It is the Watts 25AUB By Pass Model. The description says, "Allows water to escape back into the supply main line before it can affect the relief valve". Is it still true I don't nned the expansion tank if I get this PRV? : : I was told that this reducer has a built in expansion valve and I didn't need a water expansion tank. Is this true? : If this simply has a bypass, then you probably need an expansion tank. I have never seen a PRV with a built in expansion valve (where does the expanded water go?). What brand and model is this?
