The Flow Doctor Water Pressure Gauge worked perfectly. Just got the main water shutoff valve and main line coming into the house replaced and a pressure valve installed. The plumber did a great job and out of three plumbers, the price was reasonable for the work done. The pressure coming into the house was over 100 psi which is way too high and can be damaging to the plumbing. The call to plumber started with a weird whining noise that progressively got louder and I traced the source to the main water pipe and valve coming into the house. Consequently, we called the plumber the very next day and had it repaired by the following afternoon. All said and done, the repair in combination with installing the pressure valve resolved the strange ghostly whining in the pipe, and the plumber cut the pressure back to 50 psi. That said, I purchased the Flow Doctor Water Pressure Gauge to check the pressure myself and low and behold, it was exactly 50 psi per the plumber's recommended setting. So now I have validated their work and I am impressed with the accuracy of this little gauge. I did see a few folks state that their Flow Doctor leaked excessively. I had no issues. I do know that it would leak like a sieve if you did not use the supplied rubber washer. As long as you pop that on before you connect it to your mains water or hose line, you should have no leaks. Enough said! I will write a follow up review should the Flow Doctor fail down the road. But consider no news to be good news. I found it to be a handy and accurate little tool and it is a very good idea to ensure that your water pressure is where it should be to protect your plumbing. A small investment for some peace of mind and a lot cheaper than having a major leak somewhere in the house due to excessive water pressure!

It's a pressure gauge. It screws directly onto a garden hose thread as -delivered, although it is packed with adapters to fit onto sink and other threads. I did not try any of those. Compared to measurements from a neighbor's similarly inexpensive water pressure gauge, it is within about 2 lbs. I have no definitive standard to test it against for absolute accuracy, so I can only give it 4 stars. It does seem well made. Threads are clean and smooth. It doesn't leak.
