affordable nozzle designed to prevent blown toilets, according to Story, who was instrumental in its development.
“I designed a new nozzle specifically to prevent blown toilets. The nozzle, called the Toilet Tamer, substantially improves upon a previous, more costly design [the Equalizer],” says Story, who has decades of experience training operators to effectively clean sewers, and intimately understands problems in the field.
According to Story, with the precisely engineered water jet angles incorporated into the nozzle, the Toilet Tamer is designed to dramatically reduce the amount of airflow being pulled through the pipe.
“Virtually eliminating the amount of pressurised air present as the operator passes by a home’s service line prevents any sewer material from being blown up and out of residential toilets. So, no more ‘blown toilets,’” says Story.
Unlike the prior design, which can be challenging to navigate through pipes, the new nozzle is tapered like a football on both ends. The streamlined design eliminates “hang-ups” and ensures smooth passage through even misaligned or separated pipes.
The innovative nozzle is Tier 3 with exceptional water efficiency up to 90%, which translates into more sewer line cleaned per day with fewer operator trips to refill the sewer truck's water tank.
The most significant advances, however, are design and fabrication changes that dramatically lower the cost.
“The new Toilet Tamer nozzle costs about one-third of our previous model [that it’s based on], but is actually more effective in the field. We could charge more, but our goal is to put it in the hands of operators nationwide to solve the problem of blown toilets,” says Story.
The new nozzle has already been successfully field-tested, according to Story. A city north of Los Angeles, California, initially tried it for a few weeks.
According to Story, when the city’s operators tested the nozzle, they set it up in a 10-inch pipe above ground with a 6-inch lateral branching off. When they placed their hand over the 6-inch pipe,
they could not feel any significant vacuum, nothing like what they would normally expect. This was the first indication that the design was working as intended.
The city’s operators then moved about 300 feet up the line, just before it entered a manhole. At that point, a small amount of water was pooled at the edge of the pipe, and surprisingly, the nozzle did not even pull that water all the way in. That is when they realised just how effective it was—it appeared as if there was no air movement at all.
Impressed with the results, the city has ordered four more, equipping their sewer trucks and stocking their warehouse to ensure that the new nozzle is readily available for operators when needed.
Story is conducting additional testing on the new nozzle to document how air moves around it in the field.
“We’re applying science to solve one of the most aggravating problems that operators and municipalities have faced for many decades. The goal is to make the nozzle not only effective at eliminating blown toilets, but also very economical so that it’s available to operators and fleets whenever and wherever needed,” concludes Story.
As a national trainer of best-practice techniques, Spartanburg, SC- based KEG Technologies is a member of NASSCO, the National Association of Sewer Service Companies, and its Tier 3 High Efficiency nozzles, such as the Torpedo, Royal and OMG, provide up to 98% efficiency.
