Questions and Answers for HOME-FLEX 15 psi Gas Pressure Test Gauge

A:  Hi, Steve - Yes, although some tests may have different requirements per local codes and/or the Authority Having Jurisdiction (AHJ).

A:  I would suggest a better device for measuring differential air pressure. The device we use to test differential air pressure across a fan or filter is a Dyer Magnehelic Manometer. I would guess the static pressure across a torpedo heater is less than 2"WC but ask the manufacturer before purchase. This meter can be mounted on the heater for continuous readings. If you go this way you will need the kit with two Brass serrated hose fittings, hose and mounting plate to attach the meter to the heater. All available on Amazon.

This suggestion is assuming you want to know the heater fans output in inches of water column over time to know when to clean the filter. Hope this helps, ET

A:  Hi, Rob71 - This pressure gauge is simply to determine loss of pressure over a period of time. You would have to use a manometer.

A:  Hi, Joseph - No, you'd need a manometer for that.

A:  These gages are meant to monitor air pressure in the closed piping system prior to hooking up to the gas meter and appliances. Contact a licensed HVAC contractor or your natural gas supplier to check the gas pressure in your connected piping system.

A:  No, sorry. A manometer is scaled to read the pressure of the gas piping system in inches of water column. Our gauge is scaled in psi in 0.1 psi increments and is intended to detect a loss of pressure during a pressure test.

A:  it is leagal in Massachusetts to use this gage as a gas mamometer

A:  Hi, Giovanny - Yes.

A:  Hi, Bob - The pipe thread size is 3/4" female as shown on homedepot.com.

A:  I saw no caution on the packaging regarding gas use only, therefore, i assume liquid pressure testing is allowed with this tool.

A:  That would be experimentation. This gauge has never been tested for such use. This gauge is designed to indicate a loss of pressure when used with a gas, not a liquid. Gas is defined as a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume (unlike a liquid). I recommend that you use a water pressure test gauge approved for the type of test that you want to conduct.

A:  Hi Gene, That is one possibility, but you do not want to put your test pressure against any appliances or regulators. I invite you to give me a call, so I can hear more about your system before I can make a recommendation. Often times we put a tee in the system, just so we have a place to fit our test gauge. We can be reached at (661) 257-3923. We are here from 8-5 Los Angeles time M-F. Ask for Jon

A:  I got it and figured it out..... I got a 3/4 piece of pipr and screwed it in to the pipe going into the house after I disconnected meter (gas had been cut off of course by gas company), turned the valves off to the water heater, furnace and gas dryer the filled the lines with 10 pounds of compressed air and let it sit and sprayed connections for leaks ( did not find any and gas company came back out and turned gas back on).
