      Answer This Question

      To use the water pressure test gauge, simply thread it onto a standard 3/4 in. hose connection, such as an outdoor faucet or washing machine valve. Turn on the water slowly and read the pressure directly from the gauge. When finished, turn off the water and remove the gauge.

        Will this thread onto a typical shower arm where the shower head would screw on to t water pressure there?

        Answer This Question

        No. It will thread onto a 3/4" hose thread like an outside hose bibb.

            Can this be placed permanently year round in an outdoor irrigation hookup? Seems to be leaking less than a year after installation.
            ByMay 16, 2025
            1 Answer | 
            Answer This Question

            The gauge is not recommended for outdoor year round use.

              Has anyone left this meter permanently hooked up via a Tee mount? Or should I include a shutoff valve on the Tee before the meter?
              ByFeb 6, 2025
              1 Answer | 
              Answer This Question

              There is not a problem to installing it on the branch of a tee permanently. And it's up to you whether to install an isolation valve but, is always a good idea so the whole system doesn't need to be shut down to change it out later.

                Is this gauge filled with some sort of liquid? I have an older one that seems to have leaked some clear viscous liquid. I hadn't used it in some years.

                Answer This Question

                No. The gauge is not liquid filled.

                  I used it and another gauge to set my house water pressure. It's an accurate gauge.
                  by
                  The gauge is accurate and fits standard hose bibs perfectly. Unfortunately, water filled up behind the glass display almost immediately. While it gets the job done for a quick check, the build quality on the internal seals seems a bit hit-or-miss.

                  Good quality, but...
                  I just bought this item and opened it up. The item quality seems very good, but the manufacturer incorrectly installed the red needle: it is on the low side of the black needle and between it and the lower stop pin. This makes it the "lowest reading", not the highest reading. Other than that, the gauge seems to be of good quality. However, I cannot recommend it.

                    Peak Reading is Valuable
                    This easily screwed onto our standard garden hose fitting with my fingers. I left it attached for a full 24 hours. I really like the peak reading feature provided by the red needle. It allowed me to see the current pressure was staying around 48PSI while also showing that there was at least one peak reading around 62PSI. Please see attached image.

                      simple fix
                      I bought this after reading several reviews that said the red high-pressure hand was too loose. When I installed the gauge I wrapped the shaft for the red hand under the knob with a couple of loops of sewing thread and tied a knot. This was adequate to dampen the movement of the red hand but still allow it to be moved by the black hand. I also found that adding more than a couple of loops of thread created too much drag for the black hand to move, which resulted in a low pressure reading.

                        simple water pressure gauge
                        I used this to measure my pressure from an outdoor spigot, and then removed the outside connection and added it to my hot water heater line next to my expansion tank so I can always monitor the pressure by the heater. Some people complain the max dial is too loose - it's designed that way and works perfectly. I carefully set it right next to the black dial, and then let it be. After a week my max pressure was about 82psi. Easy to read dial, numbers are large and legible. Only complaint is the spigot attachment was extremely difficult to remove. It had some sort of glue, not sealant. But it works and measures accurately.

                          The gauge works good for checking your pressures. I used it to sett the pressure on my sprinkler system and to monitor pressures from my well. I did leave it on my faucet during a rain storm and it got water on the inside of the meter lens, otherwise I would give it 5 stars.

                          Installed easily. No leaks. No pressure indicated. Needle on opposite side of post from zero psi. Wanting to check pressure and the low cost of gauge... attempting to fix was easy. Clear lid came off with little effort. Managed to push needle in opposite direction, slipping and catching, until resting at zero psi and... it worked. Confirming neighbors psi of 92. Not sure how the needle got on wrong side of stop and under tension. Gauge has worked since indicating slight pressure changes. No sign of package tampering. Just got the bad one I guess.
