Retaining wall question

[Watermom]

Babzog --- I merged the second thread you created about your retaining wall issues with this original one. It makes it easier to help if all the information about a particular problem is all kept within one thread.

Scratch my last post... called the pool company today and they said no backfill on the pool.

Not even on the bottom plates and rail - all must be exposed otherwise the warranty would be void. Well, if there were a warranty on it, it would be void. Since it's a used pool and has been moved, much of the original warranty is moot. Still, I want to construct this thing properly, so I'm thinking of sticking with the wall, though I'm still on the fence.

If I went with backfilling, am I okay to do so in a heavy frost area or is this one of the reasons why I shouldn't? The lady at the pool co. said that the backfill would prevent the pool from moving properly during a frost heave. Anyone here have experience with a backfilled pool in a frost area?

If I went with the wall, how then, would I construct the drain in the space (2') between the retaining wall and pool wall? If I dig down too close to the pool wall, would I compromise the soil's strength, leading to a potential collapse?

Anyone have pics of such a drain?
