Q:I have backflow prevention valves on my hose bibs. The gauge I have doesn?t work. Will this one get a reading with the backflow valve?
by|Jan 25, 2023
1 Answer
Answer This Question

A:  It should measure the pressure. What it won't do is show a drop in pressure if the backflow prevention valve is really tight as the higher pressure at the gauge won't relieve back into the system if the pressure in the house goes down.

    Q:If I am watching the gauge, will I see black needle push the red needle to its highest point if someone else is doing adjustments and turning water on and off? I ask, because the red needle seems hypersensitive and jumps up higher than black needle moves.

    Answer This Question

    A:  I think what is happening is that there is little or no friction on the red needle so if the black needle moves fast, it will bounce the red needle higher than the actual pressure.

    by|Dec 7, 2022

      A:  Yes

      by|Dec 10, 2022

        A:  The easily rotated red needle is a marker you use to analyze pressure changes. It is not meant to gauge water pressure. That's the job of the black needle. However it is so loose I found it to be of little help and simply wrote down the indicated pressures during checks throughout the day.

          A:  Yes, this would be correct as it is sensitive to water pressure.

          by|Dec 5, 2022

            A:  Yes, you should. It may be hypersensitive base on the orientation of the gauge.  Don’t expect it to be an exact, more of an in the moment close estimate.

              Q:Is it normal for the clear dial part of the gauge to fill with water?
              by|Sep 30, 2022
              2 Answers
              Answer This Question

              A:  Hi, I don't think so. In my tests, there was no water in the dial itself.

              by|Oct 9, 2022

                A:  No, it is not normal for water to appear inside the gauge. A gauge with water inside the gage housing or display would be considered to be defective.

                    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.

                          I work for Gulf Coast Realty LLC in Fort Myers, Florida. I had a customer buying a high end condo and they were worried about the water pressure. I put it on the washer hook up tap and it showed 53lbs slightly above the recommended amount. It gave everyone piece of mind and allowed my transaction to go through with confidence.

                          I only needed one gauge, but I bought two. This Watts 'IWTG' in the Plumbing department and I bought a Rain Bird brand from the Irrigation department a couple of aisles over. I wanted to test the calibration between the two as I repaired our home's pressure reduction valve to reduce the inside pressure to about 50-55 psi. I hung the two gauges on both front and rear hose bib faucets and never did the two gauges read more than a 2-3 psi difference. I'm satisfied with this Watts gauge, and I recommend it as a good value. And I really only needed one of these, as it turned out.

                            I purchased this water pressure test gauge after having a faulty water pressure reducing value replaced. As the reducing value was going out, our water pressure would jump to extremes. That along with defective PEX pipe resulted in three leaks in our home. The plumber that replaced the pressure reducing value had a test gauge similar to this one. His however was heavy and of much better quality than this one. He recommended I buy one and test my pressure monthly. I looked for one similar to his but this was the best could find. It only takes a few minutes to hook it up to the front yard water line to check the pressure. This gauge is plastic and feels kind of flimsy but I've used it four months and it's hold up nicely.

                            It works
                            The pressure gauge has a thread to connect to test points (like on backflow prevention devices), and it has an adapter attached to connect it to a hose bib. It took a lot of force to unscrew the adapter. I stripped the adapter. It seems like it was glued in. I used PTFE tape to re-attach it. I took it apart. I think how it works is the water fills the flat copper tube, causing it to inflate, which pulls on the gear thing which rotates the needle.
