    Installing Floor Drain in Existing Basement
    I would like to install a floor drain in an existing basement to drain my high efficiency furnace, my air conditioner coil, and my hot water heater (to clean it). About 10 feet from my proposed location I have a vertical 2" ABS pipe along the wall draining upstairs sink and dishwasher. This pipe is vented through the roof and continues down through the concrete eventually reaching the sewer. I cut out sufficient concrete around the pipe to be satisfied that I have more than enough fall from drain to this pipe. How should I proceed. I don't believe they make those old bell trap basement drains anymore. Will I have to install a P-trap in the line between the drain and the pipe. Is it within code to just run a 2" line from the drain to the existing vertical and make a connection with a sanitary tee? Help!

    I think this is what you need Buy "Sioux Chief" P Trap Floor Drain at BuyHardwareSupplies.com It is within code depending on what you plan to drain into it. I would go up to a 3" line even though you won't be draining that much. I can save you a lot of trouble since the concrete won't be easy or fun. Just buy and install a condensate pump. CB15 Beckett Condensate Pump - FilterAce - Incredible Prices on Air Filters and Furnace Filters This will handle the furnace and you can run a garden hose for the once or twice per year water heater flusing.

    Thanks Bob. I already ordered the floor drain you requested. I have a condensate pump now, but we travel a lot and the previous pump failed once when we were gone.

    Condensate pumps can be a bit funky. The pump rarely fails but the little float can forget to float and then you got troubles. I understand your situation. So if you break up the concrete to tie to the stack be sure to keep a 1/4" per foot slope. I hope you kill the fuel to your water heater and shut down your main when you are gone. I live in a lake community with lots of weekender. Each year we have over $1,000,000.00 in damages from leaking and burst pipes, some as small as the toilet fill line. I also got a neat type of thermostat that allows you to control the house temp from your cell phone if you are interested. Great for travelers who want to come home to a comfortable home.
