Expansion tank are essential to a properly functioning plumbing system. They help regulate pressure fluctuation and protect your plumbing fixtures and water heater from damage. This blog will provide a step by step guide for bonding and assembling an expansion tank. Let’s learn how to bond and assemble an expansion tank.
Expansion tanks: What are they for?
Before you start the installation, it is important to understand what an expansion tank does. In a closed-system plumbing system, water expands as it heats up. Without an expansion vessel, pressure can build, causing damage to plumbing or the water heater. An expansion tank will absorb the excess pressure to prevent any issues.
Gather the Tools and Materials
For a successful installation of an expansion tank, a few materials and tools are required. These include an adjustable ratchet, pipe cutter or hacksaw; emery or sandpaper; flux, solder and a soldering torch.
Locate the Location
Find the ideal location to install the expansion tank. It should be placed vertically and near the water heating system. There should be enough clearance and space for future maintenance.
Shut down the water supply
Before you begin any installation, shut off water to the plumbing system. Locate the main shut-off water valve and close it.
Install the Bonding Clamp
In some regions, it’s necessary to bond the tank expansion to the plumbing for safety. Attach a clamp to the tank to secure it to a grounded surface. Consult local codes and regulations for compliance.
Prepare the Pipes
Use a pipe-cutter or hacksaw to cut a section near the water heater. This pipe will be connected to the expansion tank. To ensure proper soldering and fitting, clean the ends with emery or sandpaper.
Install the Tee Fitting
Apply flux on the cleaned ends of both the expansion tank’s intake and the pipe. Insert a tee between the two fittings to ensure a leak free connection. Join the fittings to the pipes with a soldering iron and solder. If you’re using threaded connectors, you can wrap Teflon around the threaded ends, and tighten it with an adjustable screwdriver.
Connect the Expansion Tank
Attach the inlet of the expansion tank to the open end tee. Use pipe dope or Teflon Tape to ensure a tight, secure connection.
Test for Leaks
After installation, turn on water and check the connections for leaks. If you notice leaks, tighten any connections or add additional Teflon tape or pipe dope.
Verify Proper Pressure
It’s important that you check the expansion tank after it has been installed to ensure it is working properly. Check the pressure of the air inside the expansion tanks using a tire-pressure gauge. The pressure should match manufacturer’s specifications.
Conclusion
Installing and gluing an expansion tank to your plumbing system is a vital step in maintaining its health and preventing damage caused by pressure changes. This blog provides a step-by-step guide to install an expansion in your plumbing system.
During the installation, it is important to adhere to local codes. Maintain and inspect your expansion tank regularly to ensure optimal performance. Enjoy the benefits for many years of a balanced and protected plumbing systems.
