Question

What factors cause changes in water pressure?

Answer 1

At your home, a water utility supply line into your home is typically only 1 inch in diameter. This 1 inch pipe is split multiple time to route water to every watter connection in your home i.e toilet, shower, sink, outside faucet. Each of these connections is typically only 1/2 inch...so the more open lines a home has the lower the pressure will be, as the incoming pressure from the water company is held fairly constant.

Answer 2

Well it depents on the source of water supply, if it provides higher pressure then more water will pour out the hose. Water consumers also affects it, if there are consumption occuring from the same supply then the pressure gets lower.. . Altitude doensn't affect that much.

Answer 3

Could be a leak. The water flowing in to the hot water heater. Maybe the valve for the hot water heater is not opened enough.

Answer 4

In your house? Most cities have water towers. As the tower gets fuller the pressure goes up. As you use the water it gradually goes down. Most cities have automated systems when the tower or pressure gets so low pumps are activated to refill the tower. This is the basics. Alot more involved in the treatment and other processes.
