Because someone is using water somewhere else. For instance, if you are having a shower and someone flushes the toilet, the water going to the shower is decreased because some is going to the toilet now.

What does water pressure mean?
Water pressure refers to the pressure of water in a system. In a home it will be 30-50 psi typically and this is governed by the municipal pressure or by a well tank.
Who makes John Deere tractors lawn sprinklers?

Who invented ironing boards lawn sprinklers?

Why if you are connecting a sprinkler line from the main water how come you don't have water pressure on my sprinklers?
Friction losses are seldom taken into account which cause drastic pressure drops
What caused pipes to rattle when you turn on the outside sprinklers?
High water pressure could be the reason for pipes to rattle when you turn on the outside sprinklers. You may need to have a reducer valve installed.
Does bood pressure fluctuate?
It does
What is preaction sprinkler system?
A sprinkler system employing automatic sprinklers that are attached to a piping system that contains air that might or might not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers. Preaction systems are typically installed in areas where water damage due to accidental discharge of the sprinklers or breakage of the piping is a concern, or damage in the sprinklers and piping due to freezing. There are three types of preaction systems: non-interlock,single interlock, and double interlock. non interlock: water flow to sprinklers upon fused sprinkler or detection single interlock: water flow upon detection Double interlock: water flow only when detection and sprinklers detect fire
How do automatic sprinklers work?
It uses a programmed switch box that can be set to come off and on at certain times. The switch, when on, regulates electricity that shuts on/off valves to water. The sprinklers turn or operate from the water pressure itself. Some people have this system rigged to solar panels to use the sun's energy.
Why would the temperature gauge fluctuate?
Possibly the thermostat is opening and closing with the water pressure changes. Could be low on coolant also.
What does it mean to fluctuate?
The dictionary meaning for the very fluctuate is "to rise and fall irregularly in number or amount". Something like blood pressure or waves on the ocean can fluctuate.
How does dry riser sprinkler system works?
The heat of the fire causes sprinklers to trip, releasing nitrogen or some other gas held under pressure in the system through the sprinklers. This action activates a dry pipe valve within the sprinkler system which releases fire protection water which has been restrained within the system, through the sprinklers with the intention of dousing if not extinguishing the fire.
Should my Blood pressure fluctuate during the day?
Yes.
Oil pressure drops raises?
Correct. The oil pressure does fluctuate throughout the RPM range.
Can 2 irrigation valves be operated by single zone?
Yes, as long as your water pressure is high enough to meet the requiremnts of the sprinklers, drip or bubblers associated with both valves.
Should fusible link sprinklers be used in a deluge system?
No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
