To remove the water more thoroughly, remove the drain plug from the bottom of the filter.

If you forget to, you may cause damage to your system or possibly destroy it which will turn out to be a costly mistake. Backwashing can result in a loss of water. While this is unavoidable, you can minimize the amount of water you lose by not overdoing the backwashing process.
Keep a close eye on the color of the water through the view glass and stop the minute it becomes clear. This will require you to top up the amount of sand in the filter. To minimize the amount of sand blowback into your swimming pool, run the filter system on the rinse setting for a minute when you do the top up. In the even your backwash valve is becoming too difficult to turn, it is recommended you do a teardown and lubricate the valve before any leaks occur.

The one downside of sand filter back washing is that, because water is expelled from the system and sent into waste, is that it…well…wastes water. While this is unavoidable, the key to not overdoing the backwash process and flushing out more water than strictly necessary is to keep a careful eye on the colour and quality of the water in the sight glass.
Sand filter systems operate most efficiently in the middle of the filtration cycle. This is partly due to the positioning, at any given time, of the sand in the filter, and, partly, because of the cyclical build-up of collected dirt and debris in the filter.
Finally, make sure you always turn off the pump before you either move or reset the filter valve setting. Reduce the Need to Backwash. Comprehensive Guide to Pool Covers. Make Backwashing Easier. Sold out. A swimming pool filter is the same way. A filter becomes dirty because of a high bather load, weather, foliage around the pool and other variables.
Your sand filter has a base layer of pea gravel and is filled approximately two thirds of the way up with a filtering media which could be silica sand, zeolite, or recycled glass. As water passes through the filter a layer of sediment builds up on the top of the sand bed.
As sediment builds up your filter, becomes more effective because the sediment is finer than the filter media itself and after a while it begins to filter even finer particles out. But that layer of sediment will begin to thicken and after a while will actually prohibit water flow through the filter.
That is when it is time to backwash. If the filter slows the flow of the water because it is dirty it also slows the turnover rate of your pool. Turnover rate is how many times the entire quantity of water cycles through your filter per day.
