Leaking Pipes Joints
I have 120psi water pressure at my house and am having a hard time
getting a complete seal on the water connections of my tub faucet. I had to use a couple of brass adapters to go from a 1/2" copper line to a 3/4" brass connection, so I have more joints than usual. I am using teflon tape on all the joints and keep getting a little seepage around the joints. The previous connections on the old faucet with 1/2" connectors were what I think are called slip joints, using cone-shaped rubber washer. The brass fittings do not have any kind of compression joint or washer to seal off the water, except on the end that connects to the copper line, where a compression ring seems to be sealing just fine. The other connections depend on the sealant on the threads. Should I be using permanent pipe sealer at the threads that do not connect directly to the faucet and the water line? Or is there something better than teflon tape that I should use on the joints? I am wrapping about 2 layers of the teflon tape around the male connectors, starting at the first threads of each joint. |

Most household fixtures are not rated for120 PSI. Besides havering trouble with your fittings, I'm surprised that you aren't damaging your fixtures. Have you considered a Pressure Reducing Valve to bring the pressure down to something reasonable, like 60 PSI? |

Everybody immediately jumps up and tells you that you have to have a pressure reducer. I have 120 psi water pressure and have had hardly any problems. I have one hose bib that I have a problem keeping washers in, but that hose bib is over 50 years old, and I suspect it just needs to be replaced. So don't get in a swivet over people telling you what you absolutely have to do. As far as the leaks, you might try using the liquid pipe dope. Put on a good thick coat and screw the threads up tight. Bill |

Step 1: Install a Pressure Reducer. No reason to be above 60 or so PSI. Most are about 50 PSI The leaks are not due to pressure, a proper joint can easily handle it. Make sure the connections are clean, no dents or dings, tape is wrapped properly. |

The heavy (pink) teflon tape would likely be a better choice. I solved my problem with regular teflon tape. |

And NEVER use "compression fittings" - you know, the ones with the brass "olive" that gets cranked onto the pipe by turning the compression nut. They WILL seepwhen used on hard copper lines - almost guaranteed. You might never see a drip, but months later the connection is all green. |

And there are some mysteries there, like why there is a washer or seal of some kind when going from copper to brass. Teflon tape should work, but I also agree with your suggestion of trying pipe dope instead. More likely, he's doing something wrong, like not making them up tight enough. |

" http://ogradyplumbing.com/blog/under...ater-pressure/ If a PRV is required at 80 PSI for new builds and inspections, then a PRV makes sense in *any* situation where the pressure exceeds 80 PSI. One could argue that in older homes, a PRV is even more important because fixtures and/or fittings may not meet the more stringent modern codes. |

When I sold a rental property the home inspector said the water pressure was to high ~ 85 PSI. He gigged me and stated I needed a PRV installed. The house didn't have one. I opened all the faucets, hose bibs, ran the water, dishwasher, etc. -- took pressure out of the pipes and then took my own reading at a hose bib ~ 20 feet from the street meter.. Argued the inspector had a faulty meter gauge. Buyer accepted that so nothing was needed. The pressure had been tested during the day when most folks were at work so pressure would be high. Release that pressure and you get a different reading. At least in my case it did. Would 120 PSI blow a PRV on a water heater? I don't know. |

In my experience, when the water pressure feeding a home or business gets over 80psi, the safety valve on the water heater can leak because of water hammer. The pressure pulses when water is turned off can exceed 150psi and the valve will leak a bit. The more times it happens, it can deteriorate the valve sealing surfaces. I've had to install Watts pressure regulators in homes and businesses where the water pressure was too high. The regulators are set at 50psi at the factory and that's where I always left it. In a home, the pressure relief valve on the water heater will dribble and the faucet seals plus toilet tank valve can leak. In a business like a restaurant or convenience store, the high pressure and pulses not only damage the pressure relief valve on the water heater but the Sloan flush valves in the restrooms. Also the solenoid valves in ice machines, soft drink dispensing machines, dish washing machines and water cooled refrigeration units can be affected. We had one customer who owned a night club wind up with a $1,000.00 water bill one month because of a leaking toilet. The dumbass employees didn't inform the owner about it. The water pressure was in excess of 100psi going into the building and we installed a pressure regulator to bring it down to 50psi. I've seen a business that had 120psi water pressure coming in and spikes in excess of 200psi. It was damaging all sorts of things in the convenience store. It turned out that the existing pressure regulator had failed. It was an inch and a half water line coming in and we found the regulator inside a wall under a sink. Me and my brother had a lot of fun fixing that one. ヽ(€¢€¿€¢)ノ [8~{} Uncle Sink Monster |

As soon as they shut the last hydrant, that pressure will increase to over 200psi for a few seconds. At that time, weak pipes will balloon, weak joints will explode apart, wash machine hoses will rupture, valves will fail, toilet tanks may shatter, and water heaters & boiler tanks may explode if the PRV is not working properly. |

Lucky I had just stepped into the garage. Shut the ball valve off and went inside to tell the bride how lucky we were on Super Bowl Sunday She was on the phone to her friend standing at the kitchen sick. Heard her say the sink faucet just started dripping and leaking. I opened it, closed it and it stopped. Told her to buy a new water heater (jokingly). We have a PEX manifold system. I guess, only a guess, the pressure reversed and water passed via the faucet somehow. Replaced the heater and had to open the kitchen faucet after to let all the air in the lines out. Still don't know why the faucet dripped, but it hasn't happened since. It was a one time thing. Maybe something to do with the PEX manifold. |
