    Question Ball valves - are they created equal?

    I need to replace my 3/4" main shutoff ball valve as
    1. the handle is rusting through
    2. on a recent pipe replacement job there was a small amount of leakage (maybe this is normal)
    3. I want to upgrade my main supply through the house to 3/4" - and I'm not sure if trying to attach a 3/4" male fitting to this valve will work.

    I have 2 in my possession - a chinese Matco and an Italian Mueller - both sweat. My plumber swears by Watts and as this is a pretty important valve - I'd very much appreciated the learned opinions on this forum as to what they would install.

    Also - my current valve is a compression - I would like to replace with a sweat fitting - is this advisable? I'm in NJ and I'm assuming the main pipe inlet is thicker copper.

    That's a compression valve. Wow. Showing my greeness. Never seen a valve like that.

    Your plumber seems to be spot on with his choice. Trust the man.

    yep - its not a compression - just a threaded valve.

    Seems I have 2 choices - try to remove the threaded reducer fitting at the top to replace with a 3/4 straight male

    or

    get the water shut -off and replace the whole valve

    any suggestions?

    wouldn't any solution be just as easy?

    Shutting off the ball valve, cutting the copper, unscrewing fitting from the valve, screwing in new copper mip adapter and pipe?

    Shutting off city line/meter, cutting copper, sweating on new ball valve, sweating on new 3/4" tubing?

    of the valves you have, I'd use the Mueller.

    The valve still works? Does it leak? If it works and is not leaking why not jsut change the handle and nut? If you can not find a new handle just take the old one off can clean it up and hit it up with some rustoleum.

    Thanks for your reply Brent - your probably right - its just in my town they want $60 to shut off the water at the street - the access point is visible (and brand new - as they had to replace and test it last fall)

    Not only is it the money - its syncing up with the water guys to get them out on a weekday at the right time.

    If I could turn it off myself.... - I would go for the new valve
