Troubleshooting Low Sprinkler Pressure and Well Performance

Homeowners often face declining sprinkler performance, and the root cause isn't always obvious. In this case, a system installed just 20 months ago began showing weak pressure—one head popped up intermittently, and another had been buried. The original contractor blamed the well, claiming it wasn't producing enough power and recommended drilling a new one. The well had existed for 10 years but wasn't used for irrigation until recently. The homeowner wondered whether drought conditions in southeastern Virginia were to blame or if a new well was truly necessary.

Expert advice suggests getting an independent well specialist to evaluate the situation. While the water table may be low regionally, a well that functioned 20 months prior shouldn't suddenly go dry without a mechanical issue. The sprinkler installer may have a conflict of interest, so a second opinion from a dedicated well professional is crucial. Possible causes include a failing pump, clogged screen, broken casing, or electrical problems—not necessarily a dry aquifer. Before investing thousands in a new well, verify the actual condition of the existing one.
