Hello--
My house is almost 12 years old. We recently had the bathroom Hot water supply line under the sink pop off causing a "minor" flood.
Anyway, long story shorter--the house water pressure is around 105psi.
The plumber who found it high said he couldn't get back to replace the Watts 1" water pressure regulator until Tuesday. Is there any potential problems? I hear water pipe knocks at certain times when the toilet for example has filled and water stops to the toilet.
Thanks in advance for your help. I have had problem sleeping because I do not know if the entire plumbing pipe system is going to leak all over the place.

There can be problems if your pressure is that high but at least you know he is coming back to fix it. In the meantime you can close your main when you go to sleep or need to run out. Are you on city or well water?

We're on city water. If I shut the water off does the pressure reduce even if we do not open a water line? The water heater is still on also--any problems with that? Am I just shutting off the water in case there is a leak? What is my main concern--solder joints?
How long can plumbing be at this type pressure without a problem? When the pressure regulator is replaced and the pressure is around 50-60 psi, will I have any future (hidden)problems caused by this period of over pressurization?
So many questions, so many unknowns in my mind, so much lack of experience.
Thanks for any helping experience.

High House Water Pressure

--------------------------------------------------------------------------------

Hello--
My house water pressure was recently found to be high--105 psi--the Watts Pressure regulator has died--the plumber is busy and said he would be out on Tuesday. (5 days after the diagnosis) Is this an emergency that requires Immediate attention? Are my pipes going to blow? Will I have unknown small leaks even after the problem is fixed? What do I have to worry about? And longer term be concerned about?
Everything seems okay at this point except for a few "knocks" in the plumbing especially in the morning when it is cold outside.
Really appreciate the help!
Thanks,
Ron

You can stop fretting, chances are good that your system won't blow up. 105 PSI is too much for house pressure,(45 to 50 PSI is the average) but your system should hold up until the plumber returns to replace the PRV valve.
Try not to shut off faucets so fast that they water hammer. With the extra water pressure this puts a strain on elbos. Kick backand relax, you're going to be fine. Tom
