If your old valves are like mine and you haft to twist the handle to
get the valve to open than I just cut those valves out by cutting
next to the valve itself and installing the new valve on the old
drain pipe. Really very strait forward job but you will need to clean
up old pipe so that your new pipe glue will addhess itself to the new
valve. Jon (the new valves work great and nice and easy!)
