Every Journey Starts With a Single Step...
Step 4 -Hook Up and Level BIOFALLS®

• Before you start to level the BIOFALLS®, it is wise to install the bulkhead fitting and PVC pipefitting.
• Install the bulkhead fitting so that the rubber gasket is on the inside of the container and the plastic gas­ket is on the outside, with the threaded flange sticking out back of the BIOFALLS®. (Note: BIOFALLS® Grande does not contain a plastic gasket). 
• The bulkhead fitting should be installed and tightened until the rubber gasket on the inside of the BIOFALLS® begins to bulge outward. (Note: Bulkheads are reverse threaded).
Tighten the adapter one to two complete turns past hand tight. Do not over tighten bulkheads may crack.  Use Teflon thread or add a small bead of silicone to the threads of the PVC pipe fitting to ensure a watertight seal. Then screw the pipe fitting into the bulkhead.

Setting and Leveling BIOFALLS®:

• In order to avoid creating a "volcanic look", do not set the BIOFALLS® too high. It normally sits into the ground a few inches so that you create the perception that Mother Nature herself has installed the waterfalls.
• To avoid uneven settling, compact the area beneath the BIOFALLS® with a hand tamper.
• With a two-foot level check the level of the BIOFALLS®. Your BIOFALLS® should be level from side to side and tilt forward approximately 1/4 of a bubble on the level.

Attaching Flexible PVC Pipe:

• The filter is now ready for the flexible PVC to be glued into place using PVC cement specified for use with flexible piping.
• Prime the inside of the PVC fitting and also the outside of the pipe where the flexible PVC cement will be applied.
• After printing, apply the cement to the fitting and the PVC pipe and fit the two pieces together.
• Hold the pipe into the fitting for 60 seconds to allow the glue to slightly set.
• Wait 10-15 minutes to let the glue completely set before you begin to bury the BIOFALLS®.
• Before you start to back fill around the BIOFALLS®, install the PVC support tubes. Otherwise you may not be able to get them in place.
• We also recommend having someone stand inside the BIOFALLS® to keep it in place and level while it's being back filled.
• The excavated soil from the pond can be backfilled around the sides and back of the BIOFALLS® creating a berm. Hand-tamper the soil while backfilling in order to reduce settling. Any additional soil can be spread around the far side of the pond in order to create a planting bed for perennials and annuals.
