Watts 2-1/2" Hose Connection Water Pressure Test Gauge, 3/4" (20 mm) HT Hose Connection, Copper Alloy, Black Enamel Steel Case, Red Indicator Hands, ASME Type B Accuracy

We're on community water and needed to have a pressure regulation valve installed. After the plumbers left I noticed they'd set the pressure way too low. Instead of calling them back and spending a lot more money on another call, I ordered this and adjusted the pressure myself back to something reasonable. Where our water comes in, just after the regulator, is what looks like a regular garden hose spigot for draining the pipes. I screwed this into that spigot, turned it on and adjusted the pressure on the valve. It was very simple. There were no leaks and no problems. The only issue is that I really just needed this gauge for this 2 minute project so now it's going to sit on a shelf in the utility room. It's not something I will likely ever need again. But if someone else does it's here to borrow I guess. So, it worked fine, no leaks and saved me having to call the plumber back for a simple adjustment.

Works as expected.

Does what is advertised, max needle a bit to sensitive to be useful

Solved my water pressure issue.

Inexpensive and worked great to measure our water pressure…I’m installing a computer-controlled sprinkler from Irrigreen. (Check them out...Their system automatically adjusts flow to match your lawn boundary!). The Irrigreen system needs between 40-80 psi and this was an inexpensive way to measure it. The gauge worked well. I used it once and I’ll probably never need it again, but for a nominal cost I got the information I needed.

I needed to regulate my water pressure and this worked perfectly. It's easy-to-use with no leakage and easy readability. Watts is a good brand and can be trusted with good quality. Trust me to trust this product.

Obviously this is a really simple device, so there is not much to say. The gauge fits on a normal hose bib without any leaks. The pressure readings match my other pressure gauges, so I would call it accurate. Responses to other reviews: Re needle on wrong side of stop - I doubt this is a manufacturing issue, this sounds like a delivery issue. I suspect it was dropped in delivery causing the needle to jump over the stop. Eitherway, it is a simple fix since the clear face can be easily removed and the needle manually pushed over the stopper. Re red high pressure needle is loose - This is supposed to be this way, if you push back on the black needle you can see how little resistance it takes to move it. Obviously if you set the red needle too tight, it would interfere with accurate readings. Again, eitherway, the red needle is counterbalanced, so while you can bump it easily, it won't move on its own.

The one I bought years ago is great. This one has a loose hold needle that others have also complained about. I cut out a small piece of plastic from the packaging, sliced a notch in it, and slipped it between the hold needle brass grab handle and the clear plastic case. This provides enough consistent friction to keep the hold needle from moving under surges or vibration.

القطعة ممتازة ومقاسها (3/4)، ميزتها تركب مباشرة على أي بزبوز، أو تقدر تشيل الوصلة وتركبها على مخفض الضغط. بس ملاحظتي أن الإبرة الحمراء "فضفاضة" بزيادة، ومع أي اهتزاز أو ضغط بسيط تدور وما تثبت في مكانها.

Works very well. Quality made and the red dial works great (stays in place for maximum pressure). Excellent for monitoring increase in water pressure in closed system.. Surprising how a hot water heater will raise the water pressure (because of backflow preventer on municipal system)

Used this to adjust our PRV at our house by hooking it up to a hose bibb. Worked great, well worth the price paid.

This gauge works well but I only rated it four stars because it is a little bit cheaply made. If it had a glass face instead of poor quality plastic I would have rated it five stars. No complaints with the performance though.

Good to have so you know what your house water pressure is.
