Can you replace a well tank yourself?

Replacing a well tank is a major project that requires some plumbing skills. With proper planning and preparation, some homeowners opt to replace their well tanks themselves instead of hiring a professional. There are a few key considerations when deciding if a DIY well tank replacement is feasible.

What’s involved in replacing a well tank?

Replacing a well tank involves disconnecting the old tank, removing it, installing a new tank, reconnecting the plumbing, and disinfecting the well. Here are the basic steps:

1. Turn off power to the well pump and drain the old tank.
2. Disconnect all plumbing to and from the tank.
3. Remove the old tank – this usually requires unbolting it from the concrete base.
4. Install the new tank on the concrete base and re-bolt it down.
5. Reconnect all the plumbing to the new tank.
6. Refill the tank and purge air from the lines by running all faucets until water flows freely.
7. Disinfect the well and plumbing using chlorine bleach before using the water again.

Proper disposal of the old tank is also required. The whole process typically takes 6-8 hours with 2 people working.

What skills and tools do you need?

Replacing a well tank successfully requires some plumbing expertise. Here are the key skills and tools needed:

• Plumbing skills – cutting and gluing PVC pipes, using fittings, understanding water pressure and flow.
• Electrical knowledge – safely disconnecting electrical connections to the pump.
• Lifting capacity – well tanks weigh hundreds of pounds when full and require 2+ people to remove and install.
• Tools – pipe wrenches, PVC cutter, hacksaw, torch, channel locks, screwdrivers, voltmeter, etc.
• Safety gear – glasses, gloves, sturdy shoes.

If you lack experience with plumbing and electrical work, replacing a well tank may be quite difficult. Many homeowners choose to hire a professional well or plumbing contractor rather than risk an improper DIY installation.

What are the costs?

For a DIY well tank replacement, your main costs are:

• New well tank – $200 to $600 depending on size and material.
• Misc parts & fittings – $50 to $100 for couplings, glue, bolts, etc.
• Renting any tools you don’t own – $50 to $200 for large pipe wrenches, saws, etc.
• Disposal fees – $50 to $100 to properly dispose of the old tank.

So the total DIY cost can range from $350 up to $1000 in some cases. Hiring a professional typically costs $1000 to $2500. So DIY can provide big cost savings if you have the skills.

Should you do it yourself?

Here are some pros and cons of replacing a well tank on your own versus hiring a pro:

DIY Replacement	Hiring a Professional
Pros: Cost savings Learn new skills Cons: Labor intensive Risk of mistakes May need tool purchases/rentals	Pros: Experience doing installations Proper tools and skills Warranty on work Cons: Higher cost

As the table shows, DIY well tank replacement offers cost savings but requires technical skills and labor. Hiring a pro costs more but provides experience and warranties.

How can you prepare for a DIY replacement?

If you decide to take on replacing your well tank yourself, advance preparation is crucial. Here are some tips:

• Study up – Read guides and watch videos to understand the full process before starting.
• Inspect carefully – Check the pump, pressure switch and piping for issues before buying the new tank.
• Have helpers – Plan to have at least one extra set of hands for the removal and install.
• Gather tools/materials – Buy or rent any tools you need. Have all fittings, glue, bolts, etc. on hand.
• Check regulations – Verify any codes and permit requirements in your area.
• Schedule time – Don’t rush – allow plenty of time in case the project takes longer than expected.

Proper planning helps ensure a smooth installation process and optimal function of the new system.

Step-by-step DIY well tank replacement

Once you are fully prepared, here is an overview of the step-by-step tank replacement process:

1. Turn off power to pump – Locate the circuit breaker or switch and disconnect power so the pump does not run dry during work.
2. Drain old tank – Open the drain valve at the bottom of the old pressure tank and let all water drain out.
3. Disconnect plumbing – Using pipe wrenches, disconnect all pipes to and from the old tank. Have a bowl handy to catch remaining water.
4. Remove old tank – Unbolt the tank from the concrete base and rig up a makeshift lever system with boards and rope to hoist it up. Have an extra person help slide it out.
5. Install new tank – Lower the new tank into place over the base. Re-bolt it down securely.
6. Reconnect plumbing – Glue all fittings with PVC cement. Replace any corroded pipes as needed.
7. Refill system – Turn power back on to the pump. Open valves and faucets and let water run until all air is purged.
8. Check for leaks – Carefully inspect all fittings and connections for any leaks.
9. Disinfect system – Add chlorine bleach and run all faucets to disinfect. Let sit for 24 hours before using water.
10. Confirm proper function – Verify the pump kicks on/off appropriately and there are no pressure issues.

With good preparation and care taken during each step, a DIY well tank replacement can be completed successfully. But don’t hesitate to call a professional if any issues come up.

Conclusion

Replacing a well pressure tank is a major undertaking, but can be completed by a knowledgeable DIYer. The key considerations are having the necessary plumbing skills, tools, helpers, and plenty of time. Advance preparation is essential.
