Generally, pool water needs to be replaced once every five to seven years. This should be done during mild weather so that your pool surface is not at risk from strong sunlight and heat. Your pool maintenance company can recommend when it is time to drain your pool.
Well maintained pool water can last up to 5, maybe even seven years before you need to replace it. This means weekly cleaning, functional filters, and checking ph levels every day.
When should I drain my pool? Pool industry experts recommend you drain your pool and refill it every five to seven years. No two pools are alike, so there is no set number at which you must drain your pool.
The pool must be maintained and taken care of regularly; if not, it may lead to various accidents, diseases, and infections. Maintaining the cleanliness of your pool is just one of the many ways of swimming pool care. It is recommended to have your pool cleaned at least once a week to keep it clean and uncontaminated.
8. You may be paying for weekly service but the guy is coming every other week, or even every three weeks. Since pool guys usually come when you're at work, you have very little way of verifying if and when they're there.
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.
No, you don't need to drain all of the water. We know that draining your pool is a hassle and you want to conserve as much water as possible; however, it is necessary to drain some of the water out of your pool. You will need to drain the water level down below the skimmer level.
Draining a pool is risky business for several reasons. Your pool is not meant to be empty. Whether you have a vinyl, concrete, or fiberglass pool, it is at its best when it's full of water. Once the water is drained, you open yourself up to all sorts of damage, so drain a pool only when there is no other option.
Once water is removed (and subsequently, the interior hydrostatic pressure), if there's an influx of groundwater, it will push the pool up and out of place. As a general rule, you shouldn't keep any pool empty for longer than it needs to be. Get the work done that you needed to do and refill it as soon as possible.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
Dirty water becomes a breeding ground for parasites, mold, and bacterial. The bacteria keep growing if the water is not wiped. Within 48 hours, you will see that the entire surface of the pool is covered with mold. As mentioned above, stagnant water attracts rodents and insects.
The Bottom Line about Pools and Chlorine
As mentioned above, you could probably swim in a pool without chlorine without any major health issues. However, long-term use of a pool lacking chlorinated H2O could make you sick or, at the very least, contribute to rashes and other types of skin irritation.
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.
The average cost to fill in an inground pool is $4,000 to $16,000 for full demolition or $2,000 to $10,000 to fill in with dirt. An above ground pool removal costs $300 to $800, or $2,500 with a deck. The cost to get rid of a swimming pool depends on the size, depth, material, and accessibility.
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. The older the vinyl material is the more likely this is to happen.
Most inground fiberglass and concrete pools are built structurally to withstand the weight of the dirt against them when drained. However, if the groundwater is high enough, it can push the entire pool out of the ground. The pool shell acts like a ship and floats up in the groundwater.
The first choice for draining swimming pool water should be to drain pool water into the sanitary sewer. In-ground pools typically have a sanitary sewer drainage inlet near the pool equipment. Pools and spas not plumbed with a sanitary sewer drainage inlet can be drained to a sanitary sewer line plumbed to the home.
Drain the water down to no more than 6 inches from the bottom of the skimmer if you plan to use a standard floating winter cover. Use your pool filter, switched to the "Drain" setting, to empty the pool water.
In warmer climates, Intex advises to keep your pool up, if you prefer. However, you must winterize the pool when keeping it full throughout the winter. If your area maintains tropical climates all year long, you may not need to winterize your pool at all, especially if you use your pool on a regular basis.
You may naturally assume it's best to completely drain your pool of water for the winter months, because you fear the water will freeze and cause damage. Actually, it's not good to leave your pool empty when the weather gets cold.
Aim to maintain a chlorine level of 3 to 5mg/l at all times. How frequently you add more chlorine will depend on your usage and bathing habits. It could be daily, every two to three days or weekly. For 1mg/l, add 2g per 1000 litres.
Shocking your pool isn't necessary, although, it's not a bad idea either. If you get an extremely heavy rain fall, you could shock your pool for good measure. This will help fight off any contaminants that the rain may have brought to your pool.
The main difference between Shock and Chlorine is that the shock is a high dose of chlorine, whose only function is to shock by raising the chlorine level in the swimming pool. On the other hand, Chlorine is a general sanitiser used to maintain a crystal and clear pool for swimming.
