It will be close to the inside wall where the water supply passes into the house from the line going towards the water meret.

There is usually a main water valve that comes into the house, locate this valve and turn it down. Installing a pressure reducing valve after water main valve will allow for adjustment of water pressure to proper setting.

A relief valve is in a system that builds pressure to make sure it doesn't build up too much pressure and burst the tank or line. The water heater has one, an air compressor has one, any thing that builds pressure will have one at some point. Pressure reducing valve regulates how much pressure is available in the line. Water line from the city may have 100 lbs. in it but there is a reducing valve right inside the house so that the pipes in the house only get 40 lbs. in them.

You could adjust your PRV(Pressure reducing Valve)to 25 PSI

pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.

nothing, its just terminology why A pressure relief valve is a safety device to prevent over pressure in such things as compressor receivers. A pressure reducing valve drops the pressure to the requirements of the user or tool. Such as a demand valve on scuba gear.

A pressure regulator is a control valve that reduces the input pressure of a fluid to a desired value at its output.

A pressure valve is usually installed on water systems to prevent excess water pressure from destroying fixtures or other plumbing components. When the pressure exceeds the valve ratings the valve opens and releases water/pressure from the line.

Too much pressure or defective valve.

Pressure reducing valve reduces the pressure of fluid upto a predetermined pressure in this case downstream pressure will be obviously lower than upstream pressure but in case of pressure regulating valve it will regulate the pressure( either increase or decrease) depending on the requirement of system at that time.

check your pressure regulator valve or house pressure .Replace fixture stop and ballcock assy also r&r flapper

The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.

it is the valve which reduce the pressure.

Pressure safety valve-are the valve who are designed such that it can control the pressure , like in the water blowers etc,and Temperature safety valve are those who are used to regulate the temperature like, in water boilers.

Really you should not do this yourself unless you are relatively experienced and have the proper tools. Shut off the water at the meter. Drain the pressure from the system. Get the Outside diameter of the pipe on each side of the valve. You will need 2 pressure couplings and a new valve in between. You will need room to install your pressure couplings at least 2" of straight pipe on both sides of valve.

Generally there's a spring holding the valve close, when the internal pressure is great enough, the valve opens - until the pressure drops. In some applications, there's a weight holding the valve closed.

Area water authority could have increased water main pressure, no or defective expansion tank in house main water line if house has a backflow preventer installed, or defective /not properly set pressure reducing valve.

On Ur main cold water line on house Looks like a brass cone

A pressure regulator is a valve that works in a way that at a certain pressure it automatically stops the flow of a liquid or gas .

The purpose of a pressure relief valve in a geyser is to release the pressure created inside due to evaporation of water.
