What are erosion and corrosion in your water pipes?

At Whywait Plumbing, we understand the importance of protecting your plumbing and infrastructure from damage caused by erosion and corrosion. These processes can cause significant damage to pipes, fittings, and other components, leading to costly repairs and even complete system failures. In this blog post, we will discuss the causes of erosion and corrosion and the steps you can take to prevent or mitigate these issues.

Erosion is the gradual wearing away of materials caused by the movement of water, air, or other natural elements. This can happen in various ways, including water flowing through pipes, air passing over metal surfaces, or even soil movement around underground pipes. Erosion can cause damage to the surface of pipes, fittings, and other components, making them more susceptible to leaks and other problems.

Conversely, corrosion is the gradual destruction of materials caused by chemical reactions to the environment. For example, this can happen when pipes and fittings are exposed to water containing dissolved oxygen, acids, or other harmful chemicals. As a result, corrosion can cause damage to the surface of pipes, fittings, and other components, making them more susceptible to leaks and other problems.

Temperature and high water pressure velocity are the leading causes of erosion and corrosion in your water pipes.

High velocity or high pressure over a long period can cause the internal pipe surface to corrode, eventually leading to pinholes in the pipes.

Your hot water pipes are even more susceptible to erosion and corrosion as they age. In commercial buildings or older homes without tempering valves, the circulating hot water temperature is usually over 60° C which, combined with high pressure, creates a high risk for erosion and corrosion.

Repercussions of eroding water pipes and the consequences

Erosion and corrosion in your hot and cold water reticulation pipes can have multiple consequences, resulting in costly plumbing rectification work. The most common issues will be:

High water bills with significant amounts of wasted water leaking through underground pipes.
Corroding pipes leads to reduced flow rates, especially if you have copper pipe or galvanised piping.
Failure of critical infrastructure, especially in commercial buildings.
Both erosion and corrosion weaken the structural integrity of pipes leading to leaks that cause damage to buildings structurally and to furniture and possessions.
High-pressure velocity and the breaking down of pipes internally can create failure in valves such as toilet cisterns and hot water systems.

Which water pipes are most at risk from erosion and corrosion?

With the right combination of temperature and high-pressure water velocity, all piping systems are at risk of erosion and corrosion. Listed below are pipe types and their risks.

Copper – copper piping is most at risk of internal and external erosion and corrosion. Externally mainly if laid in concrete or underground the pipe needs to be fully covered by impervious wrapping such as Denso tape. Copper is the most at risk pipe from high-pressure water velocity corroding the internal pipe surface.
Pex – pex piping has a much more significant internal and external tolerance to erosion and corrosion. As with all pipes, high-pressure water velocity can still damage the pipe internally over time.
Polyethylene or Poly Pipe – poly pipe is mainly used externally underground and, if installed correctly, has significant internal and external tolerance to erosion and corrosion. As with all pipes, high-pressure water velocity can still damage the pipe internally over time.
Stainless Steel – stainless steel piping is frequently used in commercial buildings as it has highly significant internal and external tolerance to erosion and corrosion. As with all pipes, high-pressure water velocity can still damage the pipe internally over time.

The photo above is a pipe we removed and sent to Kembla for testing, as our client had suffered multiple leaks in both hot and cold pipes. They then cut and sectioned the copper pipe longitudinally to examine the internal surface in more detail. The interior surface was observed to have a well-formed black oxide layer partially covered in a layer of fine light brown silt. Multiple corrosion nodules were observed running the entire length of the cross-section. Most of these corrosion nodules are covered in fine brown silt. Brown silt was removed from several corrosion nodules to determine what was underneath. It was observed in many of the corrosion nodules the silt crust was hollow, with a void or air bubble immediately under the surface, under that a layer of corrosion product was sitting at the surface of the tube. The corrosion products were shown to be a loose mixture of black copper oxides and blue-green copper carbonate corrosion products.

Preventing erosion and corrosion?

Preventing erosion and corrosion is essential to protecting your plumbing and infrastructure. One of the most effective ways to do this is by using materials that are resistant to the effects of erosion and corrosion. Stainless steel, for example, is highly resistant to corrosion and can be used in various applications. Other materials, such as plastics and copper, can also be used to protect against erosion and corrosion.

Another essential step in preventing erosion and corrosion is properly maintaining your plumbing and infrastructure. This includes regular inspections and repairs and proper cleaning and maintenance of pipes, fittings, and other components. In addition, it is essential to protect your plumbing and infrastructure adequately from the elements by using coatings and other protective measures.

It is also essential to be aware of any potential sources of erosion and corrosion in your area. This can include heavy rainfall, high water table, or even nearby construction projects. By understanding the specific risks in your area, you can take steps to mitigate or prevent damage caused by erosion and corrosion.

