If you\u2019ve ever worked in any sector related to water treatment \u2013 whether that\u2019s municipal supply, industrial manufacturing, or commercial building operations \u2013 chances are you\u2019ve heard of the By Opening Method. As someone who\u2019s spent the last 12 years selling, supporting, and refining this technology for my team, I\u2019ve seen first-hand how it has revolutionized parts of the industry, cutting down on maintenance costs, reducing downtime, and making system flushes more effective than many older, manual approaches. By Opening Method<\/a><\/p>\n

<\/p>\n

But here\u2019s the thing: I don\u2019t sell a technology that\u2019s perfect. No treatment method is, and pretending that there are no limitations would do a disservice to my customers, who rely on us to solve real problems without overlooking potential roadblocks. Over the years, I\u2019ve talked to hundreds of clients \u2013 plant managers, maintenance supervisors, and process engineers \u2013 and their feedback has helped me see the gaps in the By Opening Method, even as we continue to improve our own products to address them.<\/p>\n

Let\u2019s start with the basics, for anyone who might be new to this. The By Opening Method works by systematically opening and closing valves in a water (or other fluid) system to create controlled surges, or localized pressure changes, that dislodge scale, sediment, biofilm, and other contaminants from pipe walls. The idea is that instead of using harsh chemicals that can damage pipes or require complex neutralization, this mechanical approach moves debris naturally, so it can be flushed out without adding extra substances to the system. It\u2019s become a go-to for many mid-sized systems where chemical treatments are too expensive or leave residue that affects downstream processes.<\/p>\n

But first, one of the biggest limitations I see has to do with pipe size and layout. The By Opening Method relies on the fact that pressure surges travel predictably through pipes. But if you\u2019re working with pipes smaller than, say, 2 inches or larger than 24 inches, the method\u2019s effectiveness drops off sharply. For small-diameter pipes, the surges generated are often too weak to dislodge stubborn scale that\u2019s built up over years, especially in areas where pipes have tight bends or connections. For large-diameter pipes, on the other hand, the surge needs to be significantly more powerful to cover the full cross-section of the pipe \u2013 and many standard By Opening Method systems aren\u2019t calibrated to deliver that. I\u2019ve had a client in the food and beverage industry with a 30-inch main process pipe; they tried our standard system and were frustrated when half the pipe still had biofilm after treatment. It took us six months to re-engineer our valve sequencing to adjust for the larger pipe, and now that client is a repeat buyer, but that initial gap is a real barrier for anyone working with extreme pipe sizes.<\/p>\n

Then there\u2019s the issue of pipe material. Most By Opening Method systems work well with standard carbon steel, copper, and even PVC for non-critical applications. But when pipes are made of more fragile materials \u2013 like galvanized steel that\u2019s corroded, thin-walled stainless steel, or older cast iron that\u2019s been weakened by decades of use \u2013 the pressure surges can do more harm than good. I learned this the hard way with a municipal water district client last year. They had a network of 80-year-old cast iron pipes in a residential neighborhood, and they wanted to use the By Opening Method to reduce the need for chemical flushes. When our tech team ran a trial, the surge pressure caused a small crack in one of the oldest pipes, leading to a 24-hour outage for 12 homes. That incident didn\u2019t just cost the client money; it made me realize that many providers of this technology don\u2019t do pre-treatment assessments of pipe material and condition. A lot of sales pitches skip over the fact that you can\u2019t use the method on any pipe without first auditing its structural integrity, and that\u2019s a limitation that isn\u2019t talked about enough.<\/p>\n

Another common limitation is the method\u2019s reliance on system flow rates. The By Opening Method works best when the system has a minimum flow rate that can carry the dislodged debris out of the pipes quickly. If the system is part-time, or if it\u2019s a closed-loop system that doesn\u2019t have a way to direct flushed debris to a collection point, the contaminants can settle back into the pipe walls. I had a client in the pharmaceutical industry with a closed-loop cooling system; they tried the By Opening Method and found that after treatment, sediment settled in dead legs of the pipe, which then grew new biofilm within two weeks. The problem was that their system didn\u2019t have a dedicated flush path, so the method\u2019s surges stirred up debris that had nowhere to go. The fix wasn\u2019t in adjusting the system\u2019s settings, but in adding a temporary flush line \u2013 a solution that not every customer is willing to invest in, especially for small, temporary maintenance projects.<\/p>\n

I also can\u2019t ignore the variability in system conditions. Every water system is unique, with different levels of hardness, sediment composition, biofilm thickness, and even pipe corrosion. The By Opening Method works best when you have a baseline understanding of these conditions, but many small businesses don\u2019t have the resources to run pre-treatment water tests. I\u2019ve had a small manufacturing plant with hard water that tried the method, and their limescale was so thick that the standard surge pressure could only dislodge the outer layer, leaving a hard core inside the pipe. They ended up needing a chemical pre-treatment to soften the limescale before using the By Opening Method, which added time and cost to their project. If a customer doesn\u2019t know they need that pre-step, they\u2019ll be disappointed with the results, and that\u2019s a limitation of the technology that often gets buried in marketing materials.<\/p>\n

Now, as someone who sells this technology, I don\u2019t want to end this sounding like By Opening Method isn\u2019t worth using. Because it is \u2013 for the right applications, when paired with proper assessment and support. The key is understanding these limitations and building solutions around them, rather than ignoring them. Over the past few years, my team has spent a lot of time developing custom calibration tools: software that can map pipe layout, size, and material to adjust surge pressure and valve sequencing, so we can adapt the method for small and large pipes, fragile materials, and closed-loop systems. We also now offer free pre-treatment assessments for all our clients, including water testing and pipe condition audits, to make sure the method is appropriate for their specific system before we even ship a unit.<\/p>\n

One of the most rewarding parts of this job is seeing clients who once wrote off the By Opening Method because of a bad early experience come back to us with successful projects. A few months ago, that same municipal water district that had the cast iron pipe incident came back to us. They\u2019d worked with a structural engineer to assess their oldest pipes, and they used our new low-surge valve sequence for those lines, avoiding further damage, while using our high-pressure calibrated system for newer steel pipes. They reported a 40% reduction in chemical use and a 30% drop in pipe repairs within six months \u2013 results that wouldn\u2019t have been possible if we\u2019d ignored the limitations we talked about.<\/p>\n

For anyone considering the By Opening Method, my advice is simple: don\u2019t just go with the cheapest or most advertised system. Ask about their calibration tools, their pre-assessment process, and their experience working with your specific pipe size, material, and system layout. A lot of the \u201climitations\u201d aren\u2019t flaws in the technology itself, but flaws in how it\u2019s applied, and choosing a supplier who\u2019s honest about those gaps and has solutions to address them is what makes the difference between a successful project and a frustrating one.<\/p>\n

<\/p>\n

If you\u2019re looking to reduce your maintenance costs, cut down on chemical use, or improve the efficiency of your fluid system, I\u2019d be happy to walk you through how the By Opening Method could work for your operation, and what steps we take to avoid the common pitfalls I\u2019ve talked about over the years. We can talk through your specific pipe layout, system type, and goals, so you know exactly what to expect \u2013 no sales pitch, no fine print, just honest information to help you make the right decision for your team.<\/p>\n
