| If the sprinkler is hooked to a hose which is hooked to an outdoor faucet, the problem could well be that the faucet is not/cannot open sufficiently wide to allow the water to continually fill the hose. A sign of this is when you turn on the faucet, wait a minute, and then turn on the sprinkler which will run properly for a bit before evidencing a gradually diminishing water-flow -- the sprinkler literally is not receiving enough water to run full-force. A blockage in the water pipe leading to the faucet will have the same effect. Unless you are very handy with plumbing, call a plumber to repair. A second possibility is a kink, hole, or leaky connector in the hose; any of which would have the effect of diminishing the water supply to the sprinkler. Check the hose to remove kinks; and all connections to be sure they are properly tight and non-leaky. A third possibility is simply that the sprinkler does not run as forcefully as you expect it to, due either to having a blockage within the unit, or as a matter of design (changeable only by changing the sprinkler itself). A fourth thought is that the well system cannot keep it's tank refilled as fast as the sprinkler is pulling the water. I'd consider this unlikely, but as a last resort, check to see if you can run an in-house sink faucet full force continually for 20 minutes without diminished pressure. (Conserve the water by attaching a hose to the faucet or otherwise saving the water for re-use.) |
