We recently had the tub faucets replaced and had to shut off the water for the house. Since turning the water back on there is now a banging when the toilet is refilling. It doesn't happen every tone the toilet is flushed though. It's been over a month now so I would think any air bubbles in the pipes would be gone by now. Any suggestions?

Clean the fill valve washer...
