I am thinking about buying or building an above ground pool. The ones I have looked at have a skimmer mounted on the side and a return line mounted on the side. No bottom drain, so they must be vacuumed.
Would it be possible to build a system, using PVC pipe, that just hung over the side of the pool (or sat on a deck next to the pool)? There would be no holes cut in the liner. One pipe would come over the edge and have an elbow parallel with the water level. This would be the skimmer. Another pipe would run down to the bottom of the pool (similar to a bottom drain). These pipes would run to a pump and filter, and return line would be another PVC pipe going over the side of the pool and down a couple feet into the water.
The pump would have to be self-priming (maybe a special kind). The PVC could be painted blue to match the liner. The whole system could be easily removed in the winter.
Why doesn't anyone do this type of system? I think it would be a big advantage to not have any holes in the liner. I'm new to pools, please enlighten me.
