What Customers Say About Us

Hey Jennie, just wanted to let you know. 3600 heads over 23 buildings in an institutional prison setting in 2 months by 4 guys (40 actual working days). Your Dropmaster is amazing. Without the Dropmaster, it would have taken double the time.

Ross Arnold

Co-Owner, Golden Ears Fire Ltd

Great investment! If you take care of that thing, it'll take care of you.

J.R. Bradfield

HYDRA-TAP - Founder/Inventor

One of the best tools money can buy. Truly a blessing for service fitters.

Thomas Hassler

Fire Sprinkler Technician/Inspector; Backflow Test & Repair

We have one, it’s awesome! We have had our Drop Master for 8 years. We have used it for hundreds of sprinklers in hotels, large mansions and everywhere else where there is going to be an expensive problem with one drop dripping from the sprinkler system ruining a carpet or furniture. We use the hitch carrier on our pipe fitter truck and that works great too.

Pat Dillon, CET

Manager - Fire Chief Equipment

I received my Dropmaster this week. Clean pipe work with no mess or drain bucket.

It's been a great product for Escape Fire, we highly recommend the use of the Dropmaster if you have any plans on changing sprinklers or working in office areas where you are trying to eliminate the chance of water damage.

How does the Dropmaster work?

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.

Is it easy to maintain?

Yes, the system requires minimal daily maintenance that takes only a few minutes.
Daily Maintenance:

  • Check the strainer. Remove basket to clean. Remove any debris.
  • Drain barrel to protect from excessive corrosion build up and freezing.
  • Check oil reservoir. Fill as needed.
  • Drain excess oil from the catch basin in the muffler.

Is it reliable?

Every Dropmaster™ comes with a one-year warranty. Made in the USA, the Dropmaster™ is durable, built to last, and proven in the field. The Dropmaster™ was designed and built for 24/7 operation, and all components are rated for continuous duty.

How much labor time will it save?

The Dropmaster™ eliminates residual water in a sprinkler system so that sprinklers can be replaced without using buckets and tarps. By reducing both set-up and clean-up time, many contractors report labor savings of 40% to 60%, and some even claim 80%.

Are replacement parts available?

Yes, contact us for more information. Replacement parts for older units may have limited availability.

Can I get a demonstration?

There is also a series of videos under our “Products” tab that are highly informative. If more is needed, contact us.

Why should i get a Hitch-Mounted Carrier?

The hitch mounted carrier allows you to transport the unit in its required upright position. The hitch provides easy curbside loading and unloading. By utilizing the hitch-mounted carrier, you can avoid occupying valuable space inside your service van or truck.

Can i use it anywhere, on any system?

Yes! The Dropmaster™ is versatile and can be utilized for any type of system, regardless of its location, as long as there is access to a functional electrical outlet or power from an electrical generator.

Will the Dropmaster harm the system?

The Dropmaster™ is designed to maintain and not exceed 10” Hg of vacuum. Manufacturers of grooved couplings recommend not exceeding 15” Hg vacuum on a sprinkler line. The Dropmaster™ is the only tool that will hold the regulated margin of safety.

Can we add extra hoses?

Yes! Extra lengths of vacuum hose may be added and can be ordered here. Contact us for additional hose if needed.

Can I use an extension cord with it?

The Dropmaster™ is powered by a ¾ horsepower 15amp motor and supplied with a 20,’ 12-gauge power cord. Using an extension cord is not recommended but maybe allowable under certain circumstances.
