Hi , I am new to the forum. I have a 24 Ft round Intex metal frame pool. We've had it about 3 years and this year decided to buy a sand filter so that we would not have to mess with the expense and trouble of the cartridges from previous summers. The pump is working great and I am pleased so far however ..... I am at a loss. How in the world do you vacuum with one of these ? We took off the over the wall skimmer that was used with the previous pump which was what was used for vacuuming. Where do you connect the vacuum ? Should we have left the wall skimmer attached and kept using it ? I am still fairly new to this. I am completely clueless. There were no type of instructions that came with the pump that explained how to address this . Please help
