In the service compartment where the plumbing and sewer connections are I have a hot and cold water low point drain levers. They are just black plastic switches that turn from the 6 o'clock to 9 position. One of mine has become so brittle that it has broken off.
They're just connected to the brass tap fixture with a small Philips screw.
I haven't been able to find a replacement lever.....anyone had to replace of these?
Thanks....Ron
