Water Filter Flushing and Purging — Final Checks and System Purge

How to Replace a Well Pressure Tank · Step 10 of 10
In this video
With the unit fully assembled and connected to the pipeline, slowly open the main water inlet valve about halfway. Allow water to run through the system for at least 15 minutes to flush out any carbon fines and air. As the housings fill, press the red pressure relief buttons on top of the bracket to expel trapped air until water begins to spurt out. After flushing, fully open the water valve. Check the pressure gauges to ensure the displayed pressure matches your home's normal incoming water pressure. The system is now operational.
Goal: Flush and purge the system for initial use
- For the first use, you need to open the 1/2 water valve and rinse for at least 15 minutes.
- Press the red button to expel the air from the filter.
- The pressure displayed on the pressure gauge should match your incoming water pressure.

FAQs
What are the most critical safety steps I must take before beginning to replace my well pressure tank?
Absolutely always turn off the power to your well pump at the main electrical panel first. Then, fully drain the entire water system to relieve all pressure. This prevents electric shock, water damage, and injury from pressurized components.
How long should I expect this well pressure tank replacement to take, and what's the approximate material cost for a DIYer?
For a beginner, plan for 2-4 hours, assuming you have all tools and materials ready. The material cost, primarily for the new pressure tank and fittings, can range from $200 to $600, depending on the tank size and brand, plus a few dollars for tape and rags.
Why is correctly pre-charging the new well pressure tank so important, and what pressure should I set it to?
Pre-charging with air prevents the tank from becoming 'waterlogged' and ensures your pump cycles efficiently, extending its lifespan. Set the tank's air pressure (when empty) to 2 PSI below your well pump's 'cut-in' pressure (the pressure at which your pump turns on).
Which specialized tools are absolutely essential for replacing a well pressure tank, beyond basic household tools?
You'll definitely need a sturdy pipe wrench (like the 16-inch self-adjusting one mentioned) for plumbing connections, a tire pressure gauge to check the tank's pre-charge, and a water pressure gauge to monitor system pressure. Slip-joint pliers are also very helpful for various fittings.
