hausdok Posted November 10, 2014 Report Share Posted November 10, 2014 Hi Guys, Just woke up and my brain is a little foggy this morning. Look at the photo; isn't there a restriction on length of an extension pipe to a trap - 18 inches or something like that This one is about three feet.

Chad Fabry Posted November 10, 2014 Report Share Posted November 10, 2014 1002.1 Fixture traps. Each plumbing fixture shall be separately trapped by a water?seal trap, except as otherwise permitted by this code. The trap shall be placed as close as possible to the fixture outlet. The vertical distance from the fixture outlet to the trap weir shall not exceed 24 inches (610 mm). The distance of a clothes washer standpipe above a trap shall conform to Section 802.4. A fixture shall not be double trapped. Quote Link to comment Share on other sites More sharing options...

John Kogel Posted November 11, 2014 Report Share Posted November 11, 2014 JFYI. the rule here is one meter or 3 feet approx. This allows the trap to be under the subfloor in a crawlspace or basement. This is done in island sinks sometimes. If the trap is below the floor, then the vent can be run under the floor to a vent stack in the wall. This works in Canada, but not in the USA. I am not a plumber and this could just be a local quirk in the rules.[] Quote Link to comment Share on other sites More sharing options...
