Signs you have a drainage problem in Halswell
Drainage faults rarely announce themselves, and the warning signs differ depending on which system you are on.
- An alarm on a pump sewer unit Or a warning light you have not seen before.
- A pump running more often More frequently than it used to.
- Slow or backing-up gully trap Especially after a downpour.
- Drains gradually getting slower Especially noticeable since the earthquakes.
Any of these are worth a look. Call us on 03 379 0711 and we will CCTV the line before quoting anything.
Local
What is under your Halswell property depends where you are
Halswell is two suburbs as far as drainage is concerned, and most homeowners do not know which one they are in.
Newer Halswell homes generally run on a pump sewer system. Instead of gravity carrying waste away down a sloped pipe, a pump moves it out to the main. That is a completely different system to maintain, with different failure modes, and it matters a great deal if you are planning to alter anything or add a new connection.
Older Halswell properties are more likely to be on traditional clay drainage. Some of that clay sat through the earthquakes and was never formally assessed afterwards, so damage that has been there since 2011 may still be sitting in the ground.
Fall matters more here
Halswell homes tend to sit well back from the road on larger sections. That means longer drainage runs, and over a long run the fall has to be right from the start. Get it wrong and waste does not move the way it should, which is far more expensive to fix after the fact than to get right at the outset.
Granny flats and sleepouts
Larger sections also mean we get asked about granny flats and garage-to-sleepout conversions more in Halswell than almost anywhere else. Both need drainage connected properly to whatever system the main house is on, which is the first thing we check.

Underground
What is probably under your Halswell property
Drainage is the one part of a house nobody ever sees. Here is what we usually find, and what it means for any work you are planning.
-
Newer build
A pump sewer system Different maintenance, and new connections need designing for it.
-
Older property
Traditional clay drainage May carry earthquake damage that was never formally assessed.
-
Set back from road
A long run out to the main Fall has to be right across the whole length, not just at the house.
-
Large section
Room to build, and drainage to think about Granny flats and sleepouts need their own properly connected drainage.
Our process
How we find the problem before we dig
The first job is working out what system you are on, because everything after that depends on it.
Identify the system
Pump sewer or gravity clay. It changes how we diagnose a fault, what a repair involves and what a new connection needs, so it is the first thing we establish.
CCTV the line
We run a camera through the drain and see exactly what is there. On older clay that also shows up earthquake damage nobody has looked at before.
Quote the real fix
Once we know what is down there we quote it properly, including the fall the run needs if the house sits well back from the road.

Recent drainage work in Halswell
Whitehead Plumbing & Gas work across Halswell regularly. Here is some of what we have been doing in the area lately.
-
Sewer drain extended for a sleepout on Wales Street
Extended the sewer drain to serve a new sleepout at a Wales Street property. Getting the fall right over the extra distance is the part that matters, and it is easier to plan at the start than to correct afterwards.
-
Drainage fault found and repaired on Caulfield Avenue
Investigated a drainage issue at a Caulfield Avenue property and repaired it. We CCTV the line first so the repair is based on what is actually wrong rather than where it is easiest to dig.
Ben leads our drainage work. We send whoever is closest and best suited on the day though, so you are not waiting on one person.

Frequently Asked Questions
Halswell Drainlaying Questions
How do I know if my Halswell home has a pump sewer system?
Newer Halswell homes generally do, older ones generally do not. If there is a pump unit or a control box on the property, that is a strong sign. If you are not sure, we can check it as part of any drainlaying job, and it is worth knowing before you plan any building work.
I am adding a granny flat. What drainage does it need?
Its own connection, properly tied into whatever system the main house runs on. That is a different job depending on whether you are connecting into a pump system or a gravity line, so the first thing we check is which you have. Fall matters too, especially on a long run.
Can I convert my garage into a sleepout and add drainage?
Usually yes, and it is one of our more common Halswell jobs because sections here are larger. The drainage has to be connected correctly and the fall worked out from the start. We would look at it on site and quote the work, including whether council consent is required.
Could my drains still have earthquake damage nobody has looked at?
If you are on older clay drainage, it is possible. Some Halswell clay was never formally assessed after the earthquakes, so damage can still be sitting in the ground. A CCTV inspection shows you exactly what is there.
Why does fall matter more in Halswell?
Homes here tend to sit well back from the road, which means a long run out to the main. Over that distance the fall has to be right from the start, because waste that does not move the way it should is far more expensive to fix after the fact.
Do you handle urgent blocked drains in Halswell?
We respond to priority repairs during business hours. Call us and we will dispatch the nearest qualified drainlayer and give you an estimated arrival time. If we cannot get there soon enough, we would rather recommend another trusted tradesperson than leave you waiting.
