How to install outdoor kitchen sink plumbing?

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

Re: Outdoor Kitchen Sink plumbing

Welcome to the Bunnings Workshop community @Bruce69. It's terrific to have you join us, and many thanks for your question about connecting a sink to a sewer pipe.


Is this a septic tank? If so, you typically wouldn't plumb a sink into one as it adds excess water, which will fill the tank quicker. You'll find that regulations require you to enlist the services of a qualified plumber to connect your sink, as it is considered plumbing work. I trust they'll be able to provide guidance on an appropriate connection method.

Please let me know if you have any questions.