What do you need to do to prevent a high plumbing bill?

Individually, you cannot do much to protect your plumbing water pipe infrastructure. The critical step you should take is for Whywait Plumbing to undertake regular inspections and preventative maintenance. We need to ensure the following:

Your water pressure does not exceed 500 kPa by ensuring a fully functioning pressure reduction valve after your water meter. This eliminates the risks created by high-pressure water velocity.
Your hot water does not circulate above 50° C, requiring fully functioning tempering or thermostatic mixing valves. This eliminates the risk of internal erosion of pipe surfaces due to water temperatures over 60° C.

In conclusion, erosion and corrosion are serious issues that can cause significant damage to your plumbing water pipe reticulation infrastructure. However, using materials resistant to erosion and corrosion, correctly maintaining your plumbing and infrastructure, and being aware of potential sources of erosion and corrosion can help protect your property and avoid costly repairs. At Whywait Plumbing, we are committed to helping you protect your property from the effects of erosion and corrosion.

If you have any concerns about the condition of your plumbing and infrastructure, please don’t hesitate to contact us for a consultation. We’re here to help and ensure your plumbing is in top shape.

Can I install a bidet seat or douche hand spray to my toilet?

DIY Bidet Seat and Douche Hand Spray Installations Are Illegal and Non-Compliant

Since the Covid-19 pandemic and the infamous toilet paper shortages, we are getting asked about installing bidet seats or douche hand sprayers. Many of these enquiries eventuate from sponsored posts on Facebook promoting the DIY installation of bidet seats. The photo above perfectly illustrates a DIY bidet seat installation we recently encountered in a client’s home.

We commonly come across these DIY bidet installations in clients’ homes. Unfortunately, we are then placed in the invidious position of informing them that this is an illegal installation that requires disconnecting as it has no WaterMark approval and is not compliant, as required by the Plumbing and Drainage Act 2018.

Unfortunately, we are only the messenger, but immediately, too many people believe we are wrong. This occurs as the online company they purchased the bidet seat from told them they could install it themselves.

Illegal DIY Installations Can Effect Your Home Insurance Cover

Imagine how we feel when explaining to a disgruntled client that their DIY bidet installation is not legally compliant. Then explain that if it fails and floods their home causing tens of thousands of dollars of damage, their insurance company will null and void insurance protection.

Despite what Facebook posts say, very few legal DIY plumbing installations exist. Your insurance policy requires a licenced plumber to undertake all plumbing work with all plumbing fixtures installed with the necessary WaterMark approval.

Avoid Online Retailers, and Only a Licensed Plumber Can Install a Bidet Seat or Douche Hand Spray

Bidets, bidet seats and douche hand spray bidets are popular with the elderly and people with disabilities. Correctly installed, they afford their users self-care toileting which aids their independence, plus they are much more hygienic than toilet paper.

If you are looking into bidet seats or a douche hand spray, only purchase them from reputable Australian suppliers. Avoid online retailers with no prominent Australian location and not displaying a WaterMark approval.

No matter what, you must use a licensed plumber to install the bidet seat or douche hand spray to ensure there is no risk of backflow. A backflow situation can risk your family and neighbours consuming sewerage-contaminated drinking water.

A legally compliant installation by a licensed plumber required lodgement of Form 9 with the local council and lodgement and payment of fees for Form 4 with the Queensland Government QBCC. You should always get a copy of both forms to prove to your insurer that it is a compliant installation.

Legally Installed Bidet Seat or Douche Hand Spray Offer Benefits in Terms of Hygiene and Independence for the Elderly and People With Disabilities

Remember, if you install a bidet seat or a douche hand spray, you need to do the following:

Purchase a WaterMark-approved product
Only use a licensed plumber to install your bidet products
All installations require high-hazard backflow prevention

Compliance with these requirements will ensure the safety and well-being of your family, protect your home from potential risks, and maintain insurance coverage.

A bidet seat should not be confused with a bidet. A proper bidet must go through an entire approval process by council plumbing inspectors.

Like everything in life, you only get what you pay for, so we recommend you stay away from online retailers, especially on Facebook.

The adage applies when finding cheap DIY bidet seats or douche hand spray hoses. If something sounds too good to be true, it probably is.

Water Damage Insurance Claims Are Still Increasing

Water damage insurance claims are an issue we deal with every week. We are continually called upon to deal with insurance companies or assessors on behalf of clients when they have sustained water damage to their homes.

With COVID-19 lockdowns keeping a large proportion of Australians at home, research from QBE Insurance indicates water damage insurance claims remain at high levels.

