Flowmaster 3 Commercial is a 3 removable top drain that features a double wall base and a snap in top (PVC). When installing this drain the tops are staggered past the joints making the joints very rigid. Because the Flowmaster 3 Commercial Deck Drain tops are removable this drain is easy to clean and the tops can be replaced if necessary. Flowmaster 3 Commercial Deck Drain is used on many commercial swimming pools, patios and other areas where large amounts of water need to be removed.

It is recommended that you drill and pin (3/8″ rebar) the base at 3 foot intervals to stabilize against any movement in the concrete slab. Stegmeier LLC offers a fiberglass Drain Dowel for this purpose.
