Review on 🔍 DANCO Gas Test Gauge 0-15 psi at 1/10 Increments, Chrome-Plated: Accurate and Reliable Pressure Measurement for Gas Systems (94352) by Ryan Judy

The first valve showed 4.5psi when not plugged in so I sent it back and got another one. The second valve works great! Before using it I put pipe grease on the valve and gauge guard based on other reviews. I then connected it to a 3" nipple and cap and increased the pressure to 15psi as a test. Very small overall volume, so this is a very revealing test. After 24 hours it's still exactly 15psi where it started. Now I have confidence in the sensor and if it shows a leak I know I need to fix something. If the first valve worked I would give it 4 stars.