New research from QBE Insurance revealed that 77% of people who experienced water damage were home at the time of the incident, unravelling misconceptions that flooding mainly occurs when the house is unoccupied.

The QBE Insurance research statistics reveal that:

77% of claimants impacted by water damage were at home for the water damage incident.
Burst pipes, blocked pipes, damaged roofs and old plumbing are the main water damage culprits.

According to the research, internal water damage is typical, with 58% of survey respondents having experienced internal water damage themselves or know someone who has, or both.

This coincides with QBE claims data, which found water damage incidents account for almost a quarter (24%) of all home insurance claims. Water damage insurance claims are one of QBE’s most regular home insurance claims. An average claim is $5,000, and more severe water damage claims commonly reaching over half a million dollars.

“Preparedness and prevention are key to limiting the potential damage caused by internal water damage,” says Arron Mann, General Manager, Short Tail Claims at QBE.

“Water damage can happen whether a household member is at home or not being home more often, as many of us are right now, can increase the pressure on our plumbing and risk to our homes. However, this kind of damage can also be sudden and severe regardless of whether you’re home or not, which is why prevention and knowing what to do when something goes awry are so valuable.”

Despite 53% of research respondents saying their first response to water damage would be turning off the water main, 1 in 5 Australians (21%) don’t know where their water main is, and worryingly, 1 in 5 (18%) also don’t know how to turn it off.

The QBE research also revealed that almost 30% of Australians don’t know what home maintenance tasks can prevent water damage in their homes, with 16% not knowing that home maintenance can prevent it in the first place. Cost is also a factor, with 21% not undertaking any home maintenance because it’s too expensive, while 8% say they don’t have the time.

“Sometimes, the difference between no damage and severe damage can be in how quickly a householder responds. Yet concerningly, many people are unaware that much of this damage – and the stress and cost that comes with it – is often preventable,” says Arron Mann.

The best way to avoid water damage insurance claims is by regular maintenance from Whywait Plumbing. Now this will not prevent every possible water leak scenario from happening, but it will demonstrate to the insurance company that you have been undertaking regular maintenance if claim difficulties occur.

At Whywait Plumbing, we see instances every day of water damage that has occurred through the failure to maintain your home regularly. That is why we recommend all our clients to become a Service Partner and enjoy the VIP benefits of having a Service Partner Plan to maintain your most valuable asset, your home, proactively.

Will PEX Pipes Create a Strange Taste in Drinking Water?

Traditionally most homes used copper pipes to circulate hot and cold water. Since the 1970’s plastic pipes have increasingly replaced traditional copper or galvanised steel pipes.

Over the last ten years, pipe-in-pipe systems have been commonly installed to circulate water in most newly constructed homes. The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX).

Since the advent of plastic plumbing systems, there have always been questions regarding the effects on health and do they affect the taste and odour of drinking water. International studies have shown that plastic pipes can release substances that give drinking water an unwanted taste and odour. It has also been suggested that some of these substances may be carcinogenic.

Several investigations worldwide on health issues have been conducted, and most are inconclusive or positive. The Norwegian Institute of Public Health has just released a new study on whether leaching or leakage products from these pipes harm health and if they affect the taste and odour of drinking water. The potential leakage products consist of residues of additives used during manufacture to give plastic pipes their desired properties and any subsequent breakdown products.

The Norwegian study results indicated:

There are no health risks associated with drinking water from PEX pipes
A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time
Although the taste and odour usually dissipate with use, water from two PEX types still had an unpleasant smell and taste after a year.
The volatile organic compounds that leaked from new PEX pipes were generally low.
The level was further reduced with the use.
No correlation was found between manufacturing methods and leaking products.

This study was undertaken far more scientifically than many tests or studies in Australia. It is common in Australia for international products that have undergone extensive testing to fail AS4020 based on a highly subjective taste test from a panel of 5 – 7 people. The Norwegian study tested ten different PEX pipe types for leaching products in a standardised laboratory test. The water was in contact with the tubes for 72 hours.

Three different manufacturing methods produce pipes known as PEX-a, PEX-b or PEX-c. These methods use slightly different additives, but this study found no correlation between production methods and leakage products. Two of the most commonly occurring substances detected in the experiment’s water were 2.4-di-tert-butyl-phenol and methyl-tert-butyl ether (MTBE). For three new pipe types, MTBE was detected in higher concentrations than the US government’s recommended limits for the taste and odour of drinking water (USEPA). Still, the values were reduced to below this limit after the tubes were used for a while.

This study confirms what the plumbing technicians at Whywait Plumbing frequently observe: no matter what type of pipe, there can be a taste or odour in new piping systems or where a house has been unoccupied. The taste and odour soon disappear once the water is in use in the house and is in constant circulation.
