About Us

Possessing a current Plumbing, Drainage, Gasfitting and Building licence, I have over forty years experience in the Industry.

Having been self employed carrying out all aspects of Plumbing & Drainage & Building works for over  20 years, also employed by MWS &D Board, Wyong Council, Sydney Water & Fair Trading as a Plumbing & Drainage Inspector also for 20 years.

The Plumbing Industry -  With regulations changing and about to change with the new PCA (Plumbing Code Aust) and the possibility of fines being introduced for Plumbing & Drainage  non - compliance. It is imperative that your sewer diagram meets Fair Trading criteria, to avoid the possibility of a fine or if you, the plumber/drainer just doesn’t have the time to do a sewer diagram, let Tri – City Sewer Diagrams help you.

Tired of coming home from work covered in mud or hot & sweaty just wanting to sit down and have a nice cold beer to realise that you have to do that drawing. Tri – City Sewer Diagrams will help you.

Using my experience as a P & D Inspector I can QA the sewer diagram at the same time. I will liase with you by phone to make sure all has been covered  in providing a professional drawing for you to submit to the authority.

Conveyancing - If you need a sewer diagram for the sale of a property, Tri – City Sewer Diagrams  can help you. Having vast experience with Solicitors and Conveyancers we know what is required to get that Sale Over The Line.
