Retro Drain

I am thinking of installing a retro bottom drain in my pond. I would connect to a sequence 3600 pump to a bead filter and UV clarifier. The drain would be about 6 feet from the side of the pond. Should I run the tubing through a bulkhead on the side of the pond? Do I need a sensor to shut off the pump if there is a leak in the tubing to prevent the pond from draining? Thanks - Chris

If you live in an area where you can run the pond year round, you can use a bulkhead near the bottom of the side of the pond.

If you live in a cold area, you will need to shut down the pond and drain out any pipes.  If you put the bulkhead fitting near the bottom of the pond, during the wintertime when everything is shut down, the water in the pipe will freeze.  Place the bulkhead in the top foot pond wall (then lower the water level below it when the pond is shut down) or snake a pipe over the edge of the pond.  You should have the retro drain and pipe setup that is in the pond on a union so that you can unscrew it in the fall and remove it in the fall so it won't freeze and bust up.

You can place a float switch in the pond or you can use a Levolor to shut off the pump if a leak occurs.  Keep it out of an area where the fish can bump it and accidentally shut off your pond.
