Water pressure in house?
Per an earlier discussion, I have been trying to ensure that I will
not have a future problem with T&P valves in my house... bought a pressure gauge at the Despot last night on my way home from work (there's a rant in there, but not pertinent) hooked it up, system pressure is about 68-70 PSI falling to 60 PSI with a faucet open and momentarily spiking to maybe 78 PSI. This is measured in the basement, at about the level of the T&P valves. I left the gauge connected overnight and the hot water heater went through at least two cycles and the telltale did not rise. Everything I've read says that pressure should be regulated to 60 PSI or less, I am guessing since I did not experience a rise in pressure when the water heater cycled that I don't have a BFP on the main water line (actually, the weird thing is I don't even know if I have a meter, I can't see one unless it is buried underground) so "by the book" I should install a pressure reducer set for 60 PSI but since a pressure reducer would also act as a BFP I would then need to add an expansion tank as well. Question is, is this really necessary or is 70 PSI OK? I'm not looking to spend a lot of money on plumbing but if the high pressure could potentially cause an issue I guess I should take care of it. thanks, nate PS - the Home Despot rant. Found a Watts brand "test gauge" at the Despot on my way home from work (pressure gauge with telltale, screwed into a female garden hose fitting) bought it, took it home, found that the telltale was bent so that it didn't catch the gauge needle. Went to a different Despot near my house, they didn't have a gauge to exchange it. Drove back the other direction to go to the original store, told the guy I wanted to exchange the gauge, well either he didn't speak English well enough to understand or just didn't know that you could do a straight exchange, so he refunded my money and I had to buy another one, meaning I had to stand in line again for 20 minutes to check out... grr... probably wasted a good two hours on this whole exercise. And then I had to run out again to get matches (see my other post from this morning) so I didn't even get home until close to 9 PM. I'm really starting to get sick of plumbing stuff. |

You should have a pressure reducing valve on your main water line where it enters your house. Usually shaped somewhat like a bell. Tnere is a screw in top that will increase/decrease the pressure. Unfortunately I don't remember which direction you need to go. Maybe someone else remembers. Try only one quarter or one half revolutions at a time. |

Bob Because in some locales (like right here at my house), the unrestricted water pressure may spike to 100-125, and even if you don't mind your pipes slamming, some appliances and devices might have issues with. |

Same thing here. I have a 120 PSI gage on the line and daytime pressure was just fine. One time I happened to look at the gage in the middle of the night and it was pinned because with low water usage the public water supply pressure drifts up. I used to frequently change o rings and washers in valves. I installed a regulator and can't remember the last time I had to tinker with anything. |

Bob- Hide quoted text - - Show quoted text - Municipal water supplies commonly have pressures way higher than is good for residences. Town of Colfax, WA found out about PRs the hard way. They built a new tank up on the canyon rim, put it in operation and promplty blew fittings all over the downtown zone. I dunno the altitue difference but it is considerable. Somehow they escaped any penalties and wouldn't help pay for the PRs that everyone had to install. Harry K |

Pressure is one of two factors. Don't keep the temperqture too high for safety and like that T&P valve problem. My house has a water pressure gauge and regulator. The pressure is set at 60 psi. In my memory at several different houses I had custom built, never had T&P valve problem. |

In my memory at several different houses I had custom built, never had T&P valve problem. I think the original problem was simply a bad T&P valve. I've had a cup under the overflow pipe (never did properly route it to the sink, although that's on The List...) and the gauge on the drain valve ever since I fixed the drain valve (I think that was Tuesday?) and the cup is bone dry and the telltale is at about 81 PSI. So I guess I don't have any problems at this time, well, other than the toilet that makes a horrible noise while it refills which I'm sure is completely unrelated and I can fix that. I was told that there is no pressure reducing valve supplied by the city with the meter, and I sure can't find one inside the house anywhere. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |
