I need to replace the washers on a couple of Supataps. One takes a 1/2" washer and the other is 3/4", I understand. (I haven't dismantled the taps yet, as I don't want to disturb anything until I have the parts.)
A couple of questions:
Can I just use ordinary flat washers? Or do I need to get a washer that comes on a brass jumper, ready-made?
Are domed washers better?
