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
The red pointer is supposed to indicate the maximum pressure reached while the gauge is connected.

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.

3/4 in. Plastic Water Pressure Test Gauge is rated 3.3 out of 5 by 42.
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.

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

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.

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!!

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...

Rated 3 out of 5 by from The drag hand is of limited usefulness, but the gauge appears to read water pressure just fine. ... 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.

Rated 5 out of 5 by from good value for a quick check for the price, this gauge worked well for me. I have a professional liquid filled gauge but I couldn't find it and got this one to get an inspection completed. I read the other reviews on this product and was doubtful if it would be up to the task. After using it at the inspection site I found my pro gauge at home and compared the readings at my home. This product had the exact same readings as my liquid filled gauge.

Rated 4 out of 5 by from Showed me exactly what I needed to know ... This Watts water pressure gauge is an easy and inexpensive way to determine residential or commercial water line pressure. I connected it to an exterior faucet and it confirmed my suspicions about elevated pressure. After repairing my pressure problem I simply left the gauge attached to my faucet for a few weeks to be sure my water pressure remained in a safe range. Good product which does exactly what it implies it does.
