Cloudy, hot water looks yuck.
Why is my hot water cloudy is one of those perennial questions that arise for the plumbing technicians at Whywait Plumbing?
Generally, the problem is based around reoccurring issues of, “what do you think causes cloudy (white not dirty) water that comes out of the kitchen tap when on hot. It doesn’t do it on cold, and if you boil cold, you don’t get the same residue. The photo attached is the residue after 30 seconds when the water settles.”
Very simply in most cases, cloudy, hot water is caused by dissolved gases in the water. We assure you it is safe to use.
To get cloudy water from your hot tap, you have to create the right set of circumstances for everything to come together at the same time.
So why is my hot water cloudy?
To explain this a little more, you have to understand that all your water is stored in your water pipes under pressure. Therefore water under pressure has a higher capacity to hold dissolved gases. When water under pressure is heated the ability to hold those dissolved gases is reduced.
Primarily what happens then that is your cold water is heated in a water heater it creates hot water under pressure. This results in supersaturation occurring with dissolved gases. Ultimately those gases are released when you turn on the hot kitchen tap.
Another way to look at it is that when you turn the hot tap on you create that same kind of effect as when you pop the cork off a bottle of champagne because all that pressure has to go somewhere.
Why hot water is cloudy when you first turn on a tap?
The reason your water is milky or cloudy when you first turn the water tap on is that turning on the tap releases the pressure. This pressure release is often an initial highly pressurised burst. Because the dissolved gas comes out of the water in the form of tiny gas bubbles right throughout the water filling a glass or container. The gas bubbles then rise to the surface of the water and burst so that the water has a cloudy or milky appearance.
The cloudy, hot water will clear in a few seconds. As it is gas bubbles dissolving the water will clear from the bottom up. You can easily observe in a glass the water rapidly clearing from the bottom up.
The good news is that dissolved gas or air in water in reasonable quantities is not uncommon and means that the water is in a “healthy” condition.
We guarantee cloudy water does not mean you have defective hot water service or your water is contaminated. Generally, gas bubbles in your hot water supply will increase with the increase in temperature of your water because of the hotter your water, the lower the number of gas bubbles that can be held.
What should I do if my hot water is always cloudy?
If after the initial burst of hot water, your water is continually cloudy then it needs further investigation. Gas bubbles do not cause the cloudiness that does not dissolve in hot water.
Seldom is it a fault with your hot water service. If the water does not lose the cloudiness within thirty seconds, you likely have a water filtration problem or a sediment buildup in the hot water tank.
Investigating cloudy, hot water needs to be undertaken by a licensed plumber so if you are continuously asking yourself why is my hot water cloudy you need to call us at Whywait Plumbing on (07) 5580 4311 and book a site visit.
The Easter long weekend is only surpassed by the Christmas and new year period as a time when families travel to be together. It is also the start of the hot water season when clients are reminded of the ever-increasing hot water electricity cost.
For the plumbers at Whywait Plumbing, Easter is a busy period with blocked drains being the most common problem followed by hot water problems.
Unlike Christmas, there is always a spike over Easter in emergency callouts for faulty hot water units. That is because Easter is generally much cooler than Christmas. Around April, we all suddenly realise that cold weather is on the way. Every year we notice the signs with an increase in emergency service callouts with the problem being no hot water. Even in the relatively mild climate of South-East Queensland no-one willingly wants to have a cold shower.
Frequently we cannot help but shake our head’s at all the stress, the waste of time and money these emergency service calls represent to many homeowners. Sadly many of us do not pay too much attention to the myriad of household and mechanical systems that provide so much comfort and convenience in our modern lives. We take for granted our water heaters, toilets, mixer taps, and air conditioners that is until they stop working. Then come the panicked call and a repair job that always ends up costing more than we expect.
Showers are the activity where we use the most hot water. Generally, 40% of the water consumed in the shower is hot water. This is why there is a strong correlation between the length of a shower and the hot water electricity cost.
If your home is like many in South East Queensland you are producing hot water from an electric hot water service connected to tariff 11 with a shower rose you love because you get a deluge of water from it at 23 litres per minute. If your shower is being utilised four times a day for an average of 5 minutes per shower, then those showers are costing you $1125 a year in electricity costs and $107 in water usage costs.
