What should I do if the sand in the sand tank flows into the swimming pool?

What should I do if the sand in the sand tank flows into the swimming pool? The sand tank in the swimming pool is a device used to filter pool water. It is filled with quartz sand. The quality of filtered water mainly depends on the role of quartz sand. But it was fine at first, but suddenly quartz sand flowed into the swimming pool. What happened? What should I do? There will be problems. You can check whether the joint is tightened. If there is no problem, check the octopus. Generally, this phenomenon is most likely due to the problem of the octopus.

If the octopus cracks, sand will enter the water from the gap and flow into the pool together. This also causes sand to flow into the pool. Then how to deal with the sand flowing into the swimming pool? First of all, the broken octopus should be replaced so that the sand will no longer flow into the swimming pool, and the missing sand should be replenished.

Quartz sand has various specifications, and the most common sand diameters are 1-2mm, 2-4mm and 4-8mm. When filling, you can choose the same specification as before. If there is too much outflow, you can choose to reload, and fill an appropriate amount of sand according to the size of the sand tank (it is not necessary to fill it up, just fill it with more than 2/3).

Then clean up the sand in the swimming pool. The sand must be removed as soon as possible, so as not to affect the swimmers, and it is not good to put it on the feet. To clean up the sand, a swimming pool suction machine is generally used.

Both automatic and manual suction machines are acceptable. To choose a sewage suction machine, you must first understand the size of the swimming pool, and then determine whether to use a small, neutral or large sewage suction machine according to the size. That is to determine the power, and then choose whether to use automatic or manual according to your budget and preference.

These machines can not only suck sand, but also clean hair, fine dust, etc. But the most important thing is to change the octopus. To prevent sand from flowing into the pool again.

----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. Power failure or motor protection tripped
b. Pump doesn't vent
c. Pump doesn't fill the water
d. Suction line/hose leaking
e. Transparent cover not properly installed - check filter basket - even bolts
f . Inlet suction process is too large g.) Total resistance loss exceeds the allowable range of the pump - recalculate the required pressure
h. Mechanical shaft seal leakage
---Poolking has a professional Quality Control team to guarantee each product is 100% inspected before packing. For example when the filter inner tank comes out, they will make a first water testing before bobbin wounding. After installation all the connections or manhole & sightglass, they will make the second water testing. During the packing procedure, QC team will inspect all the details like wounding, neck, internal resin and so on to make sure no leaking and without flaw.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
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
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
9. Stop the pump
10. Turn the lever to RINSE , start the pump and rinse for about 15~30 seconds. Stop the pump and turn the lever to FILTER . This is the normal operating position .
11. Close the drain outlet valve and start the pump . Switch on the electric heater if any .
