More than likely it is the size of the (supply) pipe from the pump to the system. If you have a larger supply going to the house and less demand (one facuet on vs. 4 sprinkler heads on) the presure will be greater in the house. If you increase the size of the supply to the system it will help. Just remember presure and volume work in concert with each other. GOOD LUCK!
ANS 2 - Systems like this always work better if the well pipe goes directly to the pressure tank. At the tank outlet you have two pipes, one to house, one to irrigation. A larger tank than normal is necessary too, at least a 100 gal tank, operating at 50-80 psi is desirable.
A sprinkler system is a device that waters your plants or grass
High water pressure from the street or well, but there's an exception: City water pressure (from the street) may need to have the pressure reduced to the home. Some homes have pressure regulators for this purpose, some do not. The same goes for well systems that use a pressure pump (an often a pressure tank); the outlet pressure is set so that the pressure to the home doesn't go too high or too low. An exception for homes with fire sprinkler systems. There is a check valve from the main water supply that feeds the fire sprinkler system. As temperatures drop at night, the water in the fire sprinkler pipes contracts slightly and additional water from the main water line goes into the fire sprinkler system. During the day, the water in the fire sprinkler pipes heats up and expands slightly, but has no where to go because of the check valve. This action can cause a very high pressure in the fire sprinkler pipes if there isn't also a pressure relief valve in the system. Numerous older homes do not have a pressure relief valve for the fire sprinkler system and risk having a pipe or joint burst. The bottom line: if you suspect that you have high water pressure in the home, consult a local plumber or building contractor for the appropriate solution.
Obviously, the branch-off for your sprinkler system has a bowwevel or some sort of virus like that.............so.......you should get that checked out.
Ask This Old House - 2002 Water Saving Toilet In-Ground Sprinkler System 7-21 was released on: USA: February 2009
My parents went through this when they moved into there house. It is an older house. They ended having a plummer replace some and clean out the pipes. There was alot of calcium and mineral build up inside the lines. If it is just this outside faucet maybe you could just replace this pipe with new one. The faucet itself could be clogged. Good luck.
Sounds like a bad/failed water pressure regulator.
LAWN SPRINKLERS HAVE A VERY LARGE PIPE(USUALLY A 1 INCH) WHILE THE REST OF THE HOME USUALLY HAS A SMALLER LINE. WHEN THE SPRINKLER VALVE IS OPENED, WATER FROM THE UPPER PART OF THE HOUSE CAN DRAIN INTO THE SPRINKLER SYSTEM LEAVING AIR POCKETS. WHEN YOU SHUT OFF THE SPRINKLER THIS AIR IS EJECTED FROM THE HOUSE FIXTURES. OTHER THAN THE SURPRISE, IT SHOULD POSE NO PROBLEM.
If it is a plumbing pipe, it probably will. The water line from the meter to the house is the owner responsibility. If it is part of a lawn sprinkler system, it may not be covered.
The force at the input of a sprinkler can be found from F = PA; where P is the pressure of the water at the spigot or source of the water to the sprinkler and A is the x-sectional area of the input hose to the sprinkler. EX: A typical house-hold water pressure is about P = 60 psi in the US. And a typical hose is a 1/2 inch diameter; so A = pi (D/2)^2 = pi (.5/2)^2 in^2 is the x-sectional area. Which means the force at the input would be F = PA = 60pi()(.5/2)^2 = 11.78097245 ~ 12 pounds of input force. ANS.
Low pressure causes:Low pressure supply from the mainIn a rural or well system a worn or failed pressure switch.In a rural or well system A leak in the casingIn a rural or well system a worn or failing pumpMineral build up inside pipesA partially closed main supply valve either curb stop or in house supply valvekinked or damaged pipe either under ground or inside.If there is a water softener or filter these can fail or become plugged.In Europe many houses have booster pumps to boost pressure and flow, these fail also.
This is not answerable question. Each municipal system will have a water pressure set by the municipality and every single house system set by the individual doing the maintenance.
Possibly a pressure reducing valve installed after piping for first faucet, which would cause situation describing.
