I use Hayward Pool products because I find them to be excellent quality while reasonably priced. They have a great range of products from pumps and filters through heaters, pool lighting, sanitation and automation products.
In fact, they have pretty much anything you might want if you own a pool. They do not sell retail so if you want to purchase product from them you need to go through a distributor / agent or repair company such as David Pierce Pool and Spa Repairs.
