Having an excessive amount of water added to your pool in a relatively short timeframe can lead to several problems, among them, malfunctioning of your pool equipment, the accumulation of algae and deck damage.
What Happens If Your Pool Water Levels Are Too High? When your pool water levels exceed the middle part of your pool's skimmer, your skimmer is not going to work properly. The water flows into the skimmer at a higher level, it causes the water to not get skimmed properly.
After an extreme overflow, you will need to remove water from both the outside and inside of the pool. You may also need to adjust your pool chemicals, since the extra water may dilute the water and reduce the effective chemistry.
The pool will only overflow by the amount of rain in excess of the amount of rain needed to fill the pool to the top. So if your pool is the normal 3” below the top, the rain would need to exceed 3” before any additional rain would be available to overflow onto the deck.
But large quantities of precipitation combined with an overflowing pool and poor drainage can cause problems such as flooding, structural damage to the surrounding buildings as well as out of balance swimming pool water chemistry.
If you get more than five inches of rain in an hour, or if your pool wasn't properly designed with sufficient overflows, then your pool may overflow, which can put you at risk of water getting inside of your home and causing serious damage.
The main issue that you will have if your swimming pool has too much water in it is the ability for the skimmer to keep the surface of your water clear from floating leaves, grass and bugs. This will only occur if the water levels have risen so much that the entire skimmer beneath water.
It is recommended you have your water level between one-third and one-half up the swimming pool skimmer box opening. If the level is higher than that, it may slow or even stop debris from being pulled into the skimmer box through the plate or valve.
To prevent potentially dangerous electrical issues, it's imperative that you turn off the power to your pool equipment — such as pumps, motors, filters, heaters, chlorinators, and lighting fixtures. Even if you turn off the power to your pool equipment, it can still be damaged by wind, rain, and debris.
The recommended level for swimming pool water is 80-120 ppm. When pool water is found to be low in alkalinity (below 80 ppm) it is recommended that this level be increased.
Your water should only be drained so it sits just below the skimmer and jets. This helps make sure that no water can get into the pumping system. You may also need to drain a few extra inches of water, depending on the type of pool cover you're using.
Close the pool for winter – but don't drain it.
In winter, the water in your pool is still your friend. Especially when properly winterized, it helps to protect the pool liner, keep it clean and prevent unnecessary damage from debris, harsh weather and other factors.
How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
If ground water is not a problem a pool can be left empty for weeks or even months as long the hydrostatic relief in the bottom of the pool is open and functioning. If the time frame of the pool being empty gets into freezing weather there is real risk of freeze-thaw damage to surface of the pool.
Sometimes also called an ice compensator, a pool air pillow is used to compensate for the accumulation of rain, snow, and ice that may build up on the pool cover over the winter months. By placing an air-filled pool pillow under the winter cover, you create a void in the water and on the top of the cover.
Freezing temperatures
September and October are a good time to close the pool because the weather is ideal. It's still warm to be outside, enjoying the sun, even if you hate to say goodbye to summer. But once those temperatures start dropping significantly, you're going to kick yourself for not closing the pool sooner.
First, if the draining is done at the wrong time or under the wrong conditions, you can actually risk damaging your pool structure and liner. All the water from your pool needs to go somewhere when it's drained, and that usually means the ground.
You may throw up your hands and decide the best course of action is to drain the pool and start over. In fact, draining a pool should be a last resort. Most in-ground pools will have to be drained and refilled at some point. But cleaning should not be the reason to do it.
The water in the pool helps hold the liner into place. If you drain your pool you can cause your vinyl pool liner to shrink and upon refilling, if the liner has lost its elasticity it can cause the liner to rip or tear. The liner can also become hard and brittle.
Excess chlorine can alter the pH level of the water in the pool, making it more acidic. The acid levels can cause any of the following symptoms: Irritant dermatitis which is a red skin rash characterized by raised itchy red bumps. Eye irritation and over-dilated blood vessels in the eyes.
At chlorine levels over 10 ppm, swimsuits can begin to fade. Pool covers become damaged, and the water is generally uncomfortable and unsafe for swimmers. Close the pool and keep covers off until chlorine levels fall back below 5.0 ppm.
Bobbing, where you sink underwater and slowly exhale a stream of bubbles through your nose and mouth, is a way to grow familiar with breath control. When you return to the surface, inhale and then sink back into the water and exhale again.
Heavy rains will dilute your pool alkalinity level, causing it to fall by 5-10 ppm a day. Low Alkalinity and low pH levels in pools can create a corrosive water environment. Corrosive pool water can result in the damage of underwater metal surfaces, such as pool lights, ladders and rails.
