Why Is Dirt Coming Out Pool Jets? If dirt is returning to your pool through the return jets (sometimes known as eyeballs), this is another sign that something in your pool's system is wrong. It can be an indicator of broken laterals (in a sand filter) or that the filter needs backwashing.
if dirt is escaping back into the pool, it could be because the filter is dirty and clogged, which means it needs to be backwashed. When the pressure gauge rises eight to ten pounds per square inch (PSI) above it respective normal operating range, backwashing is necessary.
The most common problem is a cracked lateral, which is one of the perforated pipes at the bottom of the filter that catches water that has circulated through the sand. Whether it's a lateral, the standpipe, or a seal that is worn or broken, you can usually fix the filter yourself, but it may take a few hours.
There is most likely nothing wrong with your filter. You are simply vacuuming particles out of your pool that are too small to be caught by your filter (most likely a sand filter). Great news! There is a simple solution if you have a multiport valve on a sand or DE filter.
If most of the sand comes through the holes of the lateral, the sand is too small. Your pump may be too large or the sand level too high in the filter. When the filter is backwashing the water flow can cause the sand to rise high enough and overflow into the standpipe, which will allow the sand back into the pool.
If there has been a serious invasion of excess dirt and debris, you may also need to shock your pool. Vacuuming is recognized as the only way to remove sediment from the bottom of a pool.
Poor Filtration
If dirt is reappearing at the bottom of your swimming pool after you've vacuumed it your pool's filter may be working poorly. Pool filters often work poorly because they're in need of cleaning. If you have a sand filter for your pool you need to make sure that the sand is sharp and freshened up.
a 3 ft deep hole filled with soil is likely to settle considerably. Maybe even a good bit more than 6 or 8 inches, depending on how well (if any) it was compacted during the back filling. If you can stand it, wait a couple of months (preferably more) and let it settle really well.
These are likely caused by leaves, berries, algae, worms, dead animals, or other organic debris that will leave stains if allowed to settle on the pool surface. If they are not removed right away, they will sink down and begin to decay on your pool's floor. Fortunately, organic stains can be easy to remove.
Often, excess sand gets into the wrong places when refilling and will sand to come out into the pool or out of the backwash hose. But it should go away after a few runs. In general, you shouldn't be losing sand from your sand filter. Nor should any sand be coming out during backwashing, rinsing or filtering.
Replacement sand for your sand filter typically costs around $25 per 50-pound bag, and your filter may require 100 to 600 pounds or more depending on the size and model.
The appearance of brown algae on the bottom of the pool is a sign of the beginning of an infestation of mustard algae. This is one of the most difficult types of algae to get rid of, and gets its name from its yellowish-brown color.
A nylon or rubber brush is the correct choice for scrubbing the sides of a soft-sided above-ground pool. A large pool brush makes quick work of the job, but you may need a smaller brush to clean corners. Once the particles have been removed from the sides of the pool, turn your filter back on and agitate the water.
Run Your Pump (Longer)
Most pools need to run around 6 to 8 hours per day to complete a single sanitization cycle of the water. While this is adequate, running the pump for a longer period will filter out any dirt that's floating around before it has a chance to settle at the bottom of the pool.
Sand filters are least effective but also the least expensive to buy and use. Cartridge filters are more effective but are more expensive to buy and use. DE filters are the most effective but are the most expensive to buy and use.
The sand in your pool filter needs replacing every three to five years, sometimes even longer if your pool remains in relatively good condition when it's open. If you run your pool filter often all year and have a heavy bather load, the sand may need replacing sooner than three years.
You should backwash your DE pool filter about once a month during pool season. In addition to the regular schedule, you'll want to perform additional backwashing if: You've been running your pool filter for 48 hours straight. This can cause a pressure build-up, even if the filter grids look clean.
Can You Backwash Too Much? If you backwash your pool too much i.e. time duration and/or close frequency then yes you can cause a lot of problems. Some problems that can arise from backwashing your sand pool filter too much are: Loss of water – 500+ litres of water can be lost in each backwashing cycle.
The process of backwashing dislodges trapped debris and contaminants, flushing them out through your value's waste line or a hose that is connected to the pool pump. When the filter media is clean, the pressure gauge is lower and water can easily flow in and out of the system.
After the hose fills with water, backwash your sand filter for 2 - 3 minutes, or until water runs clear. Shut off the pump motor and push the T-handle back down into locked position. Turn your pump back on and note the lower pressure.
In unsewered regions, backwash water is to be discharged to a grassed, vegetated or garden area, or a stone-filled trench either open to the surface or underground (similar to a septic tank absorption field).
Do not operate your filter pump without having the D.E. powder coating the grids, or you will see the filter pressure rise very quickly, and if left in this manner the grids can collapse or the fabric can become clogged or damaged. As the pressure gauge on a D.E. filter increases, flow rate decreases.
