WELCOME TO WATERWAY LONG ISLAND
Some departments still choose to perform their own annual hose testing. We would like you to review this page before you make your decision.
As you are aware, annual hose testing is a requirement under NFPA 1962. We realize cost is always a concern for your district and taxpayers, but if you consider all the advantages of Waterway you'll realize it is quite a good value for the cost. You only need to provide the location, hose, and a water supply. We do everything else. In the case of comparing in-house testing vs. Waterway, consider:
- Entire hose testing is usually completed in only 1 or 2 days.
- NFPA and ISO compliant reports, and an inventory software CD on your desk within (1) week
- We use only our manpower and equipment; no additional FD equipment is required
- No use of volunteers to meet annual hose test requirement, use training time for training
- No potential for injuries to Fire Department or District personnel, or damage to your equipment
- Hose test reports are always available online 24/7
You know your crew hates doing it!
We follow ISO-9001 procedures
Your firefighters are not trained for hose testing, we are. It is performed properly
Reduce liability using third party tester
Our equipment is calibrated as per NFPA requirement
If it is not documented properly, it was not done. We provide the proper documentation
Think this is all sales hype???
Here is a LDH Discharge that broke off during hose testing.
The above LDH discharge blew apart during hose testing. The valve pushed the pomp panel out enough to break the ladder brackets. It caused $48,000 damage and apparatus was out of service for 4 months. Luckily no one was injured.
This picture shows damage caused by "recirculation cavitation". Note that the leading edge of the stripping edge is worn back and the major pitting just to the right. (All caused by recirculation cavitation/erosion).
What causes recitrculation cavitation?
"Well lets see, Hose testing certainly can!!!"
Scenario- A pump operating at high (head) pressure with little or no water flowing from a discharge (could be hose testing) - As the impeller speed increases to raise the discharge pressure, the pressure at the eye of the pump decreases reducing the point at which the water will vaporize. Because the flow rate out of the pump (in this case) is close to zero, the water at the impeller has to "go around" again, increasing its temperature. As the temperature of the water increases, its vaporization point decreases and vapor bubbles form in the low pressure side of the pump (the eye). When the heated water and vapor bubbles go from the low pressure point at the eye to the higher pressure point at the discharge of the pump (The "stripping edge"), cavitation occurs there, damaging the stripping edge.
Even if the tank fill / recirculation valve is opened to allow water to flow through the pump, it doesn't take very long for the water in a 500 gallon tank to heat up. In fact one major pump manufacturer found that 500 gallons could be heated to 140 degrees in a very short period of time with the tank fill valve open. This increase in water temperature just makes it easier for cavitation to occur. (reprinted with permission from EVT TechTalk forum 3/28/09).
Don't believe mechanics? How about reports from manufacturer's of pumps:
"Hale does not recommend using Fire Pumps for testing hoses".
"While our pumps "can" hose test, it doesn't mean they should. Darley recommends against using centrifugal pumps for hose testing."
We can show you the engineering notes from major pump manufacturers who do not recommend using their product for hose testing, just ask for a copy There are plenty of documented cases of pump damage on Long Island alone attributed to hose testing.
And thats only the apparatus,How about the safety of your personnel?
