Had a new liner installed a while back and just recently discovered something in the shallow end under the liner floor that is sharp. In my mind's eye, it is a triangular pebble or concrete chip and it is oriented "point-up". It is perhaps 1/4-3/8" in size.
Sigh... I do not want it to puncture the liner and I want to get the object out. Right now, all I can think of is to duct tape a 10-foot length of sturdy 1/2" tube to my shop-vac, drain the pool down, snake that 1/2" tube towards the object and try to vacuum it out.
But before I do that, I thought it worth a shot to see if anyone else might have a better suggestion, technique, hint, tip, trick that might be better than *draining the pool down* to get at the object.
