How to Replace a Well Pressure Tank · Step 7 of 10
In this video
Lay the old tank on its side and use wrenches to remove the copper pipe fitting assembly. On the new tank, remove the protective plug from the threaded outlet. Apply pipe thread sealant liberally to the male threads of a new 1-1/4 inch to 1-inch reducer adapter. Thread the adapter into the new tank and tighten it securely with wrenches. Then, apply sealant to the threads of the old copper pipe assembly and thread it into the newly installed adapter, tightening it firmly.
Goal: Plumbing
- Use a galvanized steel reducer instead of black pipe to prevent rusting.
- Be careful not to cross-thread the fittings when installing them into the tank. They should thread in smoothly by hand before tightening with a wrench.

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.
