Plumbing question ?
One question before I have to call a plumber and pay several $$$ because the nearest one lives 1 1/2 hours away. For the 3 compartment sink and hand wash sink I'm filling out paper work they are asking for Sewage Disposal and asking if it is air gap,Air Break or Direct Connect. I'm guessing Air Gap as all 4 sinks are connected togather then dump into my gray water tank which has a vented double check valve on the tank. Also for the water supply I'm totaly lost with what to put down They are asking for one of the following AVB,PVB,RPZ,HB,VDC.
Thanks in advance for saving me or should I say my wife :) some money
