Rain Barrel

Purpose:

The purpose of this project is to collect rainwater into barrels to be used at a later time to water the garden/grass.

Research:

I spent a lot of time looking at different designs, how people built them from very easy setups (1 barrel) to multiple barrels (6+). The most important thing to note is that if you are going to use this for a garden, ensure that you get barrels that are food grade safe. Sometimes these barrels are used for chemicals which can kill your garden, or be absorbed and ingested (if you are growing food - like I am)

Prep:

After obtaining your rain barrel(s) make sure that you take some time to clean it. Mine used to hold soy sauce (it stinks!)

2 x 55 gallon food grade safe barrels

2 x 2" DWV MIP Adapter

2 x 2" DWV Street Elbow 90 degree Spigot x Hub

1 x 2" PVC Pipe 8 feet

2 x 2" PVC Tee (t section = 1 1/2" opening)

2 x 1-1/2" x 3/4" PVC Schedule 40 Bushing Spigot x FIPT

2 x 3/4" Short Galvanized Nipple

2 x 3/4" PVC Ball Valve

2 x 3/4" MPT x 3/4" MHT adapter with red valve

1 x Plumber putty

1 x 8 feet downspout extension

1 x downspout adapter with twist on (Connects downspout to extension)

1 x 10ft downspout

1 x downspout elbow

Bag of self tapping screws for eavestrough

Tools Used:

Drill

Utility knife

Drill bits

hacksaw

measuring tape

Construction screws

pencil

I chose to go with a 2 valve approach as I will be leaving one connected permanently to a hose, and wanted to have the option of filling up jugs, water guns, etc without having to disconnect the hose.

1. Screw the 3/4" MPT x MHT adapter into one end of the threaded valve.

2. Screw the 3/4" nipple into the other end of the threaded valve.

3. Screw the other end of the nipple into the 3/4" PVC Schedule 40 Bushing Spigot x FIPT

4. Insert the assembled parts into the 1 1/2" section of the PVC Tee.

5. Repeat steps 1-4 for second valve

6. Cut a piece of PVC tube

7. Connect valves together with PVC tube

1. unscrew one of the bung holes in each barrel

2. screw in DWV MIP Adapter into the bung hole

3. Connect elbow to the DWV MIP Adapter

4. Connect assembled valve piece (from previous step) to the elbows to join the barrels together

Note: I connected this upside down to make it easier to see what it looks like when it is connected. Ideally, this will be done after placing the barrels in place.

There are lots of different ways to build a platform for these. You want to make sure that the barrels are high enough that gravity will do its magic to help keep the pressure up.

I have created an Instructable already for creating the platform. Instead of re-creating the steps, please go to the link below to see how the stand is made:

It is important to consider what to do if you have too much water.

To overcome this, I drilled out a small hole on the side of the barrel that will act as an overflow. I will be connecting some tubing to this and running it away from the house to the grass.

Using a small drill bit, I drilled several small holes near the top of the barrels to allow air flow in and out to help with the pressure

1. Determine where you will place the hole in the barrel

- I did this by simply doing a mock up of how I would like it and then made a note of where to drill

2. Using a drill, drill a hole into the barrel

3. I did not have the right size bit, so I drilled a couple holes and used a utility knife to shave the edges to make it fit

4. Using some force and a screwdriver, I connected the downspout extension into the hole that I just drilled

1. Determined where I would cut into the downspout

2. Using the hacksaw, cut out a section of the downspout

3. Connect the elbow to the current downspout

4. Using the screws to secure the connection

5. Attach 10ft downspout to elbow

6. Using the screws to secure the connection

7. Attached the plastic extension to the end of the 10ft section

8. Using the screws to secure the connection

Connection to barrel and downspout completed!

This is a must do!

Once you have everything assembled, you want to make sure that there are no leaks, otherwise you will not benefit from this. I simply stuck a hose in the overflow hole and started to fill up the barrels. I did notice a small leak where one of the bung holes connects with the DWV MIP Adapter.

To overcome this, I used plumbers putty around the hole. After doing this, retested the water and it is all sealed now.
