We bought a house back in October of 2011 which had an inground pool. Over the winter, vinyl liner started falling out and was not worth saving. After getting a quote to have someone come in and install a new liner, which was right around $4000, we decided to do some research and DIY the liner ourselves. Through some good days and bad days, we finally have a new liner installed and because of TFP our pool is sparkling clean. I would recommend the BBB method to everyone. It has worked very well for us.
