Where do my drains go?

Deck, downspout, and pool overflow drains will terminate just beyond decking where there is proper fall for water to drain away from the deck. Emerald Custom Pools uses green pop ups that only open when water is flowing through the drain to prevent debris from clogging the drain. A valve is also added (in an irrigation box) which can be closed by the homeowner to prevent excessive loss of water in the pool.
