Yes. if you don't you may end up with a cloud of dust being washed back into the pool.
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.
From the pool
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.
keep scooping, backwashing, scooping, backwashing. It has taken us all week to get rid of arm and hammer laundry deterent from our pool. Thought it was baking soda.
Yes, the filter won't work without the earth. That's what traps everything else.
Around 10 PSI if you have a 2 horsepower pump. It will vary, depending on the restrictions in the exit line. Pool Masters
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.
Cleaning a saltwater pool is no different to a chlorine pool. Checking for pH, chlorine levels, etc. is exactly the same, except you have to also check the salt level in the pool as well. Backwashing filters is also no different. The added component is the chlorinator, which is cleaned by placing it in hydrochloric acid in a bucket. Read up your manual if not sure. Experience: Worked in pool shops.
There is no "Rinse" associated with a pool pump. However it is associated with a "Multiport", a circular valve operated like a rotating lever on a Swimming Pool Filter.A Multiport has 6 positions.Filter The water passes through the filter media ( Sand or DE Plates), which remove dirt, and the water contiues on to the poolBackwash * The water passes from the pump, reverse route through the filter media and flushes the dirt ( and DE where applicable ) out the waste ( backwash) lineRinse * The water passes through the Filter as in "Filter", but goes out the waste line. This is the position to use after "Backwashing" the Filter. The purpose of Rinse is to (Sand Filters:- Pack down the sand and evacuate any of the 1/2 backwashed dirt out the waste, and not into the pool); (DE Filters, same effect, and also any DE that is in the multiport from BAckwashing, gets flushed out the waste line.Waste * Water leaves pool goes straight out the waste line, bypassing filterRe-Circulate Water goes straight back to the pool, bypassing the Filter. It is actually possible to remove the Filter from the multiport while in "Re-Circulate", as the Filter is basically not in useClosed Water cannot pass through the MultiportAll positions marked * remove water from the pool. Ensure that sufficient water remains in the pool that the skimmer(s) can still operate.ALWAYS TURN CIRCULATION PUMP OFF BEFORE OPERATING MULTIPORT. FAILURE TO DO SO CAN UNSEAT THE MULTIPORT GASKET WHICH CAN CAUSE LEAKS AND OTHER UNINTENDED NEGATIVE CONSEQUENCES.Greg M Simmons C.P.O.gregs.cpo@gmail.comTo specifically answer your question :Rinse could be called Flush !
shock pool its the only way to kill everything in water
48 square feet will give you more than enough and reduce backwashing frequency.
a rubber or silver bracelet should be safe in a pool just rinse them off after.
