Chapter 4 - The Leaking Faucet

Saturday morning, Louis arrived at the Maple Street building at seven with a toolbox, two thermoses of coffee, and Ben in the passenger seat.

Ben looked at the row of aging brick apartments.

“You said six faucets.”

“Six units.”

“So maybe more than six faucets.”

“Correct.”

“Can I help?”

“You can observe.”

“That means no.”

“That means you can hand me tools and avoid touching anything connected to electricity, gas, sewage, structural walls, angry tenants, or unknown liquids.”

“That leaves almost nothing.”

“Welcome to maintenance.”

The property manager, Ray Donnelly, met them at the entrance.

He was a broad man with a red beard and a ring of keys large enough to anchor a boat.

“That your grandson?”

“Ben.”

Ray shook his hand.

“You any good with plumbing?”

Ben looked at Louis.

“I’m in training.”

Louis grunted.

“Unpaid training.”

Ray laughed.

The first apartment had a bathroom faucet that would not stop dripping.

Louis removed the worn cartridge while Ben watched from the doorway.

“How much water does that waste?” Ben asked.

“Depends how fast it drips.”

“Can we measure it?”

The tenant, an elderly woman named Mrs. Vega, smiled from the hall.

“You can measure anything you want if he makes that sound stop.”

Ben found a measuring cup in her kitchen. They placed it under the drip for five minutes.

Thirty milliliters.

Ben did the math on his phone.

“That’s over eight liters a day.”

Louis looked at him.

“You sure?”

Ben recalculated.

“About eight point six.”

Mrs. Vega stared at the faucet.

“That little drip?”

“Every day,” Ben said.

“What’s that in a month?”

Ben’s fingers moved again.

“More than two hundred fifty liters.”

Mrs. Vega crossed her arms.

“Louis, why didn’t you tell me my sink was trying to open a swimming pool?”

Louis smiled.

“Because I just got here.”

Ben wrote the number in his notebook.

By the fourth apartment, the notebook had become a project log.

Drip rate.

Estimated daily waste.

Part replaced.

Approximate repair cost.

Ben asked every tenant permission before measuring.

Louis noticed that.

He also noticed Ben did not ask any of them how much their water bills were.

Another lesson had landed.

In Unit 3B, they found a leak beneath the kitchen sink.

A slow drop formed at the compression fitting, slid down the pipe, and landed in a plastic bowl the tenant had placed underneath.

Ben crouched beside Louis.

“Can a sensor go here?”

“Probably.”

“Battery powered?”

“Easier.”

“What if it just lights up?”

“People don’t look under sinks much.”

“So buzzer.”

“Quiet buzzer.”

“Why quiet?”

“You want them warned, not evacuated.”

Ben wrote QUIET BUZZER.

Ray leaned against the counter.

“What are you two building?”

“A leak alarm,” Ben said.

“For school?”

“Museum challenge.”

Ray nodded solemnly.

“You should make one that calls the landlord and tells him he’s cheap.”

Louis looked at him.

“Your building.”

“Exactly.”

The final repair took longer than expected. A corroded shutoff valve refused to turn. Louis braced one arm against the cabinet and pulled.

Pain flashed through his right wrist.

He stopped.

Ben noticed.

“What happened?”

“Nothing.”

The word came out automatically.

Ben stared at him.

Louis sighed.

“Wrist.”

“How bad?”

“Not bad.”

“Truth you can explain.”

Ray raised his eyebrows.

Louis muttered something under his breath.

“Old sprain. I twisted it.”

“Do you need to stop?”

“No.”

“Do you need help?”

Louis opened his mouth.

Closed it.

Then handed Ben the flashlight.

“Yes. Hold this exactly here.”

Ben smiled without triumph.

That made it easier.

They finished just after one.

Ray counted cash into Louis’s hand in the parking lot.

“Six units plus the valve. I added twenty for the extra hour.”

“You don’t need to.”

“I know.”

Louis looked at him.

Ray shrugged.

“The owner approved it.”

Louis accepted the money.

Ben watched but did not ask how much.

On the drive home, he opened his notebook.

