Review on 🔧 Ingersoll Rand 23474653 Pressure Switch - Optimized for Single Phase Compressor SEO by William Auditore

My compressor had a leak from this switch and all troubleshooting led to it. After replacement, the leak stopped until the next cycle. In a nutshell. After investigating the problem further, I saw a check valve on top of the tank. I did a little research and yes that is why the switch is leaking. This may not be your situation, but if it's still leaking after replacing it, try replacing the valve at the top of the tank. This is called a check valve.
