Installing a whole house drain
Posted by Paul Ahaus on April 25, 2002 at 15:28:26:
I recently bought a model home with a 1" water feed. I want to install a drain valve so I can drain the entire water system, without disconnecting the union at the meter. I have a shutoff valve before and after the meter. What kind of drain do I use? Do I have to Tee off into this drain valve?
