Commercial Plumbing: A Blocked Drain and a Failed Flush Sensor

One NCRC call covered two faults. See the real photos, drain work and toilet sensor repair, with a clear record of what the tech checked.

By NCRC · Service dates October 15, 2026

A urinal would not drain. A toilet in another restroom would not flush well. One NCRC service request covered both problems. On October 15, 2026, a Masterline tech handled the visit and wrote down the work on each fixture.

The two fixtures needed different work. One needed drain service. The other needed flush-valve and sensor parts.

Clear the urinal drain

The tech’s note says he used a drain snake to clear the urinal line. He then added a urinal treatment to help clean the pipe. The note does not identify the material that blocked it.

This was the drain part of the call. It did not explain the fault at the toilet in the other restroom.

Restore the toilet flush

The toilet needed a new diaphragm, a new motion sensor and batteries. A diaphragm is a part inside the flush valve that helps control water flow. The sensor starts the flush.

The tech recorded replacing the parts and flushing the toilet to check it. His note says it was working again. He also recorded that the manager checked and signed off before he left.

What the result does and does not show

The note records clearing the urinal and a working flush at the toilet. It does not give a flush count, a drain-camera view or a later follow-up check. We do not add those claims.

A related two-urinal case covers a different visit with its own water checks. Each case keeps its own facts and photos.

List each fixture in the request

  • Name each fixture and its problem.
  • Say whether it will not drain, will not flush, or keeps running.
  • Ask what was done to each one.
  • Ask what was checked and what still needs work.

For commercial plumbing service coordination, send NCRC the location, scope and timing. We confirm each request by place and trade. A single job does not show that a crew is available in every city.
