I did a search and I still can't find what I need. I'm also not sure if this is the correct area.
When I vacuum my pool it doesn't seem to be getting rid of the debris or dirt. Here's what I do when vacuuming and the equipment I have:
I use a pole with a vacuum head attached to it and obviously a hose. I have an inground pool with a Hayward sand filter.
First off I put the vacuum head in the water with the hose attached. I then fill the hose up with water using the jet. When all the air is out I quickly put the end of the hose into the hole below the skimmer basket. So everything seems to be going good and I start to vacuum the bottom of the pool and I notice dirt or debris shooting back into the pool from the water jets. I do leave the the dial on the filter in the "filter" setting right? I have backwashed and it still doesn't seem to help. I also just put new sand in about a month ago. Any help would be appreciated.
