Alexandria is a suburb built for industry and now largely lived in. Warehouse conversions, new apartment blocks and remaining commercial premises sit side by side, often sharing drainage that was designed for none of them.

The recurring issue in converted buildings is drainage doing a job it was not designed for. Industrial waste lines retrofitted to serve kitchens and bathrooms frequently have the wrong fall or the wrong pipe size, so a shower that drains slowly is a design problem rather than a blockage. Working out which is the first job, because they have very different fixes.

$0 call-out fee — available 24/7, 365 days a year across Alexandria and nearby suburbs.

Every part of Sydney has its own plumbing character, shaped by the age of the housing, the ground it sits on, and the weather it takes. Here is what we are called out for most often around Alexandria.

Industrial buildings converted to residential often run waste through lines never intended for it. Slow drainage that has always been slow is usually fall or pipe size, not a blockage.

Mixed-use buildings put commercial kitchens on shared lines. Grease sets and narrows the pipe well upstream of where it entered, causing blockages that seem to come from nowhere.

Some lines here are old, oversized, and made of materials no longer used. A camera inspection is the only reliable way to establish what you actually have before quoting work on it.

Common Questions

If it has always been slow rather than getting worse, it is usually insufficient fall or undersized pipe from the conversion, not a blockage. A camera inspection confirms it and avoids you paying to clear a line that is already clear.
