How to Connect a Pond Pump to a Filter

A pond can make a perfect garden sanctuary to chase away the troubles at the end of the day. For the best-looking ponds, you need to employ a pump and filter to clear out impurities in the water. There are two main kinds of filter and pond connections: an integrated pump and an external pump connection. Connecting a pond pump to a filter in either one of these situations isn't a difficult water gardening task.

Integrated Pump and Bio Filter

Remove the plastic cover of the filter case, along with the charcoal filters, to reveal the interior of the filter.

Insert the biological material in the biological chamber of the filter.

Insert the pump in the pump container of the chamber. Feed the pump cord out through the cord opening.

Thread the pump tubing through the holes in the charcoal and mesh filtering mediums. Slide the filters down the pump tubing until they are in place on top of the filter chambers.

Thread the pump tubing through the top of the filter case. Snap the top into place on the filter case. Secure with any clamps, if present.

Slowly lower the filter and pump case into the pond. Allow it to gradually fill up with water, and continue lowering until it rests on the floor of the pond.

Plug in the pump.

Pump Attached to Separate Filter

Select and cut the tubing that you will be using to connect the pond pump to the filter. The input on the pump, output on the filter and the hose diameter all need to match in order to make a secure connection. Cut the ends of the hose at a 90-degree angle to provide a secure connection.

Tighten a hose clamp to each end of the tubing you will be using to connect the pump to the filter with the screwdriver. Tighten the clamps just enough to hold them in place.

Connect one end of the tubing to the input on the pump. Slide the tubing over the end of the nipple. Apply a few drops of biodegradable dish soap to the inside of the tubing if needed to help it connect. Once in place, tighten the hose clamp.

Connect one end of the tubing to the outlet on the filter. Slide the tubing over the end of the nipple. Use the biodegradable dish soap as a lubricant if needed. Tighten the hose clamp once the tubing is securely in place.

Lower the pump and filter assembly into the pond. If connecting an out of pond pump to an exterior filter, this step is not necessary.
