Sprinkler systems are very convenient and the newer timers have many programing features and options. What about the sprinklers in relation to your structures?
If your house or building structures are made of wood or wood products and the sprinklers are not correctly adjusted, the siding can become saturated and lead to decay or even produce mold growth. After all the main ingredient needed for mold to grow is water. As part of the INTERNachi Standards of Practice I examine the siding or exterior wall coverings for water damage or intrusion in all my inspections.
Even with masonry or brick exterior walls with a good paint or sealer, over time miss-adjusted sprinklers can create an avenue for water intrusion into your home or building, which if nothing else can lead to a maintenance nightmare.
My recommendation is to check the coverage of your sprinkler heads once a month and adjust as necessary to prevent a large repair bill. A little maintenance now can save you $$.
The photos below show the results of prolonged exposure to miss-adjusted sprinkler heads. This siding will have to be replaced and repainted (it sure is easier to adjust heads).
Winter is fast approaching the Front Range of Colorado, make sure you have your system drained by a professional or if you have an air compressor and the knowledge you can do it your self (MAKE SURE YOU KNOW HOW).
