You may have a large chunk blocking the discharge valve, try opening the valve with the pump off and moving a broom handle upinside the valve, you should have a two and one half inch valve for the dischargeso a handle or something smaller, just may be blocking the hole at the valve to let the water out.most people have a problem getting the filter to prime and keep running. If you have a popular punp and filter just remove the discharge valve and see if anything is blocking the hole.
no... you should call a professional to come inspect your pool
Technically, you don't backwash the pool, you backwash the filter. This is assuming you have a sand or DE filter. The filter valve should have a backwash setting. Turn off the pump, set the filter to backwash, and turn on the pump unitl the water runs reasonably clear.
Backwash first then shock. If you shock and then backwash you will be throwing away the shock you just put.
A Pool is filtered for a certain period or periods of time per day. When the backpressure in front of the filter becomes too high it is time to backwash the filter if you have a "sand" or "DE" filter. After back washing i.e. when the water is running clear through the observation bubble on the side of the multiport, stop the pump and set it to rinse for about a minute or when the water in the bubble runs clear again. The rinse stops cloudy water from being pushed back into the pool. Sometimes but not always, you may find that the backpressure increases into the red rapidly after vacuuming the pool floor, this means it needs a backwash and rinse.
how do i calculate the volumn of backwash in a pool
That can change from pool to pool, In most cases if the pressure indicator is up to about 3./4 of the way it is time to backwash. this coincides with weak suction.
Average pool filter: Backwash 5 minutes and rinse for 1 minute.
When the pressure on the filter pump is above 20 psi.
Setting the filter to backwash cleans the filter, running your pump to filter cleans the water in the pool. Brushing the walls of your pool cleans the walls of your pool... and so on.
When adding stabilizer to a pool you should not have a backwash valve open. Stabilizer should be added directly into the skimmer basket and you should open the skimmer all the way and close off the main drains for 24 hours.
Vacuum the pool slowly on backwash.
No you only backwash your pool when your filter pressure on your filter is high 30psi and above on most pools. If you backwash your pool be sure to add two scoops of de to your skimmer. If the presure is still high the u need to clean the filter
Depending on the size of the pool and the size of the filter and the amount of times you have to backwash, also if you have had a lot of rain then you may need to backwash more than usual. If you put the pool in and the filter and you know how old the sand is, if you are backwashing more than usual,change the sand. Also before you backwash check the pressure of the water going back into the pool, then backwash check the pressure again the pressure should for any size hayward pump push your hand away if it does not then change your sand.
OF COURSES YOU CAN'T
There wont be any dirt under the sand. When you vacuum your pool you should do it on filter mode Otherwise you will lose a lot of water for nothing, this would be especially wasteful in the case of a salt water pool. Ofter having vacuumed the pool on filter mode and if the pressure gets too high backwash. after backwash rinse for a minute, then return to filter.
If the pool is really dirty then it is best to set the filter to waste.
As soon as I notice a different smell in the pool, it helps to add a focculant to the skimmer and after 24 -36 hours backwash the filter. Shocking the pool at this time should control the odor.
You add D.E. to a pool when you do a fresh filter clean. You also add D.E. if you have to backwash your pool more than normal. When you backwash the pool it is also dumping the D.E. out so it needs to be replaced to keep the grids covered so the pool can filter properly. Hope it helped
You should not put chemicals in the pool while the vacuum is in. Put the chemicals in and give them a chance to work first. Then you can vacuum and backwash the filter as needed.
No absolutely not unless you want to waste a lot of water you backwash a pool when the pressure in front of the filter becomes too high or goes into the red.
Drain/Backwash the pool, clean the inside, and add fresh water.
Its recommended to backwash the de when the pressure goes over 7 psi from the last time u did a backwash
There is no point back-washing the pool if the filter is not dirty as this will only waste water and if you have a saltwater pool salt.
Backwashing a swimming pool cleans out the sand filter. It reverses the flow to push all the trappings from the filter out.
Potatos dont fly when creepers go into the pool. Hope this helps
