The male and female toilets at the rear kept blocking. The cause was a level subfloor and poor fall, not people flushing the wrong things.
We rebuilt the amenities as one contractor, including the flooring: stripped suites and partitions, lifted vinyl and timber, cut out the 100 mm suspended sewer, ran new 100 mm PVC to the existing riser, laid new timber, vinyl and coving, and put the suites back. Basins and urinals stayed. We tested the work and issued a compliance certificate.
Commercial Drainage Plumbing Service
Preston, Victoria
This page is for facility managers, landlords and site contacts who have commercial toilets, floor wastes or sewer lines that keep blocking. Joniec Plumbing is a Knoxfield plumbing company (Victorian plumbing licence 46989, established 2005). We diagnose the drain, quote the repair, and stay on the job until the amenities are back in use.
A blocked cubicle is not always a user problem. Poor fall under the floor, undersized pipe, or a broken suspended sewer will refill the same trap after you snake it. If that is happening, you need a drainage project, not another dose of drain cleaner.
We work across south east Melbourne, including Knoxfield, Rowville, Ferntree Gully, Berwick, Cranbourne, Glen Waverley and Endeavour Hills. Jobs outside that belt are quoted when the roster can cover them. Call 1300 575 862 or use the contact form.
On a level subfloor, waste water has nowhere to run. Solids settle in the 100 mm line, the next flush sits on top, and both male and female blocks fail in the same week. That is what we found on a Preston amenities job after a free site assessment. The staff had not been flushing the wrong items. The pipework was the fault.
Other commercial causes we see are collapsed clay, grease from a canteen, roots at the boundary, and stormwater tied into sewer. A blocked drain clear can get the cubicles open the same day. If the camera or a water test shows no fall, the next step is a quoted replacement of the suspended sewer, then a Victorian Building Authority compliance certificate on the notifiable work.
Trade waste and kitchen lines sit next to this work. If the blockage is in a cafe or restaurant, start on our restaurant and cafe plumbing page. Larger plant belongs with commercial plumbing or a commercial hot water upgrade booked in a shutdown window.
A full commercial drainage service covers assessment, pipe replacement, flooring reinstatement, testing and a compliance certificate, with one site contact. On the Preston toilet blocks we stripped suites and partitions, lifted vinyl and timber, cut out the old 100 mm suspended sewer, installed new PVC to the existing below-ground riser, relaid the floor, and put the amenities back together. Basins and urinals stayed in place. Rubbish left with us.
We do not send you to a second contractor for the vinyl or the partitions on a job of that type. That is the point of a single quote. After-hours or holiday access is arranged when a live tenancy cannot lose both toilet blocks at once. Emergency backups still go through the 24/7 emergency plumbing line.
Preston is the job on this page, not our home suburb. The client had repeat blockages in both toilet blocks at the rear of the building. We assessed, quoted the full drainage and flooring scope, and completed the list you see below. They wanted one company on the keys so the tenancy did not juggle three trades.
That same method is how we quote south-east sites: write the isolations, name the pipe size, say what stays, and say who issues the certificate. Related project pages include commercial fire service and industrial roof plumbing.
Send the address, photos of the amenities, and when we can isolate the line. We reply with an obligation-free quote. If you already have a preferred-contractor panel, say so so we bring the paperwork. Call the number in the first section or use the contact page.
We do not publish a price band here because a vinyl lift and a boundary sewer are different jobs. The quote lists the pipework, the floor, the certificate and the access hours. If you only need a clear today, ask for that first.
