Sprinkler Head Not Popping Up? 6 Common Causes

When one or more sprinkler heads stay below the grass while a zone is running, the cause can be as simple as a damaged head or as broad as a pressure problem affecting the entire zone.

1. The sprinkler head is damaged

Dirt, internal wear, mower damage, or a cracked body can prevent a pop-up head from moving normally.

2. There is not enough pressure

If several heads fail to rise at once, look beyond the individual heads. A leak, partially closed valve, supply restriction, or valve problem can reduce pressure across the zone.

3. An underground line is leaking

A broken lateral pipe or fitting diverts water before it reaches the sprinklers. Wet soil, bubbling water, or an unusually green patch can help identify the problem area.

4. The nozzle or filter is clogged

Debris can restrict flow and distort the spray pattern. Cleaning or replacing the nozzle may solve an isolated problem.

5. The valve is not opening fully

A valve or solenoid issue can restrict flow to an otherwise healthy zone.

6. The zone has too much demand

Changes made over the years can leave too many or mismatched heads on a single zone. Proper diagnosis should separate a new pressure problem from a long-standing design limitation.
