Last season our pool had a slow leak. pool was drained during the winter. I did not think we would be using the pool again since we planned to move. well the move did not take places and now the kids are inquiring about the pool, uggh! I believe the leak is the result of normal wear (pool about 5 yrs old), bleach use (stains on bottom of pool), and pebbles (have a couple lumps underneath pool). Looking for advice, thoughts about inserting pool liner, maybe just to cover bottom, thinking that water pressure will seal liner to pool bottom to stop leak. If not that, then use the full liner. As for repairing, I'm afraid there may be several small holes and I may miss one. Getting ready to move pool, clean and redo ground beneath, its a little lopsided anyway. wha' cha think!
