Thread: 3/4" by 3/4" brass check valve?

  1. #1

    Default 3/4" by 3/4" brass check valve?

    Is there such a thing as a 3/4" by 3/4" brass check valve for water heaters? My current setup has brass nipples going into the water heater and I don't know if they're check valves or not. Should I just disconnect the hot water line and use a screwdriver to see if there's a check valve in the brass nipple or? Thanks, Ken Reed

    they make heat trap nipples but I have never seen them in brass so I don't think yours are...definately not check valves...

    I doubt what you are looking at is a check valve. But yes they do make 3/4" check valves. Here are a couple pictures of them.

    Default Why I wanted to know

    Thanks for the responses. My 50 gallon gas Richmond water heater is making a clicking noise lasting 1-2 seconds every time the hot water is run. The noise is coming from the area of the brass nipple on the hot water side. I was told it was probably the check valve. Looks like it's not. Thanks, Ken Reed

    The clicking noise is common with ball-check heat trap nipples. But the ones I have seen were galvanized, not brass.

    Default noise

    The noise is probably coming from the heat trap on the hot OR cold connections to the heater. Who ever told you it was a check valve problem was wrong.

    Default Heat trap

    I have no trouble showing my ignorance in admitting I don't know what a heat trap is, looks like, or how you check/replace one. Is it part of the water heater or part of the hot/cold water lines attached to the water heater? Any information would be greatly appreciated. Thanks , Ken Reed
