They navigate around the pool and automatically pick up debris. Similar to floating skimmers, it is ideal for those pools where it becomes tedious to do manual cleaning.
4. Manual Skimmer Nets
Simple but effective, a manual skimmer net is a hand-held device used to remove debris from the pool. While this type is ideal for small pools or spot cleaning, it necessitates constant labor by the pool proprietor.
Benefits of Using a Skimmer
Skimmers offer several benefits that aid in the maintenance of pool water quality and protecting pool equipment.
Enhanced Water Clarity
Skimmers help keep the water clear by removing leaves, bugs and other debris from the surface of the pool. Not only does clear water look good though, it is an indicator that the pool is well maintained.
Prolonged Equipment Life
Skimmers stop large debris from entering and clogging the pool pump and filter. This keeps the equipment running smoothly and for longer, decreasing the likelihood of expensive repairs or replacements.
Optimized Filtration Efficiency
Because skimmers capture debris before it gets to the filter, the pool’s filtration system operates more efficiently. It means the filters don’t have to work as hard, so they’re efficient and less likely to get clogged.
Improved Water Circulation
A functioning skimmer helps circulate the water. Circulation improves the distribution of chemicals used for sanitation and maintains balanced water qualities throughout the pool.
Energy Efficiency
Additionally, less work done by the pool pump is better in terms of energy efficiency, which is why skimmers help in this regard. A pump operating with less resistance will result in a lower power consumption, which over time, can add up to a significant cost saving on the electricity expenses.
Aesthetic and Safety Benefits
Clear water without floating debris is far more appealing and welcoming. Furthermore, a clean surface helps minimize the risk of slippery areas around the swimming pool, making the poolside safer.
Choosing the Right Skimmer
Different pools have different needs, so choose the skimmer wisely:
- Pool Type and Size: Larger pools or pools with more decorative shapes might need a built-in or robotic skimmer, while small or above-ground pools will be well serviced using a manual net or floating skimmer.
- Maintenance Preferences: Someone who wants low maintenance can choose a fully-automated or robotic pool, or a simpler wall-mounted unit.
- Aesthetics: Some modern pool designs will have an overflow or infinity system to create a seamless, continuous waterline. Standard wall-mounted skimmers may be the best ticket for the job with traditional designs.
- Budget and Long-Term Costs: Skimmers can have a higher purchase price, but they can be more cost-effective over time with reduced maintenance and energy consumption.
- Installation and Compatibility: Check whether the skimmer is compatible with the plumbing of the pool and its existing construction material (for instance, concrete, fiberglass, or vinyl).
Installation and Maintenance Tips
For a skimmer to function properly, it must be properly installed and serviced on a regular basis.
1. Professional Installation
Built-in systems work best with professional installation, as it’s important for the skimmer to be properly positioned and connected to the pool’s plumbing. Generally, it should be positioned approximately six (6) inches (15 cm) below the pool coping.
2. Regular Cleaning
The basket located inside the skimmer should be scrubbed at least once a day when it is being used heavily. Also, clearing out jammed debris can stop clogs that can cause the system to fail to operate optimally.
3. Inspecting Moving Parts
The weir (moving flap) and float mechanism should be checked regularly. This means that these parts must be clean and in working order so that the flow of water entering into that skimmer is regulated.
4. Monitoring Water Levels
For best effects, the water amount is suggested to be around half of the skimmer opening. Low and high water levels can impact how well the skimmer functions.
5. Seasonal Care
In regions with winterized pools, skimmers are drained or covered to prevent freeze damage. It protects the system and gives it the opportunity to work as well as possible when the pool is reopened.
Conclusion
Skimmers are an essential part of every pool maintenance system. They help in keeping the water clear, protecting pool pumps and filters, and improving pool circulation by removing debris from the surface of the water. This translates into energy savings and a longer lifespan for pool equipment.
The best type of skimmer for any pool varies based on the pool’s size and design as well as the preference of owner maintenance. Pool owners need to regularly maintain the system and properly sort out the installation, whether going with a wall-mounted skimmer or a fancy robotic system.
