Hi-Flo Weepers

Preferred Engineering introduces HI-FLO a engineered weeper designed to maximize flow rate when experiencing the low pressures found in window and sliding door sills.

The cover automatically opens to let water escape, then uses a positive-close action to block drafts and insects from entering the house. Compatible with most window and sliding door designs, HI-FLO reduces water build up and the risk of water damage. The system is specially engineered to give maximum flow rates and drainage performance, even when working on a 45º angle.

Unlike other drainage weepers on the market today which are made of nylon, HI-FLO is fabricated from polycarbonate, preventing swelling from water build-up and causing malfunction of the weeper door.
