Water Pressure Glycerin Filled Gauge Kit, All Purpose, 6 Parts Kit, 0 To 200 Psi, Standard 3/4" Female Garden Hose Thread Plus 5 Adapters To Test in Multiple Locations Indoors and Outdoors

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!

No complaints. Got the job done.

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.

Nice kit. Decent quality for the price point.

Works perfectly for checking water pressure.

This gauge is easy enough to use, and told me what I needed to know. I used it by itself on my outside spigots (just like connecting a hose) to test the pressure of the water entering the house (all three faucets registered 65 psi). I also screwed it onto the cold and hot spigots for the upstairs washing machine. Again, just over 60 psi. Then I used two of the included adapters to check the pressure going to a lavatory and shower in the master bath (again, just over 60 psi). I had to use pliers to tighten these adapters enough so they wouldn't leak and give me a false low reading. So with this gauge I was able to ascertain that the low flow coming out of the shower panel I just bought and installed is not being caused by anything other than the shower panel itself. I suppose it's possible (but not probable) that this gauge is faulty and is just giving me the same reading for wherever it's attached, so I should get a second opinion with another gauge just to be sure.

This was very accurate as I had a measurement at the street from the water company that I was able to compare to my outdoor spigots. The delta was about 3 PSI, which is very reasonable.

Yes there are cheaper ones, but this has all the adapters you need, a clear chart for which adapter to use on which type of outlet (no need to try all different ones), and a sturdy case to store everything in for later. Total novice needed this to convince my landlord there really is a water flow problem here, but I'm glad I bought a good one because it'll be useful for all sorts of plumbing troubleshooting that arises in older buildings. It saved me a big headache to find out for myself that my "low water pressure" was not pressure but flow (indicating a blockage somewhere). By looking up my shower valve on the Moen website, and finding that I have 45psi of pressure at all the water points in my place, I could see that the shower valve should put out 5 gallons per minute with the shower head removed. It was only dispensing 1 gallon per minute at 45psi, and having that data finally got the landlord to take some action.
