A water leak caused by DIY plumbing cost this owner $10,000+ in repairs

What are the steps for water leak detection?

The Nu-Trend plumbing team was called to perform a water leak detection service in Sydney for a property owner could hear water constantly running even when all the taps were turned off. 


1. We conducted a site inspection and decided to pump the hot and cold water lines with a nitrogen test and found there wasn’t a drop in water pressure.




2. We then tested the drainage with a Fluro Dye test and couldn’t find any leaks that way. 



3. We asked permission from the owner to cut a small hole in the side cupboard so that we could test the water proofing by spraying the shower head onto the tiles. We instantly identified a pool of water underneath the bath and large amounts of water leaking through the wall.



So we determined it was failed water proofing of the bathroom wall. If it was left as it was there would continually be water leaking into the wall cavities and causing lots of damage. As it was a two storey apartment and on the top floor there wasn’t a quick fix possible as it could lead to damage of the other apartments on the lower levels. 



So to repair the waterproofing for this small bathroom in an apartment block we would need to;

  • Strip the bath cubical including the Gyprock walls.
  • Re-sheet the walls.
  • Re-install the cornice.
  • Re-water proof 3 times with primer and water proofing.
  • Re-build a new bath hob.
  • Replace the bath drainage and breach piece (while it’s exposed)
  • Supply and install a new bath, bath mixer and shower head.
  • Re-tile the walls
  • Do new grout and sealing.
  • Re-paint the patched ceiling and cornice
It means it is up to $10,000 in repairs to fix this problem correctly and it was caused by a simple water leak from bad water proofing.

Is DIY Plumbing a good idea?

Attempting a DIY Plumbing job in lots of cases is just not a good idea. For this property owner the damage they caused from the water leak from their attempted DIY Plumbing repair cost over $2,000 in temporary repairs to their wall and floor from water damage. It could have been avoided if they had booked a domestic plumber that would have cost around $100.


A lot of plumbing problems may look like they are easy to fix such as replacing a tap or fixing a leak. Although in many cases if that isn’t done properly you can cause other plumbing issues without even realising it. Or some situations might actually be hiding underlying issues with the plumbing at the property that is deeper in the system of piping that you can’t see.


That is why it pays to get a professional domestic local plumber who is licensed, qualified and insured for this type of work like fixing shower head leaks.


What damage can be caused by a DIY Plumbing Job?

In this example the Client had followed a YouTube video about how to replace a shower head. They thought a DIY plumbing repair job like this looked easy so they used a shifter on the hex and put it back on with Teflon pink sealant tape. Although what wasn’t mentioned in the video was to silicon seal the gap between the hex nut and the tile.



So it became a double whammy, the Client didn’t apply the Teflon tape correctly and there was no silicon seal either. Therefore water was leaking behind the wall and into the tile bed and carpet of the adjoining room. 



Plumber to replace your leaking showerhead costs about $110 plus GST.



To repair the damage in this situation cost $2,200 plus GST



For a short term repair we had to;

– Identify the source of the water leak and damage.

– Remove the showerhead. 

– Reseal the gap between the wall tile and shower head backplate with sealant.

– Seal the thread correctly.

– Wet vacuum the water from the carpet and as much out of screed through the grout joints as possible.

– Hire an industrial fan to help dry the area as much as possible.

– Re-instate the damaged carpet 

How much does it cost to repair a leaking shower head?

You can get a local domestic plumber to replace your leaking shower head for as little as $110 plus gst to make sure the job is done correctly and to inspect for any potential water damage in the bathroom.
