Hi. My name's Mike and I'm from Long Island NY. I've had a new vinyl pool installed (cement sides) and the masons that installed the bluestone coping let a lot of mortar fall into the pool. In addition to trashing the grids on my new filter, it seems that the pool service company is so far unable to remove some sizable pieces of concrete that collected in the corners and seams. They are concerned that being aggressive will tear the liner.
This is my first pool so I'm just barely getting up to speed with everything. I'd love to know if anybody else has experienced this and would welcome any advice to solve the problem.
