Plumbed Draining Tray

Ideal planter for my balcony would have drainage which I could plumb so that the water is routed off the balcony.  Self watering containers could probably be customized for this.  So far I am focusing on creating a drip tray with plumbing routing the water off the balcony.

Common Parts

I use economy-priced of-the-shelf components.

Tray

Elbow 1/2" male thread to 1/2" barb

1/2" tubing

I took the design through a couple of iterations.

Standard Bulkhead Design

I started with a standard bulkhead.  Unfortunately it is too bulky, so I had to cut it short.  Also to reduce the height I used the included rubber gasket on the bottom instead of the top (water) side.  This made use of silicon during assembly mandatory.

Parts

1/2" Plug is used to hold bulkhead
while cutting it short

Use silicon while assembling.

To reduce the amount of standing water
I cut some groves.

DIY Bulkhead Design

I was somewhat disappointed with standard bulkhead.  If messing and modification is requried, I might as well use cheaper components.  I could not find 1/2" nuts to hold the elbow, so I decided to create these.

This part will be used to create two nuts.

Parts

Two nuts cut, the rest to be discarded.

Dry assembly

Assembled with silicone

That's it, folks!
