Adding a bottom drain is a great way to remove solids and prevent stratification, especially in ponds over 3' deep. EasyPro bottom drains are easy to install and come complete with everything needed to make a water tight penetration through the liner. The built in air diffuser model provides the ultimate in self cleaning action. When the air bubbles rise the dirty water is pulled into the bottom drain.

3" BDA and BD1 Features:
• Available with (BDA) or without (BD1) air diffuser in lid, using air increases circulation and cleaning capacity.
• Both have dual rubber gaskets and six stainless screws for water tight penetration through liner.
• For use with 3" schedule 40 PVC fittings and pipe.
• BDA has 1/2" barbed inlet fitting, recommended air flow through diffuser is .5 - 1.5 cfm.

BD1 AND BDA

The popular EBD bottom drain has been redesigned for 2011, and is now available with or without air diffuser. Welded FPT threaded inlet eliminates the need for a rubber coupling. Threaded center stand pipe securely attaches dome lid to base. Sixteen (16) stainless screws securely attach liner ring to base with water tight seal. Heavy duty, roto-molded design offers superior strength. For use with 4" schedule 40 PVC fittings and pipe, use 4" male adapter (MA40) to connect to 4" pipe, use reducing male adapter (RMA4030) to connect to 3" pipe.

EBD4A incorporates an air diffuser into the dome lid. Incoming air is delivered up through the center stand pipe allowing air tubing to be installed under liner. The EBD4A tubing adapter at the bottom is 1/2" with the recommended air flow through diffuser at .5 - 1.5 cfm

Many pond builders have found that adding a bottom drain/skimmer diverter helps keep a pond cleaner. Fish waste and other muck that accumulates on a pond bottom can be easily removed by a bottom drain. Ponds that are over 2' deep can become stagnant without a bottom drain. The bottom drain is installed under the liner.

NOTE: The control valve at the bottom of the skimmer allows you to adjust the amount of water coming from the bottom drain. This will also increase or decrease the water coming in from the top of the skimmer! A bulkhead fitting is installed in the skimmer. A PVC male adapter connects the flex PVC to the bulkhead fitting. A valve is placed inside the skimmer box to control flow. When the pump is turned on, water will flow into the skimmer through the skimmer faceplate (surface water) as well as the bottom drain. You can control how much water goes in thru the top/bottom inlets with the valve on the bottom drain.

Bottom drain kits include BDK bottom drain, bulkhead fitting, valve and fittings.
Does not include PVC pipe. 2" kit recommended for PS1 skimmers, 3" for PS2 skimmers.
