Pool maintenance after rain

It is generally rainy in central China, so the weather will have a great impact on the water quality of the swimming pool. The main reason is that the air is polluted, and the rainwater is acidic. When a large amount of rainwater flows into the swimming pool, the pH value of the entire swimming pool will drop and become acidic; Rain will cause part of the water to flow into the swimming pool from the outside, bringing in various algae and bacteria; at the same time, the most rainwater will dilute the disinfectant so that it has no disinfection effect. The water temperature in summer is very suitable for the growth of various bacteria and algae. It becomes muddy, green, serious and even smelly. After the rain, we must deal with the water quality in time to prevent the water quality from deteriorating. Generally, the following steps are followed: 1. Put in the disinfectant first, and add 1.5 to 2 times the usual amount; 2. After two to three hours, Add PH regulator until the PH value reaches 7.5; 3. Add algaecide; 4. It is best to use filtration during the treatment process; agent). Poolking is the best swimming pool equipment manufacturer and supplier in China. Poolking exists to provide the highest quality swimming pool equipment while offering competitive pricing..

1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
a.Firstly you can tell me the pool size such as wide, length and depth.The circulation period is 4 hours,then we can use the pool volume divide by 4 to know the flow rate.Based on this we can know choose the suitable model for sand filter and pump.
b.Usually 4 meters can install a pool light.Both ends of the pool can install the ladders.
The basic filtration equipment can be chosen like above method.The other accessories can be fixed according to the using environment and requirement.
Using non metallic components fiberglass pressure tanks are rapidly replacing steel tanks in numerous applications. Fiberglass vessels offer several advantages in comparison with steel vessels .
