Hi, Im planing an outdoor kitchen set up with a sink. My sink will be positioned about 300 mm away from my sewer (septic) inspection shaft. Can i get a Holman Junction DWV PVC Female x Female 100x 50mm x 45deg and dig down to fit this on the inspection shaft pipe ? thus giving me a 50mm outlet to plum up to my sink s-trap?. The inspection shaft pipe will be extended from the Holman junction and capped as it currently is at the same height. Thanks for any advice, Bruce
