Toilet Trends

Customers are demanding more eco-friendly options. Whether they’re at the mall, at the grocery store, or looking to update their bathroom, they want products that have low environmental impact. Homeowners are trending towards low-flow toilets that maximize flushing power and reduce water consumption.

Low-flow models rely on pressure and gravity to get the most bang per flush without relying on excessive water. Some models show that switching to a low-flow commode can save up to 4,000 gallons of water annually, because they use just over a gallon per flush.

While the models can save customers money and help the environment, they can present certain challenges to plumbers.

“The margin for error for providing adequate evacuation and drainage has now shrunk considerably and can result in less than optimal performance in challenging situations, such as when there is marginal water pressure or old and poorly pitched drain lines. The industry needs to take a hard look at building and plumbing standards and determine if they need to be updated to account for the changes in water usage,” said Mark Lawinger in an interview with Supply House Times.

Some low-flow customers report having to flush multiple times to clear away heavier loads. Other homeowners with older houses don’t have compatible plumbing lines to connect a more efficient toilet. reports that when there are too many low-flow toilets in one area, a stinky problem can arise: if there’s not enough water to push sewage through, waste can back up. This same problem can happen on a smaller scale: inside the house. Non-flushable waste is more likely to back up when it’s being handled by a low-flow model.

As customers demand more low-flow toilets, manufacturers will have to continue working on a solution that strikes the perfect balance between eco-friendliness and power to avoid these issues.
