Ask Plumbers (Public) / Re: Hot water causing pipes to make a loud banging noise

Hi Ladybird,

Expanding pipes causing noise is BS. You certainly have the right to live in a home with no banging pipes. I have come across many banging pipes during my carrier and there is simply too many causes to point to one thing. Reasons start with bad plumbing right through to cheap imported fittings.

Either way, you need to document this fault and submit a complaint with the builder (whoever your contract is with) and request for this to be fixed. If they refuse you can report this to the PGDB requesting an investigation. You may also engage a property / council inspector to provide a report which I assume will cost you a fee. I would try to get images of the plumbing done as this may indicate what the problem is right away.

Good luck with this.   
Ask Plumbers (Public) / Hot water causing pipes to make a loud banging noise
« Last post by Ladybird on August 15, 2018, 07:13:55 PM »

When the hot water tap is turned on in the bathroom on the third level, you can hear this loud banging noise on the 3rd and 2nd floor.

The bangs start to happen about 10-15 seconds after the hot water tap has been turned on. There is a bang every 3-4 seconds and this banging noise continues for a little while after the tap has been turned off.

This unit was built in 2017 and is just over one year old. This banging noise started from day one.

I have heard from a professional that this noise be related to the pipes expanding and possibly not have enough space to expand.

Questions I have:
Do I have the right to have this noise/ this issue rectified?
Is it legal to install pipes in such a way that they make this horrendous prominent noise?[/color][/size][/font]

I have heard that apparently now the PGDB have changed their policy to prevent excessive emails....from unreasonable people....

Here is an idea.....answer the questions.....that's reasonable....

I have received no replies to these emails….so I am guessing that a system of governance that stands by telling untruths when someone is nearly killed by a preventable explosion which then blames the innocent and lets the guilty go free is all ok with you? Protecting them selves before the NZ public?

You should all go take a good look at yourselves.

Hi Robbo, not externally. Im talking about inside the tank and submerged under the water if the element has a crack it will arc under water and cause a banging noise. This is not uncommon when the element is on its way out or damaged for other reasons.

hi guys, yeah very strange, i suppose expansion and contraction could let a drop or two in then seal before arcing but i imagine that the element would slightly `faulty`from new, long shot but.... cheers

had that happen here 3 years ago when the council "upgraded the water treatment plant"
100s of hot water cylinders aged from 4 years to 40 years all started to leak from pin holes,
cut a cylinder open and the copper sulfate crystals had eaten clean through the copper bottom.
i did some on line research and all info pointed to a increase in ph ( potential hydrogen) levels feeding the copper sulfate and they would grow and eat copper like it was ice cream :D :D :D :D :D
merchants where rubbing their hands together for nearly 2 years!
poor customers had no idea and council played the 3 moneys act  >:( >:( >:( >:( >:(
high ph plus water at or above 60c = copper sulfate grows like crazy

corys sell very fine long electrical screw drivers that will do the low flame bypass adjustment, i have 2, one i had to grind down the shaft just to do a single job, think it was a classique  from memory.
 i would not recommend gameco manometers, i have had 4 of them and all failed within 2 years, not water proof, dont leave in the sun as the display disappears, basically rubbish.
try a sce digitron 
  :D ;)

surely a arcing element would pop a circuit breaker or rcd !due to earth leakage

what model coopers is the cylinder? stainless steel coil wet back by any chance ?

When Hastings was first chlorinated heaps of cylinders went there. They found that the chlorine was cleaning out the pipe work and Hot Water Cylinders, which was causing the leaks. The councils network sprung a lot of leaks also, city care were kept busy digging up the roads to carry out the repairs
