Backwash - How to?

[pringlee]

I did everything correctly and i dont know why but clean water was coming out of the hose. I lost like 1 or 2 inches of water in the pool. Yes the pressure came back to 10 but after 5 mins it went back to 20. My pool has 20k gallons. I decided to buy a TigerShark. Will it help?

It should go from teh pump to the filter to the waste line. It sounds like your is just going from the pump to the waste line. Usually you have to switch a valve (while the pump is off) to backwash to get the water to flow backwards through the filter and then out to waste. And yes you do dump a pretty good amount of water backwashing the filter.
