Do your pipes bang or knock when you shut off a tap or the washing machine stops? That's water hammer, and it won't fix itself.
We install and repair water arrestors to stop it for good. Licensed Toronto plumbers, free inspection, written guarantee.
If that’s your house, you’ve got water hammer. Read on.
The problem: fast-moving water hits a valve that slams shut, and the shock bangs back through your pipes.
The fix: a water arrestor cushions that shock. Fitted in the right spot, the banging stops, your pipes go quiet, and your fittings and appliances stop taking a beating every time the water shuts off.
It’s one of a few causes, and knowing which one is the fix:
Hearing it daily? Call 416-231-3331 and we’ll stop it before it does damage.
Yes. It’s not just noise.
Every bang is a shock to your plumbing. Over time it loosens fittings, wears out washing machine and dishwasher valves early, and stresses the joints. Left long enough, it can crack a pipe or a joint and turn a noise into a leak.
The bang is cheap to fix. The leak isn’t.
This is the most common cause we see.
A washing machine or dishwasher shuts its water off with a fast electric valve. The flow stops in an instant, and the pipes bang. It often starts right after a new appliance goes in.
The fix is a small arrestor fitted right at the appliance, where the shock starts. Quiet, quick, done.
No guessing. Here’s how it goes:

That’s water hammer. When a valve closes fast, the moving water slams to a stop and the shock bangs back through your pipes. A water arrestor absorbs that shock and stops the noise.
It can be. The repeated shock loosens fittings, wears out appliance valves early, and stresses pipe joints. Left long enough, it can crack a pipe or joint and cause a leak. It’s worth fixing early.
As close as possible to the valve or appliance causing the bang. For a washing machine or dishwasher, that’s right at the appliance. We find the source and fit it where it works best.
It’s likely waterlogged or worn out. Try shutting off your main water, draining the lines from the lowest faucet, then turning it back on. If the banging returns, the arrestor needs replacing, and we’ll handle that.
New appliances use fast electric shut-off valves that stop the water in an instant, which triggers the bang. It’s very common. A small arrestor at the appliance fixes it.
It varies, but they don’t last forever. Over time the cushion inside gives out or waterlogs and the banging returns. When that happens, it’s a straightforward replacement.
