I never knew there were so many different manufacturers of the same item to choose from. Holy crap. On the bright side however my father-in-law has been a plumber for about 50 years and after a quick phone call in his direction I narrowed my search down to well, this one. The only thing he cautioned me on was to look at the old one before you replace it and make sure the new one has the same markings PSI etc etc, and other than that it's pretty easy. Shut off the water supply, relieve the pressure, unscrew the old one and with the use of a little bit of thread tape, screw this one on and snug it down. The whole repair took me about 4 minutes. ## Features - 3/4" male NPT threaded inlet for connecting to a female NPT threaded connection. - ALL brass body and stainless steel spring for corrosion resistance. - Designed for protection against excessive pressure only - Universal 3/4" size is suitable for most U.S. residential usage. - Easy and fast installation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CCJ7QZQ7 | | Best Sellers Rank | #11,940 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Relief Valves | | Brand Name | HYDRO MASTER | | Customer Reviews | 4.4 4.4 out of 5 stars (193) | | Exterior Finish | Brass, Stainless Steel | | Included Components | Relief Valve | | Inlet Connection Size | 3/4 Inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 3.2 x 1.6 x 1.8 inches | | Item Type Name | Relief Valve | | Item Weight | 0.45 Pounds | | Manufacturer | HYDRO MASTER | | Material Type | Brass | | Maximum Pressure | 30 Pound per Square Inch | | Model Number | 0571101 | | Number of Ports | 2 | | Outlet Connection Size | 3/4 Inches | | Outlet Connection Type | NPT Thread | | Specification Met | CSA | | Thread Type | NPT | | Unit Count | 1.0 Count | | Valve Type | Pressure Relief Valve | ## Product Details - **Brand:** HYDRO MASTER - **Exterior Finish:** Brass, Stainless Steel - **Inlet Connection Size:** 3/4 Inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 3.2 x 1.6 x 1.8 inches - **Material:** Brass - **Maximum Operating Pressure:** 30 Pound per Square Inch - **Number of Ports:** 2 - **Outlet Connection Size:** 3/4 Inches - **Outlet Connection Type:** NPT Thread ## Images ![HYDRO MASTER Safety Relief Valve With 3/4 Inch Thread 30 PSI ASME Hot Water (30 PSI) - Image 1](https://m.media-amazon.com/images/I/61yQEgmVl8L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value *by A***R on March 26, 2026* Easy to install and works grest ### ⭐⭐⭐⭐⭐ Plumber recommended.. *by W***N on August 28, 2025* So when my boiler system started leaking out of this particular valve, I was of course in the market for a new one.