“I think we can make the sensor from cheap parts.”

“We?”

“You said I could help.”

“With building. Not buying.”

“I have seventeen dollars.”

Louis glanced at him.

“For something you want, remember?”

“I want parts.”

Louis considered that.

“All right.”

Ben sat straighter.

“But I match what you spend, up to ten dollars.”

“Why?”

“Because I want to.”

“That’s not a reason.”

“It is the exact reason.”

Ben smiled.

“Okay.”

They stopped at a hardware store.

Ben chose a plastic project box, a small battery holder, wire, and two metal contacts. The electronics store next door sold a tiny buzzer and LED.

The total came to $13.84.

Ben counted seven dollars from his envelope.

Louis paid the rest.

No money face.

He was proud of that.

At home, they cleared the kitchen table.

Ben sketched.

Louis drilled two small holes in the project box.

By late afternoon, they had produced something ugly, crooked, and completely nonfunctional.

Ben stared at it.

“It doesn’t work.”

“That is an accurate technical assessment.”

“Why?”

“Could be wiring.”

“We followed the diagram.”

“Diagrams have been known to lie.”

Ben laughed.

Louis checked the contacts.

“Battery?”

“New.”

“Buzzer?”

“New.”

“Connections?”

They inspected each one.

Finally Ben pointed.

“You put this wire on the wrong side.”

Louis looked.

He had.

“I was testing you.”

“No, you weren’t.”

“I was conducting an instructional failure.”

“You messed up.”

“I prefer my phrase.”

Ben moved the wire.

They placed two drops of water across the contacts.

The LED flickered.

The buzzer made a weak electronic chirp.

Ben’s eyes widened.

“Again.”

Louis added another drop.

Chirp.

“It works.”

“It barely works.”

“It works.”

Ben jumped from his chair.

“Mom needs to see.”

“Call her.”

Dana answered on video.

Ben held the phone too close to his face.

“We built it.”

“Built what?”

“The leak thing.”

He turned the camera.

Louis waved.

Dana laughed.

“What am I looking at?”

“A prototype,” Ben said.

“It looks like an alarm clock lost a fight.”

Louis pointed at the screen.

“You see what I put up with?”

Ben demonstrated.

The buzzer chirped.

Dana clapped.

“That’s actually clever.”

“It needs to be louder,” Ben said. “But not evacuation loud.”

“Good standard.”

“And Grandpa wired it wrong.”

“I did not call to be attacked.”

Dana smiled.

Then Louis noticed her face tighten as she shifted in her chair.

“Knee?”

She nodded.

“Bad day.”

Ben’s excitement dimmed.

“You okay?”

“I’m okay.”

“Truth you can explain,” he said.

Dana looked at Louis.

“Oh, so that’s a family law now?”

“Apparently.”

Dana adjusted the phone.

“Okay. Truth. Physical therapy hurt today. I’m tired. I’m frustrated. I am still getting stronger.”

Ben nodded.

“Do you still come home Thursday?”

“Yes.”

“For sure?”

“For sure.”

Louis heard the caution behind her certainty.

“Transportation set?” he asked.

“The center van can bring me.”

“You sure?”

“Yes.”

“I can pick you up.”

“You have work.”

“I can move it.”

“No.”

Dana’s voice sharpened.

“Dad, you don’t get to make Ben stop carrying everything and then carry everything yourself.”

Ben looked from the phone to Louis.

Louis said, “This is different.”

“No, it isn’t.”

“I’m your father.”

“And I’m thirty-four.”

“Your age is not relevant.”

“It is very relevant to me.”

Ben covered his mouth to hide a smile.

Dana continued.

“The van is covered. Use your work hours.”

Louis leaned back.

“All right.”

Dana blinked.

“That was suspiciously easy.”

“I’m evolving.”

“Should I alert the hospital?”

“Goodbye, Dana.”

“Love you too.”

Ben took the phone to his room so he could show her his project drawings.

Louis stayed at the table with the prototype.

His wrist ached.

He flexed it.

Not serious.

But not nothing.

He opened his wallet and counted the money Ray had paid him.

