Excessive pressure may damage pipe joints and internal parts of cheap faucets. The old PolyB pipe is very susceptible to breaking under excess pressure. In most cases, I see no reason for house pressure to be in excess of 50 psi.

What is R1-1 zoning mean?

R1-1 zoning typically refers to a residential zoning classification that allows for single-family homes on individual lots. The "R" indicates residential use, while the "1" often signifies that only one dwelling unit is permitted per lot. The "-1" may indicate specific regulations or conditions, such as minimum lot sizes or setbacks, which can vary by municipality. Overall, this zoning aims to maintain a low-density residential character in the area.


What is pressure valve?

There are various kinds of pressure valves. Perhaps the 2 most common in homes are the PRV (pressure regulating valve) which is on most incoming water pipes from a city supply. This valve limits the pressure entering the home system, bringing it down from city mains pressure. The second is on every hot water tank, and this is a relief valve, which will open up if the pressure in the tank becomes too high and vent the excess water down the drain.

Is home electricity 3 phase?

No, in North America most homes are wired to a single phase transformer. That transformer is connected to a three phase power grid. Some of the newer apartment buildings and condominium complexes have three phase systems in them. Their voltages are 120/208 as compared to a homes single phase connection of 120/240 volts.AnswerSome European countries, such as here in Cyprus, have three-phase residential supplies as standard for some reason -can't quite figure out why it should be necessary, though!
