Classroom Sink Hookups for a Tulsa Learning Center

A church-run learning center in downtown Tulsa needed the sinks hooked up in two back-to-back classrooms, an adult sink and a children's sink in each room.

In both rooms the shut-off valves for one side sat in the next cabinet over, so the supply lines would not reach without extensions. The drains tie into galvanized pipe coming out of the wall. In one room the toilet was backing up because it was caked with drywall debris, and the siphon jet was packed with it too.

We connected each faucet to the quarter-turn shut-off valves, adding supply line extensions to reach the far cabinet. We tied each sink into the galvanized drain and installed a new P-trap, then turned the water on and tested. We ran our toilet auger through the clogged toilet several times to free the blockage and cleaned the drywall out of the siphon jet. Where we saw a dripping faucet and a children's faucet with low pressure, we let the staff know so their maintenance person could follow up.

This project involved adult and children's sinks in two back-to-back rooms: the Foundations room and the Flex room. The work description lists two sinks in each room, for four sinks altogether. Trystan and Josh were assigned to the visit. Connecting the plumbing did not mean every existing faucet was in good condition, and the completion notes carefully distinguish the results at each fixture.

At the adult sink in the Foundations room, the faucet was connected to the quarter-turn shutoff valves. Supply-line extensions were necessary to reach the hot-side connection in the next cabinet. The crew tied into the galvanized drain coming out of the wall and installed a new P-trap. When the water was turned on, the drain worked properly, but the existing American Standard faucet dripped. The on-site contact asked for that faucet to be shut off and said the church or maintenance person would be notified.

The children's sink in the Foundations room also needed supply-line extensions to reach its quarter-turn shutoffs. A new P-trap connected to the galvanized drain at the wall. The existing faucet had very low pressure and leaked around the faucet when tested. The teacher said that concern would be passed to the church or maintenance person. The job description specifically says this sink's drain could not be tested. We are not changing that unresolved result into a claim that all four sinks passed.

There was another problem in the Foundations room: the toilet was heavily obstructed with sheetrock debris and backed up. The plumber ran a toilet auger through it several times to free the blockage. The siphon jet was also filled with sheetrock material and was cleaned out. The completion description says the toilet worked properly after that cleaning.

In the Flex room, the adult faucet needed an extension to reach the cold-side shutoff in the next cabinet. The crew connected its supply, tied into the galvanized drain and installed a new P-trap. That sink was tested and worked properly without issues. The children's sink in the same room was connected with supply-line extensions and a new P-trap, then tested successfully as well.

The parts list reflects the four-sink scope: four 30-inch supply lines, eight supply-line extensions, two three-eighths-inch compression couplings, three inch-and-a-half flanged tailpiece extensions and four inch-and-a-half bag traps. Inch-and-a-half angled drain fittings were also listed. The useful result of this visit is a fixture-by-fixture account: two Flex room sinks working, a Foundations adult drain working with a faucet issue identified, a Foundations children's faucet issue still preventing a drain test, and a debris-blocked toilet restored to operation.

Commercial work means working around people who have a job to do. We hook it up, test it, and tell you plainly what still needs attention.
