How much does the 2 ½” Hose Monster weigh? It must be heavy to keep from whipping around.

The 2 ½” Hose Monster weighs 27 pounds, and the 4″ and 4 ½” Hose Monsters each weigh 45 pounds. However, their weight is not what keeps them from whipping around. The thrust is cancelled by flowing water in two opposing directions. The Hose Monsters weigh as much as they do because of the durable material they are built with.

How much water can I flow through the Hose Monster without damaging it?

A lot, probably more water than your system can provide! Water never has and never will damage the Hose Monster.

Can I take flow readings by inserting a hand-held pitot in the vent hole on top of the Hose Monster®?

We do not recommend this method. The vent hole was not designed for flow readings, and the accuracy of that method has not been verified.

What are the maximum and minimum flow-rates I can read from the Hose Monster?

Our equipment can test water flow-rates as low as 48 GPM (1″ Pitotless Nozzle™) up to 2943 GPM (4″ Hose Monster). Call us or refer to flow charts to determine which equipment to select. The flow charts provided with the Hose Monsters and Pitotless Nozzles indicate the flow-rates for which we have supporting laboratory test data.

Why do I need an extra pitot when I get the 2 ½” Hose Monster?

Sometimes a piece of debris hits the Hose Monster’s built-in pitot and damages it in the middle of a flow test or pump test. When this happens, you can change out the damaged pitot with the spare that you keep on hand. All you need is the Pitot Change-out Kit (PCK) — or a ⅛” hex wrench and magnet — and a few minutes. And be sure to save the old pitot! It can be rebuilt at the factory for far less than the cost of a new pitot. Contact us for a return authorization.

Where is the pitot in the 4″ or 4 ½” Hose Monster?

These Hose Monsters use an FM-Approved orifice plate, not a pitot. It is ideal for flushing operations because it is both accurate and durable. We have never had a complaint of the orifice plate being damaged from flushing debris.

Can I thread the Hose Monster directly to the hydrant?

It is physically possible, but it shouldn’t be done. The primary benefit of the Hose Monster is realized by using a hose. It gets the flowing water away from the hydrant and into the street gutter, plus it neutralizes the turbulence when flowing close to the hydrant nozzle. It’s common to see a gauge needle bounce ±10 or more psi when measuring flow close to the hydrant.
