Identifying Common Pool Skimmer Problems

Your pool's filtration system relies on a few key components working together at all times. When one of these components fails to accomplish a certain task, you may start to notice a decline in the water quality in your swimming pool. Before water can be filtered, the pool pump must move it out of the pool and through the pool's filtration system. Pool water begins its journey to the filter and pool heater by running through a skimmer intake. Your pool may have multiple skimmers, but each one accomplishes essentially the same task at all times while the pump is running. Water is sucked into the skimmer, where large floating debris like leaves and twigs are filtered by the skimmer basket. Once the water enters the skimmer, it is transferred through pipes to your filter. If anything happens to impede the water passage or prevent the skimmer from taking on water in the first place, it can lead to bigger problems with your pool's filtration and circulation.

If you do find that your skimmer is clear of debris, and still isn't able to properly circulate water to the filter, there are a few things you can check that may be the cause.

Consult Filter Pressure Gauge
Every pool filter features a pressure gauge of some kind, usually located at the top of the filter attached to the control mechanism. This pressure gauge is a good indicator of the status of your pool's filtration system. Typically, an ideal pressure reading will land at around 20psi, meaning there is an adequate amount of water being moved through the system by your pool pump. If this pressure rises, it is likely caused by a disruption of the constant water flow from the skimmer to the pump and filter, meaning there is a blockage in the pipe or skimmer itself. If the pressure lowers significantly, it means the water itself is not reaching the pump at an adequate rate, which is likely due to a leak in the pool plumbing which will need to be immediately fixed. If you have access to the plumbing connections of your pool skimmer intake, turn off your pump and take a look to see if there is any leaking water coming from the pipe or connection to the skimmer.

Insufficient Water Level
A skimmer intake requires the pool water to remain at a certain height at all times to function properly. Typically, water should rise to cover about 2/3rds of the skimmer opening. This will ensure water is drawn in at an adequate rate to keep up with the pump. It will also prevent any air from being sucked in by the skimmer intake, which can lead to air pockets in your pool pump and plumbing, which have the potential to damage your pipes or the pump itself. If the water level drops below one half of the skimmer opening, it is important to raise the water level immediately. If you notice your pool water level is dropping frequently, you might want to contact a professional to inspect and repair any leaks in your pool plumbing.


Since the filtration cycle of your pool water starts with the skimmer intake, it is important to ensure this component of your pool equipment is well maintained at all times. You should always regularly clear out your skimmer basket, and be on the lookout for any drops or rises in water pressure as well as low water levels around your skimmer intake opening.

Pool and Spa Main Drain Repairs

While it is often referred to as a main drain, the main drain in your pool or spa doesn't actually let you empty your pool or spa. Instead, this 'drain' allows for water to be pumped out of the pool and through the plumbing system. Water that exits through the main drain is often sent through a filtration system that is controlled by your pool or spa pump and returned via your pool or spa jets or inlets. If something should go wrong with your pool or spa main drain such as a clog or cracked pipe, this can lead to some major inefficiencies with the rest of your pool's equipment. Since the main drain is usually located at the lowest point of a pool or spa, it may not often get as much notice when something goes wrong. To help you determine when it's time to call for pool and spa main drain repairs, take a look at some examples of common issues listed below. Increased Suction Sometimes a main drain will remove water at an accelerated rate because another one

Tree Root Problems With My Pool, What Do I Need To Do?

Tree Root Problems With My Pool, What Do I Need To Do? This truly is a very extreme picture of damage tree roots can do to your pool, your deck, and your plumbing! Most of the time, the damage is much more subtle.   You might have a higher water bill (roots cause leaks).   You might notice that your salt cell can’t keep up with the chemistry (leaks caused by roots have the effect of taking the chemicals with the water running out)   We have had tree roots undermine and break up concrete pool decks, we’ve also seen roots come right through the pool walls, skimmers, tile, coping, and actually grow down the plumbing lines. I swear that some tree roots can "smell" the water in the pool, and make a beeline for it, stretching it's branches out until it pokes a hole, and busts up the floor or walls of your pool.   Usually you will notice something is “strange” long before it becomes this severe.   The first warning you may have is that your pool starts lea

Cleaning vs Replacing Waterline Tiles

A great looking swimming pool is always a positive feature on any property. Like a fresh cut lawn or a newly painted house, a pristine swimming pool is an eye-catching feature that will improve the overall appearance of any yard. Over time however, certain parts of your pool's appearance may start to decline. Waterline tiles are often prone to some type of deterioration over time. In many cases, proper pool care and regular cleaning can help maintain your pool surfaces, but eventually you may need to replace your waterline tiles entirely. To help you determine when its time to replace or simply clean and/or repair the waterline tiles in your pool, take a look at the helpful tips written below. Sun Damage Over time, waterline tiles exposed to direct sunlight will start to fade. While some tiles are more resilient against sun damage, eventually the regular exposure to sunlight will give your waterline tiles a bleached and faded appearance. Not only do sun damaged tiles look
