Water hammer arrestors and surge tanks both tame pressure spikes, but they solve different problems. Knowing which one you need comes down to what is causing the bang.
The arrestor
A water hammer arrestor is a small sealed chamber that absorbs the shock from a fast-closing valve, and it is sized to the fixture.
The surge tank
A surge or expansion tank handles slower pressure changes, like the thermal expansion from a water heater.
The cause
A bang when a valve closes points to water hammer, while a relief valve that drips points to thermal expansion.
The placement
Arrestors go near the fast-closing valves, and an expansion tank goes on the cold line near the heater. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Manteca, a pro matches the fix to the symptom.
The match
An arrestor stops the bang from a fast-closing valve, while a surge tank handles slow thermal expansion. Fixing the wrong one leaves the problem.
