I have received the same mixed information about Waterworld going bankrupt. All I know is that when I dealt with them over 4 years ago, they were not reputable and in fact, underhanded. A friend of mine has had to sue them for improper installation and faulty product.
Last year or so, they were selling Viking products and I knew that would not last. Viking has a national reputation and sure enough, this year, Waterworld has a new website but no Viking products to be found. Just their own Waterworld products......TROUBLE
