User Reviews & Q&A Summary
An OEM Weil-McLain boiler pressure relief valve used to protect a hydronic heating system by relieving excess pressure when the specified ASME-rated 30 PSI relief valve is required.
Key Features
- Boiler pressure relief valve
- 30 PSI relief valve
- 3/4" NPT male connection
- OEM replacement
- Listed as replacing 511-546-920
Compatibility & Applications
- Equipment model lists are not provided in the available sources; compatibility must be confirmed using the unit's full model/serial and the manufacturer-specified replacement part number.
- Must only be used where the manufacturer specifies this exact part number: 383-500-095 (including where it is specified as the replacement for 511-546-920).
Installation & Operation Notes
- Installation should be performed by a qualified boiler/heating service technician.
- Reference the boiler's installation/service manual and parts list for the correct relief valve location, piping/discharge requirements, and startup/checkout procedure after replacement.
- Follow all applicable codes and manufacturer safety instructions for pressure relief piping and safe commissioning.
Maintenance & Troubleshooting
- This valve is commonly replaced when the existing relief valve is leaking/dripping or shows mineral buildup/corrosion that can prevent proper sealing.
- If leakage continues after replacement, follow the boiler service documentation to confirm system pressure control is correct (relief valve weeping can also indicate an underlying system issue).
Certifications & Compliance
- ASME is explicitly identified for this relief valve in the manufacturer parts catalog (ASME 30 PSI relief valve).
User Reviews & Q&A Summary
- Review themes: Most feedback describes it as the exact replacement that fits and works as expected, commonly installed to stop a prior valve that was leaking/dripping. Several reviews mention a tight seal ("no more dripping") and successful replacement after mineral deposits damaged the old valve.
- Q&A themes: Compatibility questions focus on whether it's only for "Ultra Gas" boilers. SupplyHouse staff notes it is also used on a Weil-McLain WTGO oil boiler, reinforcing that selection should be confirmed by the boiler's parts list/part number rather than the category label.

I would buy this product again and again.
The new pressure relief valve worked perfectly when installed. The previous on was leaking water and required replacement before turning the boiler on for the winter.

exactly the same
my weil mclain cgi gold series 2 boiler's relief valve had a lot of mineral deposits inside and broke, and this was the exact replacement. works great, no complaints, just a tad pricey compared to other models that does the same thing. But I don't mind paying a little bit more for the exact same part

Product Q&A
1 Question1 Question
Q: Why is it "for Ultra Gas Boilers" ? I always thought 3/4" male NPT and 30 PSI is "enough said" for any T&P valve for a boiler. What is so special about it and therefore it wouldn't be a fit for my Weil-McLain WTGO oil boiler ? Thanks.
