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. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Barnstable Town, a pro matches the fix to the symptom.
The match
