Future-Proof Your Garage: The Importance of Using the Right PVC Pipe Size for Electrical Installations
If you’re planning to install power to your new or existing garage, it’s crucial not to cut corners when it comes to the size of the PVC pipe you choose. At AC Electric, we often see customers making the mistake of using smaller pipes to save money, only to face costly upgrades later. Here’s why spending a little extra now can save you a lot in the future.
The Common Pitfall: Undersized PVC Pipes
Many homeowners and contractors opt for half-inch PVC pipes because they are cheaper. Currently, a 10-foot stick of half-inch PVC costs around $7.00. In comparison, a one-inch PVC pipe might be around $12.50. The price difference might seem significant when purchasing in bulk, but considering the labor costs for trenching and installation, the total expense difference is minor.
Real-World Example: The Case of the Undersized Pipe
Let’s talk about why picking the right pipe size is super important. Here’s a story about a customer we helped recently.
The customer had 3/4″ PVC running from his house to the garage; about 20 feet away. We installed it for him over a decade ago before there was a driveway put in and “future-proofed” it by installing 3/4″ pipe rather than 1/2″ for the few circuits he wanted in his garage.
Last week he contacted us because he wanted to install a Tesla charger for his new vehicle which he recently purchased. The garage power ran a decade ago was not enough to install the maximum output the charger could provide (70-amps). If he wired it in on a 20-amp circuit, it will work…but…the amount of power available dictates charging speeds. To understand more, read this article:

Despite the limitations, we found a way to make the 3/4″ pipe work. We gave him enough power to install a 50-amp charging system for his Tesla, plus extra circuits for his lights and garage outlets.
Why Size Matters
1. Accommodate Future Needs: As electric vehicles (EVs) become more common, the demand for higher electrical capacity in garages is increasing. Installing a larger PVC pipe now ensures you can easily upgrade your electrical system to support such devices without retrenching or major modifications.
2. Avoid Limitations: While we managed to maximize the three-quarter inch pipe for our customer, having a one-inch pipe would have simplified the process and provided more flexibility. A one-inch pipe could have supported a 100-amp circuit, easily accommodating a Tesla charger and a hot tub.
3. Increase Resale Value: Homes equipped to handle higher electrical loads are more appealing in the real estate market. Prospective buyers appreciate the foresight and the convenience of not needing immediate upgrades for their electrical needs, especially with the growing popularity of electric vehicles.
The Cost-Benefit Analysis
Investing an extra $20 to $50 on larger PVC pipes during the initial installation can save you hundreds or even thousands of dollars in the long run. The ease of pulling wires through a larger pipe means fewer complications and reduced labor costs for any future electrical work.
Final Thoughts
At AC Electric, we advise our customers to future-proof their electrical installations. Don’t restrict yourself with half-inch or even three-quarter inch pipes. Opt for at least a one-inch PVC pipe to ensure you’re ready for any future electrical demands. The slight increase in upfront costs is a small price to pay for the flexibility and peace of mind it offers.
