Yes, the filter won't work without the earth. That's what traps everything else.
Most likely it is caused by an air leak somewhere in the system allowing the filter to drain back to the pool through the suction lines. You will probably see DE in the pump pot as well.
A satellite, probe, or spacecraft can gather information and send it back to earth.

Condensed water vapor from the sky typically falls back to Earth as rain.
Because dirt and small sand will pass through the filter the first time it is run after backwashing. By rinsing you are sending that debris, which could cloud your pool, out of the backwash port instead of back into the pool.
The connection on top is from the filter inlet (discharge of the pump). The connection on the opposite side of this one is the filter outlet back to the pool. The connection below the filter inlet is for backwashing the filter.
Your gauge could very well be bad, many pools that we took care of the gauge on the filter was bad, after backwashing the filter just check any of you lines going back to the pool and your should notice the pressure is a lot higher. A lot of people just check the flow by placing there hand at an outlet to check pressure than by walking over too the filter and reading the pressure, instead of buying a new pressure gauge.
I have a backwash setting on my sand filter. You can also add a sand cleaner in the bottom skimmer of the pump. After backwashing, it is recommended that you also rinse the head.
If you are backwashing more than you care to,or your filter pressue is high, or you put your hand against the outlet where the clean water is returning back to the pool and your hand does not get pushed away any of these reasons would be a reason to change the sand, depending on the size of the filter some filters need to be changed once a season every other season or not for years, bottom line you should only be backwashing after vacumning the pool. if your water in your pool is clean or clear I would say the sand is ok.
the amount of impurity's or dirt in the water. the amount of dust that gets blown into a pool how many plants and trees are around it. algae present in the water etc all of these will play a part in blocking up the filter surface and reduce through flow until it the back pressure becomes too high indicating the need for a back wash.
Cartridge and DE filters are the most prone to what is commonly referred to as "short cycling". This is when you clean the filter and the pressure goes back up right away. Over time, debris gets entrapped in the fabric cartridge element or DE grid material and it can not be removed by backwashing or cleaning. You can try a filter cleanser but it would be best if you replaced them.
Yes. if you don't you may end up with a cloud of dust being washed back into the pool.
What you do is put it on backwash for 2minutes then rinse for 1 minute, then you take out the chlorinator if it has one and take a pen or stick(not metal) and clean out all the white stuff and then spray it with a hosepipe and put it back in place, hope i helped!
All swimming pools with a pump and filter should have a back wash system. You must back wash your swimming pool filter when indicated by the pressure gauge on your filter. ANSWER 2:: Cartridge filters have no means to back wash. These filters must be broken down and cleaned manually. K
Backwashing is when you drink from either a cup or a bottle, then after holding the liquid in your mouth, release it back into the cup or bottle transferring spittle and food from between your teeth in the bottle or cup.
