Hi Everyone - new member here, posting my first thread. Are there any issues with changing out the drain covers (including the frames) on a vinyl liner pool after it's filled? I'm thinking not, since I seem to remember the pool guys cut those in after it had started to fill up, but I wanted a group opinion on it. I have the gear to be able to sit on the bottom and do it, just wondering if messing with the frames might cause leaks. I want to change them from their current beige color to dark gray, to blend with the liner. I already changed out all the jets and they look great - basically invisible Thanks for any and all input!
