I live in a triple-decker condo built around 1909. The third floor condo just replaced their entire bathroom. While it may just be a coincidence, the pipes feeding their unit have had a LOT of water hammering since the work was done. This is especially true with the hot water where the noise is especially loud at the water heater in the basement (I live on the first floor and am the one who gets the brunt of the noise at 5 a.m.!!).

Any thoughts on how to fix this other than with arrestors? As an FYI - their plumber wants to install water hammer arrestors. This seems unnecessary since there was not any issue at all before the work began.

Also, does anyone have any ideas on why this would it start just after the construction? Thanks...

There are two types.

The "true" water hammer is a single bang, maybe followed by a couple of rattles. It is caused when realatily fast moving water is SUDDENDLY shut off. Most commonly seen with soleniod valves in clothes and dishwashers.

But can be causes by some newer valves that are quicker acting.

This type needs a hammer arrestor near the valve(s)

The 2nd type is a noise that continuses as long as the water is flowing. It can vary from a machine gun bang, bang, to a fast chatter, to high pitch sound. And sound might change with amount of water.

That is caused something that is in the water pipe that can move around as the water flows. Most often it is caused by a bad washer or loose screw holding the washer on the valve. But it could also be something that got into the pipe.

This is fixed by getting finding and fixing the problem.

Thx. This is definitely the 2nd type - more of a constant machine gun sound. It is especially loud right at the hot water heater in the basement.
