Spring is the perfect time to inspect your drip irrigation system and sprinklers for any potential problems, as well as resetting your irrigation timer from the less frequent watering winter watering schedule. Even a yard that is primarily native desert plants will need water throughout the spring and summer. Most plants grow most actively in warmer weather, so you are likely starting to see new growth. Couple the growth with rising evaporation rates as temperatures rise, and more water is required. Some local municipalities offer free workshops on how to program your irrigation timer and maximize landscape watering efficiency.
Check your timer to make sure it is working properly when you reset it. Run through each of the valves’ settings and make sure each valve comes on when it should. When valves start to deteriorate you may have a situation where a valve will remain running. Once you determine which valve is running, it will most likely have to be replaced. You might also notice that there is a puddle or consistent wet spot around a sprinkler head. This is again the sign of a worn out valve that probably needs to be replaced due to leaking.
Check to see that sprinkler heads are popping up properly and to an appropriate height. Most can be adjusted per manufacturer’s instructions to spray in the right direction and the right distance. Also check your drip emitters on various plants. These emitters can clog with mineral deposits, or sustain damage from sun and general wear and tear. They are inexpensive to replace after snipping off the old emitter.
It’s not uncommon to develop splits in old, brittle irrigation lines over time. You may see water bubbling up in a certain spot. Turn your system off while you carefully dig to see where the leak is and how extensive the damage is. Be careful not to further damage the line when you are digging! Most leaks are easy to repair with inexpensive materials from your local hardware store.
