So, I’ve bought a house with a pool. Things I know…. It is inground, has a liner that needs replaced, and it is oval. It is also a biology experiment! I am going to try to pump out the water because at present I don’t even know how deep it is. Where is the most economical place to order a liner with quick turnaround? Once I replace the liner, what’s next? Idk anything about my mechanics or if it’s functioning. I will cross that bridge when I come to it. I need to know EVERYTHING! Thanks!
