Review: Helped me set water pressure - We're on community water and needed to have a pressure regulation valve installed. After the plumbers left I noticed they'd set the pressure way too low. Instead of calling them back and spending a lot more money on another call, I ordered this and adjusted the pressure myself back to something reasonable. Where our water comes in, just after the regulator, is what looks like a regular garden hose spigot for draining the pipes. I screwed this into that spigot, turned it on and adjusted the pressure on the valve. It was very simple. There were no leaks and no problems. The only issue is that I really just needed this gauge for this 2 minute project so now it's going to sit on a shelf in the utility room. It's not something I will likely ever need again. But if someone else does it's here to borrow I guess. So, it worked fine, no leaks and saved me having to call the plumber back for a simple adjustment.
Review: Water Pressure Gauge - Works as expected.
