A mechanical, oscillating lawn sprinkler has a lot of moving parts. If your lawn sprinkler has started to malfunction, it does not necessarily need to be tossed out. Problems that can occur with your lawn sprinkler might have a simple solution.
What might go wrong with your oscillating, mechanical lawn sprinkler and how you can discover the problem and fix it
Oscillating, mechanical lawn sprinklers with low water pressure or sputtering might be fixed using the ideas listed here:
Check the water hose. There may be a kink in the hose that restricts water flow.
If the hose is gushing water at the sprinkler connection, try replacing the hose gasket.
High water pressure may damage the internal sprinkler gears, causing them to rotate counter to their design. The oscillating bar will move either erratically or not at all, which causes the gears to go out of alignment. Try turning your faucet counterclockwise to lower the water pressure reaching your sprinkler.
If these solutions do not work, you may need to replace some sprinkler parts.
A few ways to take care of your lawn sprinkler parts
Detach your sprinkler from the hose.
Examine your sprinkler’s aluminum tubes. If the tubes get stepped on, the aluminum skids get bent, causing the middle part to pinch and not oscillate.
Cleaning your sprinkler head and the water hose head may solve your sprinkler issues. Remove all grass, dirt and debris that has collected in the water inlet before reattaching the hose.
Occasionally, you may need to clean or soak your sprinkler head using white vinegar. This can help break down scale and mineral deposits that build up in spray holes.
Metal and plastic gears become clogged and result in sluggish movement. Once you have cleaned the areas, try lubricating them for better gear meshing.
