The Dropmaster DM25 is a siphoning tool designed to make sprinkler removal cleaner, faster, and more efficient for testing and replacement. By creating a powerful vacuum after your sprinkler system has been drained, the DM25 removes trapped water from the system, eliminating the need for buckets, tarps, and messy clean-up.
Its integrated pump collects and discharges water exactly where you want it, helping reduce downtime and keep the work area dry and organised.

Attach the Dropmaster suction hose to the sprinkler riser after draining the system. The unit plugs into any standard outlet or generator.
The unit maintains a safe, regulated 10" Hg vacuum — keeping water back in the pipe while the system is open for service.
Swap the sprinkler head clean and dry — no buckets, no tarps, no cleanup. Save 40–60% on labor per job.

The Dropmaster™ is designed to be compatible with any part of the sprinkler system. Upon connection and activation, it consistently maintains a vacuum of 10” Hg whenever the system is compromised, such as when a sprinkler is removed, causing a siphoning effect. This innovative feature enables the installer to replace the sprinkler without the need for a bucket, preventing any messy spills. Additionally, the Dropmaster’s flexible discharge hose conveniently connects to any drain, ensuring a clean and odor-free work area with ease.
