Rainwater Terrace 3-TIER V2 User manual

INSTRUCTIONS –3-TIER (V2)
Please read these before you start
IMPORTANT NOTE: NEVER BUILD A RAINWATER TERRACE®
MORE THAN 3 CONTAINERS HIGH
The only tools you will need are for fixing the wall bracket to your wall and fitting
the Diverter kit and drain outlet tube. See instructions later.

How your Rainwater Terrace® works
When it rains the Rainwater Diverter (1)
collects water from the downpipe and starts to
fill the Top Planter Tray (2) where it can be used
by the plants attached to it and when full
overflows into the top container (3). The level
of water is visible in the Drain-tube (4) and
when it is full the water will overflow down the
central tube (5) and onto the next Planter Tray
(6) that supports the side Planters (7).
When that Planter Tray is full it overflows into
the next container (8) and when that is full
water overflows into the next Planter Tray (9).
Eventually the bottom container (10) is filled
and any excess is collected by the plinth (11)
and returned back to the drain through the
Outlet Tube(12).
Every time it rains sufficiently water flows
through the whole system so minimising
stagnant water.
Water can be drained from each container
independently through its own Drain-tube.
These each have a built-in tap that allows very
rapid filling of watering cans or buckets.
The top and side planters are provided with
special Capillary mats that draw up water from
the planter trays and feed your plants from the
bottom.

Location and Preparation of Site
Your Rainwater Terrace® should be positioned
close to a downpipe from your roof gutter so that
excess water can be fed back into the drain easily.
It can be positioned either side of the downpipe.
Your Rainwater Diverter should be fitted last so
that the correct height of installation is achieved.
When full your Rainwater Terrace® is very
heavy so it is very important that it stands
on a firm, flat, level surface that can
withstand at least 220 kg Check your
intended site with a spirit level in both
directions. Most paving has a slight slope
to encourage surface water to run away
from your house.
The plinth should contact the ground all round its
base so cobbles and uneven paving are not
suitable. Never install directly onto soil or any
surface that will sink under pressure.
If in doubt we recommend installing a concrete
base or a 60x60cm paving slab so that it can be set
level. Any cement used to fix and level it should be
allowed to set completely before installing your
Rainwater Terrace®.
Your Rainwater Terrace® is very stable but we do
recommend that you use the steel Wall bracket
provided for added security. Mark a vertical line on
your wall at the centre point of your base and mark
out the 2 screw positions as shown. Drill the 6mm
holes for the wall plugs and screw the bracket
securely in place.
If 2 or more Terraces are to be connected together
they must all be on the same level. If your site does
not permit this they must each be connected to
the downpipe independently.

Assembly
3. Place the first container on
the Plinth (it will only fit one
way) and assemble a bung on
the same side as the Outlet
Tube as shown. Turning the
Retainer ring in a clockwise
direction will pull the sealing
ring into place. Make sure you
stop the bung rotating from the
outside.
1. Lay the Plinth on its back as
shown, assemble the Outlet Tube
(12) to the spigot on the underside
of the Plinth as far as it will go and
feed the other end through the hole
nearest to your Drainpipe. (You can
soften the end of the pipe in warm
water to make it easier to fit)
2. Position the Plinth on the flat base
about 2cm from the wall. The outlet
tube can be cut to length later when
you are ready to connect to the
Drain.
4. Take one of the Drain-tubes and,
making sure the tap is closed, hook it
onto its holster. Insert the other end
into the hole on the container and fix it
in place using a Retainer Ring as
described above.

5. Assemble the first planter tray (one without the inlet
panel) –it will only fit one way round,. Place the second
container on top and fit the second bung and Drain-tube
as before.
6. Assemble the second Planter Tray and position the last
container on top to check which side you want the Drain-
tube to fit. It will be easier to take it off again to fit the Drain-
tube and the last bung then lift into place.
Make sure the wall bracket fits through the slot at the back.
If necessary reposition the plinth so that all the modules fit
together properly at the same time.
7. At this point you can check that the Bungs and tubes are
properly sealed by removing the top 2 modules and pouring
a bucket of water into the bottom container. Repeat for the
other 2 containers and finally fit the top planter tray.

Connection To A Rainwater Diverter
For your Rainwater Terrace® to work the outlet from your rainwater diverter must be
higher than the top rim of your top container otherwise water cannot overflow down
the central tube (5) that feeds the lower containers.
THIS WILL
NOT WORK
We suggest a
minimum of 10cm
There are many different Diverter kits you can use, which will depend on your
particular drainage requirements.
1. The Diverter we supply is suitable for standard 65mm square or 68mm round plastic down-
pipes and will divert a large proportion of the rain falling through your Downpipe into your
Rainwater Terrace® including any debris from your gutter. This will collect mainly in the top
Planter Tray which is easy to clean out.
2. If you have problems with bunged up soak-aways there are Diverters such as the “Gutter
Mate” that collect the debris in a filter that must be emptied regularly. This is also useful if you
have larger Down-pipes.
Follow the installation instructions that come with the Diverter kit with regard to
cutting into your Downpipe but always bear in mind the instructions above.
Avoid looping the pipe
5
Use the smaller diameter pipe
to connect it to the rainwater
inlet panel that is fitted to the
top planter tray.
See the separate instructions for
fitting your Diverter to the Down-pipe
Tip- You can
soften the ends
of the inlet pipe
in warm water to
make it easier to
fit.

To fit directly into your down-pipe
Drill a hole 35mm diameter with
a hole saw (not supplied).
Position as low as possible on
your down-pipe.
Then fit the rubber
grommet supplied.
Finally insert the free end of
your overflow tube. You can
chop this to length so that
about 3cm of pipe is inside the
down-pipe.
There are 3 basic types of
rainwater drain-away
1. Into a grate linked to a
drain or soak-away. Either
fit the rubber grommet supplied
as shown below or fit a plastic drain
cover and fit the outlet tube into that
2. Directly into a drain or soak-away. You
must use the rubber grommet supplied as
shown below.
3. Directly onto your land. Use the large cable tie
supplied to attach the outlet tube to the bottom of your
downpipe

Connecting The Outlet Pipe To The Drain

The Planters
The Side Planters use the large mats. Fold back
the flaps either side of the central tongue and
feed it through the slot in the bottom of your
planter then flatten out the mat as shown.
Add some compost to hold it in place and then
plant your plants, filling in with compost as you
go.
Fit your creation into the mounting slots in the
planter trays on your Rainwater Terrace® making
sure the tongue dips into the water.
If the planter tray is still dry you can top it up
through any of the vacant mounting slots.
The planter trays are replenished only when it
rains so check the level of water regularly.
The Top Planter uses the 4 small
mats that are fed through the
slots from the top.
TONGUE
Now for the creative bit! Your Rainwater Terrace® is supplied with side planters and a top
planter and pre-cut capillary mats for each that draw up water from the planter trays.
Press down firmly both sides so that
the back edge clips under this lip
TONGUE
You can use your planters
in the greenhouse and pop
them on when you are
ready.

To join 2 towers together you will need the
connector kit that comprises 3 connector tubes
and 1 blanking cap.
Fit the connector tubes using the Retainer rings
from the Rainwater Terrace® kits.
You only need one drain-tube for each level.
Fit the blanking cap onto the
central cone on the bottom
container furthest from the
drain as shown
Both towers must be at the same level to
operate properly otherwise all the planter
trays may not be replenished when it rains.
