How do you plumb a water tank?
You need to vent (allow air in and out when filling and emptying) the tank. If you do not the tank will be damaged.
You can not hook a garden hose to the tank, this is pressurized water and will damage the tank.
What fittings do I need?
This will depend on how you are running the tank. It is recommended to use plastic fittings because the tank has plastic fittings, metal fittings can damage the threads.
How do you get the correct fittings?
All of the threaded fittings we carry are NPT (National Pipe Thread Standard).
1/2" Female NPT Fitting - You will need to get a male fitting to use with this.
1 1/2" Female NPT Fitting - You will need to get a male fitting to use with this.
1 1/4" Outer Diameter x 2" Long x 15/16" Inner Diameter Smooth Pipe
Pipe sizes do refer to physical dimensions, but the plumbing industry standard for the sizes of pipe is not always as straight-forward as measuring the pipe. Measuring the pipe will oftentimes mislead you into choosing the wrong pipe, so do take care. The "pipe thread size" as shown in column 3 of the table below is measured and based on the inside of the pipe. But, to actually determine the size of a pipe, the outside diameter of each pipe or fitting must be measured and compared to the table for size identification. For example, a 3/4" NPT pipe thread has an outside diameter of 1.050 inches. Each thread size has a defined number of threads per inch (TPI). The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI (threads per inch) and OD (outside diameter) of the thread are required for positive identification of thread size because several sizes have the same TPI.
Male threads: Measure the outside diameter of the large portion of the thread at "A"; Find figure nearest this dimension in column 1 or 2 of chart. The dimension in column 3 will be your nominal pipe thread size. |
Female Threads: Measure top diameter of thread at "B"; Find figure nearest this dimension in column 1 or 2 of chart. The dimension in column 3 will be your nominal pipe thread size.

What fittings do you sell?
When you add fittings to your water tank this will increase the length of the tank, be sure to account for this when deciding on a tank.
