Commercial Toilet and Urinal Repair in Phoenix

Running and weak flush are different problems with different causes. A toilet that keeps running has a mechanism that does not seal. In a tank-type toilet that is a flapper or fill valve, and in a flushometer toilet it is the valve, which has its own page at flushometer valve repair. A weak flush is a supply or drain problem: low pressure at a flushometer, a partial clog in the bowl's jet or the drain, or a vent that is not letting air in. Check how many fixtures behave the same way. One bad fixture is a fixture problem. Several on the same branch point to the drain or the supply. Our guides on fixing a running toilet and toilets that will not flush fully cover the home-size versions, and commercial restroom stoppages belong to drain cleaning.

A bowl that leaks at the floor has lost its seal at the flange, or its bolts have loosened. The code asks for corrosion-resistant flange screws or bolts, a plastic flange at least 0.25 inch thick, and sealed joints where fixtures meet the floor. A rocking toilet is a warning, because movement breaks the seal and lets sewage seep under the fixture. See a toilet leaking at the base and fixing a broken toilet flange. In a slab building the leak runs under the finished floor, so a smell with no visible water is a hint; sewer smell from a cracked drain under a slab covers the other explanation.

When the bowl moves, the carrier or its anchors have shifted. A wall-hung toilet sits on a concealed metal carrier attached to structure, not on the wall finish. If the bowl sags or rocks, the mounting bolts may be loose, the wall may have been damaged, or the carrier is out of position. The first fix is to tighten the bolts and check the seal at the connector. If the carrier is bent or anchored to drywall alone, the wall has to be opened. Public restrooms use elongated bowls and open-front hinged seats, so a seat swap is a standard maintenance item; ADA seat height is 17 to 19 inches, which is another reason not to substitute a household seat.

Urinals fail in three ways. A flush valve problem looks like the toilet version. A drain problem is usually scale, because urine crystallizes in the trap and arm, and our page on uric scale clogs in a urinal line explains it. And a waterless urinal that smells needs a new cartridge or trap liquid, covered in waterless urinals and sewer odor. Phoenix sets urinals at 0.5 gallon per flush in covered work, so a replacement fixture and valve are sold and set to that volume, and ADA rim height is 17 inches maximum. Check with the building department on whether a replacement is covered by the new limit.

It changes what you buy, not how a repair is done. A repair kit or part restores the fixture's current flush. A replacement toilet or urinal installed under a permit is covered by Phoenix's lower limits, unless the building type is exempt. Care facilities, buildings over six stories and some others keep the 1.6 and 1.0 gallon limits for health-related reasons stated in the amendment. Ask for the rated flush volume on any fixture you buy, and ask the plumber to confirm that the valve and fixture match.

If a toilet is cracked, the porcelain is chipped at the rim or a base has been reset more than once, replace it. If the restroom is being altered anyway, consider the full restroom remodel. If the drain, not the fixture, is at fault, a new toilet will not cure it; see commercial drain cleaning. And a toilet that overflows needs the stoppage cleared first and the fixture inspected second.
