  • Water Pressure Test Guage

    What kind of test guage do you guys use. All of the supply houses around me only sell those cheap a** Jones Stephens guages that i believe to have about a +/-20psi tolerance and that annoys me. For the past year or so i have kept them in the original packaging and just taken them back and swapped for a new one after the 10 or so uses i have gotten. This is usually when something happens with the spring and the fail to re-set at zero. I am looking for something with a little more quality, durability, and mostly dependability. I need something that i feel is accurate and i have faith in. There is a big difference in 75psi and 90psi.

    They give you a new one after using it?

    I don't like the cheapies either. So I went and got some liquid filled ones for longetivity & durability.

    Except they went out of tolerance pretty quickly also.

    Back to the cheapies.

        I make mine up using oil filled SS WIKA gauges. I have a bunch of valves or will use a yellow jacket hose depending on what I am doing.

          First time I've seen a $1857.00 pressure gauge.

            A glycerine filled HVAC / Refigeration Suction (low pressure) gauge should do just as well the range is Vac to 150 PSI and they are user calibrated.

            Marks is without a doubt the best (remember what he does for a living) but you can use a much cheaper gauge like this ($30)...

                If you want a rather low cost, but good gauge for use on garden hose bibs, these items should work pretty well. This is far superior to the hardware store POC gauges.

                Fitting (very simple and basic) : http://www1.mscdirect.com/CGI/NNSRIT...MT4NO=57969506

                Fitting you may like better: http://www1.mscdirect.com/CGI/GSDRVS...00000083955252
                and then use one of these with it: http://www1.mscdirect.com/CGI/GSDRVS...00000083955486

                Gauge 1: http://www1.mscdirect.com/CGI/NNSRIT...ber=4354&mode=

                Gauge 2 / better quality: http://www1.mscdirect.com/CGI/NNSRIT...ber=4358&mode=

                In case the links don't work the main web site is WWW.MSCDIRECT.COM
                MSC Industrial Supply Co., Inc. 1-800-645-7270

                Their catalog numbers are 56479611 which is a 2-1/2" 0-200 PSI lower mount basic pressure gauge. The picture shows the same but as 0-300 PSI. A better gauge is 56453533

                Their catalog number for the adapter fitting is 48764039
                It's a simple brass fitting of female 3/4 NH garden hose to female 1/4 NPT.

                You may want to go for fitting 48764120 and use a 1/2 - 1/4 NPT brass bushing such as 02203719

                Please keep away from KRAPPY gauges like this one. While a well known brand it is made in China using slave labor:

                  Re: Water Pressure Test Guage

                  Thanks that is exactly what i had in mind. Question: I expect that a faulty prv with some thermal expansion i could expect to see pressure climb close to 200psi. Don't think i have seen it go over 200, but would you go with the 200psi scale or 300psi scale? Don't you want the expected pressure to be closest to the middle of the range for accuracy? Maybe i will get one of each. I like the Wika's! and don't mind spending the money. They look like they will last.

                    Are you kidding? $2K is the low end of high quality test gauges.

                      I got a few of mine from Watts $10, Some from Barnett's which I really liked and forgot to order more, $6

                      and ones I buy as I keep forgetting to bring mine in to keep from freezing.


                      Got a broken one in the truck right now; that's two in 3 months.

                        Might be a good idea to go with say a 0-160 or 0-200 and a 0-300 gauge.

                        Yes, A gauge reads best in the 1/3 - 2/3 part of the range. You want to aim for about 1/2 of full scale as your nominal pressure when selecting a pressure gauge.
