When we replaced our liner this spring, we found a bunch of the "caps" on the top rail had been broken - the piece of plastic that the screw goes into broke off, so the screws now don't reach far enough. Can I order new caps? Or just use longer screws (some of them may not even have enough of the plastic left with thread though!)
Also, a couple of the top rail sections are cracked. When should I replace those (assuming I can get replacements)? Now, or wait until spring? Do I have to have the water drained halfway or all the way or can I do it when the pool is full (I'm guessing no on the last option)?
