HOW TO BUILD A SMALL TOP DRIP SYSTEM
USING BATO BUCKETS
Part 2- Cutting
the PVC Stand

First cut and assemble the PVC stand. Please follow instructions carefully
in the order suggested.
1.
Cut pieces of the 1-½ schedule 40 PVC pipe to
the following lengths. Lightly file or sand the cut edges to remove burrs:
-
1 pc 31 long
-
1 pc 35-Ό long
-
1 pc 18 long
-
1 pc 17-½ long
-
1 pc 16-½ long
-
1 pc 16 long
-
2 pcs. 5 long
-
1 pc. 6 long
-
1 pc 2 long
2. Next, a word about PVC cement. You will apply a nice coat of glue to each PVC piece before pushing them together. Once you attach them together, you have all of 5 seconds to get it seated properly before a permanent and unbreakable bond is set. If you screw it up, throw in the trash and start over. (Hence the advice to buy a couple extra elbows and t-piece).
You are going to assemble and glue up the back drain pipe first. This is by far the trickiest part of the whole operation. Listen carefully to avoid a trip back to Home Depot.
To form the back drain rail, you will
need the 31 pipe, the 2 pipe, and the T piece. This pipe is what will
collect the drainage from your pots, and so it needs to be sealed off on both
ends so the fluids won't run down into the legs of your stand. (This will also
make more sense to you once you start putting things together). First study the
drawing below. See how you need to block off the inside of the tube at the elbow
and t piece (at the RED STOPS) so there is only one small restricted chamber
for fluid drainage?
So you will need to insert a waterproof block at the elbow on the left and the
outside port of the T piece. You can use whatever inert (plastic) material you
can find and seal it off with aquarium grade silicone sealant. (Do not
use household silicone, it has chemicals you don't want to feed your plants). We
blocked ours off with 2 wide styrofoam circles cut from building insulation.
You could cut 2 circles from an old Styrofoam ice chest, or whatever works! See
photos below.
3. Next, push one styro block into one elbow piece and do the same for
one end of the T piece. Push in far enough so you leave enough room for the
straight pipe to fit in there later. Apply a thick coat of silicone sealant on
top of the block, and around the sides of it. Allow it to set up, then apply a
second coat. The idea is, you want it totally blocked off so no moisture can get
through. Tip: do not use PVC cement for this. It melts the styrofoam. Trust
me.
4. Okay, time to glue up the back rail. For this, use the 31 & 2 pieces of straight pipe, and the T piece with the block glued in one side. Do not put the elbows on at this time. Make sure you put the T-piece on with the block side towards the outside, the 2 piece. This is how it should be assembled:
