Chicago plumbers explain low toilet bowl water levels

An improperly working toilet can become a major headache for any homeowner.

David Lamb of Power Plumbing & Sewer Contractor Inc. and Jerry Schuster, owner of Diversey Plumbing and Sewer, both highly rated companies in Chicago, explain why some toilet bowls fail to refill with an adequate amount of water after a flush.

“The problem is caused by the fill valve,” says Lamb. “It fills the tank for the next flush.”

The fill valve is the long, cylindrical component in the toilet tank that replenishes the bowl with fresh water after a flush. It determines how much water to use based on the position of the fill float which rises in conjunction with the tank’s water level.

Both Schuster and Lamb agree that the leading cause of a faulty fill valve is age. It can deteriorate due to continuous use and close proximity to water. Lamb says poor water pressure or sediment buildup can also cause the fill valve to malfunction.

Low water level doesn‘t necessarily mean the toilet is broken; it just means that it’s not working to the best of its ability and could lead to further problems. Schuster says a low level can easily result in a clogged toilet since there is less water moving through the pipes.

Fortunately, repairing a broken fill valve is simple. Replacement parts for a typical toilet cost around $20 and  the job can be completed in less than an hour.

Lamb recommends regular toilet maintenance like scrubbing the parts with a brush to prevent deterioration. But,  “Do not use drop-in tank cleaner tablets - they can block up the inside parts and may void the warranty," he warns.
