4″ Heavy Duty Bottom Drain – Easy Pro

Improve pond circulation and debris removal with the 4″ Heavy Duty Bottom Drain, available in standard (EBD4) and aerated (EBD4A) models for enhanced performance. Built with a rugged roto-molded design for superior strength, these drains feature a welded FPT threaded inlet that eliminates the need for rubber couplings, along with a threaded center stand pipe that securely attaches the dome lid to the base. A liner ring with sixteen stainless steel screws ensures a tight, watertight seal, while compatibility with 4″ Schedule 40 PVC fittings allows for flexible plumbing connections. The EBD4A model adds an integrated air diffuser in the dome lid, delivering air through the center stand pipe for improved oxygenation and circulation, with a 1/2″ tubing adapter and recommended airflow of 0.5–1.5 CFM. Ideal for maintaining cleaner ponds and healthier water conditions, these bottom drains provide reliable, long-term performance for professional pond installations.
