what does the red arrow indicates

when I checked the water pressure of my house the black arrow indicated 65 and the red one 125. what does this mean?
Asked by: babaraffi
I have to agree with the commenter above and recommend some skepticism regarding the reading supplied by the red arrow, I own three watts pressure gauges and am familiar with their use and function, using a watts gauge attached to an outside spigot I determined the incoming pressure at my house was a over 100 psi and certainly the cause of the jet engine style noise emanating from the walls whenever a shower was underway. I installed a zurn-wilkins pressure reducing valve which brought the p.s.i. down significantly, however using the watts gauge and the red surge indicator i determined that the p.s.i. was still spiking at times, ( in this instance the arrow worked though i verified the situation by observing the gauge as the hot water heater was actively heating the tank contents,) realizing that i was likely dealing with thermal expansion i installed an expansion tank, tank is pressurized to 60 psi matching the reducing valve set to the same level. The tank is installed vertically directly above the cold water inlet supported by a shelf, below the tank is a "t" on which is mounted a watts pressure gauge, i was shocked to find the surge needle still registering pressures over 100 p.s.i. , again i observed the gauge during and after a shower was occurring inside, as the tank was filling the red needle was rising though the black dipped during the shower and held steady at 60 psi following, i discovered that even the slightest vibration causes the surge needle to climb, tapping on the copper pipe below or operating the valve on the inlet line some 36" away from the gauge all cause the surge needle to climb unaided by the black needle. Indeed in resetting the surge indicator if you contact the black indicator at all you will notice a rebound effect. One possible explanation is that the gauge does not function optimally installed in the horizontal position, however I have been unable to locate any literature indicating a preferred installation method and since i am pleased with the performance of the gauge otherwise i haven't felt the need to redo the piping to allow a vertical orientation.

How do you get the arrows to zero before you attach it to the line. Mine are showing 20 psi and it's not hooked up.

Asked by: anne
If your BLACK arrow is at 20 psi and not 0 when not connected to a faucet, you have a bad unit. Take it back to HD and exchange it for another.

I saw other reviews and was not too sure if I wanted to buy this unit. Home Depot has a great return policy, so I figured I had nothing to lose. Purchased in December 2016. I connected it to my faucet on the laundry tub and turned on the faucet on full. It went up to about 75 psi. I flushed a toilet and it dropped to 60 psi and then backup. Did not leak. Used 3 different times and worked great!!

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.

Bought one and discovered the package was opened when I got home. Hooked it up and found that the black needle would not go below 90psi. Took it back. Got another one and checked it to make sure it was set to 0, which it appeared to be. Took it home, hooked it up and this one will not go below 130psi. It is impossible to reset the unit - if I use the red needle to push the black one to 0, the black one just goes back to 130psi as soon as it is released. I'm going to return this one and go some place else to get a WORKING unit.

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.

Rated 5 out of 5 by from Mine worked OK. I bought this one to figure out the cause of the copper tubing banging and water heater relief valve leaking shortly after installing. Surprisingly the gauge showed 120 PSI, so I asked my plumber friend if that is even possible, and he brought his gauge, the one he uses on his job and it showed exactly same pressure. Don't know how long this gauge will last and frankly, I don't think I'll be using it a lot in the future, but it worked when I needed it and it was dead on.

The only reason I recommend it is because it's inexpensive and accurately measures pressure. The two start rating is for the useless red limit needle. As others have said, the needle moves far too freely (with no resistance) and every bump from the black pressure needle sends it flying. You'll think your pipes are about to explode. With more drag and it would work much better. Simple manufacturer fix is in order.

This Watts Pressure Test Guage proved to be a very Useful and Informative tool by Showing the changes in Our Hot Water Recirculating system. Having added a 2nd Hot Water Heater as a Back Up / Buffer tank to Warm the Cold Water going into the Main Hot Water Heater, I was concerned about the Water Pressure being created by the New Check Valves being added to the Closed system. I also had added a Recirculating Pump recently to the Return Lines since the Gravity Loop was not doing the Job. As a Result of the Results Shown by this Guage, I concluded that the Old Check Valve must have Failed, leaking Cold Water into the Gravity loop; 30 years of Hard Water will do that. Now I know.... 40 Pounds of City Water Pressure, Spikes of Hot Water Lines Pressure up to 80# ... steady Pressures throughout the Day as Tenants use the Hot Water and the Hot Water Heaters come on. Handy Tool that Works Well.
