Product details

The Pentair 460925 is the pressure relief valve for pool and spa heaters, a genuine Pentair part.

What it is there for

A relief valve is a safety device and nothing else. If pressure inside the heater rises past the valve setting, whether from a closed valve downstream, a blocked line or a heater firing with no flow, the relief valve opens and lets it out. Everything else in the system assumes that valve works.

When to replace it

A relief valve that has lifted once often will not seat again cleanly, and one that has been sitting in pool water for years can corrode internally. A weeping or dripping valve is telling you it is finished. It is not a part to adjust, plug or leave for later. Confirm the port size and the valve part number on your heater before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

What does a pressure relief valve do?
It is a safety device. If pressure inside the heater climbs past the valve setting, the valve opens and vents rather than letting the pressure keep building.
My relief valve is dripping. Can I just tighten it?
No. A valve that seeps has usually lifted once and no longer seats, or has corroded internally. It gets replaced, not adjusted.
Which heaters does it fit?
Pentair lists 460925 as the pressure relief valve for pool and spa heaters. Confirm the port size and the valve part number on your heater before ordering.
Is this a genuine Pentair part?
Yes. It is Pentair part number 460925.
