Nope. It is not an upside down pic-nic table!
Plumbing in the hydrostatic releif valve.
Every place the PVC plumbing will penetrate the shell we add a water stop ring. This keeps water from 'chasing' the plumbing.
After removing the corral we backfill up to the plumb run and...you guessed it plumb the pool.
Here you can see the main drain line and the return line.
We back fill and tamp with clean compactable sand.
