I wouldn't have an above ground pool. And I am sure I wouldn't buy one from Walmart.

We work on Pool Pumps and motors. Above ground pumps come in from brand new in three years. 80% of them are pronounced dead at that time. In ground pumps come in after 7 years and get a new set of ball bearings and they are good for 7 more years. As for the pool itself, there is no comparison.
