We do recommend vinyl liner pools as one of the best types of pools for the climate in Michigan. Of course, a floating liner is no fun. The good news is that Ask the Pool Guy Al Curtis has been in the business a really long time. He’s got a solution that he implemented on three pools this past weekend (the last weekend in May) here in Michigan. With all the rain water, liners were floating. One was natural causes (groundwater issues) one was because the owners used a small pump to take the water off the cover (word of advice – DON’T! – unless you are simultaneously filling the pool under the cover) though the challenge with that is that the small pumps actually draw water through tiny holes in the cover, resulting in you draining water from the pool. The third was a groundwater issue, along with a hole in the liner that was just below the skimmer – also patched today when the issue was remedied.
