Ines Toller let go of the cart handles when Mara reached her, and put her hands under her armpits.
“It stopped at dawn,” she said. “Just stopped. The motor hums, and nothing comes out.” Her voice was quiet and very level, the voice of somebody who has decided not to be a nuisance. “The child’s room is cold.”
Mara watched the widow’s hands go under her arms. The knuckles were white, the fingertips pale and puffy, the backs chapped raw. The cold had already reached them. It had reached them days ago.
“We’ll look now,” Mara said.
She untied the clothesline and lifted the pump off the cart. It was heavier than it looked, a squat steel box about the size of a stove kettle, with a motor housing bolted to one end and a pressure manifold on the other: a short thick pipe stub with a collar around its throat, where the pump’s output joined whatever line it fed. She carried it to the bench and set it down under the work lamp.
Tavin was at the back of the yard, beyond the melt pit, with Arlo, wrestling a seized flange off a section of conduit. She could hear them: Tavin’s low curses, Arlo’s wheeze, the ring of a hammer on a drift. He had not seen the cart come in.
She left him where he was.
She plugged the motor into the bench socket. It came on with a low tired hum, and she put her palm on the housing and felt the hum come up through her palm, and under it, as she had known there would be, a squeal. Thin, high, almost too high to hear in the air. She moved her hand along the housing to the manifold, to the collar. The squeal was there. It was the collar: a worn pressure collar, its inner face polished smooth by years of flow, slipping on the stub so the pressure leaked back into the pump instead of going out the line. That was why nothing came out. The motor turned and the pressure built and the collar let it all slide home again.
And under the squeal, fainter, something else.
She pressed her palm on the manifold and closed her eyes. The sound lay further along than the collar, past the stub, in the line the pump fed: a dull note, cold, with a rough edge to it, like a voice that has been shouting all night. Old metal. Thin metal. Tired.
“The collar’s worn,” she said, opening her eyes. “The pipe behind it is older than the collar.”
She said it fast. She said it before she had looked at anything except the collar under her hand. She had not turned the pump around. She had not read the plate on its back.
Ines Toller looked at her with the faint hopeful attention of someone who does not understand the words but understands that they mean the thing can be fixed.
“Can you do it today?”
“Yes.”
Mara went to the parts rack on the wall behind the bench. The yard kept collars in a row of labeled bins, by stub size and by rating. She found the stub size. The bin held two kinds: the old pattern, the same rating as the worn one, and a newer pattern, heavier, stiffer, rated for more pressure, which the dock guild used on its crane lines. She looked at them both.
The heavier collar would seal harder. It would not slip. The pump would push everything it had into the line, and the room would be warm, really warm, not the thin grudging warmth an old pump gave when its collar was half gone. The widow’s hands would stop hurting.
She told herself it was the better part. She told herself that a stronger collar was simply a better repair, that she was making the pump do the job the job card said, low output, collar?, and doing it properly. She told herself, in a smaller voice, in a part of her head she avoided looking at directly, that Tavin was at the back of the yard with a seized flange and would not come for half an hour, and that she could do this, start to finish, without anyone standing at her shoulder telling her to read the plate. She could show him. She had found the seam at the third turn of the bore and he had said keep doing that. She could keep doing that.
She took the heavier collar.
It took twenty minutes. She cut the old collar off with the small bar, cleaned the stub with emery cloth until it shone, warmed the new collar on the bench stove and drove it on with a soft mallet, a quarter turn at a time, listening. When it seated, the stub gave a single clean note, solid as a closed door.
The plate was on the back of the pump. She did not turn it around. The plate listed the pump’s rated flow and rated pressure, the figures for the pump itself, stamped at a factory forty years ago. The pipes in the widow’s building were not on the plate. Pipes were never on a pump’s plate. To know what the pipes could take she would have had to ask what pipes they were, how old, what metal, what joints; she would have had to go and look at them. She thought of the dull note she had felt past the stub, the old thin tired line, and she put it out of her mind, because it was not the job. The job was the collar.
She plugged the motor in.
It came on. The hum was different now, fuller, and in a few seconds hot water began to spit from the manifold’s test port into the bench bucket, then to run in a steady stream, smelling of hot iron and machine oil. She held her hand under the port. It was hot. Properly hot. Steam came up off the bucket and drifted toward the cart, where the widow was standing, and rolled across the cart’s bed and over the widow’s hands.
Ines Toller laughed. Once. A small, startled, almost embarrassed sound, as though she had not expected to and was not sure what to do with it.
Mara unplugged the pump and loaded it back on the cart.
She walked it home herself. The widow tried to take the handles and Mara would not let her. Coil Stair was a narrow lane on the slope above the conveyor bridge, a row of four-story tenements built against each other like books on a shelf, and number six was near the top. They carried the pump up two flights of cold stone stairs between them, Mara at the heavy end. The flat was two rooms: a kitchen with a table and two chairs and a cold stove, and a small back room, barely wider than a bed, where a child of about five lay asleep under three blankets and a coat. The pump’s line ran up the wall of the back room, a grey iron pipe as thick as Mara’s wrist, painted over many times, bracketed to the plaster, running across the ceiling just above the child’s bed and on through the wall to the radiator in the kitchen.
Mara connected the pump at its socket by the kitchen door. She kept her eyes off the pipe on the ceiling. She told herself she did not need to.
She switched it on.
The hum filled the flat. The radiator in the kitchen ticked, then ticked again, faster, then began to give off heat: first a faint warmth, then a real warmth, the kind that made the air shimmer over the iron. Ines Toller stood by it with her hands out, palms down, and said nothing at all.
There was a clock on the kitchen wall, an old brass clock with a cracked face. Mara looked at it and noted the time. She told herself she was noting it to see how long the heat would hold, which was good practice, which was what Tavin would have done. She did not tell herself why she wanted to know.
“Thank you,” Ines Toller said.
“It’s not finished.”
The widow turned from the radiator and looked at her. Her face, in the warm air, had lost a little of its greyness.
“It’s warm,” she said, and pulled her shawl tighter around her shoulders with her right hand. Her left hand stayed in the fold of the shawl, pressed against her chest. Mara saw it there, white at the knuckles, still cold.
Mara picked up her tools.
She had told Tavin she would read the plate. She had not read it. She had told him she would do the job with him. She had not called him. She stood in the doorway of the widow’s flat with her tool bag on her shoulder and the heat on her face, and she was already thinking about something else: the register, the dates on the wall, the curve that leaned inward through Hearth. The question at the bottom of her notebook page. She was thinking about who chose the order. She was not thinking about the pipe.
She went down the first flight of stairs.
Behind her, through the open door at the top, she could hear the pump humming and the radiator ticking, and the old brass clock on the kitchen wall. On the landing she glanced back up, out of habit, and through the doorway she could see the clock’s cracked face. Nine minutes. Ten.
Above the child’s bed, she knew without seeing it, the grey iron pipe ran across the ceiling, carrying more pressure than it had carried in forty years.
She went on down the stairs. The clock’s long hand moved. Eleven minutes. She heard, very faintly, from the top of the building, a single high tick in the iron, like a fingernail on a pane of glass.
