quote; for the pex run to the pool fill, do i have to change to change to
pvc to run bedded in sand under the pavers around the pool, or
is pex legal in such a situation? i was going to use schedule 80 pvc,
but after looking at the pex, it seems pretty indestructible.
Nomrally, you do NOT need anything larger than 1/2" PEX to the pool filler, and NOWHERE in the discussion about the pool filler do you mention the REQUIRED antisiphon backflow prevention valve, which MUST BE located at least 12" above the pool's deck, unless the pool fill is an above the pool nozzle.
