Pressure Regulator

I just ran new copper lines for a small sink, including a water heater. When I turned on the water a small amount came out of the faucet's cold tap, under pressure, then no more came. I took off the faucet's filter before I turned on the water. If I turn off the water, then turn it back on, the same thing happens. I checked the filter screen in the pressure regulator and it's clean. Is there something going on internally in the PR that could be causing this? As far as I know, there isn't any blockage in the copper lines. There's nothing else in the system except PR, WH and sink. Oh, there are taps for a washing machine, but no washing machine. What's going on? Sounds like classic "backwards check valve" to me. If it was crud/blockage, you'd get some water then nothing more, ever, no matter how many times you turned the water on and off. |

If it was crud/blockage, you'd get some water then nothing more, ever, no matter how many times you turned the water on and off. Tend to agree altho would like to know more about what was actually done and where. It may be coincidental, but pressure regulators _can_ fail I think this is most likely. It's a case of "it was working when I took it out, and now doesn't when I put it back. There was a period of several months between the first and the 2nd event, and it is 20-25 years old now so maybe that's the best reason. If it did fail, I can take it apart to see if I can repair it for future use. Do you have any stories of pressure regulators you'd like to share? (I know, you didn't ask but I'll tell the story anyway.. ) A day or two after the youngest daughter was born after having been in the new house only a few months, we have no water. To compound matters, the pressure regulator is not to be found inside the house anywhere or even at the meter opening and the builder wasn't present at the installation and doesn't even remember who the plumber was. To add even more joy, it is raining steadily for two days and no sign of letting up. In order to get water, I cobbled up a bypass w/ a garden hose from the meter to the outside hydrant on that side of the house while starting to dig to find the obstruction. The regulator was buried inline in the trench about 5 ft from the meter for some absolutely unknown reason and it was the culprit having failed shut. Needless to say, it was relocated into a more accessible location... -- charles |
