Cold weather is on the way. Be prepared by protecting your backflow!

SWIS now offers guaranteed protection.
10% off in the month of January!

Option 1: Have our licensed technicians drain your backflow completely including pipes, bleed valves and shut off valves. You cannot run your system when you drain the water until the spring. Sprinkler system backflow must have an isolation valve to qualify for this guarantee.

If your backflow is damaged or not installed properly, we may be unable to drain.
Want to keep your system running and not shut your system down. We have an option.

Option 2: Install a Wilkins freeze relief valve and a freeze protection bag. You must have a Wilkins backflow to install properly. This option will allow you to run your sprinkler system if needed all winter until spring. Freeze relief valve and protection bag must be left on during freeze event.
