![]() ![]() Either get a 1/2 ' Mip x slip joint trap adapter, or get a smaller trap. Getting a smaller trap is probably much easier than un-threading the trap adapter, but its up to you. You either have to change the trap adapter to 1.5' or change the Trap to 1.25'. Oh, the dishwasher stand pipe in the photos although looks like crap, does meet code requirements. I think your trap is 1.5' and the trap adapter coming out of the wall is 1.25'. If the P-trap’s piping and connections appear to be lined up fairly well and in good shape, there’s a good chance you can fix the leak in less than 2 minutes by properly tightening the slip-joint nutsthe collar-like connectors that join together sections of pipe. Hopefully this understanding is correct…īTW,, I found a link to what COLORADO state regulations are in relation to the 2018 IPC. Inspect the P-trap for signs of obvious problems. ![]() So in this particular situation, IF there was an additional trap on the horizontal leg after the Y fitting, it would be considered a double trap. Connecting the drain hose on a dishwasher is an equally simple plumbing job. my bad.) I guess it’s all on how far one digs into the overlapping codes and how one may interpret what is written. (can’t find the code source to quote, didn’t save it I guess. I read elsewhere that each “well” of a kitchen sink may have it’s own trap and discharge into the DWV pipe via a Y fitting. In the 2015 IPC section 1002.1 the very last sentence states “a fixture shall not be double trapped”. Ok, so I did some more digging and came up with 2 separate “official” answers. The waste line of a domestic dishwashing machine discharging into a kitchen sink tailpiece or food waste disposer shall connect to a deck-mounted air gap or the waste line shall rise and be securely fastened to the underside of the sink rim or counter. ![]() If you are on the fence just pick up the phone and contact a local plumbing contractor you trust.ĭomestic dishwashing machines shall discharge indirectly through an air gap or air break into a waste receptor in accordance with Section 802.2, or discharge into a wye branch fitting on the tailpiece of the kitchen sink or the dishwasher connection of a food waste disposer. You will get the choice to install pre-made traps, dishwashers, or the updated appliance that doesn’t need to have any traps. The difference between DK-100 and DK 105 is minimal. It has an automated drainage system connected with the house drainage system. On the upside the noise is reduced piping this method instead of discharging into the disposal or branch tailpiece. When installing the dishwasher, you need to connect all the components accordingly. I would have drained the dishwasher into the disposal or used a branch tailpiece on the left bowl. The dishwasher drains into the standpipe with an air break which is acceptable for a domestic dishwasher. You have a 2” pipe picking up the sink and dishwasher. ![]()
