I have a hardie sprinkler system that runs off the city water supply. There is very little pressure to no pressure out of the sprinkler heads. It seems to be routing to each station like it should, but there is pretty much no pressure to push the heads up. I'm not sure what the problem could be.

If you take the sprinkler off and just run the spigot without the sprinkler system is it still little pressure?

I can't really remove the system from the spigot because it is too difficult to get to, but on the spigot there are what appear to be bleeder valves and the seem to have excellent pressure.

If the water to the spigot is fine then the system may have mineral and/or micro organism deposit build up

How many sprinkler heads do you have? What size pipe from meter to house.
