What You'll Learn
Drilling a hole in a plastic water tank
Prepare the Tank and Mark the Drilling Spot:
Start by determining the size and location of the hole you need for your specific application. Mark the spot on the tank's surface using a paint marker. Ensure the marked spot is flat and level, and avoid any curved or weak areas of the tank.
Choose the Right Tools:
Select a hole saw that matches the required hole size. A hole saw is the recommended tool for drilling through plastic tanks as it cuts cleanly and reduces the risk of cracking. Secure the hole saw into the chuck of a drill motor.
Drill a Pilot Hole:
Place the point of the hole saw pilot bit directly on the mark you made on the tank's surface. Start the drill motor and apply moderate pressure to slowly drill a pilot hole through the plastic tank wall. Stop drilling once the pilot hole is completely through the plastic.
Water Cooling and Lubrication:
Coat the hole saw and the surrounding tank surface with water by spraying them with a water-filled spray bottle. The water will act as a coolant and lubricant, reducing friction and heat buildup during drilling.
Drill the Full Hole:
With the hole saw and plastic adequately cooled and lubricated, continue drilling with moderate pressure. As the hole saw teeth approach the end of the cut, reduce the pressure on the drill handle to prevent cracking or damaging the tank.
Final Steps:
Once the hole is complete, pull the hole saw out of the tank. Sand the edges of the drilled hole with fine-grit sandpaper (120-grit or finer) to smooth out any rough edges and remove plastic particles. Ensure all sharp edges are removed to prevent damage to the tank or any seals.
It is important to note that drilling into a plastic water tank requires caution. Incorrect drilling methods or using inappropriate tools can result in cracks or damage to the tank. If you are unsure or uncomfortable with the process, it is advisable to seek professional assistance to avoid any potential issues.

Installing a faucet on a plastic water tank
Step 1: Plan Ahead
Before purchasing a plastic water tank, it is important to consider the intended use, location, and how long the water will be stored. This will help ensure that the tank is suitable for your needs. Additionally, if you plan to install a faucet, inform the manufacturer during the design process, as some tanks may not support faucet installation after purchase.
Step 2: Gather Tools and Materials
The installation process requires a few basic tools and materials. These include a suitable faucet, common woodworking tools for cutting, and the necessary fittings such as bulkheads or through-wall fittings. Bulkhead fittings come in various materials and styles, so choose the appropriate type for your tank. Standard bulkhead fittings are typically suitable for plastic tanks, but bolted and self-aligning bulkheads may require a different size hole to be cut.
Step 3: Prepare the Tank
Plastic water tanks often feature "fitting flats," which are flat spots designed for adding bulkhead fittings. Identify the location for the faucet and mark the spot for the hole. Before cutting, ensure you know the size of the bulkhead fitting and the corresponding hole size. It is recommended to practice cutting on a scrap piece of plastic or wood to ensure accuracy.
Step 4: Cut the Hole
Using common woodworking tools, carefully cut a hole in the marked spot. If the tank is full, consider placing a strong plastic cup or container inside the tank over the screw point to catch any leaking water. As soon as the tank is perforated, the water will generate pressure and push against the hole, slowing or stopping the leak.
Step 5: Install the Faucet
Insert the bulkhead fitting into the hole, following the manufacturer's instructions. Ensure that the fitting is secure and properly aligned. Then, attach the faucet to the bulkhead fitting, screwing on any necessary washers, nuts, or other components.
Step 6: Finalize the Installation
Once the faucet is in place, carefully tighten any connections, being careful not to overtighten, as this can damage the gasket, fitting, or tank wall. Perform a final quarter to half turn after the locknut feels secure to ensure a tight seal. Test the faucet to ensure there are no leaks, and make any necessary adjustments.
By following these steps, you can successfully install a faucet on your plastic water tank, providing direct access to the water stored within. Remember to take your time, work carefully, and ensure all connections are secure to avoid leaks.

Connecting two plastic water tanks
Most plastic storage tanks have "fitting flats" built into their design. These are flat, level locations added to a storage tank to allow for the installation of additional fittings, such as bulkheads, which enable extra plumbing connections. Fitting flats are often located towards the top of the tank, but can also be found along the tank sidewalls, including at the bottom. They are usually at a distance of 90° to each other, and sometimes 45°.
To connect two water tanks, you can use piping to join the tanks at the bottom or the top. Connecting tanks at the bottom requires less plumbing work and only one overflow and outlet tap for the entire system. To do this, position the tanks with at least six to twelve inches of spacing between them. Then, measure and record the length between the outlet ports. The width measurement of the tank's outlet port and its style should also be noted. Female NPT type ports are common on plastic water tanks and can be directly threaded with male NPT-style plumbing and connector fittings.
Connecting tanks at the top can be done by linking the tanks at the same outlet level on their sides with piping. Isolation valves should be installed at the tank outlets to control the release of water. This setup allows for tanks to fill up at the same time.
It is important to note that professional installation by a licensed plumber may be required in certain locations, so it is recommended to seek their expertise to ensure a successful installation.

Installing fittings on a plastic water tank
To begin the installation process, you will need to cut a hole in the tank wall using common woodworking tools or a hole saw. The tank wall thickness can vary depending on the brand, quality, and intended use of the tank, so it is important to take this into account when cutting. Once the hole is cut, you can install the chosen fitting.
Bulkhead fittings, also known as through-wall fittings, are a common choice for plastic water tanks. They come in a variety of materials, such as PVC, CPVC, PE, PP, and stainless steel, and in different styles, including threaded, bolted, self-aligning, and garden hose adapters. The installation process for a bulkhead fitting involves sliding the gasket over the body of the fitting, inserting the fitting body into the hole from the inside of the tank, applying thread tape, and then securing the large nut on the outside of the tank. It is important to hand-tighten with a wrench and be careful not to over-tighten to avoid damaging the gasket and the fitting.
Another option for installing fittings on a plastic water tank is to use spin weld fittings, which are inexpensive, or a hot air plastic welder with a welding rod. This method involves spinning a fitting of like plastic at high speed and pressing it into the plastic until friction melts them together. However, this method may require specialized tools and may not be suitable for the average person.
It is important to note that installing a faucet or any other fitting on a plastic water tank should be done professionally to avoid leaks and ensure a proper seal. Plastic water tanks are preferred due to their versatility, ease of cleaning, transport, and insulation capabilities. They also offer more water storage capacity and are safe for health and usage.
