28” MAX

There are 2 options for installing the front fittings.

  

Option A

 has a single 

spigot at the bottom of the barrel and is recommended if you will only be 
using a garden hose to access the water in the barrel.  This configuration 
gives access to most of the water in the barrel.  A raised base is 
recommended to increase water pressure.  

Option B

 has a mid-height 

spigot and a bottom drain and is recommended for use with a watering 
can.

Option A: Bottom spigot only

1.  Find the front of the barrel; measure up 3” (76mm) from the bottom 

of the barrel and mark the center for the spigot hole.  Drill a hole using 
the (SMALL) 1-1/4” hole saw included in the set.

2.  Insert the threaded rubber seal into the hole. 

Pinch the seal into a “U” 

shape for easier insertion.

3.  Thread the spigot into the seal until the hex collar on the spigot sits 

firmly against the seal and the water outlet points down

.  

Soapy water 

or hand lotion on the internal threads will reduce friction and improve fit.

Rain barrels have been used for hundreds of years to harvest and 

store rainwater for use with plants, gardens, and other outdoor 

chores.
EarthMinded’s DIY Rain Barrel Kit can be used to make a state-

of-the art sealed rainwater collection system when used with 

a barrel or container you supply.  Our patent pending FlexiFit™ 

diverter installs easily by drilling a single hole into any standard 

2” x 3” or 3” x 4” rectangular downspout*. The diverter sends 

rainwater into the barrel. Once the barrel is full, the diverter will 

automatically pass excess water through the downspout. 

General description

Selecting a container

3

EarthMinded supplies only the parts and fittings to be added to a 
barrel you supply. Therefore, we take no responsibility for losses, 
damages, or injury caused by failure of the barrel, or improper 
installation of the parts.  Follow these instructions carefully for 
successful results.

This kit will work on both sealed barrels and open top barrels with lids.  
Open top barrels are easier to clean, and provide quick access to the 
water using a bucket or watering can, but present a safety concern for 
children; the lid must always be latched and locked.

Water weighs 8.3 lbs. per gallon. Be sure to select a sturdy container that 
can support the weight when full. 55 gallons of water weighs 465 lbs.  

Select a sturdy water tight container:

a.  A heavy duty or commercial grade plastic waste barrel with 

latching lid.

b.  A traditional wood barrel can make an attractive and natural 

looking rain barrel. Make sure it is in good condition, clean and 
water tight.

c.  If using a recycled barrel, use only FDA approved food grade 

barrels.  Make sure the barrel is clean and has not been used to 
contain toxic or hazardous substances. 

The container selected should be sealed, or have a latching lid to help 
prevent mosquitoes, animals, and children from entering the barrel.

This kit is not recommended for use with metal drums or barrels.

Before assembling the parts to the barrel we recommend that you select 
and prepare the location where the barrel will be used.  This will help you 
locate the fittings on the barrel in the most convenient location.

• 

Choose a downspout that is near the plants or garden beds to be 
watered.

• 

The downspout must be a rectangular 2” x 3” or 3” x 4”* 

• 

The barrel must be located within 28” (71cm) of the downspout to 
use the fill hose provided.

• 

The ground under the barrel must be level and firm.  A solid surface 
base of wood, pavers, or stone is recommended.

• 

If the surface is not level, use a shovel or rake to grade the surface.  
Check by placing a level on the rim of the barrel before continuing. 

Place the barrel in the intended location with the front facing out.

1. Mark the front of the barrel.  This will be the side with the spigot facing 
out.  The spigot should be located on a flat or evenly curved surface without 
ridges or features that can affect the water seal.

2. Hold the fill hose in position between the barrel and the downspout and 
mark the water inlet location on the rim of the barrel.  This mark can be at 
the back, right, or left side of the barrel. 

Check that the hose can reach horizontally from the rim of the barrel to the 
downspout.

*Water capture percentage is reduced with 3”x 4” downspouts

Installing the fill hose seal

1.  Locate the water inlet mark on the rim of the barrel (from Step 4).  

Measure down 3” (76mm) and mark the center for the water inlet hole.  
Make sure the inlet is located on a flat or evenly curved surface: avoid 
ridges or other features that could affect the water seal. 

2.  Drill a single hole using the (MEDIUM) 1-1/2” hole saw included in the set.

3.  Insert the fill hose seal into the hole

 Pinch the seal into a “U” shape 

for easier insertion.

Some areas prohibit the 

use of rain barrels. Please 

check local regulations 

before installing.

The FlexiFit diverter helps discourage mosquitoes, pests, and 

algae-causing sunlight from entering the barrel.  The diverter is 

easy to remove from the downspout and the kit includes a winter 

hole cover.
The FlexiFit diverter offers many advantages over conventional 

top fill rain barrels that commonly flood with heavy rain, require 

permanent modifications to your downspout, and use unsightly 

overflow hoses.

Option B: Mid-height spigot with bottom drain

1.  Mark the hole for the spigot. Find the front of the barrel, measure up 

12” (30cm) from the bottom of the barrel and mark the center for the 
mid-height spigot hole.

2.  Mark the hole for the drain. Measure up 3” (76mm) from the bottom 

of the barrel and mark the center for the drain hole. 

 

If you plan on 

connecting a garden or soaker hose to the drain fitting, we recommend 
that the drain be located 6” (15mm) off center, to the left, or right side 
of the spigot to give clearance for filling the watering can.

3.  Drill 2 holes on these marks using the (SMALL) 1-1/4” hole saw included 

in the set.  

You may need to remove the plastic cut out from the end of 

the hole saw after drilling the first hole.

4.  Insert 2 threaded rubber seals into both the spigot and drain holes. 

Pinch the seal into a “U” shape for easier insertion.

5.  Thread the spigot and drain into the seals until the hex collars sit firmly 

against the seals.  

Soapy water or hand lotion will reduce friction and 

improve fit.

DO NOT CUT THE DOWNSPOUT UNTIL READING THE ENTIRE GUIDE! 

The FlexiFit diverter redirects water from your downspout to the barrel 
and automatically passes water through the downspout when the barrel 
is full of rainwater.

The diverter is installed in a hole that is cut in the downspout.

1.  The hole must be cut at the correct height for the diverter to work 

properly.

2.  If the diverter is installed too low, the barrel will not fill properly.

3.  If the diverter is installed too high, water will overflow from the rim 

of the barrel (this only applies to open top barrels).

IMPORTANT: There are two ways to install the diverter depending on the type 
of barrel you use.  If the barrel is a sealed container without a lid or screen, the 
diverter can be located at the same level as the rim of the barrel or higher.  This 
will improve the filling efficiency of the diverter.

If the barrel has a removable lid or screen, the center of the diverter hole must 
be drilled 3”(76mm) below the level of the rim of the barrel to prevent water 
from leaking from the lid seam or screen.  The diverter will not work if it is 
placed below the level of the water inlet on the barrel.

The diverter provided in this kit is not for use with round downspouts.
