Questions & Answers

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.

Is the Watts 3/4 in. Plastic Water Pressure Test Gauge DPIWTG available at any store locations around the Columbus Ohio area.

Asked by: Bill
Go to www.homedepot.com and search for the gauge and it will tell you if there are any in stock at your location.

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.

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.

Rated 1 out of 5 by from Max Pressure Needle Is Useless! I needed to monitor the peak pressure over a week. The first time that I checked the gauge the red max pressure needle showed that the gauge had max'd out overnight! As another reviewer has mentioned, the ultra-light weight red needle is bounced across the dial at the slightest tremor, rendering the indicated value useless. For single instance/live monitoring, this gauge works fine. Avoid if checking for pressure highs...

Plastic, so keep that in mind if its something you'll be using all the time. Otherwise worked fine for me. Confirmed what I thought. Needed a new preesure regulator installed. Worth $10

The drag hand is of limited usefulness, but the gauge appears to read water pressure just fine. It's really meant for short term testing. Seems to be reliable for finding your nominal pressure. The red drag hand is really loose and can actually walk up on its own if the pipe vibrates enough. Another post suggested pushing some silicone grease or similar stuff under the brass knob to dampen it a little. That seemed to work. I used this gauge to determine what size expansion tank I would need on the water heater that I had to install. I recommend that when you connect it to a hose faucet that you open the faucet valve just slightly. Just crack it open enough to read pressure. With the valve open wide, I quickly discovered that it really exaggerated even small instantaneous pressure spikes. Like when someone flushes the toilet. My nominal pressure is about 70 psi, but when even something like the toilet tank fill valve closed, the needle would overswing and take the drag hand instantly to around 140. Sometimes even higher. By only slightly opening the faucet valve, the pressure changes were registered a little slower and needle would not overswing near as much.

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!!
