What does it feel like when you jumping into the swimming pool? It might be immersed in cool and fresh water. But in reality, how fresh is the pool water? Certainly, you can use some disinfector the way you are supposed to and you clean up the pool. If it is been a few years that you didn't change the pool water, it might be time to do it and make the pool clean.

WHY

Now, the first thing you need to know is that why should you drain the pool regularly? Do you remember how long has the water in the pool was there? Months or Years? Even if you insist on keeping up with repair and water chemistry, there will ultimately come a time you must to change the water. 

As a matter of fact, the total dissolved solids which refers to the remnants of whole the chemicals you have put into the pool over the years, as well as mud soil, fallen leaves, and other unnameable contaminants. So much TDS in the pool water and it may grow to the point where they cannot be filtered out. Once that happens, the ability of the pool to maintain proper water chemistry will be disturbed.

It is exceedingly difficult to lower it when the level of TDS reaches a high point. Think about that is there a certain way to put more chemicals into the water to reduce the residue of total chemicals you have already put in the pool? That way just like trying to clean lots of marl by rubbing more marl on it. The best way is to drain the pool and refill it with clean water.

Therefore, we suggest you using a digital TDS meter to monitor the level so that you can know what time need to change the pool water.

WHEN

Generally, the in-ground pool should be entirely drained and the water changed every 5 to 7 years. Precisely, how long you need to change the water will depend mainly upon your maintenance schedule, how often the pool is used, what type of environment your pool is in. 

Not every season is suitable for drainage, the mild climate might be the best choice which will avoid unnecessary sunlight, high temperature and moisture damaging the mosaic pool tiles and the filtration systems. What's more, drainage is also not suggested in these weather conditions, for example, rainstorms and typhoons, which will increase extra pressure to the bottom of the pool.

HOW

We believe that it is better to know what step you need to do before you start doing something, which will help the process go more successfully and help you save more unnecessary costs.

1.Going to rent or by a submersible pump

You can buy a submersible pump in a home improvement store or the local hardware. With an inexpensive price, a good pump can make work more efficient. Don't forget renting rubber fire hoses otherwise the running water from the pump will drain everywhere.

2.Set up the pump well

Where is a suitable place to put the pump? We advise that you put a submersible pump on the floor in the center of the deep end. There are two points you need to pay attention to one is that making sure the electric wire is long enough to reach from the deepest part of the pool to the nearest outlet without being elongated as well as trying not to use an extension cord. The other is that making sure the rubber fire hoses are long enough to extend the pump to the place you will be used to dispose of the dirty water from the pool.

3.Paying more attention to monitoring the falling water level

During the draining process, you should keep your eyes on the rubber fire hose and the electric wire stays connected and make sure that the rubber hose remains working well to avoid the problem of flooding.

When every foot the water level drops, you can use another hose to spray the previous waterline of the pool, which will save you more time to clean the pool particularly if your pool is dirty.

4.Removing the submersible pump

If the water level reaches too low, the pump can no longer discharge any water from the pool so it will appear a small puddle. At this time, you can drain the last water manually with a bucket.

It is necessary to open a hydrostatic pressure relief valve so that it can give the underground water accumulated under the pool a flowable path to avoid your pool from popping. 

5.Cleaning the pool tiles

Choosing a good swimming pool tiles suppliers with premium products, which will help you reduce more cleaning work. There is an optional way for you: an acid wash will make your pool restoring luster and looking more transparent.

6.Refilling the pool

How many hoses did you need? It depends on the size of your pool, if your pool is normal size, it might need to put one or two garden hoses into the pool. After putting the hoses, you can turn on the taps, meanwhile, calculate the approximate time it needs and constantly keep watch on the level of increasing water.

7.Restart the pump

While the water arrives about the middle of the skimmer, you can turn off the taps, put away the hoses and restart the pump. Then what you need to do is waiting for the pool water to settle, maybe it needs to settle for a few hours.

8.Adding the chemicals and enjoy the refreshing water

After settling, you can do the test for the pool, for example, the alkalinity and acidity of the water or the calcium hardness. Finishing this test, you should adjust the acidic and basic capacity of water as well as the hardness according to the test report. The last step is adding some chemicals into the pool such as salt, cyanuric acid or chlorine.

In reality, knowing how to drain and refill a swimming pool is an essential part of pool care. Maybe you think it seems too troublesome, but if you have done it once or twice. Following the above step and take preventive measures, you can do it well on your own and save lots of money on hiring professional workers.
