Swimming pools are a great way to cool off and have some family fun, especially during those hot summer days. But don't forget they can also be dangerous, especially if you have children.
It is not a good idea to leave the old pool liner in your above ground swimming pool when replacing the liner.
The return (called the return fitting or the return jet) is the plastic fitting where the filtered water goes back into an above ground swimming pool.
Above ground swimming pool filter systems fall into 3 categories or types. Sand filters, earth filters, and cartridge filters are the choices you have for above ground pools.
