When The Maintenance Shop performs your sprinkler blowout we on only the minimum amount of air pressure required by your particular system. We start out at a low pressure and then increase as necessary to make sure all the water is out of the lines. Pipes and fitting connections can weaken with age so care has to ber taken to not cause a break in the line. If sprinkler heads are old or clogged, or have been damaged in some way by lawn mowers, weed whackers, etc., the chance of "blowing" a sprinkler head increases. Keep the filters in your sprinkler heads clean; if water can't get through properly it also increases the chance of a "geyser" when air is put through the lines.
The Maintenance Shop also winterizes homes as well. If your home is going to remain vacant over the winter months call or email us! We will drain the water heater, remove water from the toilet tanks and bowls, and blowout the water in the lines that run through your home. If you are putting your RV or camper away for the winter we can remove the water from thatm as well. Email us for home winterization and RV rates.
This is the "Cyclone", our largest air compressor at 250 cfm.
Below is an example of the damage caused by water freezing in PVC pipe. The particular section was 10 feet long, but we also replaced a 3-foot section in the parking strip, and another broken pipe under the driveway that was almost 20 feet long. When PVC pipe freezes it usually ends up with a spiral crack that runs the entire length of the pipe from coupling to coupling. By the time we were finished with all the sprinkler system repairs at this home the bill was near $400.00. All because the system was not blown out the previous fall.
