Review on 🚰 Mueller Industries 109 813 Valves 2 Inch: High-Quality and Reliable Plumbing Valve Solution by Dangelo Toliver

I use it to maintain the water level in a 55 gallon drum steamer. Works well! However, I did remove the internal O-ring on the valve assembly as it had deformed from the heat. Now it shoots water out of the end and out of the normal threaded part. I don't mind as the entire valve assembly is in my barrel. The actual sealing part of the valve is rubber and seems to hold up well to my faucet pressure and a 5" copper float on a 6" stainless steel stem. I inspected it today and it looked brand new after running it at 205F for about 12 hours. I also put some food grade o-ring grease on it to hopefully prolong life. (I ended up replacing it with a stainless steel float with silicone seals)
