Step 2Building the Valve Assembly
To build the valve assembly:
1. Screw the 3/4" MPT x MHT (Male Pipe Thread to Male Hose Thread) adapter into one end of the threaded valve.
2. Screw the 3/4" nipple into the other end of the threaded valve. Screw the other end of the nipple into the 3/4" PVC Schedule 40 Bushing Spigot x FIPT (Female Internal Pipe Thread).
3. Insert the assembled parts into the Drain Waste Vent Flush Bushing (2" to 1-1/2" reducer) and then into the 2" Tee.
About sealing the joints:
I found that friction was all that was necessary for the valve assembly. You can also use plumbing tape or PVC cement for the non-threaded joints.
NOTE:
For the single barrel design, you will not use a Tee in the assembly.
NOTE:
I chose to use this design over other designs I found online because of the volume of throughput. Other designs using different spigots or hose bibs would reduce the volume of the water coming out of the barrels as well as the gravity fed pressure. With this design I am able to have 2 hoses connected both receiving almost the full 3/4" diameter of volume through to the hose threads (see the final picture of the volume through the valve assembly). The bottleneck in this system is not the valve or piping, but the 5/8" hose or attachment at the end of the hose.
Also, have younger kids who love to help in the garden, the plastic valve offered the ease of use I wanted for them to be able to fill their watering cans or water guns.