Essentially 1 kilowatt-hour of electricity is used to produce 15 litres of hot water using an electric element hot water service. With electricity prices expected to increase 21% on 1 July and a further 40% over the next three years, there is considerable scope for reducing your hot water electricity cost.
One option is to change your electricity and water guzzling shower rose to a water efficient shower rose using only 9 litres per minute. Based on the standard example above this would immediately reduce your electricity costs to $440 and water cost to $42. If you are able to change your hot water service from tariff 11 to tariff 33, then you will save an additional 40% on electricity costs.
The best option and the one we recommend is the long-term sustainable option utilising heat pump technology. Heat pump technology involves replacing your old fashioned energy-hungry electric hot water service to the highly efficient Sanden “Eco®” Plus Heat Pump hot water system.
Electricity costs have become a political hot potato, with state and federal governments playing the blame game in blaming each other for the doubling of electricity prices in recent years.
Hot water electricity cost is one area you can reduce your electricity costs substantially by being smart about how you heat your hot water and use it. Hot water generated by electric elements is something we always took for granted. That is until surging electricity price increases made us all take another look at our increasingly energy-intensive lifestyles.
Increasingly Gold Coast home owners are being subjected to allegedly “free compliance audits” by plumbing inspectors from Gold Coast City Council. To justify their jobs in a depressed market with almost nil construction activity Gold Coast City Council plumbing inspectors are acting like desperate door to door salesmen knocking on the doors of home owners who have had hot water systems upgraded. There is no legislative requirement for these audits to occur and there is no requirement by the home owner to allow them to enter their home.
To fill in time and justify their jobs Gold Coast City Council plumbing inspectors are undertaking “audits” that are not requested and are unannounced. The plumbing inspectors are knocking on the door and stating they are there to inspect the hot water service. Legally they are able to assess the work if invited to do so by you. No Gold Coast plumber is asking them to assess the work as none of us see any value in doing so. Neither Gold Coast City Council or its plumbing inspectors take any risk or responsibility, so their inspection is of no real value except to justify their own jobs.
If a Gold Coast City Council plumbing inspector arrives unannounced at your door then he has no right of entry. He may request entry by your invitation to inspect work that pertains to the form 4 plumbing contractors are legally obliged to lodge, but that is the absolute limit. If you refuse him entry then he must immediately depart. Unfortunately the plumbing inspectors are loose with the truth and make out that they are legally obligated to undertake this audit and do not inform home owners that it is optional and not a legislative requirement.
The individual plumbing inspectors are not to blame for these events but are forced to do so as they work in an appalling atmosphere at Gold Coast City Council. It has been common knowledge within the plumbing industry for many years that the Gold Coast City Council plumbing inspectors are a deeply troubled organisation with bullying, abuse of power, nepotism, cronyism and double standards a daily occurrence.
A number of clients of Whywait Plumbing that have received these unexpected visits have been shocked when we have phoned to say their hot water service we installed 6 months ago has had a defect notice issued. In every instant as long as Whywait Plumbing receive the defect notice we undertake the “repairs” which invariably are that the tempering valve that is legally required to deliver hot water at 50 degrees is over temperature. To date every home we have returned to is between 1-3 degrees over temperature. To see more information on the requirements of tempering valves click here.
Many of our clients have told us that they do not want the plumbing inspectors returning to their homes to re-audit. This we have conveyed via email to Gold Coast City Council plumbing inspectors on behalf of our clients. As a result we had a phone call from the Gold Coast City Council plumbing & drainage supervisor, Brian Till recently who informed us we should be encouraging our clients to have the re-audit undertaken otherwise we will remain responsible for the defects despite our notifying Gold Coast City Council that rectification work has been undertaken. Furthermore Brian Till advised that the property will have registered against the title that there are outstanding plumbing defects which can have severe financial repercussions if you wish to sell your home.
Our recommendation if you get an unexpected knock on the door from a Gold Coast City Council plumbing inspector is that you decline to allow them entry to the your home. Declining entry has no repercussions for you as they walk away and the file is closed.
However if you have had a defect notice issued then we recommend that you allow a re-audit at a time that is suitable for you to ensure no defects are registered against your property. If you desire we will attend at no cost, to give you reassurance and to ensure that due process is complied with.
