Dad fixes the washer

Text 1: No Need for a Plumber, by Alistair Munro

An original novel extract.

Dad said there was no need to call a plumber, which is how the kitchen ended up underwater. The washing machine had been making a noise like a cement mixer for a week, so on Sunday morning he pulled it out from the wall, lay on his back on the lino and began unscrewing things. I passed him the spanner. Then the bigger spanner. Then he unscrewed a grey hose at the back, and the water that had been sitting inside the drum came out all at once, a cold grey wave that soaked his jumper and raced across the floor towards the cat’s bowl. The cat left the room without a sound. Mum appeared in the doorway in her dressing gown and looked at the water, then at Dad, then at the phone. ‘I’ll find the number,’ she said.
