Installing the Koi Village Aerated Bottom Drain

[Ronin-Koi]

I posted this in the trader forum to answer someone's question about the Koi Village Aerated Bottom Drain. Thought it might be of interest in the construction forum as well, so here it is. I decided to use some epoxy at the air connection like HarveytheKoi, and installed some vertical rebar like Clay.

I bought the last two drains that Gene had from his first batch of aerated bottom drains.

Photo 1. Parts that come from Gene. In the zip lock are screws for attaching the liner ring.

Photo 2. Fittings for the air line at the bottom of the bottom drain. The air line on the drain is threaded femal 3/4". I used a 3/4" elbow, short piece of 3/4" pipe, a 3/4"x1" reducer, and then to a 1" 45 degree elbow. This would fit into the 1" line to my filter chamber. I got some pipe joint compound for the threaded connection.

Photo 3. The bottom drain is made of ABS, so I used all-purpose cement to glue on my 4" dia. PVC 45 degree elbow. I chose to use two 45 degree elbows rather than straight to a 4" pipe because I will be installing a concrete floor for my pond and I wanted thicker concrete over the pipe, especially right at that connection.

Photo 4. Both bottom drains all glued up.

Photo 5. Bottom drain in the ground with rebar around it, in a hole waiting for concrete to be poured to set the bottom drain.

Photo 6. Bottom drain installed with about 8 inches of concrete underneath it for support with a rebar ring and vertical rebar to tie into the top layer of concrete to be poured separately. The 4" drain line sits on the right, and the 1" air line is on the left.

Hope that helps to explain at least one way to install the Koi Village Bottom Drain. Hope this also convinces lots of people to go out and buy them. Gene's a good guy, and I am happy with the product... or at least I think I will be once the pond is completed and the drains are operational.

- Wayne, will start a thread on construction of the rest of his pond in the next day or so, hopefully.
