It is common for potable water supplies to be dual purposed to also supply fire protection system water. When this potable water system is being cleaned, there's a good chance that cleaning the hydrant legs will be the efficient, cost effective, choice.
Flow measurements at the hydrants taken before and after cleaning the rest of the system will often reflect significant gains in flow rate, sometimes as much as 300 or 400%.
Other times, if the pipes feeding the hydrants are not cleaned, they may continue showing a reduced flow capacity. For this reason, my client, Professional Piping Services, Inc., recommends cleaning the hydrant leg during the overall system cleaning.
Including Hydrant Leg and Hydrant maintenance in the service allows old, sometimes literally antique hydrants to be identified and replaced. This can often be done with one cut and one coupling! Getting rid of these old plugs means you'll spend less time trying to fit outdated bolts, gaskets, valves and what-not that are not readily available. You might even take the opportunity to move a hydrant if you've been looking for a chance!
Including Hydrant Leg Pipe Cleaning in the project allows you to maximize the return for the investment in time, efforts and funding.