Enough for the water bill.

Enough for groceries.

Enough to put twenty aside for the truck belt.

Not enough for everything.

But possible.

The next morning, Hannah emailed parents a reminder about the Young Problem Solvers challenge.

Louis showed it to Ben over breakfast.

Ben read the requirements aloud.

“Define a real problem. Build or model a solution. Measure the effect. Explain who it helps.”

He stopped.

“Measure the effect.”

“You already did.”

“The faucets.”

Louis nodded.

Ben grabbed his notebook.

“We need more data.”

“On a Sunday?”

“Science doesn’t know what day it is.”

“Science needs to wash dishes.”

“We can measure our sink first.”

The kitchen faucet had been repaired weeks earlier, but Louis deliberately loosened the handle just enough to create a controlled drip.

Ben frowned.

“You made it leak.”

“For research.”

“That feels wrong.”

“We are wasting one cup of water and then fixing it.”

Ben timed the drip.

They measured.

They calculated.

Then Louis tightened the handle.

Ben wrote a project title at the top of a clean page.

THE DROP GUARD.

He underlined it twice.

“What do you think?”

“Sounds like a superhero who fights plumbing.”

“That’s good.”

“It is?”

“People remember names.”

Louis nodded.

Ben drew the device beneath the title.

For the rest of the afternoon, they worked.

The second prototype was smaller.

The buzzer was louder.

The contacts were more reliable.

They placed it under the sink and dripped water onto the sensor.

Beep.

Ben cheered.

Louis laughed.

Then the phone rang.

Unknown number.

Louis answered.

“Louis Mercer?”

“Yes.”

“This is Carla Benson from the school district facilities office. Ray Donnelly gave me your number.”

Louis frowned.

“About what?”

“He says you do maintenance work.”

“Some.”

“We’ve got a temporary weekend opening. Three schools. Minor repairs, mostly plumbing fixtures and hardware. Four Saturdays to start.”

Louis sat straighter.

“What’s the rate?”

She told him.

It was better than Ray’s.

Not life-changing.

But steady.

“When do you need an answer?”

“Monday.”

Louis looked at Ben, who was still crouched beneath the sink with the Drop Guard.

“Can I call you back in an hour?”

“Sure.”

He ended the call.

Ben emerged.

“Job?”

“Maybe.”

“How much?”

Louis paused.

Ben winced.

“Sorry.”

“No.”

Louis surprised both of them.

“You can ask.”

Ben waited.

“It pays eighteen an hour. Six hours every Saturday for four weeks.”

Ben’s eyes widened.

“That’s—”

“Don’t calculate my income.”

“I was just—”

“I know.”

Ben put his phone down.

“Is that good?”

“It’s good.”

“Are you going to take it?”

Louis looked at his wrist.

He thought about the truck belt.

The water bill.

Dana coming home.

The list of things Ben had stopped asking for.

Then he thought about another list, one he had not written.

Pride.

Pain.

Silence.

He had spent years believing endurance solved everything.

Sometimes endurance was just delay with better posture.

“I’m going to ask what the work involves first,” he said.

Ben nodded.

“That’s smart.”

Louis looked at him.

“When did you become my supervisor?”

“When you wired the buzzer wrong.”

“Go clean your room.”

Ben laughed and disappeared down the hall.

Louis called Carla back.

He asked about the duties.

He asked whether heavy lifting was required.

He asked whether tools were provided.

He asked whether there was flexibility if his wrist needed rest.

Each question made him feel slightly exposed.

Each answer made the job feel more possible.

By the end of the call, he had accepted.

Afterward he sat alone at the table.

The Drop Guard gave one cheerful beep from beneath the sink.

Louis looked down.

A small puddle had formed under the pipe.

He groaned.

“Ben!”

Ben ran in.

“What?”

“Our research loosened the fitting.”

Ben stared.

Then he laughed so hard he had to hold the counter.

Louis tried not to.

He failed.

For five minutes, the apartment filled with the kind of laughter that made no practical improvement to their finances, fixed no injuries, paid no bills, and solved no adult problem.

It was still worth everything.
